The half life of substance A is 18 18 years, and substance B decays at a rate of 30 30 % each decade. (a) Find a formula for a function () f ( t ) that gives the amount of substance A, in milligrams, left after t years, given that the initial quantity was 100 100 milligrams.

answer: i'm not sure

step-by-step explanation:

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)

i can answer this if i have the answer choices

i think the answer is b x = 1, y = 35/2
