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>
Answer:
24 kilometers
Step-by-step explanation:
1.2 kilometers per minute; 12 kilometers
Step-by-step explanation:
We know that 60 minutes makes 1 hour.
Therefore, to convert the speed to kilometers per minute, we simply divide 72 kilometers per hour by 60 minutes:
72 / 60 = 1.2 kilometers per minute.
Distance is given as speed multiplied by time.
Therefore, in 10 mins, the car travels:
1.2 * 20 = 24 kilometers.
(a) True
Because the sum of the angles in a triangle is 180°
Obtuse angle = angle greater than 90°.
180° - Obtuse angle = less than 90°
So there cannot be another obtuse angles, therefore both the other angles will be acute.
