<span>Hi! All you need to know is that cot stands for cotangent and its the reciprocal of tan i.e. cot(x) = 1/tan(x). You probably know that tan(pi/4) = 1 and that tan(3pi/4) = -1. Happily in these cases it means that cot and tan come out the same (1/1 = 1 and 1/-1 = -1).
-1 - (+1) = -2 and this divided by pi/2 = -2/(pi/2) which looks a bit untidy so multiply the top and bottom by 2 (to get rid of the 2 in pi/2) and the answer is -4/pi. HTH</span>
They disagreed with the ratification because they believed that it would give the executive branch too much power. As a result, Madison wrote the Bill of Rights
Answer:
A
Step-by-step explanation:
Because x has the degree one and it’s figure at the numerator
In order to find a square feet, you must evaluate the area of a specific shape. Then, you must apply the shape’s formula for area.
Examples:
Rectangle: lw or Length x Width
Circle: pi x r^2 or 3.14159... x radius squared
Triangle: 1/2 bh 1/2 base x height
Answer: 9x + 4x²
Explanation:
1) Length = 14x - 3x² + 2y
2) Width = 5x - 7x² + 7y
3) Length - width = [14x - 3x² + 2y] - [5x - 7x² + 7y]
4) Calculate:
i) Distribute the negative sign in front of the second polynomial:
14x - 3x² + 2y - 5x + 7x² - 2y
ii) Combine like terms:
9x + 4x²
5) Answer: 9x + 4x²
