Carbon -14 decays exponentially according to the model A= Aoe ^-0.00012t where t is measured in years. If there was an initial amount of 700 grams how much would remind after 80 years?

after how many years would there be 215 grams?

there are no figures how am i supposed to answer this question

step-by-step explanation:

2? if not the correct answer you might need to provide more information

step-by-step explanation:

can you make your screen more see able?

then i might be able to .

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
