The population size after 6 years and after 8 years are 147 and 169 population respectively
<h3>Exponential functions</h3>
The standard exponential function is expressed as y = ab^x
where
a is the base
x is the exponent
Given the function that represents the population size P (t) of the species as shown;
For the population size after 6 years
For the population after 8 years
Hence the population size after 6 years and after 8 years are 147 and 169 population respectively

Answer:
C. 40π cm²
Explanation:
• The central angle of the sector = 225 degrees
,
• The radius of the sector = 8cm
For a sector of radius r and central angle θ, we calculate the area using the formula below:
Substituting the given values, we have:
The area of the sector is 40π cm².
Based on the information given, it should be noted that the fraction to represent the distance will be 1 3/20 miles.

How to convert decimal to fractions.</h3>
From the information given, it was stated that Marcy lives 1.15 miles away from her grandmother.
Therefore, the fraction that represents the distance between Marcy's house and her grandmother's will be:
= 1 + 15/100
= 1 + 3/20
= 1 3/20
Therefore, the fraction is 1 3/20.
