Midtown Independent School is making plans to move to a new building to meet the increasing number of students in its middle school. The school's enrollment over the last several years is shown on the scatter plot below. The line of best fit has been drawn for you. (1st pic) A) Choose the equation for the line of best fit.
a. y = 300x b. y = 2x + 300 c. y = 30x + 300 d. y = 2x + 5

B) The school must move to a new building once enrollment is more than 690 students. If the enrollment continues to increase at the current rate, what year must the new building be ready?

If sec theta = 5/3 and the terminal point determined by theta is in quadrant 4, then

In right ∆abc shown below, the midpoint of hypotenuse ac is located at d and segment bd is drawn.if ab = 12 and bc = 16, then explain why bd = 10. hint: consider what you know about the diagonals of a rectangle.

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?
