What is the radius of a circle whose equation is X^2 plus Y^2 -10X +6 X +18=0?

frosja888 [35]

ANSWER

The radius is 4

EXPLANATION

The given equation is:

${x}^{2} + {y}^{2} - 10y + 6x + 18 = 0$

We complete the square to get the expression in standard form:

${x}^{2} + 6x + {y}^{2} - 10y + 18 = 0$

${x}^{2} + 6x + 9 + {y}^{2} - 10y + 25 = - 18 + 9 + 25$

We factor using perfect squares to get:

${(x + 3)}^{2} + {(y - 5)}^{2} = 16$

This implies that,

${(x + 3)}^{2} + {(y - 5)}^{2} = {4}^{2}$

Comparing to

${(x - h)}^{2} + {(y - k)}^{2} = {r}^{2}$

The radius is r=4

What is the range of the data? 99.7, 101.8, 103.6,98.6, 100.2, 102.9

erik [133]

Answer:

5.0

Step-by-step explanation:

The data in order looks like so:

98.6, 99.7, 100.2, 101.8, 102.9, 103.6

Take the greatest value and subtract it from the least value to get the range of the data:

103.6-98.6=5

5 is your answer

Hope this helps!
