A local gym instructor has a course load that allows her to teach eight classes. At an interest meeting, 8 people wanted high-­‐
cricket20 [7]

Answer:

<u>The final curse load of the local gym instructor is this:</u>

<u>High-­‐impact aerobics = 1</u>

<u>Low-­‐impact aerobics =  4</u>

<u>Jazzercise = 1</u>

<u>Step exercise = 2</u>

Step-by-step explanation:

1. Let's apportion the class load using the Hamilton method

Number of classes the local gym instructor can teach = 8

Total number of students that want to take a class = 114 (8 people wanted high-­‐impact aerobics, 64 wanted low-­‐impact aerobics, 11 wanted jazzercise, and 31 wanted step exercise)

Standard divisor = 114/8 = 14.25

Now, we can apportion the students in in Standard quotas, this way:

High-­‐impact aerobics = 8/14.25 = 0.5614

Low-­‐impact aerobics = 64/14.25 = 4.49

Jazzercise = 11/14.25 = 0.7719

Step exercise = 31/14.25 = 2.1754

Now, we find the Minimum quota, just considering the whole number and don't taking into account the decimals, this way:

High-­‐impact aerobics = 0

Low-­‐impact aerobics =  4

Jazzercise = 0

Step exercise = 2

As we can see we have 6 classes and there are 2 still pending. Those 2 goes to the classes with the highest decimal portion, in this case, Jazzercise .7719 and High-­‐impact aerobics with .5614.

<u>The final course load is this:</u>

<u>High-­‐impact aerobics = 1</u>

<u>Low-­‐impact aerobics =  4</u>

<u>Jazzercise = 1</u>

<u>Step exercise = 2</u>

H(x)=
UNO [17]

The average rate of change of the function over −2 ≤ x ≤ 2 is 1/2

<h3>How to determine the average rate of change?</h3>

The function is given as:

h(x) = \frac 18x^3 - x^2

The interval is given as:

−2 ≤ x ≤ 2

Calculate h(2) and h(-2)

h(2) = \frac 18 * 2^3 - (2)^2

h(2) = -3

h(-2) = \frac 18 * (-2)^3 - (-2)^2

h(-2) = -5

The average rate of change is then calculated as:

m = \frac{h(-2) - h(2)}{-2-2}

This gives

m = \frac{-5 + 3}{-4}

Evaluate

m = 1/2

Hence, the average rate of change of the function over −2 ≤ x ≤ 2 is 1/2

Alenkinab [10]

Answer:

<h2>301.593</h2><h2></h2>

Step-by-step explanation:

surface area of a cylinder = 2πrh + 2πr²

where: r = 4 km radius

           h = 8 km

plugin values into the formula

surface area of a cylinder = 2πrh + 2πr²

                                          = 2 π (4) 8  + 2 π (4)²

                                          = 201.062 + 100.531

                                          = 301.593 km²

The real number part of the complex numbers -5+3i
Alisiya [41]

Answer:

Real part = -5

Step-by-step explanation:

The real part of a complex number of the form a+bi, is that which doesn't have the "i" (imaginary unit) factor. therefore the real part is "a"

In this case (-5+3i) the real part is -5.
