More calculus! (i'm so sorry)
1. given the curve that is described by the equation r = 3 cos ф, find the angle that the tangent line makes with the radius vector when ф = 120°
a. 30°, b. 45°, c. 60°, d. 90°
2. a line rotates in a horizontal plane according to the equation ф = 2t^3 - 6t, where ф is the angular position of the rotating line, in radians, and t is the time, in seconds. determine the angular acceleration when t = 2 sec.
a. 6 radians per second^2, b. 12 radians per second^2, c. 18 radians per second^2, d. 24 radians per second^2
to get brainliest you have to be able to give me at least some reasoning or proof for the answers so that i know you didn't just get them off of google and they're legit answers.

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.
