Question

CAN ANYBODY PLEASE HELP ME FOR BRAINLIEST, I'VE BEEN ASKING FOR DAYS AND POSTING DAILY THE SAME QUESTION :(

Answer 1

Answer:  $y = 650(0.907)^t$

This is the same as writing y = 650(0.907)^t

=====================================================

Explanation:

Exponential equations can be of the form y = a*b^t

• a = initial amount
• b = growth or decay factor

In this case, we have

• a = 650 mg to start with
• b = 1 - 0.093 = 0.907 as the decay factor

If we had exponential growth, then we'd compute 1 + 0.093 instead.

Based on those values, we go from y = a*b^t to y = 650(0.907)^t which is the same as writing $y = 650(0.907)^t$

Other exponential forms are possible, but I think this form is the most intuitive. The 0.907 means that 90.7% of the sample remains after each year.
