$$\int_{0}^{40}$$c(t) dt      is the total calories burned during the workout......

$$\int_{0}^{10}$$ t-.05t^2+15  dt     +     $$\int_{10}^{30}$$ 20   dt   +       $$\int_{30}^{40}$$3t-.05t^2-25  dt     = total calories burned

First part:   1/2 t^2 - .05/3 t^3 + 15 t       From 0 to 10 =    50 - 16.67 + 150  =183.33 cal

Second part:   20 t      from 10 to 30 =      600 - 200 = 400 cal

Third part:   Think you can do this one?
