Given: sin θ = 0.8660 hypotenuse = 0.25 Find: θ = (please explain).
Bad White [126]

Answer:

Given that

sinθ = 0.8660

⇒ sinθ = 0.8660 = √3/2

⇒ θ = sin⁻¹(√3/2)

⇒ θ = 60°

In a reapeating musical pattern, there are 56 beats in 7 measures
anygoal [31]

Answer:

You will need to find the number of measures per beat (it will be a fraction): 7/56=0.125 Then, you multiply that by 104: 0.125x104=13 This means that there will be 13 measures after 104 beats.

Step-by-step explanation:

104 beats is multiplied with the decimal of the fraction of beats and measures which means it has been used with whole numbers

0.125 is not a whole number we know x 100 is 12.5 and we know x4 is 0.5

When we work with the first 4 multiples we can usually spot whether it would take more than 4 to round figure it to 0.5 to add to 12.5

There are 3 digits as decimals and x 100 quantifies.  just by adding 4 to x100 to each of them until a whole number found 12.5 + 0.5 = whole number = 13.

Linear Algebra: Permutation Matrices Let M be the matrix {{0,0,0,1,0}, {0,0,1,0,0}, {0,1,0,0,0}, {0,0,0,0,1}{1,0,0,0,0}}. What i
FromTheMoon [43]

Multiplying M by any matrix A would return new matrix, B, in which

• the 1st row of B is equal to the 4th row of A,

• the 2nd row of B is equal to the 3rd row of A,

• the 3rd row of B is equal to the 2nd row of A,

• the 4th row of B is equal to the 5th row of A, and

• the 5th row of B is equal to the 1st row of A.

The pattern here is

1 => 4 => 5 => 1

2 => 3 => 2

Let {4, 3, 2, 5, 1} denote the matrix M, where each number refers to the row of the identity matrix, I.

Using this notation, the pattern above gives

M² = {5, 2, 3, 1, 4}

M³ = {1, 3, 2, 4, 5}

M⁴ = {4, 2, 3, 5, 1}

M⁵ = {5, 3, 2, 1, 4}

M⁶ = {1, 2, 3, 4, 5}

so that <em>n</em> = 6.

(Notice that the first cycle has length 3 and the second one has length 2; the minimum <em>n</em> needed here is then LCM(2, 3) = 6.)
