Chapter 11: Q. 35 (page 1082)

In the following exercises, ⓐ find the center and radius, then ⓑ graph each circle.
${(x - 1.5)}^{2} + {(y + 2.5)}^{2} = 0.25$

Short Answer

Expert verified

(a) Center of the circle ${(x - 1.5)}^{2} + {(y + 2.5)}^{2} = 0.25$ is $(1.5, - 2.5)$ and radius is $0.5$

(b) graph of the circle is

Step by step solution

Step 1. given data

The given equation of the circle is

${(x - 1.5)}^{2} + {(y + 2.5)}^{2} = 0.25$

Step 2. Part (a)

Compare the equation of the circle with the standard equation of the circle

${(x - 1.5)}^{2} + {(y + 2.5)}^{2} = 0.25 {(x - 1.5)}^{2} + {(y - (- 2.5))}^{2} = {(0.5)}^{2} {(x - h)}^{2} + {(y - k)}^{2} = r^{2}$

so center $(h, k) = (1.5, - 2.5)$

and radius $r = 0.5$

Step 3. Part (b)

Plot the circle of center $(1.5, - 2.5)$ and radius $0.5$
