Solve the problem.A baseball player hit a baseball with an initial speed of 150 feet per second at an angle of 40° to the horizontal. The ball was hit at a height of 4 feet off the ground. Find parametric equations that describe the motion of the ball as a function of time. How long is the ball in the air? When is the ball at its maximum height? What is the distance the ball traveled?

A. x = 114.9t, y = -16t2 + 96.45t + 4
12.139 sec, 3.014 sec,
1394.771 feet
B. x = 114.9t, y = -16t2 + 96.45t + 4
6.069 sec, 3.014 sec,
1174.679 feet
C. x = 114.9t, y = -16t2 + 96.45t + 4
6.069 sec, 3.014 sec,
697.328 feet
D. x = 114.9t, y = -16t2 + 96.45t + 4

Solve the problem.To remodel a bathroom, a contractor charges $25 per hour plus material costs, which amount to $3825. Therefore, the total cost to remodel the bathroom is given by where x is the number of hours the contractor works. Find a formula for What does compute?

A. f^-1(x) =  - 3825; This computes the total cost if the contractor works x hours.
B. f^-1(x) =  - 153; This computes the total cost if the contractor works x hours.
C. f^-1(x) =  - 153; This computes the number of hours worked if the total cost is x dollars.
D. f^-1(x) =  - 3825; This computes the number of hours worked if the total cost is x dollars.
