A group of students go out on a boat to go scuba diving. The instructor takes the group 57.52 feet below the surface to start. Then they go up 24.88 feet and stop to see some fish. Estimate the total change in distance from where they started at the surface. Find the total change in distance from where they started at the surface..

it is  82.13

Step-by-step explanation:

you can add the 57.52+24.88

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)
