1 answer:

7 0

We are asked in the problem to convert 17 pi over 4 in to an angle that is less than or equal to 360 degrees. 17 pi over 4 is equal to 756 degrees. To answer this, we subtract 765 by 360 until the angle is les than 360. The answer is a. 45

If you invested $500 at 5% simple interest for 2 years, how much interest do you earn? Show work and answer in

I will invest in simple interest as the interest there is more.

Step-by-step explanation:

If I invested $500 at 5% simple interest for 2 years, then the interest that I will get will be given by the formula

$I = P \times \frac{rt}{100}$ , where P is the invested principal, r is the APR and t is the time in years.

So, in our case, $I = 500 \times \frac{5 \times 2}{100} = 50$ dollars. (Answer)

Now, if I invest $500 at 3% compound interest compounded monthly for 2 years.

Now, using the formula of compound interest we have

$I = P(1 + \frac{r}{n \times 100} )^{tn} - P$ , where r is the APR and n is the number of times in a year the principal is compounded.

In our case, $I = 500(1 + \frac{3}{12 \times 100} )^{2 \times 12} - 500 = 30.88$ dollars. (Answer)

Therefore, I will invest in simple interest as the interest there is more. (Answer)

Main Idea: To evaluate an exponential growth or decay function, substitute a value for the exponent variable and simplify.

Helen [10]

If there is more to the answer than what I give please ask for more!

With $F(x) = 3^{x}$ we can find $F(4)$ by substituting 4 into the main function.

So it would look like this: $F(4) = 3^{4} = 3*3*3*3 = 81$

Hope this helps!

The formula V=arh gives the volume of a cylinder with radius r and height h. Find the volume of a cylinder with radius (x + 4) c

marishachu [46]

Answer:

V = a (x + 4)*5 but see below.

Step-by-step explanation:

You're not going to get any kind of answer that gives V = 122 or some other pure number.

Formula

V = arh

Givens

a = pi * r

r = (x + 4)

h = 5cm

Solution

V = a * (x + 4)*5

V = pi * (x + 4)^2 * 5

There is no indication of which one to choose.

James knows that when he walks, he takes about 120 steps per minute and that each step is 2.75 feet long.

Degger [83]

Answer:

Speed=120step/min=720step/h

Distance=720step/h×2.75feet/step=1980feet/h=0.375miles/h

So the answer is: he can walking 0.375miles per hour

Divide. write your answer in simplest form. 7/9 divided by 8/15

Sever21 [200]

Answer:35/24

Explanation:
7/9 divided by 8/15 can also be written as 7/9 x 15/8. We multiply the top and the bottom. It would look like 7x15/9x8. That equals 105/72. Simplified it is 35/24
