Question

Assume A varies directly as B^2. If B is multiplied by 3.55, how will it affect A. In other words: if we multiply B by 3.55, by how much would we have to multiply A, in order to preserve the same coefficient of proportion?

Write your answer as a decimal rounded to two decimal places.

Answer 1

Answer: 12.60

Step-by-step explanation: A = B^2. If B is multiplied by 3.55, then A = (3.55B)^2. That gives us A = 12.6025B. Round 12.6025 to hundredth and you get 12.60
