Triple C Ranch (TCR) grows corn. The market supply for corn is Qs = -9 +4P Market demand is Qd = 40 – 3P. TCR’s cost function is 26 + 2q +0.17?, where q is the output of corn in ears. a) (10) Derive the average cost function, the marginal cost function, and the average fixed cost function, and graph them on a single graph. b) (5) What is the market price of corn? c) (15) What is TCR's profit-maximizing...
A stone is tossed vertically into the air from ground level with an initial velocity of 15 m/s. Its height at time t is h(t)=15t-4.9t^2.Compute the stone's average velocity over the time interval [0.5, 2.5]. It says the answer is .3, but I keep getting something not close to that...
