What integer is less than -2 and greater than -3.5

The only integer that is less than -2 and greater than -3.5 is -3.

If you look at these on a number line, we need to look for numbers that come to the right of -3.5. The first one that we would come across is -3. This is also smaller than -2.

It's also important to note that -2 doesn't work because it says less than and not less than or equal to.

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.

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.
