(x-1)^2+(y+1)^2=0.25

Step-by-step explanation:

From the given graph it is clear that the center of the circle is (1,-1) and the circle passing through the point (0.5,-1).

So, radius of the circle is

$r=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$r=\sqrt{(0.5-1)^2+(-1-(-1))^2}$

$r=\sqrt{(-0.5)^2}$

$r=\sqrt{(0.5)^2}$

r=0.5

The radius of the circle is 0.5 units.

The standard form of a circle is

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

where, (h,k) is center and r is radius.

The center of given circle is (1,-1) and radius is 0.5. So, the equation of circle is

(x-(1))^2+(y-(-1))^2=(0.5)^2

(x-1)^2+(y+1)^2=0.25

Therefore, the required equation is (x-1)^2+(y+1)^2=0.25 .

Mathematics

To find the percentage of the discount first of all we will calculate the price discounted.
for that we will subtract the new price from the original price
225 - 90 = 135
Now to find the percentage discount we will use the following method of dividing the difference in both prices by original price multiply it with 100
135/225 x 100 = 60
This means that the percentage discount was 60% on this dress.
