Answer:
![(a)\ f^{-1}(-15) = -6](https://tex.z-dn.net/?f=%28a%29%5C%20f%5E%7B-1%7D%28-15%29%20%3D%20-6)
![(b)\ f^{-1}(4) + f(9)=0](https://tex.z-dn.net/?f=%28b%29%5C%20f%5E%7B-1%7D%284%29%20%2B%20f%289%29%3D0)
Step-by-step explanation:
Given
The attached table
![(a)\ f^{-1}(-15)](https://tex.z-dn.net/?f=%28a%29%5C%20f%5E%7B-1%7D%28-15%29)
This represents an inverse function.
So, we look into x row for its value.
i.e.
![f^{-1}(-15) = -6](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28-15%29%20%3D%20-6)
![(b)\ f^{-1}(4) + f(9)](https://tex.z-dn.net/?f=%28b%29%5C%20f%5E%7B-1%7D%284%29%20%2B%20f%289%29)
Just like (a)
---- by looking into the x rows
![f(9) = 11](https://tex.z-dn.net/?f=f%289%29%20%3D%2011)
So:
![f^{-1}(4) + f(9)=-11 + 11](https://tex.z-dn.net/?f=f%5E%7B-1%7D%284%29%20%2B%20f%289%29%3D-11%20%2B%2011)
![f^{-1}(4) + f(9)=0](https://tex.z-dn.net/?f=f%5E%7B-1%7D%284%29%20%2B%20f%289%29%3D0)
Answer:
Let's use the formula for the volume of a rectangular prism;
V = l · w · h
Where 'l' represents the length, 'w' stands for the width, and 'h' displays as the height. (V evidently stands for the volume)
<u>What we know:</u>
- Volume = 240 ft
- Length = 4 ft
<u>What we need to find out:</u>
Let's plug in what we know into the formula:
V = l · w · h
<u>240</u> = <u>4</u> · <u>4</u> · h
Now let's solve for h:-
240 = 16 · h
240 = 16h
Get rid of h's co-efficient by dividing 16 from both sides because the inverse operation of multiplication(since 16 is being multiplied by h) is division.
÷16 ÷16
Finally, you would end up with a result of:
<u>15</u> = h
Hence, the height of this prism is <u>15 feet</u>.
512. If you times 8 by 8 by 8 you will get 512
Answer:
The height of the prism is 13
