Answer:
Distributive Property
Step-by-step explanation:
If the given statement is
5(72 – 3y) = 360– 15y
When we apply the distributive property to the left hand side we get;
When we simplify we get
Therefore the distributive property justifies the given statement.
Answer:
It takes 7.37 hours for the size of the sample to double.
Step-by-step explanation:
Continuous exponential growth model:
The continuous exponential growth model for populations is given by:
In which P(0) is the initial population and r is the growth rate parameter, as a decimal.
Growth rate parameter of 9.4% per hour.
This means that
So
How many hours does it take for the size of the sample to double?
This is t for which P(t) = 2P(0). So
It takes 7.37 hours for the size of the sample to double.
