The highest desirable pulse rate, p, in beats per minute, for people exercising is given by the formula p = 0.8(220 – a), where a is the person’s age, in years. What is the highest desirable pulse rate for a 20-year-old?

think the answer would beb

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)
