OPENING PROBLEM A square garden gazebo is surrounded by 4 semi-circles of
lawn as shown.
For a wedding, quarter circles of flowers are planted in
each corner of the gazebo. The lawn covers 4 times as
much area as the flower beds.
Suppose the flower beds are metres apart as shown.
2 m
Things to think about:
10 m
a Explain why the radius of each flower bed is 5
b Hence, show that 22 – 20x + 50 = 0.
c By solving this equation, can you find the distance between the flower beds?

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?

Ireally need subtract and simplify.(-y^2 – 4y - 8) – (-4y^2 – 6y + 3)show your work, ! i will mark you brainliest but you have to show your work.
