5. Find the center and radius of the circle with the given equation.
leonid [27]

Answer:

A

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

(x + 4)² + (y - 1)² = 25 ← is in standard form

with centre = (- 4, 1 ) and r = \sqrt{25} = 5 → A

If the area of Bianca’s rectangular backyard patio is represented by the expression x2 – 18x + 81, and the length of the patio i
Verizon [17]

<u>1) </u> width=x-9

2) Rectangular shape is square shape patio !

<u>Step-by-step explanation:</u>

Here we have ,  the area of Bianca’s rectangular backyard patio is represented by the expression x2 – 18x + 81, and the length of the patio is represented by the expression x − 9: We need to find

1. what is the expression for the width of the patio? Explain and show all work.

We know that area of rectangle = Length(width)

⇒ x^2-18x+81=(x-9)(width)

Factorizing RHS:

⇒ x^2-9x-9x+81=(x-9)(width)

⇒ x(x-9)-9(x-9)=(x-9)(width)

⇒ (x-9)(x-9)=(x-9)(width)

⇒ width=x-9

2. what special rectangular shape is the patio?

Now , we see that

Length = x-9\\Width=x-9

A rectangle whose length & width are equal is known as a square ! Hence ,  Rectangular shape is square shape patio !
