Just substitute 4 for x in the given equation:
h(4) = 3^4 - 7 = 81 - 7 = 74 (answer)
Answer:
I. 94.99 in²
II. $0.23
Step-by-step explanation:
<u>Given the following data;</u>
Diameter of wheel = 11 inches
Cost of wheel = $21.35

<em><u>Part A</u></em>
To find the area;
We know that a wheel is circular in nature. Thus, the area of a circle is given by the formula;
Substituting into the equation, we have;
<em>Area, A = 94.99 in²</em>
<em><u>Part B</u></em>
To find cost per square inch;
<u>Cost per square inch = $0.23</u>
Answer:
the reflection is across the x- axis
Step-by-step explanation:
if you see that the y's in the second graph are negative then the reflection is across the x-axis
Answer:
9
Step-by-step explanation:
Let's first convert this to numbers. When a number is decreased by a certain amount, that is the same as saying that something is subtracted from it. Therefore:
a-7=2
Add 7 to both sides:
a-7+7=2+7
a=9
Hope this helps!
First, let's find g(4). After we find it, we can substitute the value into
.
To find g(4), we need to substitute x = 4 into the function
, as shown below:



Now that we have found g(4) = 9, we can substitute this value in for
in
.



f(g(4)) is equal to 28.
