A certain circle can be represented by the following equation. x^2+y^2+18x+14y+105=0 What is the center of the circle? What is t
Gre4nikov [31]

Answer:

See below.

Step-by-step explanation:

Recall the equation for a circle:

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

We need to turn the given equation into the above format. We do this by completing the square.

First, group them:

(x^2+18x)+(y^2+14y)=-105

For the first section, complete the square for x^2+18x:

x^2+18x+81-81

(x+9)^2-81

Do the same for the second:

y^2+14y

y^2+14y+49-49

(y+7)^2-49

All together:

((x+9)^2-81)+((y+7)^2-49)=-105

(x+9)^2+(y+7)^2-130=-105

(x+9)^2+(y+7)^2=25

The center is (-9,-7).

The radius is \sqrt{25}=5

Estimate 63.730+ 32.73 by first rounding each number to the nearest whole number​
Shalnov [3]

Answer:

97

Step-by-step explanation:

Round each number to the nearest whole number (the digit directly left to the decimal point.) Note that if the digit to the right of the decimal point is 5 or greater, round up; if it is 4 or lower, round down:

63.730 rounded to the nearest one is 64.

32.73 rounded to the nearest one is 33.

Add:

64 + 33 = 97

97 is your answer.
