We have the following function:
f(t) = −16t2 + 34t + 546
By definition, the average rate of change is:
Avr = (f (t2) - f (t1)) / (t2 - t1)
We have then:
For t1 = 5:
f (5) = -16*(5)^2 + 34*(5) + 546
f (5) = 316
For t2 = 5:
f (7) = -16*(7)^2 + 34*(7) + 546
f (7) = 0
Substituting values:
Avr = (0 - 316) / (7 - 5)
Avr = -158
Answer:
The average rate of change of f (t) from t = 5 seconds to t = 7 seconds is -158 feet per second.

Answer:
Population density = 1569 persons per mile.
Step-by-step explanation:
Population density is a measure of how crowded or uncrowded a specific piece of land in a geographical location or country is.
Given the following data;
Total population, N = 56,474 people
Area, A = 36 mi
To find the population density;
Population density = N/A
Population density = 56474/36
Population density = 1568.72 ≈ 1569 persons per mile.
Therefore, the population density of Valdosta is 1569 persons per mile.
