Answer 1

Well, I'm rusty on these geometry problems, but to me it looks like the long side is 6.5, x is the short side, and the hypotenuse is the radius, which is half the diamater of 16.

So, we have pythagorean theorem which states x^2 + y^2 = hyp^2.

We know the hyp is 8 (radius).

We know the short side is x.

We know the long side is 6.5.

So, 6.5^2 + x^2 = 8^2.

Rearranging the equation: 8^2 - 6.5^2 = x^2

that is: 64 - 42.25 = x^2

that is: 21.75 = x^2

so x = sqrt(21.75) (but only the positive value)

x≈4.664 rounded to the nearest 10th, we get:

\(x \approx 4.7\)

Answer 15

. What is the standard form of the equation of the circle in the graph?

x2 + y2 = 3
(x + 3)2 + (y + 3)2 =9
(x + 3)2 + (y + 3)2 =3
x2 + y2 = 9

Answer 20

The equation of a circle is x^2 + y^2 = r^2. You see from the graph that your radius is 3, which is r. 3^2 = 9.
