Suppose the depth of water in the lake at time t is given by h(t) = 5 -1/3t What is the average depth of the lake over the first 12 months?
Again, suppose the depth of water in the lake at time t (where t is measured in months\) is given by h(t) = 5
t. What is the average depth of the lake over the first 12 months?
O a. 2
O b, 2,5
Oc 3
O d. 10
Note, In fact, the integral formula form the video is how we define the average value of a function in general: If f(r) is continuous on [a, b]m then the average value of f(r) on la, b) is
1
fave =
b- aJ f(z) dz.
