Answer: t^2 = 36 or 1
Step-by-step explanation: Divide everything by -5, and get t^2 -6t -5=0, Factoring is (t-6)(t+1), so t=6 or t=-1. Both squared are 36 and 1 so either of these could be the answer. Hope this helps!

and

We need to determine the rate of change of population.
The rate of change can be determined using the formula,

where
and 
Substituting the values in the formula, we have,

Simplifying, we have,

Dividing, we get,
220
Thus, the population is increasing at the rate of 220
Answer:

Step-by-step explanation:
1, 1, 1, 1, 4, 7, 7
Median (middle) = 1
Mode (most common) = 1
Range (largest# minus smallest#) = 6
5, 10, 10, 15, 15, 15, 20
Median = 15
Mode = 15
Range = 15
