Evaluate the following expressions. Your answer must be an angle in radians and in the interval \( \left[-\frac{\pi}{2}, \frac{\pi}{2}\right] \) (a) \( \sin ^{-1}(1)=\square \) (b) \( \sin ^{-1}\left(-\frac{\sqrt{2}}{2}\right)=\square \) (c) \( \sin ^{-1}\left(-\frac{1}{2}\right)=\square \)

\( k(x)=10 x^{3}+8 \) \( k^{-1}(x)=\sqrt[3]{\frac{x}{10}}-\frac{4}{5} \quad \) I

pass up your opportunity to vote in the upcoming election?" Only \( 5 \% \) of the 250 people reached in the poll say they plan on staying home. Which of these is the best explanation for why this result is probably biased? Choose 1 answer: A Some people in the sample probably couldn't be reached, so this is (ikely an overestimate. (C) Peome people in the sample probably couldn't be reached, so this is rather than voting, so this is likely an overestimate. (D) People may not want to admit that they plan on staying home rather than voting, so this is likely an underestimate.

Use algebra to find the inverse of the function \( f(x)=6 x^{7}-6 \). The inverse function is \( f^{-1}(x)=\square \)

(4) Which of the following equations cannot be used to represent the area model? (A) \( 42 \times ?=4,326 \) (B) \( 42+4,326= \) ? (C) \( 4,326 \div ?=42 \) (D) \( 4,326 \div 42= \) ?
