The two functions f(x) and g(x) are f(x) = √x and g(x) = x - 3

From the question, we have the following parameters that can be used in our computation:

h(x) = sqrt(x - 3)

(f ∘ g)(x) = h(x)

This means that

(f ∘ g)(x) = sqrt(x - 3)

Rewrite the above equation properly

So, we have the following representation

(f ∘ g)(x) = √(x - 3)

The function (f ∘ g)(x) is calculated as

(f ∘ g)(x) = f(g(x))

So, we have

f(g(x)) = √(x - 3)

This means that

f(g(x)) = √g(x)

By comparison. we have

g(x) = x - 3

f(x) = √x

Hence, the functions are f(x) = √x and g(x) = x - 3

John will earn an annual interest of $500 on a beginning balance of $10,000 at a rate of 5% per year. After one year, the ending balance will be $10,500. John earned $160 in interest after leaving his initial deposit of $8,000 in the bank for first year with annual compounding at a 2% interest rate. His ending balance was $8,160. The table shows his ending balance for years 5-10.

Here, we have,

We can use the formula for simple interest to calculate the annual interest earned by John on a balance of $10,000 at a rate of 5% per year

Annual interest = (Principal x Rate x Time) / 100

where Principal is the beginning balance, Rate is the interest rate, and Time is the duration of investment in years.

Substituting the given values, we get

Annual interest = (10000 x 5 x 1) / 100 = $500

Therefore, the annual interest earned by John on a balance of $10,000 at a rate of 5% per year is $500.

Ending balance after one year = Beginning balance + Annual interest = $10,000 + $500 = $10,500.

since the term of the annual CD is four years, and John will leave his money in the bank for four years, we can calculate the ending balance at the end of each year using the formula above.

For year 5

P = $8,160

r = 0.02

n = 1

t = 1

A = $8,160 (1 + 0.02/1)^(1x1) = $8,324.80

For year 6

P = $8,324.80

r = 0.02

n = 1

t = 1

A = $8,324.80 (1 + 0.02/1)^(1x1) = $8,492.78

For year 7

P = $8,492.78

r = 0.02

n = 1

t = 1

A = $8,492.78 (1 + 0.02/1)^(1x1) = $8,664.28

For year 8

P = $8,664.28

r = 0.02

n = 1

t = 1

A = $8,664.28 (1 + 0.02/1)^(1x1) = $8,839.44

For year 9

P = $8,839.44

r = 0.02

n = 1

t = 1

A = $8,839.44 (1 + 0.02/1)^(1x1) = $9,018.34

For year 10

P = $9,018.34

r = 0.02

n = 1

t = 1

A = $9,018.34 (1 + 0.02/1)^(1x1) = $9,201.05

Answer:

y is 96 when x is 12

Step-by-step explanation:

If x and y vary directly, it means that they are proportional to each other. Mathematically, we can write this relationship as:

y = kx

where k is the constant of proportionality.To find the value of k, we can use the information given in the problem. We know that when x is 6, y is 48. Substituting these values in the equation above, we get:

48 = k * 6

Solving for k, we get:k = 8

Now that we know the value of k, we can use the equation to find y when x is 12:

y = kx

y = 8 * 12

y = 96

Therefore, when x is 12, y is 96.

also in my head I just said if 12 is double of 6, just double 48, which is 96. but that doesn’t always work so that’s why I provided “correct” work above

The estimated time required for the production of the eleventh 787 jet is approximately 14,580 hours.

To calculate this, we start with the given information that it takes Boeing 29,454 hours to produce the fifth 787 jet. The learning factor of 75% indicates that there is an expected reduction in production time as workers become more experienced and efficient. This means that each subsequent jet is expected to take less time to produce compared to the previous one.

To determine the time required for the eleventh 787, we apply the learning factor to the time taken for the fifth jet. We multiply 29,454 hours by the learning factor of 0.75 to obtain 22,090.5 hours. Since we are asked to round the response to the nearest whole number, the estimated time for the eleventh 787 is approximately 22,091 hours.

However, we are specifically asked for the time required for the eleventh unit, which implies that the learning factor is not applied to subsequent units beyond the fifth jet. Therefore, we can directly divide the estimated time for the fifth jet, which is 29,454 hours, by the number of units (11) to calculate the time required for the eleventh 787. This gives us an estimated production time of approximately 14,580 hours.

The cosine law is used to determine the angle between two sides of a triangle. The measure of ∠Z to the nearest degree is -120°.

The cosine law for a triangle is derived from the parallelogram law of addition for two vectors.

It is given as for a triangle having sides a, b and c, the cos of the angle between sides a and b is given by,

cos(x) = (a^(2) + b^(2) - c^(2)) / (2 × a × b).

The diagram for the given ΔXYZ is given below,

Given that,

x = 5.2 inches, y = 9.8 inches and z = 7.1 inches.

In order to find ∠Z, apply cosine law for the given triangle as,

cos(Z) = (x^(2) + z^(2) - y^(2)) / (2 × x × z)

Substitute the given values to get,

cos(Z) =  (5.2)^(2) + (7.1)^(2) - (9.8)^(2)) / (2 × 5.2 × 7.1)

=> cos(Z) = -18.59 / 73.84

=> cos(Z) = -0.251

=>∠Z = 104.5° (approximately).

Hence, the value of ∠Z is 104.5° to the nearest degree.

The magnitude of the vertical force applied to the horizontal leg in the equivalent force system.

To determine the magnitude of the vertical force applied to the horizontal leg, we need to find the vertical component of the given force system. Looking at the diagram, we observe that the force system consists of a vertical force at point A and a horizontal force at point B. We can use trigonometry to find the vertical component of the force at point A.

Let's denote the magnitude of the force at point A as F_A and the angle it makes with the horizontal leg as θ. The vertical component of the force can be calculated using the formula: Vertical component = F_A * sin(θ).

Since the vertical component of the force should be equal to the force we are trying to find, we can set up the equation: Vertical component = F_vertical.

Now, we can substitute the given values into the equation and solve for F_vertical. Once we have the value, we can round it off to the nearest whole number, as instructed.

Sample mean = 61.57 (rounded to 2 decimal places). Sample standard deviation = 9.98 (rounded to 2 decimal places)

(a) To calculate the sample mean, we need to add up all the data points and divide by the number of observations.
Sum of all the data = 83 + 46 + 61 + 40 + 83 + 67 + 45 + 66 + 70 + 69 + 80 + 58 + 68 + 60 + 67 + 72 + 73 + 70 + 57 + 63 + 70 + 78 + 52 + 67 + 53 + 67 + 75 + 61 + 70 + 81 + 76 + 79 + 75 + 76 + 58 + 31
Count of observations = 35
Sample mean = Sum of all the data / Count of observations
Sample mean = (result of the sum of all the data) / 35
To calculate the sample standard deviation, we need to find the difference between each data point and the mean, square the differences, sum them up, divide by the number of observations minus 1, and then take the square root of the result.
Step 1: Find the difference between each data point and the mean.
Step 2: Square the differences.
Step 3: Sum up the squared differences.
Step 4: Divide the sum by the count of observations m

Step 5: Take the square root of the result.

Sample mean = 61.57 (rounded to 2 decimal places)

Sample standard deviation = 9.98 (rounded to 2 decimal places)

(b) To calculate the sample mean and sample standard deviation after removing the smallest observation (31°F), we repeat the same steps as in part (a), but now using the remaining data points.
First, remove 31°F from the data set.
Next, calculate the sample mean and sample standard deviation using the remaining data points.

A- The average rate of change of g(x) over the interval [-2, 2] is 4, B- the instantaneous rates of change at the endpoints are different from the average rate of change over the interval.

A) To find the average rate of change of the function g(x) over the interval [-2, 2], we need to compute the difference quotient:

average rate of change = [g(2) - g(-2)] / [2 - (-2)]

First, we find the values of the function at the endpoints of the interval:

g(-2) = \(-2^{3}\) - 6 = -14

g(2) = \(2^{3}\) - 6 = 2

Substituting these values into the

average rate of change = (2 - (-14)) / (2 - (-2)) = 16 / 4 = 4

Therefore, the average rate of change of g(x) over the interval [-2, 2] is 4.

B) To compare this rate with the instantaneous rates of change at the endpoints of the interval, we need to find the derivatives of the function at x=-2 and x=2 using the power rule of differentiation:

g'(x) = 3\(x^{2}\)

g'(-2) = 3\(-2^{2}\) = 12

g'(2)  = 12

The instantaneous rate of change at x=-2 is 12, and the instantaneous rate of change at x=2 is also 12. These values are equal to the average rate of change over the interval [-2, 2], which is 4.

This means that the function g(x) is not a linear function over the interval [-2, 2], and the instantaneous rates of change at the endpoints are different from the average rate of change over the interval.

The cofunction identity for sec(90° - A) is sec(90° - A) = c * cos(90° - A) / b using the definitions of the trigonometric ratios for a right triangle

To derive the cofunction identity for sec(90° - A) using the definitions of the trigonometric ratios for a right triangle, we can start by considering a right triangle with an angle A. Let's denote the sides of the triangle as follows:

Opposite side to angle A: a

Adjacent side to angle A: b

Hypotenuse: c

Using the definitions of the trigonometric ratios, we have:

sin(A) = a/c

cos(A) = b/c

tan(A) = a/b

Now, let's consider the angle (90° - A). In this case, the sides of the triangle change as follows:

Opposite side to angle (90° - A): b

Adjacent side to angle (90° - A): a

Using the definitions of the trigonometric ratios, we have:

sin(90° - A) = b/c

cos(90° - A) = a/c

tan(90° - A) = b/a

We can rearrange the equation cos(90° - A) = a/c to solve for a:

a = c * cos(90° - A)

Now, let's substitute this expression for a in the equation tan(90° - A) = b/a:

tan(90° - A) = b / (c * cos(90° - A))

Recall that sec(A) is the reciprocal of cos(A). Applying this to the equation, we get:

sec(90° - A) = 1 / cos(90° - A) = 1 / (b / (c * cos(90° - A)))

Simplifying further:

sec(90° - A) = c * cos(90° - A) / b
