Solve the problem. 1) Ken is 6 feet tall and is walking away from a streetlight. The streetlight has its light bulb 14 feet above the ground, and Ken is walking at the rate of 1.4 feet per second. Find a function, d(t), which gives the distance Ken is from the streetlight in terms of time. Find a function, S(d), which gives the length of Ken's shadow in terms of d. Then nd (S d)(t). A) (S d)(t) = 0.77t B) (S d)(t) = 1.33t C) (S d)(t) = 1.05t D) (S d)(t) = 2.37t 2) The function f(x) = 60x computes the number of minutes in x hours. The function g(x) = 24x computes the number of hours in x days. What is (f g)(x) and what does it compute? A) (f g)(x) = 84x; It computes the number of minutes plus the number of days in x days....
