X2 + y2 = 29
Center of the circle
x=0 and y=0
Therefore the slope of the line perpendicular to the tangent line
(y2-y1) / (x2-x1)
(5-0) / (2-0)
5/2
so the slope of the tangent
-2/5
General equation for the line
y = mx + c
if the line satisfies with the point (2,5)
5 = 2m + c
m = -2/5
5 = 2 * (-2/5) + c
c = 5 + (4/5)
c = 29/5
Therefore the equation of the line
y = mx + c
y = (-2/5) m + 29/5
Retail Price= $40
Price after 20% discount
20/100 x 40 = $8
40-8= $32 after discount
tax paid on $32 shirt = 5/100 x32 = $1.6
she paid $32+$1.6= $33.6
Answer:
If two lines intersect, then there is one plane
that contain(s) them
Step-by-step explanation:
According to the plane-line postulate, if two points lie in a plane, the line containing them lies on the plane.According to the line intersecting theorem, if two lines intersect, then exactly one plane contains both lines.This should be the line-intersecting theorem.
