Answer:
(x -2)² +(y +4)² = 34
Step-by-step explanation:
The center of the circle is the midpoint of the line segment:
S = (J +K)/2 = ((-1, -9) +(5, 1))/2 = (4, -8)/2 = (2, -4)
The radius of the circle is the distance between the center and either end point. We want the square of the radius for our formula.
r² = (5 -2)² +(1 -(-4))² = 9 +25 = 34
The equation of a circle with center (h, k) and radius r is ...
(x -h)² +(y -k)² = r²
Using the numbers we have found, the equation for circle S is ...
(x -2)² +(y +4)² = 34
Circumference = 2*pi*radius. Pi = 3. 2 * 3 = 6. Find r: 96/6 = 16.
To start off you need to add three to -5
Then you were left with
2a=(-2)
Then you need to divide two to both sides
2a=(-2)
/2 /2
Then you were left with a equals one
A=1
and that is your Final answer
Answer:
it would be 53
Step-by-step explanation:
(Subtract 3.99 on both sides)
(Divide 0.99 to isolate x)
21.01/ 0.99 is 21.222 bar, so round it to the nearest ones place, which is 21.
