PLEASE HELP ASAP, I WILL GIVE BRAINLESSLY ANSWER <br> SHOW WORK PLEASE
zhannawk [14.2K]

Answer:

C. N(t)=150\cdot 3^t

Step-by-step explanation:

You are given the exponential function n(t)=ab^t.

From the table, N(t)=150 at t=0, thus

N(0)=a\cdot b^0\\ \\150=a\cdot 1\ [\text{ because }b^0=1]

Also N(t)=450 at t=1, thus

N(1)=a\cdot b^1=a\cdot b.

Since  a=150, substitute it into the second equation

450=150\cdot b\\ \\b=\dfrac{450}{150}\\ \\b=3

and the expression for the exponential function is

N(t)=150\cdot 3^t
