Answer:
Area of regular pentagon is 238.95 square inches.
Step-by-step explanation:
Given a regular pentagon with side length of 11.8 inches and dotted line from center to middle of side of 8.1 inches.
we know a regular polygon divides into 5 congruent triangles.
Side of pentagon i.e base of one triangle is 11.8 inches.
Also, distance from center to middle of side which is height of triangle is 8.1 inches.
Area of 1 triangle=
=
= 47.79 sq inches.
Area of regular pentagon=area of 5 congruent triangles= =238.95 sq inches.
Answer:
The population in 2039 would be;
<em>Note</em><em>: this value can be confirmed by using the spreadsheet to extrapolate values.</em>
Explanation:
Given that the population in 2019 was;
And the population in 2020 was;
The population growth can be modeled with a linear equation;
The slope m is given as;
And b would be the value of y at x=0.
where x is the number of years after 2019;
the model can then be written as;
At year 2039, x would be;
substituting the value of x into the model;
Therefore, the population in 2039 would be;
<em>Note: this value can be confirmed by using the spreadsheet to extrapolate values.</em>
