VX Ericka decided to compare her observation to the
average annual trend, which shows the water rising 1.8
mm/year. Remember, she used 6.2 years as her time
period. Explain how she would calculate the difference
between how much water levels rose on average and
how much the water level fell in the part of the river she
observed.

22.83 repeating

step-by-step explanation:

137 ÷ 6 is 22.8333333 therefore we understand that 3 is repeating.

step-by-step explanation:

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)
