The bottom of a ladder rests on the ground and the top of the ladder rests against a wall. The ladder forms a 66° angle with the ground and the top of the ladder is positioned 11 meters up the wall. Which is the exact measure of the ladder in meters? a) 11/sin(66°) meters
b) sin(66°)/11 meters
c) sin(66°/11) meters
d) sin(11°/66) meters

answer: i oofed

step-by-step explanation:

oofed=wow

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.

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:
