If the half-life of a drug in the bloodstream is 15 hours, how much drug is left in the bloodstream after 2 days when
the initial dose was 400 milligrams? [Round your answer to the nearest tenth.]
435 milligrams

the answer is a) y= 2 csc [0.5 (x+pi/2)]-1

step-by-step explanation:

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !

um is there supposed to be a picture?
