The rate at which sand is poured into a bag is modeled by the function r given by r(t)=15t−2t2, where r(t) is measured in milliliters per second and t is measured in seconds after the sand begins pouring. How many milliliters of sand accumulate in the bag from time t=0 to time t=2 ?

35 mililiters

Step-by-step explanation:

Given

Required

Accumulated amount from t = 0 to 2

This implies that, we substitute the values of t from 0 to 2 in the function

The accumulated sand (r) is:

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

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

are ya tryin to ask something or is this a statement
