Arrange these functions from the greatest to the least value based on the average rate of change in the specified interval.
f(x) = x2 + 3x
interval: (-2, 3]
f(x) = 3x - 8
interval: [4, 5]
f(x) = x2 - 2x
interval: (-3, 4]
f(x)=x2.5
interval: [1, 11

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml

im pretty sure its b
