What is the height of a prism?

• The distance between the bases

• The length of the base

• The area of the base

• The volume of the prism

What is the formula for the area of a rectangle?

• Area = length + width.

• Area = length × width.

• Area = length - width.

• Area = length / width.

How do we solve equations?

• 1. Type left side into Desmos 2. Type right side into Desmos 3. See where the two lines cross

• 1. Add both sides of the equation together 2. Divide by the same number 3. Check the result

• 1. Multiply both sides by zero 2. Simplify the equation 3. Find the roots

• 1. Graph the equation on paper 2. Estimate the intersection point 3. Verify with a calculator

• The slope of the line

• The intercept of the line

• The distance formula

• The quadratic formula

What is the x-intercept?

• The point where a graph crosses the x-axis.

• The point where a graph crosses the y-axis.

• The maximum point of a graph.

• The minimum point of a graph.

What is a scatter plot?

• A type of chart that displays data in a circular format.

• A graph that shows the relationship between two variables using dots.

• A diagram that represents data in a hierarchical structure.

• A table that organizes data into rows and columns.

What is the formula for the volume of a cylinder?

• Volume = @@rac{1}{3} imes ext{Base Area} imes ext{Height}@@

• Volume = @@rac{4}{3} imes ext{Base Area} imes ext{Height}@@

• Volume = @@ ext{Base Area} imes ext{Height}@@

• Volume = @@ ext{π} r^2 h@@

What is the Pythagorean theorem?

• In a right triangle, @@a^2 + b^2 = c^2@@, where c is the hypotenuse.

• The sum of the angles in a triangle is 180 degrees.

• In any triangle, the longest side is always opposite the largest angle.

• The area of a triangle is given by the formula @@rac{1}{2} imes base imes height@@.

What are the 3 types of relations in scatter plots?

• Positive, Negative, No Correlation

• Linear, Exponential, Logarithmic

• Direct, Indirect, Neutral

• Strong, Weak, Moderate
