Qual a massa de um átomo cujo Z (n° atômico) é 17 e possui 9 N (NEUTRONS)?
apresente os cálculos

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)

i would say true? if the unit was informational and it "refreshed your understanding", then true.

might be the correct answer will be question number 2
