No product results in -1, hence δlmn is NOT a right triangle showing that lydia's assertion is incorrect
<h3>Perpendicular lines</h3>
In order to determine whether triangle lmn is right-angled, we need to determine the slope of lm, ln, and mn first as shown:
For the slope of lm:

For the slope of ln:

For the slope of mn:

- If any of the two lines is perpendicular, hence the triangle lmn is right-angled.
- To check, we will take the product of the slopes and see if it is equivalent to -1.
Product of slope lm and ln

Since no product results in -1, hence δlmn is NOT a right triangle showing that Lydia's assertion is incorrect

The dimensions of the smaller holding pens from the parameters given are; 96 ft and 31 ft
<h3>What dimensions will maximize the area?</h3>
From the complete question, if the side lengths of the big rectangle are x and y, then the expression for the area A is:
A = x*y
Then perimeter since we have 384 ft of fencing available is;
2x + 2y = 384
y = (384 - 2x)/2
y = 192 - x
Put 192 - x for y in area formula;
A = x(192 - x)
A = 192x - x²
Completing the square of this are equation gives;
A = 9216 - (x - 96)²
This means that A is maximum at x - 96 = 0
Thus, A is maximum when x = 96 ft
At A_max; y = 192 - 96 = 96 ft
Since the area of the bigger rectangle has been maximized, it means that we have also maximized the area of the smaller pens. Therefore its' dimensions will be;
x_small = 96 ft/3 = 31 ft
y_small = 96 ft

The formula weight of
is equal to 136.02 g/mol.
The formula weight of a chemical compound is calculated by adding the atomic masses of each chemical element contained in the compound, while multiplying them by the number of atoms respectively.
From the periodic table, the atomic mass of each chemical element is:
Formula weight of
= ![12.0107 + [14.0067+ (15.999 \times3)]\times 2](https://tex.z-dn.net/?f=12.0107%20%2B%20%5B14.0067%2B%20%2815.999%20%5Ctimes3%29%5D%5Ctimes%202)
![F = 12.0107 + [14.0067+ 47.997] \times 2\\\\F = 12.0107 + 124.0074](https://tex.z-dn.net/?f=F%20%3D%2012.0107%20%2B%20%5B14.0067%2B%2047.997%5D%20%5Ctimes%202%5C%5C%5C%5CF%20%3D%20%2012.0107%20%2B%20124.0074)
F = 136.02 g/mol.

Answer: Forex trading is similar to buying and selling other types of securities, like stocks. When you make a forex trade, you sell one currency and buy another. You profit if the currency you buy moves up against the currency you sold. A currency trading platform is a software interface provided by currency brokers to their customers to give them access as traders in the forex markets. This may be an online, web-based portal, mobile app, a standalone downloadable program, or any combination of the three.
