Karen is replacing an old water storage tank on her farm with two smaller tanks that together have the same storage capacity as the old tank. The capacity of the old tank, in gallons, can be represented by the function T(x) = 250x + 4.5, where x is the storage capacity of a bucket, in gallons, that Karen uses on the farm. The capacity, in gallons, of one of the new, smaller tanks can be represented by the function S(x) = 150x + 3.2. The function which best describes C(x), the capacity, in gallons, of the other smaller tank is C(x) = x +

Consider the region bounded by y = ex, y = 4, and x = 0 . A solid is created so that the given region is its base and cross-sections perpendicular to the y-axis are squares. Set up a Riemann sum and then a definite integral needed to find the volume of the solid. What is the approximate volume of a slice perpendicular to the y-axis? You can type the word Delta or use the CalcPad when you need Δ. (ln(y)2)Δy In your definite integral what is the lower endpoint? 0 In your definite integral what is the upper endpoint? 1 Evaluate the integral. Give an exact answer.

Yuto and Riko went for a bike ride on the same path. When Riko left their house, Yuto was 5.25 miles along the path. If Yuto’s average speed was 0.25 miles per minute and Riko’s average speed was 0.35 miles per minute, then Riko will be behind Yuto when 0 ≤ t < 52.5, where t is time in minutes. Explain what this solution means and why t cannot be less than zero.
