Answer:
The correct option is A.
Step-by-step explanation:
The general exponential growth model is defined as
Where, a is initial value, r is growth rate and x is time.
The initial population of town is 9800 and growth rate is 2%. The population growth model is defined as
Put x=7 to find the estimated population after 7 years.
Therefore the correct option is A.
Perimeter is 2 times the length plus 2 times withe width.
Let X = the width, then the length would be 4x-4
Now you have :
2(x) + 2(4x-4) = 492
Simplify:
2x + 8x - 8 = 492
Combine like terms:
10x - 8 = 492
Add 8 to both sides:
10x = 500
Divide both sides by 10:
x = 500 / 10
x = 50
The width is 50 yards.
The length = 4(50) - 4 = 200-4 = 196 yards.
The maximum whole number of hours is 4 hours.
