A farmer has a large field that is x feet in length. He wants to fence in a rectangular section in the middle of the field, leaving
a length of 100 feet of open field beyond each end of the fenced rectangle. He also wants the width of the fenced-in space to
be 100 feet less than its length, as shown in the diagram.
Find the equation in standard form for the area of the fenced-in section in terms of the length of the field.
(area = length. width)
(x - 300) ft
100 ft
100 ft
(x - 200) ft
x feet
Type the correct answer in the box.

Find the domain of the following expression: 1/(√x)-2

For the inequality |c| < |d| to be true, which of the following must be true?

Determine if the following statement is true or false. the normal curve is symmetric about its​ mean, mu. choose the best answer below. a. the statement is false. the normal curve is not symmetric about its​ mean, because the mean is the balancing point of the graph of the distribution. the median is the point where​ 50% of the area under the distribution is to the left and​ 50% to the right.​ therefore, the normal curve could only be symmetric about its​ median, not about its mean. b. the statement is true. the normal curve is a symmetric distribution with one​ peak, which means the​ mean, median, and mode are all equal.​ therefore, the normal curve is symmetric about the​ mean, mu. c. the statement is false. the mean is the balancing point for the graph of a​ distribution, and​ therefore, it is impossible for any distribution to be symmetric about the mean. d. the statement is true. the mean is the balancing point for the graph of a​ distribution, and​ therefore, all distributions are symmetric about the mean.
