Activity The equation of a circle centered at the origin with a radius of unit length is x2 + y2 = 1. This equation changes if the center of the circle is not

located at the origin or the radius is not of unit length. You will use the GeoGebra geometry tool to examine how the equation of a circle changes

as you move the center and change the radius. Go to equation of a circle C, and complete each step below. If you need help, follow these

instructions for using GeoGebra.

Question 1

Move the sliders to set the values of r, h, and k, and record at least three different sets of data. Also record the equations of the corresponding

circles.

How many grams the dog will eat in 3 days?

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?

Solve the triangle. a = 21°, c = 105°, c = 5
