Water is pouring into a container at a rate given by ri = t^3(gallons/hour), and water is pouring out of the same container at a rate given by ro(t) = e^t(gallons/hour). if there are 100 gallons of water at time t = 0, how many gallons of water will be in the container at t=4 hours?

Radii ok and nl are perpendicular to om because of the radius-tangent theorem. by definition of perpendicular, angles kom and lnm are right angles. this means that triangles kom and lnm are right triangles. angle lmn is common to both right triangles, so by the triangles kom and lnm are similar.
