What is the simplified form of the equation fraction 4 over 5 n minus fraction 1 over 5 equals fraction 2 over 5 n
liubo4ka [24]
4/5n – 1/5 = 2/5n
Add 1/5 to both sides
4/5n = 2/5n + 1/5
Subtract 2/5n from both sides
2/5n = 1/5
Divide both sides by 2/5

n = 1/2

Suppose the population of a town is 9,800 and is growing 2% each year. a. Write an equation to model the population growth. b. P
tiny-mole [99]

Answer:

The correct option is A.

Step-by-step explanation:

The general exponential growth model is defined as

f(x)=a(1+r)^x

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

f(x)=9800(1+\frac{2}{100})^x

f(x)=9800(1+0.02)^x

f(x)=9800(1.02)^x

Put x=7 to find the estimated population after 7 years.

f(x)=9800(1.02)^7

f(x)=11257.119543\approx 11257

Therefore the correct option is A.
