Lanu hit a volleyball into the air with an initial upward velocity of 24 feet per second. The height h in feet of the ball above the ground can be modeled by h = –16 + 24t + 3, where t is the time in seconds after Lanu hit the volleyball. Find the time it takes the ball to reach 12 feet above the ground.

Adaylily farm sells a portion of their daylilies and allows a portion to grow and divide. the recursive formula an=1.5(an-1)-100 represents the number of daylilies, a, after n years. after the fifth year, the farmers estimate they have 2225 daylilies. how many daylilies were on the farm after the first year?

Using the rise/run counting method, the slope of the line is

If the alternate hypothesis of an experiment is “the true mean height of the giraffes is more than 15 feet” what is the null hypothesis?
