Answer:
5.6+8.5 divided by 2 times 6 = 42.3
If your looking for the percent you do 35 × 100, then divide by 175. You should get 20% as your answer.
I think it is B, but I'm not fully sure.
Answer a = 5 and b = 2.
Procedure
Initially means x = 0, then
5 = a*b^0 = a*1 = a, then a = 5
When x = 1, the height is the double of 5, i.e 10 and
10 = a.b^1 = a.b ⇒ b = 10/a = 10/5 = 2
The a = 5 and b = 2, so the equation is y =5(2)^x
