The first thing we must do for this case is to define variables.
n = number of 5k races covered
f = end time.
We have the following equation:
f = -1.2n + 38.1
We note that the slope of the line is:
m = -1.2 minutes per race
Therefore, the time decreases 1.2 minutes when the number of races increases n.
Answer:
The model predicts that for each additional race to runner has run, the finishing time decreases by about 1.2 minutes

p(x)= -
+ 800x - 1599
given x = a is a zero of a polynomial p (x) then
(x - a) is a factor of the polynomial
complex zeros occur in conjugate pairs
5 + 4i is a zero hence 5 - 4i is a zero
factors are (x - 3),(x + 13),(x - (5 + 4i) and (x - (5 - 4i)
The polynomial is the product of it's factors
p(x) = (x - 3)(x + 13)(x - (5 + 4i)(x - (5 - 4i)
expanding the factors
p(x) = ( + 10x - 39)(
- 10x + 41)
= -
+ 800x - 1599
