Learn how to solve a word problem involving roots

The video tutorial explains how to solve a word problem involving a clothing manufacturer and defective blouses. It defines variables D and N, representing defective blouses and total blouses produced, respectively. The function D = 0.123455N² is introduced, and the process of solving for N when D is given is demonstrated. The tutorial also explores the impact of increasing the number of defective blouses by a factor of nine, showing how it affects the total number of blouses produced.

What does the variable D represent in the context of the clothing factory problem?

• Number of blouses sold

• Total number of employees

• Number of defective blouses

• Total number of blouses produced

How do you solve for the total number of blouses produced when given the number of defective blouses?

• Add the number of defective blouses to the total number of blouses

• Subtract the number of defective blouses from the total number of blouses

• Multiply the number of defective blouses by the total number of blouses

• Divide the number of defective blouses by the constant and take the square root

Why is only the positive value of N considered in the solution?

• Because the problem specifies positive values only

• Because the function only allows positive values

• Because negative values do not make sense in the context of production

• Because negative values are not allowed in mathematics

If the number of defective blouses is increased by a factor of nine, how does the total number of blouses produced change?

• It doubles

• It remains the same

• It increases by a factor of three

• It decreases by a factor of nine

What mathematical concept is related to the change in the total number of blouses when the defective blouses are increased by a factor?

• Division

• Subtraction

• Addition

• Geometry and squaring
