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.

Someone answer asap for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
