In the year 1900, the total number of metric tons of copper produced in the world was
495,000. Each year since 1900, the total number of metric tons of copper produced has
increased on average by about 3.25% over the amount produced the previous year.
Which function models the total number of metric tons of copper produced in the year that is
x years since 1900?
A
c(x) = 495,000(1.0325)*
B c(x) = 495,000(0.9675)*
C
c(x) = 495,000x1.0325
D (x) = 495,000x0.9675

What is the most accurate measurement of 1 pound

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?
