You put a force sensor on the rope, and finally you pull hard enough that the box starts sliding. You pulled with 500 N of force before the box started moving. What is the coefficient of static friction (Enter your answer to 2 decimal places)

a. \( \frac{2}{8}= \)

- \( x \)-intercept of \( \frac{1}{4} \) - \( y \)-intercept of \( -\frac{1}{2} \)

Considere la función dada por: \[ f(x)=\left\{\begin{array}{ll}\frac{x^{2}-2 x-3}{1-x^{2}} & \text { si } x<-1 \\ a x+b & \text { si }-1 \leq x \leq 1 \\ \frac{\sqrt{x^{2}+3 x}-x}{x} & \text { si } x>1\end{array}\right. \] Halle los valores de \( a \) y \( b \) para que \( f(x) \) sea continua en todo número real.

How does the process of archaeological discovery differ from simply digging with \[ \text { shovels? } \] Archaeologists only study artifacts in museums. Archaeologists meticulously reveal remnants in a methodical process. Archaeologists use shovels to quickly uncover artifacts.
