Answer:
No. Dividing by 0 is not rational, no number works.
Answer:
120 people/sq. mile
Step-by-step explanation:
Population Density is the concept of how "crowdy" a place is. The more the population density, the more crowded that place is.
The population density is found by dividing the "number of people" by the "land area" (in sq mile or sq km).
Here, it is given there are 600 million people, so
Number of People = 600,000,000
And, the land area is given as 5 million square miles, so
Land Area = 5,000,000 sq. miles
Hence,
Population Density = 600,000,000/5,000,000 = 120 people/sq. mile
Answer:
First one: C. Second One:C.
Step-by-step explanation:
Kate purchased a car for $23,000. It will depreciate by a rate of 12% a year. What is the value of the car in 4 years?
a) $13,935.76
b) $12,874.57
c) $13,792.99
To solve this this is an exponential function. The price started at $23,000 and depreciates at 12% so the equation is f(x) = (23,0000)(1-0.12)^4. When calculated results with 13792.99328 which is C.
A rare coin is currently worth $450. The value of the coin increases 4% each year. Determine the value of the coin after 7 years.
a) $613.98
b) $546.78
c) $592.17
To solve this this is also an exponential function. The price started at $450 and the coin increases 4% each year so the equation is f(x) = (450)(1+0.04)^7. When calculated results with 592.169300656 which is c.
