A vertical asymptote simply means that the function is undefined at a certain point. We are given that it occurs at x=25. Notice that x is in the denominator and if the denominator equals 0, the entire function is undefined. <em>a</em> and <em>k</em> are simply constants, and so they can take on any value. This is one of infinite solutions to this question:

Notice that when you plug in x=25, the denominator is 0 and the function is undefined making it a vertical asymptote.
Hope I could help!
Answer:
625 pi (no approximation)or 1962.5(approximation)
Step-by-step explanation:
You do pi times radius squared.
Answer:
y=3/4x -2
Step-by-step explanation:
I know the last box has a plus sign in front of it but it's still -2 since the y- intercept is at -2. It's the same thing but I just wanted to make sure you knew that in the last box, you still put -2.
Sorry if what I just said above is confusing, i don't know how to explain it better...
Radius is 5 cm. is the answer
(3/5)(2/5)=6/25
