Subspaces 3. determine whether each of the subsets of the given vector space are a. is the set of polynomials ao + a1x + a2x2 +a3x*, for which ao = 0, a subspace of the set of all polynomials with degree less than or equal to three? b. is the set of polynomials ao + aix + a2x2 subspace of the set of all polynomials with degree less than or equal to three? azx3, for which ao + aj + a2 + a3 = 0, a + c. is the set of all functions f, such that f(x)

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:
