Answer:

Step-by-step explanation:
Given
Regression Equation:

Required
Determine the slope of the regression line
The equation of regression is of the form

Where b represents the slope;
Compare
to the given equation

We have that:




Hence; the slope is:

Answer- 42646.50 pounds
Area of flat surface = Area of rectangle + area of triangle
= 12.9*25 + 1/2* 7.2* 25
= 162.5 feet^2
Force exerted by wind =0 .004 * Area * velocity^2
= 42646.50 pounds
