Asoccer ball is kicked from the top of one building with a height of h1 = 32.0 m to another building with a height of h2 = 13.8 m. (it is not a very smart idea to play soccer on the roof of tall buildings.) the ball is kicked with a speed of v0 = 16.1 m/s at angle of ? = 78.0° with respect to the horizontal. how much time will the ball spend in the air before it hits the roof of the other building? (the soccer ball is kicked without a spin. neglect air resistance.)

Atank holds 1000 gallons of water, which drains from the bottom of the tank in half an hour. the values in the table show the volume v of water remaining in the tank (in gallons) after t minutes. t(min) 5 10 15 20 25 30v(gal) 694 444 250 111 28 0(a) if p is the point (15, 250) on the graph of v, find the slopes of the secant lines pq when q is the point on the graph with t = 5, 10, 20, 25, and 30.(b) estimate the slope of the tangent line at p by averaging the slopes of two secant lines.(c) use a graph of the function to estimate the slope of the tangent line at p. (this slope represents the rate at which the water is flowing from the tank after 15 minutes.)show all steps.
