1.Suppose that the manufacturer of a gas clothes dryer has found that when the unit price is p dollars, the revenue R (in dollars) is R(p)=−5p2+15,000p.
(a) At what prices p is revenue zero?
(b) For what range of prices will revenue exceed $1,500,000?
2. A ball is thrown vertically upward with an initial velocity
of 80 feet per second. The distance s (in feet) of the ball from
the ground after t seconds is s=80t-16t2.
(a) At what time t will the ball strike the ground? (b) For what time t is the ball more than 84 feet above the ground? |
The solutions are given below

A ball is thrown vertically upward with an initial velocity of 48 feet per second. The distances (in feet) of the ball from the ground after t seconds is s=48-16t2. (a) At what time t will the ball strike the ground? (b) For what time t is the ball more than 32 feet above the ground?
A ball is thrown vertically upward with an initial velocity of 96 feet per second. The distance s (in feet) of the ball from the ground after t seconds is s(t)=96t-16t^2a.) at what time will the ball strike the groundb.) for what time t is the ball more than 128 feet above the ground?c.) when will the ball reach its highest peak? how high is it above the ground?
2and screenshot of the question please provide me the answers Thanks Suppose that the manufacturer of a gas clothes dryer has found that, when the unit price is p dollars, the revenue R (in dollars) is R(p) = -7p2 + 21,000p What unit price should be established for the dryer to maximize revenue? What is the maximum revenue? The unit price that should be established to maximize revenue is (Simplify your answer.) The maximum revenue is so (Simplify your answer.)...
ine more screenshot just to make it clear please help me the answer. Thanks Suppose that the manufacturer of a gas clothes dryer has found that when the unit price is p dollars, the revenue R (in dollars) is + 21000p What unit price should be established for the dryer to maximize revenue? What is the maximum revenue? R(P)= - 7p? The unit price that should be established to maximize revenue is (Simplify your answer.) The maximum revenue is S...
6. Thorough algebraic work to support the results is required for credit. A ball is thrown vertically upward from the top of a building 80 feet tall with an initial velocity of 43 feet per second. The distance, s (in feet), of the ball from the ground after t seconds is given by the function: als s(t) = 96 + 43t - 16t2 luty 1919 ini a. How long does it take for the ball to reach its ! highest...

Please show complete work with necessary unit for full credit. Problem 1: A ball is thrown up vertically from the top of a building of height-100 m with an initial speed of 30 m's. It then goes up for a certain period of time and then comes down to the ground. Neglect the air resistance for calculation (a) How high from the ground will the ball go? (b) How long will it take for the ball to reach to the...
Free-fall notion 1. A ball is thrown vertically upward at an initial speed of 49 m/s. Assume that the ball leaves the hand when it is 15 m above the ground (about the height of Kirkbride), and that the effects of air resistance can be ignored. Choose your landmark to be the ground; then at t -0, yo- +15 m, Vyo +49 m/s a. 5 pts) How fast is the launch speed in mph? Do you think this is a...

Please answer the following physic questions. Thank you! 1. A dog sees a flowerpot sail up and then back past a window 5.0 ft high. If the total time the pot is in sight is 1.0 seconds, find the height above the window that the pot rises. 2. An elevator ascends with an upward acceleration of 4.0 ft/s2. At the instant its upward speed is 8.0 ft/s, a loose bolt drops from the ceiling of the elevator 9.0 ft from...
