Noah and Lin are each trying to solve the equation 2² - 6x + 10 = 0. They know that the solutions to z? = -1 are i and –i, but they are not sure how to use this information to solve for z in their equation.
Lin decides to solve the equation using the quadratic formula. Here is her work:
X
-btvb2-4ac
2a
-(-6)/(-6)2-4(1)(10)
X
2(1)
61V36-40
Lin knows 36 – 40 is a negative number and isn't sure what to do next. Show how Lin can write her solution
using i.

In new york city at the spring equinox there are 12 hours 8 minutes of daylight. the longest and shortest days of the year very by two hours and 53 minutes from the equinox in this year the equinox falls on march 21 in this task you use trigonometric function to model the hours of daylight hours on certain days of the year in new york city a.what is the independent and dependent variables? b.find the amplitude and the period of the function. c.create a trigonometric function that describes the hours of sunlight for each day of the year. d. graph the function you build in part c. e. use the function you build in part c to find out how many fewer daylight hours february 10 will have than march 21. you may look at the calendar.
