Means-extremes property

Step-by-step explanation: A proportion is an equation that states two ratios are equal. For example, is an example of a proportion.

In the given proportion, a and d are called extremes and b and c are called means. The first property that I will be talking about states that the product of the extremes equals the product of the means.

This idea is called the means-extremes property.

So if , we know that ad = bc by the means-extremes property.

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
