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.

Remember "rise over run." Rise means the vertical distance and run id the horizontal between the two points.

There is one solution.. for a pair of lines if the lines are perpendicular (these are) they only touch once
Answer:
5/8
Step-by-step explanation:
A. 2/3 × 4/5 × m = 1/3 B. 4/5 × 2/3 × m = 1/3
8/15 × m = 1/3 8/ 15 × m = 1/3
m = 1/3 ÷ 8/15 m = 1/3 ÷ 8/15
m = 1/3 ×15/8 m = 1/3 × 15/8
m = 5/8 m = 5/8
C. 2/3 × 4/5 = 1/3 ÷ m
8/15 = 1/3 × 1/m
8/15 = 1/3m cross multiply
(3m) × (8) = 15
24m = 15
m = 15/24
m= 5/8
