Ahigh definition radio station charges $200 per year in addition to $50 per month for the first 3 months to receive its broadcast. write a function using function notation to describe the situation.

Let's assume

number of months =x

A high definition radio station charges $200 per year

so, we get point as (0,200)

Assume

f(x) is the total amount of charges in a year

we can see that this is linear relationship

so, we can use formula

in addition to $50 per month for the first 3 months to receive its broadcast

so, m=50

we can plug it

we can use point as (0,200)

now, we can plug it back

and we get

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
