Step-by-step explanation:
I have another set of choices here:
A. {0.5, 1, 2}
B. {1, 2, 4}
C. {1, 2, 3, 4, 5}
<span>D. {0}
</span>
If you multiply two numbers from a closed set the answer is in the set.
<span>So A is not closed because 2 x 2 = 4 which isn't in the set. Only 0.5, 1, and 2 are in set A. </span>
<span>Try multiplying the largest numbers in sets B, C, and D by themselves. You will soon discover the closed set.</span>
If she chose the color she would have 12 options left.
20f? Perimeter is simply all sides added up together.
Answer:
Step-by-step explanation:
Given that a rectangle is constructed with its base on the x axis and two of its vertices on the parabola

This parabola has vertex at (0,100) and symmetrical about y axis.
Any general point above x axis can be written as (a,b) (-a,b) since symmetrical about yaxis.
Hence coordinates of any rectangle are

Length of rectangle = 2a and width = 
Area of rectangle = lw = 
To find max area, use derivative test.

Hence maxima when first derivative =0
i.e. when a =2
Thus we find dimensions of the rectangle are l =4 and w = 96
Maximum area =
