47.Explain sound needs a medium for propagation
Answer:
Sound needs a material medium for their propagation like solid, liquid or gas to travel because the molecules of solid, liquid and gases carry sound waves from one point to another. Sound cannot progress through the vacuum because the vacuum has no molecules which can vibrate and carry the sound waves.
Fred helped his mom make 40 dozen cupcakes for the last bake sale. For this sale, he is going to help make 20% more cupcakes. How many dozen cupcakes will Fred and his mom make?
Answer:
48 dozen cupcakes
Step-by-step explanation:
20 percent more is 120 percent overall, which as a decimal is 1.2. Multiply 40 by 1.2 and you have your answer.
1.2 * 40 = 48

Solve the equation. (Find all solutions of the equation in the interval [0, 2pi). Enter your answers as a comma-separated list.)
(3 sin(2x) + 3 cos(2x))^2=9
I got
[tex]0.75 + 2\pi \times n[/tex]
[tex]5.28 + 2\pi \times n[/tex]
[tex]1 + 2\pi \times n[/tex]
5.53+2pi times n
WORK:
[tex](3 \sin(2x) + 3 \cos(2x) )) {}^{2} = 9[/tex]
[tex] \sin(2x) + \cos(2x) {}^{2} = 3[/tex]
[tex] \sin(x) + \cos(4 {x}^{2} ) = 3[/tex]
[tex]4 {x}^{2} + x = 3[/tex]
[tex]4 {x}^{2} + x - 3 = 0[/tex]
[tex](4x {}^{2} + 4x - 3x - 3 = 0[/tex]
[tex]4x(x + 1) - 3(x + 1) = 0[/tex]
[tex](4x - 3)(x + 1)[/tex]
Solve for x
[tex]4x - 3 = 0[/tex]
[tex]4x = 3[/tex]
[tex]x = \frac{3}{4} [/tex]
[tex]x + 1 = 0[/tex]
[tex]x = - 1[/tex]
While -1 is a solution, it isn't within the interval of 0,2pi.
However, we can use the reference angle identity
[tex] \cos(x) = \cos(x + 2\pi) [/tex]
So some more possible points are
[tex] - 1 + 2\pi[/tex]
Since it on a interval, it must be less than 2 pi or 6.28.
Let find some more points
[tex] - 1 + 2\pi = 5.28[/tex]
So 5.28 is a point,
[tex] \frac{3}{4} + 2\pi = 7.03[/tex]
That is too big since -6.28 is smaller than 7.03
We can use the identity
[tex] \cos(x) = \cos( - x) [/tex]
[tex] \cos( - 1) = \cos( 1 ) [/tex]
1 is smaller than 2pi so it is true.
[tex] \cos( \frac{3}{4} ) = \cos( - \frac{3}{4} ) [/tex]
Negative 3/4 is smaller than zero so it not a solution.
[tex]0.75[/tex]
[tex]5.28[/tex]
[tex] 1[/tex]
Make sure to include
[tex]2\pi \times n[/tex]
so
[tex]0.75 + 2\pi \times n[/tex]
[tex]5.28 + 2\pi \times n[/tex]
[tex]1 + 2\pi \times n[/tex]
We can also -3/4 plus 2 pi.
Which is about 6

What is the value of 6(2b-4) when b=5?
Replace b with 5:
6(2(5)-4)
Simplify:
6(10-4)
Subtract:
6(6)
Multiply to get the answer: 36
The answer is 36
Hey there!
6(2b - 4)
= 6(2(5) - 4)
= 6(10) - 4)
= 6(10) + 6(4)
= 60 - 24
= 36
Therefore, your answer should be: 36

Median is the middle value.
Each set has 7 numbers so put the numbers in order from smallest to largest. The median would be the 4th number in the sets.
Only 2 sets have the number 15 in them so those are the only two you need to look at.

The value of the matrix X is X = [tex]\left[\begin{array}{ccc}-7&-2\\7&0\\\end{array}\right][/tex].
What are Matrices?Matrices are a set of numbers arranged in such a way that the numbers are arranged in rows and columns.
Each number is called element in a matrix.
Given are two matrices.
A = [tex]\left[\begin{array}{ccc}2&-7\\6&1\\\end{array}\right][/tex] and B = [tex]\left[\begin{array}{ccc}-9&5\\1&-1\\\end{array}\right][/tex]
We have given that, a matrix X exists such that,
X - A = B
We can rearrange this as,
X = A + B
Adding the two matrices,
The entries will be,
2 - 9 = -7
-7 + 5 = -2
6 + 1 = 7
1 - 1 = 0
X = [tex]\left[\begin{array}{ccc}-7&-2\\7&0\\\end{array}\right][/tex]
Hence the X is option A.

Step-by-step explanation:
Carter is solving for x by the process of completing the square for the following
problem:
3x^2+ 12x-24 = 0
He got to this point below:
Type the number that goes in the "?" spot:
(x+?)2 = 12
Answer:
The number that goes in place of the question mark is 2.
Step-by-step explanation:
Let's solve it!
3x² + 12x - 24 = 0
First we can factor 3 out of each term:
x² + 4x - 8 = 0
Now we'll add 12 to both sides to complete the square:
x² + 4x + 4 = 12
And finish it off:
(x + 2)² = 12
So the answer to the question is 2
Bonus:
We can also now solve this for x:
(x + 2)² = 12
x = √12 - 2
x = 2√3 - 2
x ≈ 2 × ±1.732 - 2
x ≈ 1.464, -5.464
