Answer:
Centre = (-2,7) B
radius = 6
Step-by-step explanation:
The general formula for finding the equation of a circle is expressed as shown:
(x-h)²+(y-k)² = r² where (a,b) is the centre and r is the radius of the circle
Given the equation of the circle C in question (x+2)²+(y−7)²=36. We will compare the given equation to the general equation.
On comparison;
-h = 2
h = -2
-k = -7
k = 7
r² = 36
r = √36
r = ±6
From the answers gotten, it can be inferred that the centre of the circle (h,k) is (-2,7) and the radius of the circle is 6.
Radius of a circle cannot be a negative value so we will ignore the negative value of 6.
Compounded quarterly means that one quarter of the interest is added to the account each quarter
one quarter of 6% is 1.5%
x = 7201 (1 + .06/4)^2 ___ .06/4 is the interest per compounding , and 2 is the number of compoundings
2x -3y = 12;
x + 3y = 6;
__________(+)
3x = 18;
x = 18÷3;
x = 6;
Then, 3y = 6 - 6;
3y = 0;
y = 0÷3;
y = 0;
