1. Quadratic y=x^2
2. Linear y=X+7
3. Exp. Y= 1 times 2^x
4. Linear Y=4x
5. Linear Y= -5x+1
<span>it is 3000000000 because 1 gigameter is 1000000000 so 3 is 3000000000</span>
=ligma baalls so that I can tape this d to your fore head so you can cd’s nuts
Since the standard form of the circle is:
(x-h)^2+(y-k)^2=r^2, and (h,k)=(0,0) and r=10 so we have:
x^2+y^2=100 Looking at the points you have:
(√10, 0) does not work as (√10)^2+0^2=10+0=10
(0, 2√5) does not work as 0^2+(2√5)^2=0+20=20
(5√2, 5√2) works as (5√2)^2+(5√2)^2=50+50=100
