Answer 1

Given R (x) = 0.0726 x^2 + 1.3893x + 2.3578 (a) M (x) = R' (x) = 0.0726 times 2x + 1.3893 = 0.1452x + 1.3893 (b) For 400,000,000 (or) 4 hundreds of millions M (4) = R' (4) = 0.1452 times 4 + 1.3893 = 0.5808 + 1.3893 = 1.9701 hundreds of millions of dollars (c) For 750,000,000 (or) 7.5 hundreds of millions M (7.5) = R' (7.5) = 0.1452 times 7.5 + 1.3893 = 1.089 + 1.3893 = 2.4783 hundreds of million of dollars
