4. A Ferris wheel is moving around in a circle in a counterclockwise direction. It has a radius of 50 feet and it takes 24 seconds to go around the circle once. Its lowest point is 5 feet off the ground. A passenger is at the "3 - o'clock” position when t = 0. Write an equation that represents the height of the chair in terms of time.

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.

d. corresponding side lengths in similar triangles are proportional in length.

step-by-step explanation:

you meant circumference well the answer is:

17.27876 miles

area is 23.7583

the radius is 2.75 miles

hope this hmu if needed.

16 is the coefficient

hope this
