Explanation Given Information: The provided quadratic equation is 2 x 2 − x − 3 = 0 . Formula used: The value of x in the equation a x 2 + b x + c = 0 can be given by the quadratic formula, x = − b ± b 2 − 4 a c 2 a where a , b and c are real numbers with a ≠ 0 . Calculation: Consider the quadratic equation 2 x 2 − x − 3 = 0 . Compare the above equation with the equation a x 2 + b x + c = 0 , a = 2 , b = − 1 and c = − 3 Put the values of a , b , c in the quadratic formula x = − b ± b 2 − 4 a c 2 a . x = − ( − 1 ) ± ( − 1 ) 2 − 4 ⋅ 2 ( − 3 ) 2 ⋅ 2 = 1 ± 1 + 24 4 = 1 ± 25 4 = 1 ± 5 4 Further simplify, x = 1 + 5 4 = 6 4 = 3 2 Or x = 1 − 5 4 = − 4 4 = − 1 Check: For x = 3 2 Substitute the value of x = 3 2 in 2 x 2 − x − 3 = 0

Consider the region below f(x) = (11-x), above the x-axis, and between x = 0 and x = 11. Let x; be the midpoint of the ith subinterval. Complete parts a. and b. below. a. Approximate the area of the region using eleven rectangles. Use the midpoints of each subinterval for the heights of the rectangles. The area is approximately square units. (Type an integer or decimal.)

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
