Answer:
C
Step-by-step explanation:
Using Pythagoras' identity in right triangle BPO
with PB = 4 ( half of AB ) and OB = 5 ( radius of circle )
OP² + 4² = 5²
OP² + 16 = 25 ( subtract 16 from both sides )
OP² = 9 ( take the square root of both sides )
OP = 
= 3

Answer:
h(f(x)) = 2x - 11
Step-by-step explanation:
h(f(x)) is a "composite function." We use the function f(x) as the input to the function h(x):
h(x) = 2x + 3, or 2( x ) + 3; replacing x with f(x), or x - 7, we get:
h(f(x)) = 2(x - 7) + 3, or
h(f(x)) = 2x - 14 + 3, or
h(f(x)) = 2x - 11
Answer
456.50=159 + 3.5x
OR
3.5x=456.50-159
Reason
456.50 is the total
159 is for the parts
3.5 is the number of hours
So to find the cost you have to find out how much it cost for the labor by subtracting the total cost from the cost of the parts. To find the cost of labor for each hour you have to divide the total cost of labor by the number of hours used to work on the computer
