The school is 2.3 miles away from the library and 1.9 miles away from the post office. The expression (2.3m -1.9m) shows how many miles the library is closer to the school than it is to the post office. Which expression also shows how many miles the library is closer to the school than to the post office?

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much

Ab and bc form a right angle at point b. if a= (-3,-1) and b= (4,4) what is the equation of bc?

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?
