Answer:
(x - 3)² + (y + 5)² = 10
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, - 5 ) , then
(x - 3)² + (y - (- 5) )² = r² , that is
(x - 3)² + (y + 5)² = r²
r is the distance from the centre to a point on the line
Calculate r using the distance formula
r = 
with (x₁, y₁ ) = (3, - 5) and (x₂, y₂ ) = (6, - 4)
r = 
= 
= 
= 
⇒ r² = ( )² = 10
(x - 3)² + (y + 5)² = 10 ← equation of circle
9 because if you add 6x and 4x it makes 10x. if youre finding a 90 degree angle then it has to equal 90. 10 x 9 = 90.
Answer:
What is the question tell me clearly.
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
A is for sure wrong because we can see the distribution of the data showing us that the center is at 8. B is also wrong because the spread is only from 6.5 even though the table goes from 5. C would be correct because its symmetrical in shape.
