Answer:
<h3> (x-8)²+(y-3)² = 81</h3>
Step-by-step explanation:
The general equation of a circle is expressed as;
(x-a)²+(y-b)² = r² where;
(a, b) is the centre of the circle
r is the radius
Given the centre (8, 3) and the radius of 9, the equation of the circle will be;
(x-a)²+(y-b)² = r²
(x-8)²+(y-3)² = 9²
(x-8)²+(y-3)² = 81
hence the required equation is (x-8)²+(y-3)² = 81

Answer:
annual growth rate m = 637.5 people / year
Step-by-step explanation:
Solution:-
- The scatter plot displaying the city's population was modeled by a linear equation of the form:
y = m*x + c
Where, m and c are constants.
- The scatter plot displayed the following relation of the city's population (p):
p = 637.5*t + 198,368.1
Where, p : The population in t years after after 1990
t : The number of years passed since 1990.
- The slope of the graph "m = 637.5" denotes the rate of change of dependent variable with respect ot independent variable:
dp / dt = m = 637.5
- So the rate of change of population per unit time t since 1990 has been constant with a an annual growth rate m = 637.5 people / year
A) 68.8
b) 5.9
c) 634.9
d) 90.0
