Answer:
The answer to your question is (x - 4)² + (y - 5)² = 100
Step-by-step explanation:
Data
Point = (-2, -3)
Midpoint = (4, 5)
Process
1.- Find the length of the radius using the formula of the distance between two points.
dPM = 
x1 = -2 y1 = -3 x2 = 4 y2 = 5
dPM = 
dPM = 
dPM = 
dPM = 
dPM = 10
2.- Find the equation of the line
(x - h)² + (y - k)² = r²
h = 4
k = 5
r = 10
(x - 4)² + (y - 5)² = 10²
(x - 4)² + (y - 5)² = 100
First distribute the -4 and 3, then combine like terms
Answer:
cot(-270) = 0
Step-by-step explanation:
given cot ( -270)
In trigonometry function we will use cot ( -x) = -cotx
so cot (-270) = - cot270
<u>trigonometry table</u>
II quadrant I quadrant ( All positive)
sin θ 90+θ 90 -θ
<u> cosec</u> θ <u> 180-θ 360+θ</u>
third quadrant fourth quadrant
tan θ 180+θ cos θ 270+θ
cot θ 270 - θ sec θ 360-θ
Given
cot (-270) = -cot ( 270)
= - cot ( 180 + 90) (third quadrant above table)
= -cot 90 =0 ( cot θ positive in third quadrant
<u>Final answer</u>:-
cot(-270) =0
27/20 because you keep change flip
Answer:
The expression is equivalent to x^2-17x-60 would be (x - 20)(x + 3)
