Answer:
The correct answer is D.
Step-by-step explanation:
Given:
General equation of second degree
x² + y² + 14 x + 2 y + 14 = 0
We must transform given equation to the canonical form from which we will read requested data.
The canonical form of the circle equation is:
(x - p)² + (y - q)² = r²
Where p and q are the coordinates of the center of the circle and r are radius. (p,q) = (x,y)
x² + 2 · x ·7 + 7² - 7² + y² + 2 · y · 1 + 1 - 1 + 14 = (x+7)² + (y+1) - 49 - 1 + 14 = 0
(x + 7)² + (y + 1)² = 36
We see that p = - 7 , q = - 1 and r = 6

Answer:
7/8 Acre
First, convert the mixed number 1 3/4 into an improper fraction. This will be 7/4. Now, divide this by two because the year is half over. Doing this you get 7/8.
Answer:
10.6% decrease
Step-by-step explanation:
The percentage change in a quantity is computed using ...
percentage change = ((new value)/(old value) -1) × 100%
= (2.10/2.35 -1) × 100%
= (0.8936 -1) × 100%
= -.1064 × 100%
= -10.64%
The percentage decrease was about 10.6%.
5.9%
Let's see what percentage of 2.55 is 2.40
or $2.40 = x% of $2.55
2.40 = (x/100)(2.55)
x = 2.40(100)/2.55
x = 240/2.55
x = 94.1%
$2.40 is 94.1% of $2.55
The decrease is from 100% to 94.1%
100-94.1 = 5.9% decrease in price
