Q3.) Write the standard form of the equation of the circle with the given center and radius.
vlada-n [284]
The center has coordinates h = -2, k = 5.  The radius is sqrt(6).  The equation for a circle is as follows: (x-h)^2+(y-k)^2=r^2.  Filling in using our given info we have (x-(-2))^2+(y-5)^2=( \sqrt{6})^2.  Simplifying that down we have an equation of (x+2)^2+(y-5)^2=6.  There you go!

Create a system of equations to solve
antiseptic1488 [7]
R=2K which equals 2R=4K
4(R=K+8) or 4R=4K+32

Subtract first equation from second equation.
2R=32 so R=16

Plug into first equation
16=2K so K=8

Now plug both into second equation to check
4R-4K=4(R-K)=4(8)=32 it works

So Roberto is 16 and Katie is 8
(In 4 years R would be 20 and K would be 12 which has a difference of 8)
