answer: a. 74

step-by-step explanation:

it shows divided evenly, so add the 37+37 = 74

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.

the answer is b.

64

step-by-step explanation:

c=2πr=2·π·8≈64
