Answer:
Your missing a number and your answer is 12
Step-by-step explanation:
The 1, 2, 3 I’m not sure bout the 4th one
If 3 ice cream cones cost 8.25 how much do 2 ice cream cones cost?
1 cone cost
8.25 : 3 = 2.75
2 cones cost
2.75 * 2 = 5.5
or
(8.25 : 3) * 2 = 5.5
The center is at origin O(0,0).
If it contains the point, P(-8,6), then the radius r is, by Pythagoras theorem,
r=sqrt((-8)^2+6^2)=10
The general equation of a circle at centre (xc,yc) with radius r is given by
(x-xc)^2+(y-yc)^2=r^2
Substituting r=10, (xc,yc)=(0,0)
the resulting equation is therefore
(x-0)^2+(y-0)^2=10^2
or simply
x^2+y^2=100
You need to put the equations?
