Many people suffering from constricted bronchial muscles inhale the drug Albuterol for
relief. The number of micrograms A of Albuterol in a person's bloodstream t minutes
after 200 micrograms have been inhaled can be approximated by
A = -50t^ +170t.
How long after an inhalation will there be about 60 micrograms of Albuterol in the
bloodstream? Round to the nearest tenth of a minute. (hint: Divide by 10)

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

answer: 323 is how many she has ☃☃⛄❄
