Gerald purchased a rectangular plot of land. The length of the plot is 20 feet more than the width.
The cost of the land was $12 per square foot. Gerald
also had a fence put around the entire
perimeter of the plot, at a cost of $8 per linear foot.
The total amount he spent on both the land
and the fence was $10,560.
Part A
Write an equation in two variables for the perimeter, P.
and an equation in two variables for the area, A, of the
plot of land where x is the width of the plot in
Provide evidence to support your equations. o

1. a parachutist is 800 feet above the ground when she opens her parachute. she then falls at a constant rate of 5 feet per second. select the equation that represents this situation. h = -800t + 5 y = -5x + 800 h = 5t - 800 y = 800x + 5 i need

Three times the sum of a number and seven is negative thirty-six. what is the number?

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?
