Calculate distance FC
FC is calculated as:
Where
Considering 
, we have:
--- Pythagoras theorem
Where
and
So:
Take square roots of both sides
So:
Considering 
, we have:
--- Pythagoras theorem
Where:
and 
So, we have:
Take square roots of both sides
So;
Recall that:
Answer:
you're multiplying -1 times n and -8
Step-by-step explanation:
once you distribute it, it would be -2=-n+8
The best way to solve this problem is to graph all variables, velocity being the dependent variable (y-axis) and time being the independent variable (x-axis) . Since we are given two points for the two variables, we use the point-slope formula to get the slope which happens to be -1. We then use the standard form y = mx + b and substitute m with -1. Next we want to find b, we will again use the point slope formula now knowing m to be -1. we chose point 0 for time(x-axis) and at zero, we obtain a value of your b which happens to be +19. A line graph would better visualize my point. Cheers!
