The sun produces 3.9 ⋅ 10^33 ergs of radiant energy per second. How many ergs of radiant energy does the sun produce in 1.55 ⋅ 10^7 seconds? Please help even if you are in middle school and please show the work.

radius=5, centre=(-1,-2)

Step-by-step explanation:

You need to complete the square for both x and y.

breaking the equation up we find that: in completed square form = which simplifies to . Remember that you complete the square by halving the "b" value and then squaring it. 2/2 squared=1. Also, the one that you add to complete the square must be added to the other side of the equation to get 20+1.

Now onto the y value in completed square form =. The 4 that you add to get it into the quadratic form must be added on other side of the equal sign to get 20+1+4.

the final equation is
