NASA launches a test rocket with an initial velocity of 211 meters per second from an initial height of 22 meters above sea-level. Find a quadratic function that models the height of the rocket, in meters above sea-level, as a function of time t
, in seconds after the launch. (HINT: 4.9 meters = 16 feet) Use your model to answer the following questions.

Solve 5 tan x = 5√(3) for 0° ≤ x ≤ 180°. a. 60° b. 150° c. 30° d. 120°

Lin is writing an equation to model the proportional relationship between y, the total cost in dollars of downloading videos from a website, and x, the number of videos downloaded. she knows that the total cost to download 3 videos was $12. her work to find the equation is shown below. joylin’s work step 1 k= 3/12= 0.25 step 2 y= 0.25x where did joylin make her first error?
