Follow the directions to convert the analog sound wave into a digital signal. The lines on the grid intersect at various points

(x, y). For each whole-number value of x, find the intersection point that is closest to the wave. Draw a small circle on that point, and record its y-value. The circles for the x-values 0 through 3 are already done for you. Draw circles for the x-values 4 through 18. In a textbox, write down all 19 y-values obtained by sampling the wave.

Use the cross product to find the sin(θ) where θ is the angle between v and w where v=i+j and w=i+j+k.
romanna [79]
\|\mathbf v\times\mathbf w\|=\|\mathbf v\|\|\mathbf w\|\sin\theta

\mathbf v\times\mathbf w=\begin{vmatrix}\mathbf i&\mathbf j&\mathbf k\\1&1&0\\1&1&1\end{vmatrix}
\mathbf v\times\mathbf w=\begin{vmatrix}1&0\\1&1\end{vmatrix}\mathbf i-\begin{vmatrix}1&0\\1&1\end{vmatrix}\mathbf j+\begin{vmatrix}1&1\\1&1\end{vmatrix}\mathbf k

\mathbf v\times\mathbf w=\mathbf i-\mathbf j
\implies\|\mathbf v\times\mathbf w\|=\sqrt{1^2+(-1)^2}=\sqrt2

\mathbf v=\sqrt{1^2+1^2}=\sqrt2
\mathbf w=\sqrt{1^2+1^2+1^2}=\sqrt3

\sqrt 2=\sqrt2\cdot\sqrt3\sin\theta
\dfrac1{\sqrt3}=\sin\theta

Question 67 and 68 please. Or one or the other.
Umnica [9.8K]

Answer:

question 67-the answer is Rory has eaten 1 1/4 of all the chocolate he has been given.

question 68-answer A-30 degrees

Step-by-step explanation:

question 67:

first Rory ate 1/2 of his chocolate

then, his sister gave him another whole chocolate bar an hour later.

that is 1/2+1=1 1/2--3/2/2=3/4

add 3/4 and 1/2--3/4 1/2~2/4--2/4+3/4=5/4 or 1 1/4

so the answer is 1 1/4

question 68:

if you draw a base to connect the last side of the angle into a triangle, you find that all three sides are equal, making the triangle an equilateral triangle.  An equilateral triangle's angles all equal 30 degrees.

so, the answer is answer A: 30 degrees

Which is equivalent to |20|?
Annette [7]

Hey there!

Usually when people are trying to find absolute value we are trying to REMOVE your NEGATIVE in FRONT of your given number and make them almost positive (e.g. 0)

|20| = (positive) 20 because it’s the absolute value of itself ; if your equation was |-20| you would have to say your absolute value would be 20

Answer: |20| = 20 ☑️

Good luck on your assignment and enjoy your day!
