349.304347826097 that is the answer
Ill show you step by step.
This is what the equation should look like
Y=Initial value(1+/- Increasing or Decreasing value)^2 Which stands for time

So you need to do 1.0525 to the 2nd power Which equals 1.10775625
So now you need to do 15,000(1.10775625)

Which equals <span>16616 rounding to the nearest Ones
16616.3 rounding to the nearest tenth</span>
The answer to the question
Answer:
d(t)=-10t-520
Step-by-step explanation:
First you have to find the gradient (m) using the formula 
using the two points you have been given: 1(3,-550) and 2(8,-600)
so you substitute these points into the equation 
m=-10
Now that you have found the m-value you need to find the b-value by using one of the points you already have, I will use Point 2 (8,-600), and substitute it into the equation and solve
d(t)=-10t+b
-600=-10*8+b
-600=-80+b
-520=b
Therefore, the equation is d(t)=-10t-520
