An object is thrown straight upward. The velocity of the object 2 second after being thrown is 116 feet per second. The velocity of the object 4 seconds after being thrown is 52 feet per second. Which equation models the velocity of the object v , in feet per second, at a time t seconds after being thrown? Assume that the velocity changes at a constant rate. Multiple choice question.

A)
v=64t−12

B)
v=−64t+168

C)
v=32t+52

D)
v=−32t+180

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827

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?

The function f(x)= -(x+5)(x+1) is down. what is the range of the function?
