Can someone give a simple explanation of how to find the rate of change?

Divide the output value by the change in the input value.

Step-by-step explanation:

rate of change=change in y change in x=change in distance change in time=160−804−2=802=401. The rate of change is 401 or 40. hope you find it

useful.

it will V -U/T. this is the formula of acceleration

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

step-by-step explanation:

i am only able to answer the first part. i am not sure about the second part. sorry
