Find the exponential function P(t)=P0a^t where P(2)=5 and P(4)=10
asambeis [7]

Answer:

P(t)=\frac{5}{2} \cdot (\sqrt{2})^t

Step-by-step explanation:

P(2)=5 meants when t=2, that the value for P(t) is 5.

So this gives us this equation:

5=P_0 \cdot a^2

P(4)=10 meants when t=4, that the value for P(t) is 10.

So this gives us this equation:

10=P_0 \cdot a^4

So I take equation 2 and divide it be equation 1 I get:

\frac{10}{5}=\frac{P_0 \cdot a_4}{P_0 \cdot a_2}

Simplifying:

2=a^2

Since the base for an exponential function can't be negative then a=\sqrt{2}.

So plugging into one of my equations I began with gives me an equation to solve for the initial value,P_0:

5=P_0 \cdot (\sqrt{2})^2

5=P_0 \cdot 2

Divide both sides by 2:

\frac{5}{2}=P_0

The function is:

P(t)=\frac{5}{2} \cdot (\sqrt{2})^t

The number of visitors to a certain Web site triples every month. The number of visitors is modeled by the expression 300 •3m​,
muminat
We have that   <span>
</span>
the expression is (300)*(3^m)

for m=-1
​(300)*(3^-1)---------> (300)*(1/3)=100

The value of expression at m=-1 is 100, so there were 100 visitors 1 months before the number of visitors was measured
