Arock is thrown straight up from the top of a bridge that is 75 ft high with an initial velocity of 32 ft/s. the height of the object can be modeled by the equation s ( t ) = -16 t2 + 32 t + 75. determine the time(s) the ball is lower than the bridge. write your answer in interval notation.
in two or more complete sentences, explain why (-∞,0) is not included in the solution.

positive

step-by-step explanation:

the quadrant is facing upwards

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i
