Direct and Inverse Variation Quiz

What is the main focus of the video tutorial?

• Learning about calculus

• Understanding direct and inverse variation

• Solving algebraic equations

• Studying geometry

In the direct variation problem, what does the distance required to stop a car depend on?

• The car's color

• The car's weight

• The car's fuel type

• The car's speed

What is the formula for direct variation used in the video?

• D = K / S

• D = K * S

• D = K * S^2

• D = K / S^2

How is the constant of variation (K) calculated in the direct variation problem?

• By subtracting speed from distance

• By adding distance and speed

• By dividing distance by the square of speed

• By multiplying distance and speed

What is the stopping distance for a car traveling at 96 mph according to the problem solved?

• 720 feet

• 640 feet

• 800 feet

• 500 feet

In the inverse variation problem, what does the time to complete a project depend on?

• The project budget

• The number of employees

• The project deadline

• The project location

What is the formula for inverse variation used in the video?

• T = K * E

• T = K / E

• T = E / K

• T = K + E

How is the constant of variation (K) calculated in the inverse variation problem?

• By subtracting the number of employees from time

• By adding time and the number of employees

• By multiplying time and the number of employees

• By dividing time by the number of employees

How long will it take five people to complete the project according to the problem solved?

• 3.5 days

• 4.2 days

• 5.0 days

• 6.0 days

What is the relationship between time and the number of employees in the inverse variation problem?

• Time remains constant regardless of the number of employees

• Time decreases as the number of employees increases

• Time increases as the number of employees increases

• Time is unrelated to the number of employees
