8x4x6 / 3 = 64

The general volume of a pyramid formula is given as: Volume of a pyramid = 1/3 x base area x height. Where Ab = area of the polygonal base and h = height of the pyramid.
LxWxH/3

The rule r y-axis R 0,90^ (x,y) is applied to triangle ABC . Which triangle shows the final image?

NemiM [27]

Answer:

Step-by-step explanation:

Given triangle ABC with vertices at points A(2,-4), B(4,-4) and C(4,-2).

1. Rotate this triangle anticlockwise by 90° angle over the origin. This rotation has the rule

$(x,y)\rightarrow (-y,x),$

then

$A(2,-4)\rightarrow A'(4,2)\\ \\B(4,-4)\rightarrow B'(4,4)\\ \\C(4,-2)\rightarrow C'(2,4)$

2. Reflect triangle A'B'C' across the y-axis. This reflection has the rule

$(x,y)\rightarrow (-x,y),$

then

$A'(4,2)\rightarrow A''(-4,2)\\ \\B'(4,4)\rightarrow B''(-4,4)\\ \\C'(2,4)\rightarrow C''(-2,4)$

These are vertices of triangle 1

Solve the given equation. (Enter your answers as a comma-separated list. Let k be any integer. Round terms to two decimal places

Ghella [55]

Answer:

That is the solutions are:

$\frac{\pi}{3}+2\pi \cdot k$ , $\frac{5\pi}{3}+2\pi \cdot k$

Step-by-step explanation:

The period of $\cos(x)$ or $\sin(x)$ is $2\pi$ .

Let's look at the first rotation to see when $\cos(\theta)=\frac{1}{2}$ happens.

This happens at $\frac{\pi}{3}$ and also at $\frac{5\pi}{3}$ . (Notice I just looked at the x-coordinates because that is what cosine is. Sine is the y-coordinate.)

Now to find the rest of the solutions we can just make full rotations either way to get back to those points .

That is the solutions are:

$\frac{\pi}{3}+2\pi \cdot k$

$\frac{5\pi}{3}+2\pi \cdot k$
