If you would please attach a figure to the question I might be able to answer it.
Step-by-step explanation:
The colony die out when the population becomes 0. i.e. P(t) = 0.
-5t + 54 = 0
5t = 54
t = 54/5
t = 10.8
Therefore, the collony will die out after 10.8 minnute (10 minutes 48 seconds)
Let Jeremy's age be x
if Jeremy's grandfather is four times as old as he is,grandfather's age is 4x
if the sum of their ages is 90, we have
x%2B4x=90
5x=90
x=90%2F5
x=18->Jeremy's age
Jeremy's grandfather will be 4x=4%2A18=72
answer:
D. 72
