dude, would you have the answers to this application type Qs?

Ill try the fanning blade question but I cant guarantee you my answers will be correct....

a.) Simultaneous Equation, try and grab 3 points from the graph and substitute it to the form .

(0,8)(4,0)(2,6)




solve algebraically to get a mathematical model for the fan blade..

b.) ,

the crucial part to this question is not forgetting to restrict the domain!!! as it is a realist question.

c.) just try and substitute in points that satisfy the domain restriction in the equation to show that the mathematical model in part b.) is correct..

d.) sorry, I dont really know how to this question.....



hope this helped...
