Clark has been given seven tasks to do al work, but she has tume to complete only four them. She mus decide in what order to do the ack. How many possible onderings of foum tasks are avalable to Soraya?

Fill in the missing values to make the equations true. (a) \( \log _{5} 3+\log _{5} 4=\log _{5} \square \) (b) \( \log _{8} 11-\log _{8} \square=\log _{8} \frac{11}{5} \) (c) \( 2 \log _{8} 5=\log _{8} \square \)

Determine whether the following equation defines \( y \) as a function of \( x \). \( x^{2}+y^{2}=16 \) Does the equation \( x^{2}+y^{2}=16 \) define \( y \) as a function of \( x \) ? Nos

\( \left. \begin{array} { l }{ - ( \frac { 2 } { 5 } ) ^ { 2 } = \square } \\ { \frac { 4 ^ { 3 } } { 5 } = \square } \end{array} \right. \)

Evaluate. \[ \frac{(-4-3)^{2}-10}{3-4^{2}} \]

If \( x \) and \( y \) are the dimensions of a rectangle whose area is 8 and whose perimeter is as small as possible, then \( x^{2}+y^{2}= \) a. 32 b. 12 c. 20 d. 24 e. 16
