Problem 1

We'll use the product rule to say

h(x) = f(x)*g(x)

h ' (x) = f ' (x)*g(x) + f(x)*g ' (x)

Then plug in x = 2 and use the table to fill in the rest

h ' (x) = f ' (x)*g(x) + f(x)*g ' (x)

h ' (2) = f ' (2)*g(2) + f(2)*g ' (2)

h ' (2) = 2*3 + 2*4

h ' (2) = 6 + 8

h ' (2) = 14

<h3>Answer: 14</h3>

============================================================

Problem 2

Now we'll use the quotient rule

h(x) = \frac{f(x)}{g(x)}\\\\h'(x) = \frac{f'(x)*g(x)-f(x)*g'(x)}{(g(x))^2}\\\\h'(2) = \frac{f'(2)*g(2)-f(2)*g'(2)}{(g(2))^2}\\\\h'(2) = \frac{2*3-2*4}{(3)^2}\\\\h'(2) = \frac{6-8}{9}\\\\h'(2) = -\frac{2}{9}\\\\

<h3>Answer:  -2/9</h3>

============================================================

Problem 3

Use the chain rule

h(x) = f(g(x))\\\\h'(x) = f'(g(x))*g'(x)\\\\h'(2) = f'(g(2))*g'(2)\\\\h'(2) = f'(3)*g'(2)\\\\h'(2) = 3*4\\\\h'(2) = 12\\\\

<h3>Answer:  12</h3>

Riley was determined to be on the basketball team. He started practicing for 40 minutes on the first day, and then increased his
Alexeev081 [22]

Answer:

With Riley's pattern, he will practice 2,000 total minutes in 25 days.

Step-by-step explanation:

Since Riley increased his practice time by 20, 20 times 40 is 80 minutes. And since he is repeating this in total of 25 days, 80 times 25 is 2,000.

Hope this helped you in some way. If not, then let me know.

The circumference of a circle is 47.1 and the diameter of the circle is 15. Which best represents
kvv77 [185]

Answer: \pi =\frac{47.1}{15}

Step-by-step explanation:

The complete exercise is: "The circumference of a circle is 47.1 and the diameter of the circle is 15. Which best represents the value of π? "

In order to solve this exercise, it is important to remember that the circle can be calculated with the following formulas:

1. C=\pi D

Where "C" is the circumference of the circle and "D" is the diameter of the circle.

2. C=2\pi r

Where "C"  is the circumference of the circle and "r" is the radius of the circle (Remeber that the diameter is twice the radius).

In this case, the exercise gives you the circumference of the circle and its diameter. These are:

C=47.1\\\\d=15

Then, knowing those values, you can substitute them s into the first equation  C=\pi D, as following:

47.1=\pi (15)

The final step is to solve for \pi:

\pi =\frac{47.1}{15}
