What is
lim sin(x) in the graph shown?
Therefore, we can say: limit sin(x) as x approaches pi/2 does not exist lim sin(x) as x approaches 0 = 0.
What is the sinx x wiki's maximum size?Although the function (sin x)/x is not defined at zero, it approaches 1 arbitrarily close as x approaches zero. In other words, when x gets closer to zero, the limit of (sin x)/x = 1.
Why does Sinx have no limit?We can put g(x) equal to -1/x and h(x) equal to 1/x because sin(x) is always between -1 and 1. As x approaches either positive or negative infinity, we know that the limit of both -1/x and 1/x is zero, and as a result, the limit of sin(x)/x is also zero.

The correct answer is D. Trapezoid EFGH is congruent to Trapezoid ABCD after undergoing transformation D.
How to Determine if Trapezoid EFGH is congruent to, an enlargement of, or a reduction of Trapezoid ABCD.Let's first define the transformations:
A. Translation down, followed by rotation of 90°, followed by dilation by a scale factor of 3.
B. Rotation of 45°, followed by a reflection, followed by a translation left.
C. Dilation by a scale factor of 12, followed by a translation up, followed by a reflection.
D. Reflection, followed by a dilation of a scale factor of 1, followed by a rotation of 180°.
To determine if Trapezoid EFGH is congruent to, an enlargement of, or a reduction of Trapezoid ABCD, we need to analyze the effects of each transformation on the trapezoid.
A. Translation down, followed by rotation of 90°, followed by dilation by a scale factor of 3.
This transformation involves moving the trapezoid down, rotating it 90 degrees clockwise, and then increasing its size by a scale factor of 3. This transformation does not preserve angles or side lengths, so Trapezoid EFGH is not congruent to Trapezoid ABCD.
B. Rotation of 45°, followed by a reflection, followed by a translation left.
This transformation involves rotating the trapezoid 45 degrees clockwise, reflecting it across a line of reflection, and then moving it left. This transformation does not preserve angles or side lengths, so Trapezoid EFGH is not congruent to Trapezoid ABCD.
C. Dilation by a scale factor of 12, followed by a translation up, followed by a reflection.
This transformation involves increasing the size of the trapezoid by a scale factor of 12, moving it up, and then reflecting it across a line of reflection. This transformation does not preserve angles or side lengths, so Trapezoid EFGH is not congruent to Trapezoid ABCD.
D. Reflection, followed by a dilation of a scale factor of 1, followed by a rotation of 180°.
This transformation involves reflecting the trapezoid across a line of reflection, then increasing its size by a scale factor of 1 (i.e., not changing its size), and then rotating it 180 degrees. This transformation preserves angles and side lengths, so Trapezoid EFGH is congruent to Trapezoid ABCD.
Therefore, the correct answer is D. Trapezoid EFGH is congruent to Trapezoid ABCD after undergoing transformation D.

Katte is buying plants and soil for her garden. The soil cost $4
per bag, and the plants cost $10 each. She wants to buy at least
5 plants. She cannot spend more than $100. Write and graph a
system of linear inequalities to model all possible solutions to the situation.
Answer: Hi! Read the explanation below:
Brainliest?
Step-by-step explanation:
Let's use the variables x and y to represent the number of bags of soil and plants, respectively, that Katte will buy.
The cost of x bags of soil is $4x, and the cost of y plants is $10y. Therefore, the total cost of Katte's purchases is:
$4x + $10y
We want to make sure that she doesn't spend more than $100, so we can write:
$4x + $10y ≤ $100
We also want to make sure that she buys at least 5 plants, so we can write:
y ≥ 5
Finally, we want to make sure that both x and y are non-negative, since you can't buy negative bags of soil or plants. Therefore, we can write:
x ≥ 0
y ≥ 0
Putting it all together, the system of linear inequalities is:
4x + 10y ≤ 100
y ≥ 5
x ≥ 0
y ≥ 0
To graph this system, we can start by graphing the boundary lines for each inequality. The boundary for 4x + 10y ≤ 100 is the line 4x + 10y = 100, which we can graph by finding two points on the line:
When x = 0, we have 10y = 100, so y = 10. Therefore, one point on the line is (0, 10).
When y = 0, we have 4x = 100, so x = 25. Therefore, another point on the line is (25, 0).
Plotting these two points and connecting them with a line gives us the boundary for 4x + 10y ≤ 100:

The boundary for y ≥ 5 is the horizontal line y = 5. We can graph this line by plotting two points on the line:
When x = 0, we have y = 5, so one point on the line is (0, 5).
When x = 100/4 = 25, we still have y = 5, so another point on the line is (25, 5).
Plotting these two points and connecting them with a line gives us the boundary for y ≥ 5:

When eliminating a loop-carried dependency that adds a constant, the closed-form direct solution will likely contain a multiplication. true or false
The statement "When eliminating a loop-carried dependency that adds a constant, the closed-form direct solution will likely contain a multiplication" is true because eliminating a loop-carried dependency that adds a constant simplifies the equation, but to obtain a closed-form direct solution, we need to express the result as a function of the current iteration's variables only
When eliminating a loop-carried dependency that adds a constant, the closed-form direct solution will likely contain a multiplication. This is because the loop-carried dependency adds a constant to the result of the previous iteration, which means that the current iteration's result is a function of both the current iteration's variables and the previous iteration's result.
By eliminating this dependency, we remove the need to use the previous iteration's result, which simplifies the equation. However, to obtain a closed-form direct solution, we need to express the result as a function of the current iteration's variables only, which often involves a multiplication. This is because multiplication is a fundamental mathematical operation that allows us to combine variables in a way that preserves their individual values.

If cosA = 24/25 tanB = 4/3 and angles A and B are in Quadrant I, find the value of tan(A−B).
If cosA = 24/25 tanB = 4/3 and angles A and B are in Quadrant I. The value of tan(A-B) is -23/33.
What is the value of tan(A-B)?We can start by using the identity: tan(A - B) = (tan A - tan B)/(1 + tan A tan B)
From the given information, we have:
cos A = 24/25, which means sin A = sqrt(1 - cos^2 A) = 7/25 (since A is in Quadrant I)
tan B = 4/3, which means sin B = 4/sqrt(4^2 + 3^2) = 4/5 and cos B = 3/sqrt(4^2 + 3^2) = 3/5
Now, we can use the definitions of sine and cosine to find tan A:
tan A = sin A / cos A = (7/25)/(24/25) = 7/24
Substituting the values we have found into the formula for tan(A - B), we get:
tan(A - B) = (tan A - tan B)/(1 + tan A tan B)
= [(7/24) - (4/3)]/[1 + (7/24)(4/3)]
= (-13/72)/(25/72)
= -13/25
Therefore, tan(A - B) = -13/25.

Here,
Let's say that Plan A's duration is "a" hours and Plan B's duration is "b" hours.
=> Equation 1: 6a + 2b = 10.
=> Equation 2: 3a + 5b = 10.
To get rid of "a," multiply Equation 1 by 3 and Equation 2 by 6 and you get:
=> Equation 3: 18a + 6b = 30
=> Equation 4: 18a + 30b = 60
Equation 3 minus Equation 4 results in:
=> 24b = 30
When we multiply both sides by 24, we get:
=> b=30/24=5/4=1.25 hours.
The value of "b" can now be reinserted into Equation 3 to find "a":
=> 18a + 6(1.25) = 30
=> 18a + 7.5 = 30
=> 18a = 30 - 7.5
=> 18a = 22.5
When we multiply both sides by 18, we get:
=> if a = 22.5/18 then 1.25 hours.

sketch three solutions, with initial values y(0) > 0, y(0) = 0, and y(0) < 0.
To sketch three solutions with initial values y(0) > 0, y(0) = 0, and y(0) < 0, we'll need to use a differential equation or system of differential equations. So, to sketch three solutions with initial values y(0) > 0, y(0) = 0, and y(0) < 0, we would first draw a slope or direction field for our differential equation. Then, we would start at the point (0, y(0)) and follow the direction of the slope or arrow to sketch the solution for each initial value.
To sketch three solutions with the given initial values, follow these steps:
1. Determine the differential equation you're working with. For example, let's consider the equation y'(t) = y(t). This is just an example, and the process will be similar for other differential equations.
2. Solve the differential equation to obtain a general solution. In our example, the general solution is y(t) = C * e^t, where C is an arbitrary constant.
3. Apply the initial values to find specific solutions:
a. For y(0) > 0, choose a positive value for C, such as C = 1. The specific solution is y(t) = e^t.
b. For y(0) = 0, choose C = 0. The specific solution is y(t) = 0.
c. For y(0) < 0, choose a negative value for C, such as C = -1. The specific solution is y(t) = -e^t.
4. Sketch the three solutions on the same graph:
a. For y(t) = e^t, draw a curve that starts at (0,1) and increases exponentially as t increases.
b. For y(t) = 0, draw a horizontal line at y = 0.
c. For y(t) = -e^t, draw a curve that starts at (0,-1) and decreases exponentially (toward 0) as t increases.

Find the exact value of cos J in simplest radical form. I √82 4 J H V98
Answer:
We can start by using the Pythagorean identity to simplify the expression for cos J:
cos^2(J) + sin^2(J) = 1
Since we are given the value of sin J, we can substitute and solve for cos J:
cos^2(J) + (4/√82)^2 = 1
cos^2(J) + 16/82 = 1
cos^2(J) = 66/82
cos(J) = ±√(66/82)
We want to express cos J in simplest radical form, so we can simplify the square root by factoring out the greatest perfect square factor of the numerator:
cos(J) = ±√[(2311)/(2*41)]
cos(J) = ±(√2/2) * (√33/√41)
Since J is in the first or second quadrant (based on the given value of sin J), we know that cos J is positive, so we can drop the negative sign:
cos(J) = (√2/2) * (√33/√41)
Therefore, the exact value of cos J in simplest radical form is (√2/2) * (√33/√41).

O a(z)=2x² + 9x +4
O a(z)=2x² + 5x +4
O a(z)=2-3
O a(z) = 3r+5
The correct function that defines the area of the rectangle is:
A(z) = 2[tex]x^{2}[/tex]+ 9x + 4 (option A).
HOW TO CALCULATE AREA OF THE RECTANGLE?The area of a rectangle is given by the product of its length and width. So, the function that defines the area of the rectangle would be:
A(x) = l(x) * w(x)
where l(x) is the length of the rectangle given by the function 1(x) = 2x + 1, and w(x) is the width of the rectangle given by the function w(x) = x + 4.
Substituting the given functions for length and width, we get:
A(x) = (2x + 1) * (x + 4)
Now, we can expand and simplify the expression:
A(x) = [tex]2x^2 + 8x + x + 4[/tex]
A(x) = [tex]2x^2 + 9x + 4[/tex]

the value of f(6) is -972.To understand why f(6) is equal to -972, we can think of the recursive formula as a process that generates a sequence of numbers. Starting with f(1) = 4, we can apply the formula repeatedly to generate the sequence:
4, -12, 36, -108, 324, -972, ...
How to solve the question?
We can use the recursive formula given to find the value of f(6). Let's start by calculating f(2):
f(2) = -3f(1) = -3(4) = -12
Next, we can calculate f(3) using the same formula:
f(3) = -3f(2) = -3(-12) = 36
We can continue this process for f(4) and f(5):
f(4) = -3f(3) = -3(36) = -108
f(5) = -3f(4) = -3(-108) = 324
Finally, we can use the formula to find f(6):
f(6) = -3f(5) = -3(324) = -972
Therefore, the value of f(6) is -972.
To understand why f(6) is equal to -972, we can think of the recursive formula as a process that generates a sequence of numbers. Starting with f(1) = 4, we can apply the formula repeatedly to generate the sequence:
4, -12, 36, -108, 324, -972, ...
Each term in the sequence is obtained by multiplying the previous term by -3. We can see that the sequence alternates between positive and negative values, with the magnitude of each term growing rapidly. By the time we reach f(6), the magnitude has grown to 972, and the negative sign indicates that the term is negative. Thus, f(6) is equal to -972.

O C. 14
O D. 13
Answer:
The maximum number of data points that may not actually be on the line of best fit for 16 data points is 15 (Option A). This is because a line of best fit is an approximation of the relationship between the variables being studied, and it is unlikely that all data points will fall exactly on the line.
Step-by-step explanation:
To determine the line of best fit, a regression analysis can be performed. This involves finding the equation of the line that best represents the relationship between the variables. The line of best fit minimizes the distance between each data point and the line.
However, even with a perfect line of best fit, there may still be some data points that do not fall exactly on the line. This is due to natural variability in the data and measurement error.
Therefore, it is possible for all 16 data points to fall on the line of best fit, but it is more likely that some points will deviate slightly from the line. The maximum number of data points that may not actually be on the line is 15.
A car uses 1 2/3 gallons of gasoline to travel 50 3/4 how far can the car travel on 1 gallon of gasoline ?
a. 4/125
b. 8/15
c. 36 1/4
d. 71 1/20
The distance that the car travelled on 1 gallon of gasoline is 71 1/20. (option d).
Let's start by finding how far the car can travel on 1/3 gallon of gasoline. We can do this by dividing 50 3/4 by 1 2/3. To divide fractions, we invert the divisor and multiply. So we have:
50 3/4 ÷ 1 2/3 = 50 3/4 × 3/5 = 153/4
This means that the car can travel 153/4 miles on 1 2/3 gallons of gasoline.
Now, we can use the unitary method to find how far the car can travel on 1 gallon of gasoline. We know that the car can travel 153/4 miles on 1 2/3 gallons of gasoline, so we can set up a proportion:
1 2/3 gallons ÷ 153/4 miles = 1 gallon ÷ x miles
To solve for x, we can cross-multiply:
1 2/3 × x = 1 × 153/4
We can simplify the left side by converting 1 2/3 to an improper fraction:
5/3 × x = 153/4
To solve for x, we can cross-multiply again:
5/3x = 153/4 × 3/5
Simplifying both sides, we have:
x = 153/4 × 3/5 ÷ 5/3 = 229/20
So the car can travel 229/20 miles on 1 gallon of gasoline.
To check our answer, we can use the unitary method again to find how far the car can travel on 1 2/3 gallons of gasoline using our answer for how far the car can travel on 1 gallon of gasoline. We have:
1 gallon ÷ 229/20 miles = 1 2/3 gallons ÷ y miles
Simplifying both sides, we have:
20/229y = 3/5
Solving for y, we have:
y = 3/5 × 229/20 ÷ 20/229 = 71 1/20
Therefore, the answer to the question is (d) 71 1/20.

Answer:
D
Step-by-step explanation:
given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
then the x- coordinate of the turning point ( vertex ) is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
y = 2x² + 4x - 3 ← is in standard form
with a = 2, b = 4 , then
[tex]x_{vertex}[/tex] = - [tex]\frac{4}{2(2)}[/tex] = - [tex]\frac{4}{4}[/tex] = - 1
substitute x = - 1 into the equation for corresponding y- coordinate
y = 2(- 1)² + 4(- 1) - 3 = 2(1) - 4 - 3 = 2 - 7 = - 5
turning point = (- 1, - 5 )

The diagonals of quadrilateral ABCD intersect at P. If AB¯¯¯¯¯¯ || CD¯¯¯¯¯¯ and AB¯¯¯¯¯¯ ≅ CD¯¯¯¯¯¯, which additional statement shows that ABCD is a rhombus? A. AP = CP B. BC = AD C. ΔDPA ≅ ΔDPC D. BC¯¯¯¯¯¯ || AD¯¯¯¯¯¯
A rhombus is a quadrilateral with all four sides of equal length. When AB¯¯¯¯¯¯ || CD¯¯¯¯¯¯ and AB¯¯¯¯¯¯ ≅ CD¯¯¯¯¯¯, we know that ABCD is a parallelogram with opposite sides parallel and equal in length. The correct Answer is B.
To show that it is a rhombus, we need to prove that all four sides are equal.
Since the diagonals of a parallelogram bisect each other, we know that AP = CP and BP = DP.
If we can show that BC = AD, we can conclude that ABCD is a rhombus.
Using the fact that AB¯¯¯¯¯¯ || CD¯¯¯¯¯¯, we can show that ΔABP ≅ ΔCDP
Therefore, we have: BP/DP = AB/CD
Hence, the correct answer is B.

to determine the relative effectiveness of different study strategies for the sat, suppose three groups of students are randomly selected: one group took the sat without any prior studying; the second group took the sat after studying on their own from a common study booklet available in the bookstore; and the third group took the sat after completing a paid summer study session from a private test-prep company. the means and standard deviations of the resulting sat scores from this hypothetical study are summarized below: since we are comparing more than 2 groups, we will use anova to test whether the data provide evidence that sat score is related to study strategy. one of the conditions that allows us to use anova safely is that of equal (population) standard deviations. can we assume that this condition is met in this case?
We have to make a suspicion based on the given data. The standard deviations of the three bunches are not given within the address, so we cannot straightforwardly decide whether the condition of equal standard deviations is met. Be that as it may, ready to make a few taught surmises based on what we know almost each gather.
The primary gather, which did not think about, is likely to have a bigger change in scores than the other two bunches since understudies with shifting levels of arrangement and capacity took the test. Subsequently, we might anticipate the standard deviation of this group to be bigger than that of the other two bunches.
It is conceivable that the condition of rise to standard deviations isn't met. In case the condition of equal standard deviations isn't met, we may require to utilize an altered adaptation of ANOVA, such as Welch's ANOVA, which does not expect a rise in changes.

What is graphs?
Graphs are used by mathematicians to logically express or chart facts and values visually. A graph point typically depicts the relationship between several things.
While the cost of feeding an animal may be an important consideration for some people when choosing a pet, it is not necessarily the only or even the most important factor. Many people choose pets based on factors such as their personality, behavior, and the amount of attention and care they require.
Therefore, the animal that is least expensive to feed may not necessarily be the animal that people consider to be their favorite pet.

mark took 30minutes to finish lunch describe the turn the minute hand made
The turn the minute hand made is about 180 degrees when Mark finished his lunch.
How to calculate time with angle?To calculate time with angle, you need to know the angle between the hour hand and the minute hand. With that, you can use the formula
θ = 30H - 11/2M
where H is the current hour and M is the current minute.
Once you calculate the angle, you can use the formula
t = θ/30 to find the elapsed time in hours and decimal fractions of an hour.
The minute hand of a clock makes a full revolution (360 degrees) in 60 minutes (1 hour). Therefore, in 30 minutes, the minute hand will turn half the way around the clock face, which is 180 degrees.

1) Consider the quadratic function: f (x) = (x + 3)2 – 2 and a function, g(x), which is created by translating
f (x) three units to the right, two units up, and reflected vertically over the x-axis. Complete the following tasks:
a) 15 points: Graph f (x) on the axes below and label it. Graph g(x) on the axes below and label it.
b) 10 points: Write the vertex form equation for g(x) below.
The graph of both functions are in the image at the end, and the vertex of g(x) are (0, 0).
How to graph the function g(x)?Here we know that the function f(x) is:
f(x)= (x + 3)² - 2
And g(x) is a translation of 3 units to the right, 2 units up, and reflected over the x-axis, then we have:
g(x) = -[ f(x - 3) + 2]
Replacing f(x) we get:
g(x) = -[ (x + 3 - 3)² -2 + 2]
g(x) = -x²
The graphs of both functions are the ones in the image at the end, there we can see that the vertex of g(x) is (0, 0).
