Answer:

5 years

Step-by-step explanation:

If the population of penguins is given by the function:

P(t)=P_0\cdot 3^{t/5}

Initial Size =P_0

Triple its Initial Size, P(t)=3P_0

Therefore:

3P_0=P_0\cdot 3^{t/5}\\$Divide both sides by P_0\\3=3^{t/5}\\$Since they have the same base\\1=t/5\\Cross multiply\\t=5

It therefore takes 5 years for the penguin population to triple in size.

12-3(2w+1)=7w-3(7+w) \\ \\ 12-6w-3=7w-21-3w \\ \\ 9-6w=4w-21 \\ \\ -6w-4w=-21-9 \\ \\ -10w=-30 \\ \\ \boxed{x=\frac{-30}{-10}=3}

larisa [96]

Answer:

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.
