Since the road is smooth, R'(x) is continuous. What is the value of B? I think it involves some differentiation.. but I don't really know what to do. The options for answers are: a) .2 b) .02 c) .002 d) .0002 e) .00002 ?????????????????????????????????????????????????? |

The answer to this question depends on the relationship between the points x, A, and B. I am assuming that point A is at the origin, which is consistent with the expression for R(x), and the coordinates of point B would be (1000, 100). We have the equation 100 = R(1000) = a(1000)^2 = 1000000a Solving for a gives a = 0.0001 Because the derivative is also continuous, we also know that (ax^2)' = (bx + c)' at x = 1000 or 2ax = b at x = 1000 So b = 2(0.0001)*1000 = 0.2 OP |
