The half-life of a radioactive substance is 15 years old. Write an equation that can be used to determine the amount, s(t), of 200 grams of the substance that remains after t
years.

step-by-step explanation:

try remembering the steps

51-50

step-by-step explanation:

the answer is y = 11.54

hope this : )

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
