Answer: 70 ft
Step-by-step explanation:
Given
height of book is measured by the function is

when the book is thrown 

The height of the book is 
By definition, we have

So, we have to solve two different equations, depending of the possible range for the variable. We have to remember about these ranges when we decide to accept or discard the solutions:
Suppose that 
In this case, the absolute value doesn't do anything: the equation is

We are supposing
, so we can accept this solution.
Now, suppose that
. Now the sign of the expression is flipped by the absolute value, and the equation becomes

Again, the solution is coherent with the assumption, so we can accept this value as well.
30%÷100% = 0.30; $85×0.30= $25.50; 85 - 25.50= $59.50.
15%÷100% = 0.15; $59.5 ×0.15 =8.92; 59.50 - 8.92= $50.58
$50.58
Answer:
Assuming you mean a rectangular prism, cube, or triangular prism,the volume would be 384.
Step-by-step explanation:
Well volume for those two shapes could be b*h
SO base times height is always gonna give you volume for most shapes
Answer:
10
Step-by-step explanation:
f(x) =3x-x=2x,
f(7-2)=f(5)= 2*5=10
