If a ball is thrown upward at 19.6 meters per second from the top of a building that is 35 meters high, the height of the ball can be modeled by S=35+19.6t−4.9t2, where t is the number of seconds after the ball is thrown. Answer parts a through c.
a. Find the t-coordinate and S-coordinate of the vertex of the graph of this quadratic function.
The t-coordinate of the vertex of the graph of this quadratic function is t=nothing.
(Simplify your answer.)

1. an economy consists of three workers: larry, moe, and curly. each works 10 hours a day and can produce two services: mowing lawns and washing cars. in an hour, larry can either mow one lawn or wash one car; moe can either mow one lawn or wash two cars; and curly can either mow two lawns or wash one car. a. calculate how much of each service is produced under the following circumstances: a. all three spend all their time mowing lawns. b. all three spend all their time washing cars. c. all three spend half their time on each activity d. larry spends half of his time on each activity, while moe only washes cars and curly only mows lawns b. using your answers to part a, draw a production possibilities frontier and label points a, b, c, and d on your graph. explain why the production possibilities frontier has the shape it does. c. are any of the allocations calculated in part a inefficient? explain.
