Answer:
24.5
Step-by-step explanation:
the radius is half of a diameter
so the radius is 3.9
24.5 = 2πr= 2 * π * 3.9 ≈ 24.504
Answer:
(0,2)
Step-by-step explanation:
I'm going to assume you meant Which point is ON the graph of f(x) = 2 * 5^x?
In order to do this question, all you need to do is pick any number as x. Lets pick 0 in this case.
f(x) = 2 * 5^x
f(0) = 2*5^0
= 2*1
= 2
So one point on the graph would be (0,2)
Why?
Because remember with functions, the f(x) can be swapped out with y, so when x = 0, y = 2.
Answer:
8 : 6
4 : 3
Step-by-step explanation:
The first step for solving this problem is to know that in order to divide by a fraction,, we must multiply by the reciprocal of that fraction. This will look like the following:

× 9x
Write -6x as a difference.

× 9x
Factor out x from x² + 2x.

× 9x
Factor out -8 from -8(x + 2).

× 9x
Factor out x + 2 from the denominator (bottom) of the expression.

× 9x
Reduce the fraction with x + 2

× 9x
Finally,, calculate the product to find your final answer.

This means that the correct answer to your question is going to be option B.

Answer:
<h3>
Therefore total amount of money that he got is = $(5+0.50x) [ x = number of correct math]</h3>
Step-by-step explanation:
Given, Gilberto's grandfather gives him $5 for his birthday and then$0.50 for each math he answers correctly on his math exam for the year.
Let , the number of math that he answers correctly on his his math exam for the year is x
Therefore he got = $(0.50× x) =$ 0.50x for doing correct math.
Therefore total amount of money that he got is = $(5+0.50x) [ x = number of correct math]
