Answer:
16= (x-4)^2 +(y+9)^2
Step-by-step explanation:
hey! The formula for the equation of a circle is r^2= (x-h)^2 + (y-k)^2
r= the radius (in your case you have the diameter so you do not need to square it)
(h,k)= is the center coordinates, so your center coordinate would be (4, -9). You now have your h (h=4) and your k (k=-9) so you can plug it in the formula! :)

Answer:
Step-by-step explanation:
The rate of change in any function is the slope of the line between 2 points. Our points are t = 2 and t = 5. But we know that the slope formula also involves the h's for each of those t's. We need to find them first. The slope formula is
, but for us it will look like this (fittted to our needs):
. So we need to find those h's.
when t = 2, plug in a 2 for t and solve for h.
Therefore,
and
h(2) = 32 and in coordinate form, (2, 32).
When t = 5, plug in a 5 for t and solve for h.
Therefore,
and
h(5) = 14 and in coordinate form, (5, 14). Now we can plug into our slope formula:
, choice B.
The rate of change is -6 which, in words, means that the ball fell 6 feet every 1 second it fell.
