The value of a rare baseball card issued in 1989 is represented by the function f(x) = 0.2x^3 - 25x² + 3x + 4 where x represents the number of years since the baseball card
was issued. Use the remainder Theorem to find the value of the card in 1999.

The function a represents the cost of manufacturing product a, in hundreds of dollars, and the function b represents the cost of manufacturing product b, in hundreds of dollars. a(t) = 5t + 2 b(t) = 7t - 2t +4 find the expression that describes the total cost of manufacturing both products, a(t) + b(t). a. 7t^2 - 7t + 2 b. 7t^2 + 3 +6 c. 7t^2 + 7t - 6 d. 7t^2 - 3t + 6
