Which equation describes the circle having center point (3,5) and radius r = 2
in standard form?

x^2 + y^2 - 6x  - 10y + 30 = 0.

Step-by-step explanation:

In factor form the general equation is:

(x - h)^2 + (y - k)^2 = r^2 where  (h, k) is the centre and r = the radius.

So here we have:

(x - 3)^2 + (y - 5)^2 = 4.

Converting to Standard Form:

= x^2 - 6x + 9 + y^2 - 10y + 25 = 4

x^2 + y^2 - 6x  - 10y + 9 + 25 - 4 = 0

x^2 + y^2 - 6x  - 10y + 30 = 0.

I believe the answer would be A, Chira will have more in her savings than Wyatt in every month.

Step-by-step explanation:

If you would look at the picture, you can see (IF YOU KNOW HOW TO READ A NUMBER LINE) that in 5 months Wyatt saved only $30.75. If you look at the graph where it had chiras savings account information, you can see that in 5 months she saves $48.50. You have to look at the graph and take hers where it has the point on [15] and then the point on [20] you subtract the difference between them both, and then you would just put 2 and 2 together so obviously Wyatt saves less being that he only saves $30.75 and Chira saves $48.50 every 5 months.

I hope this helped :)
