1. Factor the expression 

2. Since
is placed in the denominator of the given expression, then 
3. Now the expression can be simplified:

Answer:
Assuming that v0 represents the initial velocity, then v0 = 96 ft/s. Substitute this value into h(t) and set the equation equal to 48. Then, write this quadratic equation in standard form, which is ax² + bx+ c = 0, where a, b, and c are constants. Either use factoring or the Quadratic Function to solve the equation for t. Remember that t must be positive, because it represents a unit of time.
They would be the same because the formula is volume equals pi radius squared times height. So you would use the radius of 1.5 instead of the diameter of 3
Answer:
c) $615
Step-by-step explanation:
The expression used to determine how much is the charge for the customer after the job is

where
h is the number of hours the job took
c is the number of cans of paint used during the job
In this problem:
c = 3 (the painter used 3 cans of paint)
h = 15 (the painter took 15 hours for the job)
So substituting these values into the equation for p, we find the total value that the painter charged for the job:

So, the correct answer is
c) $615
