Will give 20 points! 2. the children’s hospital sponsors a 10 k rac e to raise money. it receives $7 5 per race entry and $10,000 in donations , but it must spend $2 5 per race entry to cover the cost of the race. write and solve an inequality to determine the number of race entries the ch arity needs to raise at least $100 ,000

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?

The graph of h(x)= |x-10| +6 is shown. on which interval is this graph increasing

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d. what is the height of the tide after 93 hours?
