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

Which values are in the solution set I x-4 I =8?
hodyreva [135]

Answer:

x = 12        and    x = -4

Step-by-step explanation:

abs (x-4) = 8

When we have absolute value equations, we get two solutions, one positive and one negative

x-4 = 8        and   x-4 = -8

Add 4 to both sides

x-4+4 = 8+4       x-4+4=-8+4

x = 12        and    x = -4
