Find an equation of the circle that has center (-1,1 ) and passes through (1,-6)
Ivahew [28]

Answer:

(x+1)^2+(y-1)^2=53

Step-by-step explanation:

The standard form for the equation of a circle is (x-h)^2+(y-k)^2=r^2, where h is the x coordinate of the center, k is the y coordinate, and r is the radius. To find the radius of this circle, we can simply find the distance from the center to any of the points on its circumference. Using the distance formula, you know that the distance from (-1,1) to (1,-6) is:

\sqrt{(1-(-1))^2+(1-(-6))^2}=\sqrt{2^2+7^2}=\sqrt{4+49}=\sqrt{53}

Therefore, the equation of this circle is:

(x+1)^2+(y-1)^2=53

Hope this helps!

Jan has a recipe for bread . She uses 2/3 of flour and 1/3 cup of chopped onion. Which ingredient does she use moré ?
ElenaW [278]
<span>Jan has recipe for bread. She uses 2/3 of flour and 1/3 cup of chopped onion. Let us find out which of the 2 ingredients did Jan used more.
We have the following given data:
=> 2/3 cup of flour
=> 1/3 cup of chopped onion.
Let’s first convert this to decimal to know which ingredients is used more.
=> 2/3 = 2 / 3 = 0.67
=> 1/3 = 1 / 3 = 0.33
Thus, more cups of flour is used compare to the chopped onions.</span>
