The standard equation of a circle with centre (xc,yc) and radius R is given by
Substituting
centre (xc,yc) = (4,-3)
R=2.5
The equation is therefore
or
(x-4)^2+(y+3)^2=6.25

im not sure i just timed it by 2
Answer:
seconds
Step-by-step explanation:
When the ball hits the ground, its height will obviously be 0. Therefore, you can set up the equation the following way:
Plugging this into the quadratic equation, you get:
Since the time must be positive, it takes the ball seconds to hit the ground, or around 3.828. Hope this helps!
