An engineer is designing a bridge to be built over a river to create a path for hikers to cross the water stream. The bridge will measure a distance of 350 meters and a height of 30 meters. Help the engineer calculate the stretch factor so that the bridge is built accurately, then write the complete vertex form equation needed to build the bridge.

The graph below shows the height of a projectile t seconds after it is launched. if acceleration due to gravity is -16 ft/s2, which equation models the height of the projectile correctly?

City l has a temperature of −3 °f. city m has a temperature of −7 °f. use the number line shown to answer the questions: number line from negative 8 to positive 8 in increments of 1 is shown. part a: write an inequality to compare the temperatures of the two cities. (3 points) part b: explain what the inequality means in relation to the positions of these numbers on the number line. (4 points) part c: use the number line to explain which city is warmer. (3 points)
