What is the slope of the line that passes through the points (-1, -4) and (3, 2)?

25. \( |5|-|-8|= \) 26. \( |-2|+|7|= \) 27. \( |12|-|-6|= \) 28. \( |-3|+9= \) 29. \( |10|-|6|= \) \( 14-|5|= \)

Perform the indicated operations. Write the result in scientific notation rounded to three significant digits. \[ \left(\frac{9.6 \times 10^{-3}}{\left(2.45 \times 10^{-4}\right)\left(1.1 \times 10^{5}\right)}\right)^{6} \]

3.(1 ponnt) Perform the indicated operations. Express the result using positive exponents. \[ 10^{-6} \cdot 10^{-1} \cdot 10^{4} \] a) \( 10^{24} \)

39. \( -4(6+4) \div(-2)+1= \) 40. \( 12 \div(7-4)-2= \) 41. \( 1+4^{2} \div(3+1)= \)

Simplify the complex number \( i^{66} \) as much as possible.
