Answer:
<h2>a) center (2, -3)</h2><h2>b) radius r = 3</h2><h2>c) in the attachment</h2>
Step-by-step explanation:
The standard form of an equation of a circle:
![(x-h)^2+(y-k)^2=r^2](https://tex.z-dn.net/?f=%28x-h%29%5E2%2B%28y-k%29%5E2%3Dr%5E2)
(h, k) - center
r - radius
We have:
![(x-2)^2+(y+3)^2=9\\\\(x-2)^2+(y-(-3))^2=3^2](https://tex.z-dn.net/?f=%28x-2%29%5E2%2B%28y%2B3%29%5E2%3D9%5C%5C%5C%5C%28x-2%29%5E2%2B%28y-%28-3%29%29%5E2%3D3%5E2)
a) center (2, -3)
b) radius r = 3
c) in the attachment
D, he is moving at a constant spees
The solution of <span>0 = x2 − 5x − 36 is x = - 4 and x = 9

The angles of a triangle add to 180 degrees so the remaining angle must be 90°.
This triangle is half a square. It's one of the two tired triangles of trig, the other being half an equilateral triangle, 30°/60°/90°.
