Answer:

a)

Since the radius of the balloon increases by 5 cm every second, the amount of time passed in seconds multiplied by 5 will give us the radius at any given point in time

So, f(t) = 5t

b)

Since the surface area of a sphere is 4\pi (r)^2

We already have the radius of the sphere at any given time from our first equation

SA(t) = 4\pi (5t)²

Kindly Mark Brainliest, Thanks!

For f(x)=-2x^3-4x^2+3x-8 , use the remainder theorem to determine f(-1).
konstantin123 [22]

Answer:

- 13

Step-by-step explanation:

Substitute x = - 1 into f(x) to obtain the remainder on dividing by (x + 1)

f(- 1) = - 2(- 1)³ - 4(- 1)² + 3(- 1) - 8

       = 2 - 4 - 3 - 8 = - 13

Thus the remainder on dividing f(x) by (x + 1) is - 13
