Answer: d ≈ 5.73 ft

Step-by-step explanation: Using the formulas

                                             C=2πr

                                             d=2r

                                             Solving for d

                                             d= C/π = 18/π ≈ 5.72958ft

Answer:

5.732484076 =d

Step-by-step explanation:

The circumference is given by

C = pi*d

18 = 3.14 *d

Divide each side by 3.14

18/3.14 = 3.14d/3.14

5.732484076 =d

Find the critical numbers of the function. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE
Furkat [3]

Answer:

x = -6 and x = 4

Step-by-step explanation:

In math, the critical points of a function are the points where the derivative equals zero.

So, first we will find the derivative of the function. The derivative is:

f'(x)=3x^2 +6x-72

Now, we are going to make the derivative equal zero and find the answers of the equation.

3x^2 +6x-72=0\\3(x^2 +2x-24)=0\\3(x+6)(x-4)=0\\

So we have that the critical points are the answers to this equation:

x+6= 0 \\x= - 6

and

x-4=0\\x=4

Thus, the critical points are x=-6 and x=4

mojhsa [17]

11.25 - 10.5 = 0.75

Knowing that this is the profit she makes with one share, so:

20 * 0.75 = 15

Caroline made $15 profit.
