If an arrow is shot upward on mars with a speed of 54 m/s, its height in meters t seconds later is given by y = 54t − 1.86t^2. (round your answers to two decimal places.) (a) find the average speed over the given time intervals. (b) estimate the speed when t = 1.

-10i^2-4i

step-by-step explanation:

evaluate for p=2,q=5i

(2−4)(2+5i)i

(2−4)(2+5i)i

=−10i2−4i

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
