2.A firecracker is launched vertically from the ground with an initial velocity of 48 ft/sec. (a)
Write a quadratic function h(t) that shows the height, in feet, of the firecracker t seconds after it was launched. Use the general equation h(t) = -16t2 + V + H where Iv is the initial velocity and H is the initial height. Also, what is the y axis, what does the y axis represent, and what is the axis of symmetry?

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)
