Determine the center and radius of the following circle equation: x^2+y^2+20x+8y+35=0

natta225 [31]

Answer:

center: (-10,-4)

radius: 9

Step-by-step explanation:

Let's start off by moving the 35 to the other side and grouping the x and y terms we have

(x²+20x)+(y²+8y)= -35

Next we take the term with the x coeficcent, divide it by 2, and square it

for the x we would do (20/2)²=100

and make sure we add that to the 35

(x²+20x+100)+(y²+8y+16)= -35+100+16

next factor everythign to get

(x+10)²+(y+4)²=81

therefore the center is (-10,-4)

and the radius is √81 or 9

DedPeter [7]

Answer:

2628.48 cubic inches

Step-by-step explanation:

The inflatable raft has 4500 cubic inches of air inside it when fully inflated.

The inflatable raft loses air at a rate of a decrease 6.5% each day.

Now, we have to calculate the volume of air that will be left in the raft after 8 days.

Therefore, the volume of air left in the raft after 8 days will be $4500[1-\frac{6.5}{100} ]^{8} =2628.48$ cubic inches. (Answer)
