We are given the expression of the equation of a circle that is x2 + y2 + 14x + 2y + 14 = 0. Using ocmpleting the squares: 
x2 + y2 + 14x + 2y + 14 = 0(x+7)^2 + (y+1) ^2 = -14 + 49 + 1(x+7)^2 + (y+1) ^2 = 36 center thus is at (-7,-1) and the radius is equal ot square root of 36 equal to 6.

A $4000 deposit in an account after 1 year with an APR of 3.6. How much is the balance after 1 year?
BaLLatris [955]
Hi!
Let's divide 4000 by 1000 to see what .1% would be: $4.
Now we multiply 4 by 36 to get 3.6% of 4000: $ 144
Add 4000 and 144 together:40144.
hope this helps!

The original cost of an item is $64, but you have to pay $78.08. What is the markup of the item ( and a percent)?
PIT_PIT [208]
$14.8 was the markup, And the price went up in 22%, how I got my answer!

I first found that adding $64+$14.8=$78.8, and for percentage, that took awhile. At first I thought that it would be 20% but upon further investigation I found that, 22% Of $64 is $14.8.

I hope this helps!

P.S. 20% of $64 is $12.8.
