Set up a proportion:
4.1/22 = 12.3/x
Cross multiply:
4.1 * x = 22 * 12.3
4.1x = 270.6
Divide 4.1 to both sides:
x = 66
The formula for a cone is pi * r^2 * (h/3) or pi* r^2 * h * 1/3.
Since the height is 7ft and the radius if 4ft you plug those into the equation and get:
V= 1/3 * pi * (4^2) * (7)ft cubed which is the answer of B
Answer:
Kevin should do 21 shock replacements and 6 brake replacements every week to maximize his weekly income.
Step-by-step explanation:
Since either job takes 2 hours to complete, the total number of jobs that Kevin can complete working 54 hours a week is:

Since replacing shocks gives him a greater income, he should aim to do as little break replacements as possible and as many shock replacements as possible in order to maximize income.
If he has to complete at least 6 break replacements out of the 27 jobs possible, the number of shock replacements he should do is:

Kevin should do 21 shock replacements and 6 brake replacements every week to maximize his weekly income.
An Asymptote is a line that the plot or graph of a function tends to approach but will never touch. They are usually not part of the function graph.
This is illustrated as shown below
A vertical asymptote cannot be crossed by the graph function because it occurs at the x-value which is not in the domain of the function.
Hence, the correct answer is False.
