Consider the right triangle with hypotenuse r , horizontal leg 5, vertical y leg, with angle ∅ opposite y. How can we view r as depending on y only? How can we view r as depending on ∅ only? Explain by using appropriate relationships in the triangle and writing r both as a function of y only and as a function of ∅ only.

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
