To fill the blanks with the appropriate word for the statement: the operation name of interchanging two equations of system of linear equations.

Answer to Problem 4E
Interchanging two operations of a system of linear equations is a row operation that produces an equivalent system.
Explanation of Solution
Method of elimination can be applied for more than one variable. This elimination is also used in computer to solve the system of linear equations. The system of linear equation can be converted into row-echelon form for the use of elimination method. An example of row echelon conversion is shown below:
This row-echelon form can achieved by the number of row operation in the coefficeint matrix of system of linear equations. Also, interchanign of two equations of lineat equations is known as row operation which is used to get row-echelon form. This is process of row oprations is known as Gaussian elimination.

- 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.

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 kilowattsarrow_forwardHello!
