Which statement is true about the evidence for the Big Bang Theory?
A. Amount of cosmic microwave background radiation is constant, implying contraction.

B. Most distant stars are moving away at faster speeds than those closer.

C. Amount of cosmic microwave background radiation fluctuates, implying expansion.

D. Most distant stars are moving away at slower speeds than those closer.

lol we need to see what the question is asking about

step-by-step explanation:

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

step-by-step explanation:

v=4

3πr3=4

3·π·33≈113.09734
