If an arrow is shot upward on Mars with a speed of 58 m/s, its height in meters t seconds later is given by y = 58t − 1.86t2. (Round your answers to two decimal places.) (a) Find the average speed over the given time intervals. [1, 1.01]

- (2, -7)

- lines r and s and lines t and u must be parallel

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
