Francine solves the system of equations using the linear combination method.

4x+3y=-13x-5y=4

Which steps would allow her to eliminate the x terms in the system of equations?

Multiply 4x+3y=-1 by - 4. Multiply 3x-5y=4 by 3. Add the resulting equations together.

Multiply 4x+3y=-1 by 5. Multiply 3x-5y=4 by 3. Add the resulting equations together.

Multiply 4x+3y=-1 by 3. Multiply 3x-5y=4 by - 4. Add the resulting equations together.

Multiply 4x+3y=-1 by 4. Multiply 3x-5y=4 by 3. Add the resulting equations together.

Consider a classroom for 57 students and one instructor, each generating heat at a rate of 100 W. Lighting is provided by 18 fluorescent lightbulbs, 40 W each, and the ballasts consume an additional 10 percent. Determine the rate of internal heat generation in this classroom when it is fully occupied. The rate of internal heat generation in this classroom when it is fully occupied is W.

Write a program that reads a string containing exactly four words (separated by * symbols) into a single string object. Next, extract each word from the original string and store each word in a string object. Then concatenate the words in reverse order to form another string. Display both the original and final strings. (Hint: To extract the words, you should use the find member function to find each symbol *, assign the characters up to the * to one of the four string objects, and then remove those characters from the original string.)

The Reynolds number is a dimensionless group defined for a fluid flowing in a pipe as Re Durho/μ whereD is pipe diameter, u is fluid velocity, rho is fluid density, and μ is fluid viscosity. When the value of the Reynolds number is less than about 2100, the flow is laminar-that is, the fluid flows in smooth streamlines. For Reynolds numbers above 2100, the flow is turbulent, characterized by a great deal of agitation. Liquid methyl ethyl ketone (MEK) flows through a pipe with an inner diameter of 2.067 inches at an average velocity of 0.48 ft/s. At the fluid temperature of 20°C the density of liquid MEK is 0.805 g/cm3 and the viscosity is 0.43 centipoise [1 cP 1:00 103 kg / m s]. Without using a calculator, determine whether the flow is laminar or turbulent. Show your calculations.
