Chapter 3, Problem 47RE

Rama/Shutterstock.com Romaset/Shutterstock.com The power station has three different hydroelectric turbines, each with a known (and unique) power function that gives the amount of electric power generated as a function of the water flow arriving at the turbine. The incoming water can be apportioned in different volumes to each turbine, so the goal of this project is to determine how to distribute water among the turbines to give the maximum total energy production for any rate of flow. Using experimental evidence and Bernoulli's equation, the following quadratic models were determined for the power output of each turbine, along with the allowable flows of operation: 6 KW₁ = (-18.89 +0.1277Q1-4.08.10 Q) (170 - 1.6 · 10¯*Q) KW2 = (-24.51 +0.1358Q2-4.69-10 Q¹²) (170 — 1.6 · 10¯*Q) KW3 = (-27.02 +0.1380Q3 -3.84-10-5Q) (170 - 1.6-10-ºQ) where 250 Q1 <1110, 250 Q2 <1110, 250 <3 < 1225 Qi = flow through turbine i in cubic feet per second KW = power generated by turbine i in kilowatts

uestion 10 of 12 A Your answer is incorrect. L 0/1 E This problem concerns hybrid cars such as the Toyota Prius that are powered by a gas-engine, electric-motor combination, but can also function in Electric-Vehicle (EV) only mode. The figure below shows the velocity, v, of a 2010 Prius Plug-in Hybrid Prototype operating in normal hybrid mode and EV-only mode, respectively, while accelerating from a stoplight. 1 80 (mph) Normal hybrid- 40 EV-only t (sec) 5 15 25 Assume two identical cars, one running in normal hybrid mode and one running in EV-only mode, accelerate together in a straight path from a stoplight. Approximately how far apart are the cars after 15 seconds? Round your answer to the nearest integer. The cars are 1 feet apart after 15 seconds. Q Search M 34 mlp CH

Find the volume of the region under the surface z = xy² and above the area bounded by x = y² and x-2y= 8. Round your answer to four decimal places.

У Suppose that f(x, y) = · at which {(x, y) | 0≤ x ≤ 2,-x≤ y ≤√x}. 1+x D Q Then the double integral of f(x, y) over D is || | f(x, y)dxdy = | Round your answer to four decimal places.

D The region D above can be describe in two ways. 1. If we visualize the region having "top" and "bottom" boundaries, express each as functions of and provide the interval of x-values that covers the entire region. "top" boundary 92(x) = | "bottom" boundary 91(x) = interval of values that covers the region = 2. If we visualize the region having "right" and "left" boundaries, express each as functions of y and provide the interval of y-values that covers the entire region. "right" boundary f2(y) = | "left" boundary fi(y) =| interval of y values that covers the region =

Find the volume of the region under the surface z = corners (0,0,0), (2,0,0) and (0,5, 0). Round your answer to one decimal place. 5x5 and above the triangle in the xy-plane with
