\bf i^3\implies \sqrt{-1}\cdot \sqrt{-1}\cdot \sqrt{-1}\implies (\sqrt{-1})^2\sqrt{-1}\implies \sqrt{(-1)^2}\cdot \sqrt{-1} \\\\\\ -1\cdot i\implies \boxed{-i}

Find the general solution for cos x = 0, where n is an integer.
Romashka-Z-Leto [24]
First we solve this equation:
x = cos^-1(0) = pi/2 and 3pi/2

Now, this is the answer for angles between 0 and 2pi

but there are "negative angles" and angles larger than 2pi
so the general solution that includes all of these cases is:

x = pi/2 + n*pi

here n is any integer.

Your television has a height of 20 inches and a length of 21 inches. What is the length of the diagonal?
Liula [17]

Answer:

29

Step-by-step explanation:

You take the two sides and make them to the second power so 20 would be 400 and 21 would be 441. You add those numbers to get 841. Than the square root of 841 is the answer which is 29

Write an equation in slope-intercept form for the line that passes through the given point and is perpendicular to the following
Valentin [98]
The perpendicular equation would include a slope that is the opposite reciprocal of the original slope.

Steps:
1. Get x to the other side in the original equation. This making the slope -4 or -4/1.

2. Turn the slope into it’s opposite reciprocal m = 1/4.

3. If you use point-slope form, y - y1 = m( x - x1 ), you can substitute y1 and x1 with the numbers in the point given. But since we previously found the opposite reciprocal, we will replace “m” as well. *By the way, the subtraction of a negative makes a positive. [y + 3 = 1/4( x + 4 )]

4. Solve:
A: Distribute (y + 3 = 1/4x + 1)
B: Subtract 3 from both sides (y = 1/4x -2)

Perpendicular Equation: y = 1/4x - 2
