A) Find the value of k that makes p(x) continuous, given p(x) =
sqrt(3x + 7) FOR X <= 3
x^2 - xk FOR x > 3
B) Find the value of k that makes f(x) continous if f(x) =
- abs(x-2)+k FOR X <=4
-kx^2 - kx - 23 FOR X > 4

A Spherical balloon is inflated with helim at the rate of 100%u03C0 ft^3 / min
A) How fast is the balloon's radius increasing at the instant the radius is 5 feet?
b) How fast is the surface area increasing at that instant?
So yeah answering these 8 questions will be a huge help to him ^_^
I'm gonna have him do what he can on them right now but at the very least I can use any help I get from b8 to correct his work.
