An adult takes 400 mg of ibuprofen. Each hour, the amount of ibuprofen in the person's
system decreases by about 29%.
What is the exponential model?
y = 400 (0.71)
y = 400 (3.9)
Y = 400 (1.29)
SONY

y=x+9

?

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)

(x) - (y) = (1 + 4i)

answer: 8 years

step-by-step explanation:

the explanation is that in 8 years the child will be 20 and in 8 years the father will be 40 and 20 is half of 40.
