Option A:
Solution:
Given data:
Center of the circle is (5, 3).
Radius of the circle = 4
To find the equation of the circle:
The general form of the equation of a circle in centre-radius format is
where (h, k) is the centre of the circle and r is the radius of the circle.
Substitute the given values in the equation of a circle formula:
The equation of the given circle is .
Hence Option A is the correct answer.
Answer:
4
Step-by-step explanation:
Answer:
4/9
Step-by-step explanation:
I can't see pictures, but to find the area of a triangle, you multiply the dimensions, as you would a rectangle, but divide the area by 2.
For example, the dimensions of a triangle are 4 and 6.
Multiply the two.
4x6=24.
But don't stop there. Divide 24 by 2.
24/2=12.
So the area of the example triangle is 12.

Step-by-step explanation:
equation of a line = y-y1=m(x-x1)
but we have to find the slope
so slope=<u>y</u><u>2</u><u>-</u><u>y</u><u>1</u><u> </u><u> </u><u> </u><u> </u> = -<u>7-5</u>
x2-x1. 3--3
<u>-12</u>
6
<u>-2</u>
1. =-2
y-5=-2(x-3)
y-5=-2x+6
y=-2x+6-5
y=2x+1
