Helppp I will give you the brain thing and a thank you .

see below

Step-by-step explanation:

The surface area of a cylinder is

SA = 2 pi r^2 + 2 pi rh  because there is a top and a bottom

     = 2 * pi (5)^2 + 2 * pi (5) (10.6)

   = 50 pi + 106pi

  = 156 pi

  =489.84 yd^2

its adding 5.5 each time

step-by-step explanation:

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
