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
Answer:
<h2><u>111°</u></h2>
Step-by-step explanation:
Hi,
So lets answer this question;
Here we know that:
69° + z = 180° [Straight angle or Supplementary angle]
⇒ z = 180° - 69°
= <u>111°</u>
Answer:
you're all good !!
Step-by-step explanation:
1 bar is $1.50 because $3 divide 2 is 1.50
c= 1.50b
1= $1.50
2= $3
3= $4.50
4= $6
Answer:
Step-by-step explanation:
5 1/3 round to 5 because 1/3 = 0.333 less than 0.5
3 7/9 round to 4 because 7/9 is over 0.5
5+4=9
