(5.5) A weather balloon is being filled at a rate of r(t) = 18(1 + 2t) 2 liters per second, starting with a volume of 0 liters at time t = 0. What is the volume of the balloon after 1 minute?

78 liters

Step-by-step explanation:

The rate of change in volume is given by:

Integrating the expression above from t = 0 to t = 1 minute, gives us the final volume of the balloon after a minute:

The volume of the balloon after 1 minute is 78 liters.

13.33%

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%
