Answer:
(x + 4)² + (y + 5)² = 73
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) = (- 4, - 5), thus
(x - (- 4))² + (y - (- 5))² = r², that is
(x + 4)² + (y + 5)² = r²
The radius is the distance from the centre to a point on the circle.
Calculate r using the distance formula
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 4, - 5) and (x₂, y₂ ) = (4, - 2)
r =
=
= = ⇒ r² = 73, thus
(x + 4)² + (y + 5)² = 73 ← equation of circle
Answer:
11
Step-by-step explanation:
Focus on the product of a number and three part first
3×X=?
next it says 18 is 15 less than the product so the product is equal to
18+15=33
now Rewrite the initial equation with the product
3×X=33
now divide by three on both sides to isolate the X , that will result in
X=11
good luck!!! I believe in you!!!
Answer:
ok so you say I don't know for 10000000000 year's the end. :)
Answer:
I think so, but don't lose sight
The Y^2 because 4 to the power of 2 would give you 4x4 which gives you 16
