Surface Area = 2 × Base Area + Lateral Area

What is the formula for the volume of a prism?

Volume = width x length × height

What is the formula for the volume of a pyramid?

$$volume\ of\ a\ pyramid=\ \frac{1}{3}Bh$$ Volume = (1/3) × Base Area × height

$$\left(\frac{x_{1\ }+\ x_2}{2}\ \right),\left(\frac{y_1\ +\ y_2}{2}\ \right)$$

What is the formula for Mean?

$$mean\ =\ \frac{Sum\ of\ Values}{#\ of\ values}$$ $$Mean\ =\ \frac{sum\ of\ values}{#\ ofvalues}$$ Mean = (Sum of all values) / (Number of values)

The sin of an angle equals what side over what side? $$\sin\ A\ =\ \frac{?}{?}$$

sin A = $$\frac{opposite}{hypotenuse}$$

The cosine of an angle equals what side over what side? $$\cos\ A\ =\ \frac{?}{?}$$

cos A = $$\frac{adjacent}{hypotenuse}$$

The tangent of an angle equals what side over what side? $$\tan\ A\ =\ \frac{?}{?}$$

tan A = $$\frac{opposite}{adjacent}$$

$$\frac{p}{r}\ because\ it\ is\ \frac{adjacent}{hypotenuse}$$

$$\frac{q}{r}\ because\ it\ is\ \frac{opposite}{hypotenuse}$$

$$\frac{q}{p}\ because\ it\ is\ \frac{opposite}{adjacent}$$

What is the slope of the line containing the following points. (1, 2), (6, 7)

$$slope\ =\ \frac{y_2-y_1}{x_{2\ }-\ x_1}$$ $$=\frac{7-2}{6\ -1}$$ $$=\ \frac{5}{5}=\ 1$$

What is the midpoint of the two points (5,3) and (-3, 5)

$$midpoint\ =\ \left(\frac{x_1+\ x_2}{2},\ \frac{y_1+\ y_2}{2}\right)$$ $$\left(\frac{5\ +\ -3}{2},\frac{3\ +\ 5}{2}\right)$$ $$\left(1,4\right)$$
