Question

How much of the initial mass remains after 80 years? (Round your answer to three decimal places.)

Answer 1

Given

`y=11((1)/(2))^{(t)/(30)}`

When t = 80

We substitute for t

`y=11((1)/(2))\frac{}{}^{(80)/(30)}`

Simplify

`y=11((1)/(2))^{(8)/(3)}`

Simplify further

`y=1.732g`

The final answer
