An arrow is shot vertically upward from a platform 45 feet high at a rate of 168 ft/sec. Use the quadratic equation ℎ=−162+168+45 to find how long it will take the arrow to reach its maximum height, and then find the maximum height.

Write the sentence as an equation. z plus 372 is equal to 160

1. there are 25 students who started computer programming in elementary school and 25 students who started computer programming in middle school. the first group had a mean final project grade of 95% and the second group had a mean final project grade of 92%. the line plot shows the differences after 10 rerandomizations. determine whether the difference in the means of the two groups is significant based on the line plot. explain your answer.

25 ! the line of best fit is h = 5a + 86. predict the height at age 16. show your work.
