Timothy purchased a computer for $1,000. The value of the computer depreciates by 20% every year. This situation represents

The rate of growth or decay, r, is equal to

year.

So the value of the computer each year is

% of the value in the previous

It will take

years for the value of the computer to reach $512.

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 answer is ! ?

central angle of a triangle has the same measure as its intercepted arc.
