What is the formula to find the slope of a line?

• Slope (m) = (y2 - y1) / (x2 - x1)

• Slope (m) = (x2 - x1) / (y2 - y1)

• Slope (m) = y2 + y1 / x2 + x1

• Slope (m) = (y1 - y2) / (x1 - x2)

What is the significance of scientific notation in mathematics?

• It allows for easier representation and calculation of very large or very small numbers.

• It is used exclusively for statistical analysis.

• It simplifies the process of addition and subtraction only.

• It is a method for converting fractions into decimals.

What is the first step in determining if a set of numbers is a Pythagorean Triple?

• Check if the square of the largest number equals the sum of the squares of the other two numbers.

• Verify if the numbers are all even or all odd.

• Calculate the average of the three numbers.

• Determine if the largest number is greater than the sum of the other two.

How do you find the height of a cylinder if you know its volume and radius?

• Height = Volume / (πr²)

• Height = Volume * (πr²)

• Height = (πr²) / Volume

• Height = Volume + (πr²)

• 4021.5 ft³

• 1809.6 ft³

What is a Pythagorean Triple?

• A set of three positive integers a, b, and c that satisfy the equation a² + b² = c².

• A group of three angles that sum up to 180 degrees.

• A collection of three sides of a triangle that are all equal in length.

• A sequence of three numbers that are in arithmetic progression.

What is the formula for the area of a circle?

• Area = 2πr

• Area = πr²

• Area = πd

• Area = r²

How do you calculate the volume of a cylinder?

• Volume = 2πrh

• Volume = πr²h

• Volume = πr² + h

• Volume = 4/3πr³
