Vincent's cell phone plan charges a $10.00 monthly access fee and $0.04 for each text message sent. Which expression below represents the total monthly charge Vincent will have to pay if he sends n text messages this month?

a. 10.00 + 0.04 + n

b. 10.00 + 0.04n

c. 10.00n + 0.04

d. (10.00 + 0.04)n

B.

Step-by-step explanation:

THe base fee is $10, and the you pay $0.04 for every text

SO the equation should be $10 + $0.04n

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!

(c, 0) i might be wrong so don't put full faith on my answer
