Answer:
B
Step-by-step explanation:
We are given the function:

And we want to determine the value of:

Let this value equal <em>a</em>. In other words:

Then by the definition of inverse functions:

Hence:

Solve for <em>a: </em>

By the Zero Product Property:

Hence:

Thus, f(9) = 225. Consequently, f⁻¹(225) = 9.
In conclusion, our answer is B.
Answer:
2 in
Step-by-step explanation:
Use the cube volume formula, V = s³, where s is the side length
Plug in 8 as V and solve for s:
V = s³
8 = s³
Take the cube root of both sides:
2 = s
So, the length of one side is 2 inches.
B = 144
a = 4/5s
s = a + 24
s = 4/5s + 24
5/5s - 4/5s = 24
1/5s = 24
s = 24 * 5
s = 120
a = 4/5s
a = 4/5(120)
a = 480/5
a = 96
blueberry pies = 144
total of all pies = 144 + 120 + 96 = 360
percent of blueberry pies is : 144/360 = 0.40 = 40% <==
