Answer:
One fourth is the same as dividing one whole into four equal fourths. Similarly, dividing 12 by 4 is the same as dividing one whole 12 into fourths.
For the largest area, half the fence is used parallel to the river, and the other half is used for the two ends of the rectangular space.
The dimensions are 475 m by 237.5 m.
_____
Let x represent the length along the river. Then the area (A) is found as
.. A = x*(950 -x)/2
This equation describes a parabola with its vertex (maximum) halfway between the zeros of x=0 and x=950. That is, the maximum area is achieved when half the fence is used parallel to the river.
To find the range of these scores, we must take the largest scores and subtract the smallest from it.
The largest score is 99, and the smallest score is 80.
99 - 80 = 19
Athe answer is -2 because it is behind the 0 and will be negative and it is two lines away from the 0 so the answer is -2
