Jill has 120 feet of fencing to use for her horse paddock. To increase the area she can enclose, she plans on using the side of
the barn as one side of her paddock as shown below. Determine which equation can be used to find the dimensions of the horse paddock when the area is 1,800 square feet. Let x represent the width of the paddock.
Answer: <span>-x2 + 120x = 1,800 </span><span> She plans on using the side of the barn as one side of her paddock so it has 3 sides. Since the width is shorter, it will be more efficient to have 2 widths (1 lengths and 2 widths). Because J</span><span>ill has 120 feet of fencing to use, you can get this equation: 120ft= 1L +2W </span>1L= 120-2W
If you insert it into area formula it would be: area= L*W area= (120-2W) *W area= 120W- 2W^2 -2W^2+120W= area
<span>Since x represent the width of the paddock and the area is 1800 the equation become </span>-2X^2+120X= 1,800
vertex (1,-1) axis of symmetry is x=1, domain all real numbers (i think neg ys) range y is less equal than -1, y increases as x less 0 bug IMO x decreases
