What is the formula to calculate the total cost of renting a car based on daily rate and mileage?

Back

Total Cost = (Daily Rate * Number of Days) + (Cost per Mile * Number of Miles)

Front

Calculate the total cost of renting a car for 6 days at $35 per day and driving 350 miles at 42.5¢ per mile.

Back

Total Cost = (35 * 6) + (0.425 * 350) = $358.75

Front

What is the formula for evaluating a quadratic expression like 4x^2 - 11x?

Back

Substitute the value of x into the expression and simplify.

Front

Evaluate 4x^2 - 11x for x = -5.

Back

4(-5)^2 - 11(-5) = 155

Front

What is the cost formula for transferring mileage points?

Back

Cost = Processing Fee + (Cost per 100 Points * (Total Points / 100))

Front

Calculate the cost to transfer 7,000 mileage points with a $20 processing fee and $0.75 per 100 points.

Back

Cost = 20 + (0.75 * (7000 / 100)) = $72.50

Front

How do you find the midpoint of a line segment with endpoints (x1, y1) and (x2, y2)?

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

Front

Find the midpoint of the line segment with endpoints (-6, 9) and (2, 5).

Back

Midpoint = ((-6 + 2)/2, (9 + 5)/2) = (-2, 7)

Front

What is the Pythagorean theorem used for?

Back

To find the length of the hypotenuse in a right triangle: a^2 + b^2 = c^2.

Front

Calculate the length of the hypotenuse of a right triangle with legs of lengths 30 and 40.
