Algebra 2 H Areas and Riemann Sum

It takes 50 minutes for Joe to notice that his cola bottling machine has sprung a leak. Joe is able to sop the leak in 10 minutes. The graph shows the rate at which cola leaks from the machine as a function of time. How many cola does Joe lose in this bottling disaster?

A snowstorm lasts 18 hours. The graph below shows the rate of snowfall as a function of time. What is the total snowfall?

Approximate the area between the x-axis and g(x) from x=-1 to x=5 using the right Riemann sum with 3 unequal subdivisions.

Approximate the area between g(x) and the x-axis from x=2 and x=6 using a left Riemann sum with 4 equal subdivisions.

Approximate the area between the x-axis and $g\left(x\right)=2^x$  from x=-2 to x=2 using a right Riemann sum with 4 equal subdivision.
