Solve the problem.To remodel a bathroom, a contractor charges $25 per hour plus material costs, which amount to $3550. Therefore, the total cost to remodel the bathroom is given by 
where x is the number of hours the contractor works. Find 
What does 
compute?
A. f -1(x) = 
- 3550; This computes the total cost if the contractor works x hours.
B. f -1(x) = 
- 3550; This computes the number of hours worked if the total cost is x dollars.
C. f -1(x) = 
- 142; This computes the total cost if the contractor works x hours.
D. f -1(x) = 
- 142; This computes the number of hours worked if the total cost is x dollars.
Solve the problem.A formula used to determine the velocity v in feet per second of an object (neglecting air resistance) after it has fallen a certain height is 
where g is the acceleration due to gravity and h is the height the object has fallen. If the acceleration g due to gravity on Earth is approximately 32 feet per second, find the velocity of a bowling ball after it has fallen 20 feet. (Round to the nearest tenth.)
A. 1280 ft per sec B. 35.8 ft per sec C. 25.3 ft per sec D. 6.3 ft per sec
