Answer:

y = (3/2)x + 17/2

Slope: 3/2

Step-by-step explanation:

y + 2 = 3/2 (x+7)

y + 2 = (3/2)x + 21/2

y = (3/2)x + 21/2 - 2

y = (3/2)x + 21/2 - 4/2

y = (3/2)x +17/2

The approximate time, compass heading, distance, and fuel consumed during the climb of the airplane are 18 minutes, 214°, 2,430 nautical miles, and 3.9 gallons, respectively.

To determine the approximate time, compass heading, distance, and fuel consumed during the climb of the airplane, we need to use some basic principles of navigation and aviation.

First, we need to calculate the climb time. Since the airplane is climbing at a rate of 500 ft/min and the cruise altitude is 9,500 ft, the time it takes to climb to the cruise altitude can be calculated as (9,500-1,000)/500 = 18 minutes.

To calculate the compass heading, we need to account for the variation and deviation. The true course is given as 215°, and the variation is 3° W, which means we need to subtract 3° from the true course to get the magnetic course.

Therefore, the magnetic course is 215° - 3° = 212°. Next, we need to account for the deviation, which is given as -2°, meaning we need to add 2° to the magnetic course to get the compass heading. Therefore, the compass heading is 212° + 2° = 214°.

The distance traveled during the climb can be calculated using the average true airspeed and the climb time. The distance is given by the formula: distance = airspeed x time. Therefore, the distance traveled during the climb is approximately 135 kts x 18 min = 2,430 nautical miles.

Finally, we can calculate the fuel consumed during the climb using the average fuel consumption rate. The fuel consumed is given by the formula: fuel consumed = fuel consumption rate x time. Therefore, the fuel consumed during the climb is approximately 13 gal/hr x 18 min/60 min = 3.9 gallons.

The trigonometric identity has been proven as 1 in the space below

Given the identity:

tan(1/2x) (2cot(x) + tan(1/2x)) = 1

To prove this identity, let's start by expressing cot(x) in terms of tan(x):

cot(x) = 1 / tan(x)

Now, replace cot(x) in the given identity:

tan(1/2x) (2(1/tan(x)) + tan(1/2x)) = 1

Now, let's use the double angle formula for tan(x):

tan(x) = 2 * tan(1/2x) / (1 - tan^2(1/2x))

Replace tan(x) in the equation:

tan(1/2x) (2(1/(2 * tan(1/2x) / (1 - tan^2(1/2x))) + tan(1/2x)) = 1

Simplify the equation:

tan(1/2x) ((1 - tan^2(1/2x)) + tan(1/2x) * tan(1/2x)) = 1

Now, notice that the expression in the parentheses is equal to 1:

(1 - tan^2(1/2x)) + tan^2(1/2x) = 1

So, we can simplify the equation further:

tan(1/2x) * 1 = 1

Answer:

The equation x - y = 7 represents a linear equation with two variables, x and y. To find three ordered pairs (x, y) that satisfy this equation, we can arbitrarily choose values for one variable and solve for the other.

Ordered Pair 1:

Let's choose x = 0:

x - y = 7

0 - y = 7 (Substituting x = 0)

y = -7

So, the first ordered pair is (0, -7).

Ordered Pair 2:

Let's choose y = 0:

x - y = 7

x - 0 = 7 (Substituting y = 0)

x = 7

So, the second ordered pair is (7, 0).

Ordered Pair 3:

Let's choose x = 5:

x - y = 7

5 - y = 7 (Substituting x = 5)

y = -2

So, the third ordered pair is (5, -2).

Therefore, three ordered pairs (x, y) that satisfy the equation x - y = 7 are: (0, -7), (7, 0), and (5, -2).

I will be finding the minimum of this parabolic function.

The function y = x^2 - 9 is a parabola that opens upwards, since the coefficient of the x^2 term is positive. Therefore, the minimum value of the function occurs at the vertex of the parabola.

To find the x-coordinate of the vertex, we can use the formula -b/2a, where the quadratic function is in the form y = ax^2 + bx + c. In this case, a = 1 and b = 0, so the x-coordinate of the vertex is -b/2a = -0/(2*1) = 0.

To find the corresponding y-coordinate of the vertex, we can substitute x = 0 into the function, which gives y = 0^2 - 9 = -9.

Therefore, the minimum value of the function y = x^2 - 9 is -9, which occurs at x = 0.

The minimum point of this function is located at (0, -9).

So from plain sight we can tell we're looking for a maximum point, because the coefficient of x² is positive, it's 1. If the function was y=-x²-9, we would be looking at a minimum point.

The vertex if the exact point where a quadratic or any pair exponent function will start to either decay or increase, therefore, it will be the minimum or maximum point.

Formula for "x" value of vertex: [tex]\sf x_{Vertex} =\dfrac{-b}{2a}[/tex].

In this equation, a and b are coefficients extracted when the formula is expressed on its standard form.

Standard form of a quadratic equation: ax² + bx + c = 0

➔ You need to substitute the "y" by a "0", and the formula should look like this:

[tex]\sf 0=x^2-9[/tex]

➔ Reorganizing...

[tex]\sf x^2-9=0[/tex]

Let's expand the previous expression:

[tex]\sf x^2+0x_{} -9=0[/tex]

The coefficients are:

a= 1, beacuse "x²" is being multiplied by 1, which is implicit.

b= 0, because "x" doesn't really exist on the simplified equation.

c= -9.

Now let's calculate the "x" position of the vertex using the formula from step 2:

[tex]\sf x_{Vertex} =\dfrac{-b}{2a}=\dfrac{-(0)}{2(1)}=0[/tex]

Now, the "y" value can be obtained just by substituting "x" by 0 on the argument of the function:

[tex]\sf y=(0)^2-9\\ \\y=-9[/tex]

Therefore, the vertex, or minimum point of this function is located at (0, -9).

Answer: This problem involves finding the number of non-negative integer solutions to the equation x₁ + x₂ + x3 + x₁ = 20 subject to the given constraints. We can use the stars and bars method to solve this problem.

Suppose we have 20 stars representing the sum x₁ + x₂ + x3 + x₁. To separate these stars into four groups corresponding to x₁, x₂, x₃, and x₄, we need to place three bars. For example, if we have 20 stars and 3 bars arranged as follows:

**|**||

then the corresponding values of x₁, x₂, x₃, and x₄ are 2, 4, 6, and 8, respectively. Notice that the position of the bars determines the values of x₁, x₂, x₃, and x₄.

In general, the number of ways to place k identical objects (stars) into n distinct groups (corresponding to x₁, x₂, ..., xₙ-₁) using n-1 separators (bars) is given by the binomial coefficient (k+n-1) choose (n-1), which is denoted by C(k+n-1, n-1).

Thus, the number of non-negative integer solutions to the equation x₁ + x₂ + x3 + x₁ = 20 subject to the given constraints is:

C(20+4-1, 4-1) = C(23, 3) = 1771

However, this count includes solutions that violate the upper bounds on x₁, x₂, x₃, and x₄. To eliminate these solutions, we need to use the principle of inclusion-exclusion.

Let Aᵢ be the set of non-negative integer solutions to the equation x₁ + x₂ + x3 + x₁ = 20 subject to the given constraints, where xᵢ ≥ mᵢ for some integer mᵢ. Then, we want to find the cardinality of the set:

A = A₀ ∩ A₁ ∩ A₂ ∩ A₃

where A₀ is the set of all non-negative integer solutions to the equation x₁ + x₂ + x3 + x₁ = 20, and Aᵢ is the set of solutions that violate the upper bound on xᵢ.

To find the cardinality of A₀, we use the formula above and obtain:

C(20+4-1, 4-1) = 1771

To find the cardinality of Aᵢ, we subtract the number of solutions that violate the upper bound on xᵢ from the total count. For example, to find the cardinality of A₁, we subtract the number of solutions where x₂ ≥ 4 from the total count. To count the number of solutions where x₂ ≥ 4, we fix x₂ = 4 and then count the number of solutions to the equation x₁ + 4 + x₃ + x₄ = 20 subject to the constraints 0 ≤ x₁ < 3, 0 ≤ x₃ < 5, and 0 ≤ x₄ < 6. This count is given by:

C(20-4+3-1, 3-1) = C(18, 2) = 153

Similarly, we can find the cardinalities of A₂ and A₃ by fixing x₃ = 5 and x₄ = 6, respectively. Using the principle of inclusion-exclusion, we obtain:

|A| = |A₀| - |A

we should expect 4 of the next 20 pastries served to be bran muffins.

How to solve the question?

To calculate the expected number of bran muffins out of the next 20 pastries served, we need to first determine the proportion of pastries that are bran muffins out of the total number of pastries observed.

The total number of pastries observed is 10 (1 poppy seed muffin + 3 cinnamon rolls + 2 bran muffins + 2 apple fritters + 2 croissants). Out of these, 2 are bran muffins. Therefore, the proportion of pastries that are bran muffins is 2/10 or 0.2.

To calculate the expected number of bran muffins out of the next 20 pastries served, we simply multiply the proportion of bran muffins by 20.

Expected number of bran muffins = 0.2 x 20 = 4

Therefore, we should expect 4 of the next 20 pastries served to be bran muffins.

It's important to note that this calculation assumes that the proportion of bran muffins served remains the same for the next 20 pastries. If there are any changes in the pastry selection or the proportion of each pastry, the expected number of bran muffins would also change.

The correct answer is an option (A) 144.5 pounds per year, which is the closest value to the calculated average yearly growth rate of the elephant.

The term "average" refers to a measure of central tendency that represents the typical or typical value in a set of data.

Growth rate refers to the rate at which a quantity or value increases or decreases over time. It is often expressed as a percentage or a proportion and is used to measure the change in a particular variable relative to its initial value.

According to the given information:

To find the average yearly growth rate of the elephant, we can use the formula for calculating growth rate:

Growth Rate = ((Ending Value - Starting Value) / Number of Years)

In this case, the starting weight of the elephant is 220 pounds and the ending weight is 870.25 pounds. The number of years is 4.5 (since the growth occurred over 4.5 years).

Plugging these values into the formula, we get:

Growth Rate = ((870.25 - 220) / 4.5)

Simplifying the numerator, we get:

Growth Rate = 650.25 / 4.5

Dividing, we get:

Growth Rate ≈ 144.50 pounds per year

Answer:

To approximate the positive zero of the given polynomial function f(x), we can use numerical methods such as the Newton-Raphson method or the bisection method. Here, we will use the latter method.

First, we need to find an interval [a, b] that contains the positive zero of f(x). We can do this by observing the behavior of the function near the origin and near large positive values of x. We can see that f(0) = -1 is negative and that f(x) becomes more and more negative as x approaches infinity. This suggests that the positive zero of f(x) is somewhere in the interval (0, infinity).

We can evaluate f(x) at x = 1 and x = 2 to determine which half of the interval contains the positive zero. We have:

f(1) = 2(1)² - 1 - 16(1)³ - 3(1)² - 8(1) - 2 = -24

f(2) = 2(2)² - 1 - 16(2)³ - 3(2)² - 8(2) - 2 = -207

Since f(1) is negative and f(2) is very negative, we can conclude that the positive zero of f(x) is in the interval (1, 2).

Next, we can use the bisection method to refine the interval and approximate the positive zero to two decimal places. We start by evaluating f(c), where c is the midpoint of the interval (1, 2):

c = (1 + 2)/2 = 1.5

f(c) = 2(1.5)² - 1 - 16(1.5)³ - 3(1.5)² - 8(1.5) - 2 ≈ -97.875

Since f(c) is negative, the positive zero of f(x) must be in the interval (c, 2). We can repeat the process by finding the midpoint of this interval:

c = (1.5 + 2)/2 = 1.75

f(c) = 2(1.75)² - 1 - 16(1.75)³ - 3(1.75)² - 8(1.75) - 2 ≈ -38.104

Again, f(c) is negative, so the positive zero of f(x) must be in the interval (c, 2). We can repeat the process until the interval is small enough to obtain the desired level of accuracy.

Using a calculator or a computer program, we can continue the bisection method and find that the positive zero of f(x) is approximately 1.49, rounded to two decimal places.

Distance is a scalar quantity that refers to the total length traveled by an object or person, without considering the direction. It is a measure of the path length between two points, usually measured in units such as meters (m), feet (ft), or kilometers (km).

In the given question,

The formula t = √(d/16) relates the time t (in seconds) it takes an object to fall a distance d (in feet) to the acceleration due to gravity, which is approximately 32.2 feet per second squared.

To find how far the object will fall in 8 seconds, we can rearrange the formula to solve for d:

t = √(d/16)

t² = d/16 (Squaring both sides)

d = 16t² (Multiplying both sides by 16)

Substituting t = 8 into the formula, we get:

d = 16(8)² = 1024

Therefore, the object will fall a distance of 1024 feet in 8 seconds.

So the answer is (C) 1024 ft.

The equation of circle in the standard with given center and radius is  [tex](x+3)^{2} + (y-4)^2[/tex] = 49.

What is equation of circle?

Every point in a plane that is at a certain distance from the center point forms a circle. In order to go around a curve while maintaining a constant distance from another point, a moving point in a plane must follow a specific path.

The following is the typical form for expressing the equation of a circle:

[tex](x-h)^{2} + (y-k)^2 = r^2[/tex]

Here,

(h, k) represents the center and r is the radius.

We are given that the center is (-3, 4) and the radius is 7.

Now, using the standard form, we get

⇒ [tex](x-(-3))^{2} + (y-4)^2 = 7^2[/tex]

⇒ [tex](x+3)^{2} + (y-4)^2[/tex] = 49

Hence, the equation of circle in the standard with given center and radius is  [tex](x+3)^{2} + (y-4)^2[/tex] = 49.
