Formula: pi* r^2* h/3
Cone A= 12.57
Cone B= 50.27
f(x)=4x
To find the inverse, first change f(x) to y:
y = 4x
Now switch the variables:
x = 4y
Solve for Y:
Divide both sides by 4:
y = x/4
Now replace y with the inverse function f^-1(x):
f^-1(x) = x/4
Answer:
a) The line intersects with the circle once.
b) Tangent
Step-by-step explanation:
We are given the following equation for the circle:

How many times does the line y=-6 intersect with the circle?
We have to find the values of x when 
So





Since the line intersects the circle at one point, it is tangent to the circle.
The line intersects with the circle once.
