Your computer is running extremely slow. Which of the following is the most likely cause? \( \begin{array}{ll}\text { A) Too many background applications running } \\ \text { B) A new wallpaper } \\ \text { - } & \text { C) High battery percentage } \\ \text { D) Latest software updates }\end{array} \)

\( 1000\int _{}^{}\frac{x^{3}}{\sqrt {x^{2}+100}} d x \)

Let \( d \) represent distance, \( r \) rate, and \( t \) time. Write the equation. \( d=\square \)

Choose the two equivalent expressions.

The polynomial function \( f \) is defined by \( f(x)=-3 x^{4}-7 x^{3}+3 x^{2}+9 x-1 \). Use the ALEKS graphing calculator to find all the points \( (x, f(x)) \) where there is a local minimum. Round to the nearest hundredth. If there is more than one point, enter them using the "and" button. \( (x, f(x))=\left(\prod_{1}, \square\right) \)
