Q 9. Perform the calculation. \[ (9-3)!=\square \]

rough the points \( (-9,-5) \) and \( (-1,-9) \) ? Write

Use the price-demand equation below to find \( E(p) \), the elasticity of demand. \( x=f(p)=3300-3 p^{2} \)

Noa drove from the Dead Sea up to Jerusalem. When she arrived in Jerusalem after 1.5 hours of driving, her altitude was 710 meters above sea level. Heraltitude increased at a constant rate of 740 meters per hour. Let \( y \) represent: Noa's altitude (in meters) relative to sea level after \( x \) hours. Complete the equation for the relationship between the altitude and number of hours.

1) \( \begin{array}{l}\left.\left[6^{5} \cdot 7^{4} \cdot\left(6^{5} \cdot 7\right) \cdot 6\right] \cdot(6 \cdot 7)\right] \cdot[(7)] \\ {\left[7^{5} \cdot\left(6^{2} \cdot 7^{4} \cdot 6^{5} \cdot 7\right)^{3}\right]^{6}}\end{array} \)
