Kara and Lindsey both hike in separate directions from their campsite, with Kara hiking straight to the east and Lindsey hiking straight north. At 2:00 p. m., Kara hiked twice as far to the east as Lindsey hiked to the north. At 2:30 p. m., Kara had covered another mile, while Lindsey had covered another half of a mile. If x represents Lindsey's distance, in miles, from the campsite at 2:00 p. m., what function could be used to represent the area of the triangular region formed by the girls' locations and the campsite at 2:30 p. m.?

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.

step-by-step explanation:

the radius is 2 times the diameter.
