Let
C----------> the center of a circle
C (-4,5)
A-----------> a point on the circle
A (-9,10)
we know that
the distance between point A and point C is the radius of the circle
A (-9,10) C (-4,5)
d=√[(y2-y1)²+(x2-x1)²]--------> √[(5-10)²+(-4+9)²]
=√[(-5)²+(5)²]------> √[(25)+(25)]---------> √50
d=7.07 units
r=d--------> r=7.07 units
the equation of a circle is
(x+4)²+(y-5)²=50
see the attached figure
the answer is
the radius of a circle is 7.07 units
Answer:
It would be A. X= 125
Step-by-step explanation:
25*5=125
If the shop takes 15 percent off of $15 I would take 15 x .85 to get this 15 percent off giving Mindy $12.75 to spend. With a $12 pizza having 5 percent tax you take 12 x 1.05 too get a total of $12.06 as her total. This means in an even trade Mindy would lose 15 cents to the Pizza Shop
