If Mariana needs to surround the garden with a stone-path, then she would need 20 feet of stone, Option (d) is correct.

The "Perimeter" of a rectangle is defined as the "total-length" of the outer boundary.

The length of the rectangle can be calculated as the difference between the x-coordinates of the vertices on the same vertical side.

In this case, the "x-coordinates" of vertices on same vertical side are 4 and -2.

So, the length of the rectangle is = 4 -(-2) = 6 feet.

Similarly, the width of rectangle is calculated as difference between "y-coordinates" of vertices on same horizontal side.

In this case, the "y-coordinates" of vertices on same horizontal side are 1 and -3.

So, the width of the rectangle is = 1 -(-3) = 4 feet,

To surround rectangle with a stone path, Marina need to add length of stone needed for the perimeter of rectangle, which is sum of all four sides.

The perimeter (P) is ⇒ P = 2(length + width),

Substituting the values,

We get,

⇒ P = 2(6 + 4) = 2(10) = 20 feet

The value of x is 65. Please note that this solution is based on the assumption that the angles QRP and PSQ are supplementary. If this assumption doesn't hold, feel free to let me know.

We need to find the value of x in the equation ZQRP = (2x + 20)° given that ZPSQ = 30°. Since the question doesn't provide enough information about the relationship between angles QRP and PSQ, I'll assume that they are supplementary angles (angles that add up to 180°). This assumption is based on the possibility that the angles form a straight line or a linear pair.

If angles QRP and PSQ are supplementary, their sum is 180°:

(2x + 20)° + 30° = 180°

Now, we can solve for x:

2x + 50 = 180

Subtract 50 from both sides:

2x = 130

Divide by 2:

x = 65

Step-by-step explanation: Gas mileage refers to the quantity of miles driven per unit volume of gasoline, typically expressed as "miles per gallon." In the context of the present inquiry, the vehicle in question exhibited a capacity to traverse a distance of 310 miles subsequent to the utilization of 20 gallons of gasoline. Thus, it is possible to calculate the gas mileage through the division of the quantity of gas consumed by the distance elapsed, resulting in:

The fuel efficiency of a vehicle, represented by the metric of gas mileage, is typically calculated by the ratio of distance traveled in miles to the amount of fuel consumed in gallons. In the present case, the gas mileage is equivalent to the quotient of 310 miles by 20 gallons, resulting in an efficiency rating of 15.5 miles per gallon.

Step-by-step explanation:

Because same numbers = same y intercept but I'm not sure

Answer:

  1) The image has the same slope, different y-intercept

Step-by-step explanation:

You want the relationship between the line 3x -5y = 4 and its image dilated by a factor of 5/3 centered at the origin.

Dilation about the origin multiplies every coordinate by the dilation factor. Dilation does not change slopes or angles, but it changes lengths by the dilation factor.

When the equation of a line is written in standard form, the dilation of it effectively multiplies the constant by the dilation factor.

The given line has intercepts ...

  ax +by = c

  x-intercept = c/a = 4/3

  y-intercept = c/b = -4/5

If these values are multiplied by the dilation factor 5/3, they become ...

  x-intercept' = (5/3)(4/3) = 20/9 = 2 2/9

  y-intercept' = (5/3)(-4/5) = -4/3 . . . . . note the y-intercept has changed

The slope of the given line can be determined from its intercepts:

  m = (-y intercept)/(x intercept) = -(-4/5)/(4/3) = 3/5

Since both of these intercepts are multiplied by the same dilation factor, their ratio remains unchanged. The slope of the dilated line is the same.

Effectively, the dilated line's equation is ...

  3x -5y = 4(5/3)

  3x -5y = 20/3

In mathematics, an inequality is a mathematical statement that describes a relationship between two quantities that are not necessarily equal. An inequality can express that one quantity is less than, less than or equal to, greater than, greater than or equal to, or not equal to another quantity.

Inequalities can be represented using various symbols. For example, the symbol < represents "less than," the symbol > represents "greater than," the symbol ≤ represents "less than or equal to," and the symbol ≥ represents "greater than or equal to." The symbol ≠ represents "not equal to."

Inequalities are also used in algebra to solve equations and to represent the solution set of an equation. In this context, an inequality can represent all the possible values of a variable that satisfy the equation. For example, the inequality x > 5 represents all the values of x that make the expression x - 5 positive.

We can write an inequality to represent the number of points, m, obtained by Machelle on her exam:

m > 100 - 27

the probability that no two people of the same sex sit next to each other is 2/7.

One way to solve this problem is to use the principle of inclusion-exclusion. Let A be the event that the boys sit next to each other, and let B be the event that the girls sit next to each other. Then, we want to find the probability of the complement of (A or B), which is the probability that neither A nor B occurs.

The probability of A occurring is the same as the probability of the 5 boys sitting in a row, which is 5! (since each order is equally likely). Similarly, the probability of B occurring is 5!. However, we need to subtract the probability of A and B occurring simultaneously. This can be seen as follows: once the boys are seated in a row, there are 6 spaces (between or on the ends) where the girls can be seated. Thus, the probability of A and B occurring is 2*5!*6.

Therefore, the probability of neither A nor B occurring (i.e., the probability that no two people of the same sex sit next to each other) is:

P(neither A nor B) = 1 - P(A or B) = 1 - [P(A) + P(B) - P(A and B)]

= 1 - [(25!) / 10! - (25!6) / 10!]

The values of x for which the function f(x) = x³ + 3x² - 9x + 7 is increasing are (-∞, -3) and (1, +∞).

To find the values of x for which the function f(x) = x³ + 3x² - 9x + 7 is increasing, we need to take the derivative of the function and determine where the derivative is positive.

f(x) = x³ + 3x² - 9x + 7

f'(x) = 3x² + 6x - 9

To find where f(x) is increasing, we need to find the values of x where f'(x) > 0.

3x² + 6x - 9 > 0

Simplifying this inequality, we get

x² + 2x - 3 > 0

Factoring the left side of the inequality, we get

(x + 3)(x - 1) > 0

The critical points of f(x) occur when f'(x) = 0 or when the denominator of f'(x) is undefined. The denominator of f'(x) is always defined, so we only need to find where f'(x) = 0

3x² + 6x - 9 = 0

Dividing both sides by 3, we get

x² + 2x - 3 = 0

Factoring the left side of the equation, we get

(x + 3)(x - 1) = 0

So the critical points of f(x) are x = -3 and x = 1.

Carly will need to buy 27.05 gallons of gas for the trip, which will cost her $7.28.

To calculate the total cost of the road trip, we need to find out how many gallons of gas Carly will need and then multiply that by the cost per gallon.

First, we need to convert the distance from miles to gallons, using the truck's fuel efficiency of 21 miles per gallon

568 miles ÷ 21 miles per gallon = 27.05 gallons

So Carly will need approximately 27.05 gallons of gas for the trip.

Next, we need to convert the cost of gas from liters to gallons. There are 3.79 liters in 1 gallon, so the cost of gas is:

$1.02 per liter ÷ 3.79 liters per gallon = $0.269 per gallon

Finally, we can calculate the total cost of the road trip by multiplying the number of gallons of gas by the cost per gallon

27.05 gallons × $0.269 per gallon = $7.28

Therefore, the road trip will cost Carly approximately $7.28.

Answer:

To complete each statement, we will need to perform some operations on the given complex numbers w and z.

1. Find w^3:

We can use De Moivre's theorem to raise w to the third power:

w^3 = [2(cos(90°) + i sin(90°))]^3

= 2^3(cos(90°3) + i sin(90°3))

= 8(cos(270°) + i sin(270°))

Therefore, w^3 = 8(cos(270°) + i sin(270°)).

2. Simplify z^2:

To simplify z^2, we can use the identity cos(2θ) = 2cos^2(θ) - 1 to simplify the cosine term:

z^2 = [√(cos(250°) + i sin(225°))]^2

= cos(2250°) + i sin(2225°)

= cos(500°) + i sin(450°)

= cos(140°) - i sin(90°)

Therefore, z^2 = cos(140°) - i sin(90°).

Note: We can also simplify the square root of the cosine term using the identity cos(2θ) = 1 - 2sin^2(θ), but this would result in a more complicated expression for z^2.

3. Find the product wz:

We can simply multiply w and z using the distributive property:

wz = 2(cos(90°) + i sin(90°)) * √(cos(250°) + i sin(225°))

= 2√(cos(90°)cos(250°) - sin(90°)sin(250°) + i(cos(90°)sin(250°) + sin(90°)cos(250°)))

= 2√(-sin(250°) + i cos(250°))

Therefore, wz = 2√(-sin(250°) + i cos(250°)).
