Don cheTD invested $ 6,300 in Account in the year 20066, Its been reached $8,200 in 2010
Determine the value of the account in 2019

y = abᵗ

we know the initial amount is 6300 on 2006, that's on year 0, namely t = 0.

we also know that it became 8200 on 2010, that's 4 years later, namely t = 4.

what would its value be in 2019, well that's t = 13.

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)
