1. What is the half-life of the radioactive isotope with amount A, whose rate of decay in t hours is shown in the graph below? (0,50)
(30, 10)

gdp is the best phrase!

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

step-by-step explanation:

55 because 55 + 55 = 110 good luck babe
