Answer:
(x - 3)² + (y + 4)² = 49
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + *y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (3, - 4) and r = 7 , then
(x - 3)² + (y - (- 4) )² = 7² , that is
(x - 3)² + (y + 4)² = 49 ← equation of circle
P=68
P=2L+2(9)
-----------------
Therefore:
2L+2(9)=68
2L+18=68
2L=68-18
2L=50
L=50/2
L=25
---------------
So the length is equal to <u>25 inches</u>.
Answer:
-1
Step-by-step explanation:
We can find the slope given two points
m = (y2-y1)/(x2-x1)
=( -4 -8)/(10--2)
= (-12)/(10+2)
-12/12
-1
1/4 x 4p
Four (4) is equal to (=) 4/1, because 4 divided by 1 is still just 4.
=1/4 x 4/1p
The 1/4 and the 4/1 cancel each other out because we multiply the numerators and denominators to just get 4/4 which can be simplified to the number 1.
=1 x p
= p
First, you subtract 9 from both sides to get x/5=-5. Then, multiply by five on both sides to get x=-25.
