Ming throws a stone off a bridge into a river below. The stones height in meters above water, x seconds after Ming threw it, is modeled by: h(x)= -5(x-1)+45. What is the maximum height that the stone will reach?

If cos(2x) = tan^2(y), show that cos(2y) = tan^2(x).

‼️‼️‼️‼️‼️the pressure exerted on the walls of a container by a gas enclosed within it is directly proportional to the temperature of the gas. if the pressure is 6 pounds per square inch when the temperature is 440 f, find the pressure exerted when the temperature of the gas is 380°f. (show work)
