Answer:
See below.
Step-by-step explanation:
Recall the equation for a circle:
, where (h,k) is the center and r is the radius.
We need to turn the given equation into the above format. We do this by completing the square.
First, group them:
For the first section, complete the square for 
:
Do the same for the second:
All together:
The center is (-9,-7).
The radius is 
The ratio is split as arena first, Cinnamon Bunnies second and One Route third.
Add the ratios together: 1 + 3 +8 = 12
Divide the total money by 12, then multiply that by the share One Route gets (8)
54,000 / 12 = 4,500
4,500 x 8 = 36,000
One Route get £36,000
The toy rocket hits the ground when h(t) = 0.
So, h(t) = 0 = -9t^2 + 81.
Solving the equation,
-9t^2 = -81
Dividing by -9
t^2 = 9
Taking the square root.
t = 3
The answer is 3 seconds.
The unit rate would be 11/2. Hope this helped.
