Complete the conjecture that describes the pattern in the sequence. \( 4,8,12,16,20 \)

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

If \( f(x)=6^{7-x}+1 \), what is the value of \( f(2) \), to the nearest ten-thousandth (if necessary)?

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

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

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
