3) In the figure below, a ball is thrown from point A on top of an inclined plane of = 57°, with an initial velocity V0 and an angle . The ball takes 1.25 seconds to reach the maximum height of its trajectory (point B) and at this moment it is at a horizontal distance D = 3.7 m from the launch point. For this situation, calculate (a) the launch angle; (b) the initial velocity V0; (c) the total flight time between points A and C; (d) the velocity of the ball at the instant it reaches point C; and (e) the distance D between the launch point and the impact point. Tip: use the relationship sen(a)/cos(a)=tg(a)

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.

Acombination reaction is when two or more combine to form one product. a decomposition reaction is when a substance breaks down into two or more simpler substances in a chemical reaction.
