Step-by-step explanation:
You know that:
- She uses 6 liters of fruit juice.
- She uses 0.6 as much sparkling water as fruit juice.
Therefore, let's call x the amount of fruit punch she made.
Keeping the above on mind, you can solve the problem by multiplying the 6 liter of fruit juice she uses by 0.6.
Therefore the result is:
Answer:
The population will reach 34,200 in February of 2146.
Step-by-step explanation:
Population in t years after 2012 is given by:
In what month and year will the population reach 34,200?
We have to find t for which P(t) = 34200. So
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
.
This polynomial has roots such that
, given by the following formulas:
In this question:
So
Then
We only take the positive value.
134 years after 2012.
.14 of an year is 0.14*365 = 51.1. The 51st day of a year happens in February.
So the population will reach 34,200 in February of 2146.
