Question 1 Neptune's diameter is a little less than \( 5 \times 10^{7} \) meters. How is this number expressed in standard notation?

LUESTION 9 The derivative of \( y=4 x^{2}-x+1 \) is \( \begin{array}{ll}\text { A. } 8 x & \text { B. } 7 x \\ \text { C. } 2 x-1, & \text { D. } 8 x-1\end{array} \)

Perform the following arithmetic operations on the given complex numbers. a. Add. \( (1+5 i)+(-1+2 i) \) b. Subtract. \( (1+5 i)-(-1+2 i) \) c. Multiply. \( (1+5 i)(-1+2 i) \) d. Divide. \( \frac{1+5 i}{-1+2 i} \) e. Evaluate. \( i^{71} \). ( \( 1+5 \).

Write the expression as a sum and/or difference of logarithms. Express powers as factors. \( \ln \left(x^{4} \sqrt{2-x}\right), 0
