[tex] \cos( \frac{5\pi}{12} ) = \cos( \frac{6\pi}{12} - \frac{\pi}{12} ) = \\ [/tex]
[tex] \cos( \frac{\pi}{2} - \frac{\pi}{12} ) = \sin( \frac{\pi}{12} ) \\ [/tex]

Also we have :

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
So :
[tex] \cos( \frac{\pi}{12} ). \sin( \frac{\pi}{12} ) + \sin( \frac{\pi}{12} ) . \cos( \frac{\pi}{12} ) = \\ [/tex]
[tex]2 \sin( \frac{\pi}{12} ) . \cos( \frac{\pi}{12} ) \\ [/tex]

Hint :
[tex] \sin(2 \alpha ) = 2 \sin( \alpha ) . \cos( \alpha ) [/tex]
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
So ;
[tex]2 \sin( \frac{\pi}{12} ) . \cos( \frac{\pi}{12} ) = \\ [/tex]
[tex] \sin(2 \times \frac{\pi}{12} ) = \sin( \frac{\pi}{6} ) \\ [/tex]

True or False? The blue radius is perpendicular to the green chord.
Answers
The statement that the blue radius is perpendicular to the green cord is false
From the complete question,
The blue radius does not bisect the green chord
This means that the blue radius and the green chord do not meet at 90 degrees
Since both lines do not meet at 90 degrees, then they are not perpendicular
Hence, the statement that the blue radius is perpendicular to the green cord is false

Diane earns $14,500 a year. She pays 11% of her gross income for federal, state, and local taxes. She is taxed at the FICA rate of 7.65%. She has 3.5% of her income withheld for personal deductions. She is paid biweekly. What is her net pay for each pay period? Round to nearest cent.
Answers
Answer:
$434.16346
Step-by-step explanation:
Given that :
Gross earning= $14500
Federal, state and local taxes = 11%
0.11 * $14500 = $1595
FICA tax rate = 7.65%
0.0765 * 14500 = $1109.25
Personal deduction :
3.5% * 14500
0.035 * 14500 = $507.50
Total deduction :
$(1595 + 1109.25 + 507.50)
= $3211.75
Net earning : $(14500 - 3211.75) = 11288.25
Since she is paid bi weekly:
Number of biweeks in a year = 52 /2 = 26
Number of payments per annum = 26
Hence,
Net pay per period :
11288.25 / 26
= $434.16346

Give me the answer in i will give you brainliest
Answers
Step-by-step explanation:
Given that,
The length of a baseball is 29 inches
Logan thinks he can bring the baseball bat home in his suitcase.
The length of the suit case is 24 inches while the height is 18 inches. We can find the diagonal (x) of the suitcase using Pythagorean Theorem as follows :
[tex]x^2=24^2+18^2\\\\x=\sqrt{900} \\\\x=30\ \text{inches}[/tex]
The diagonal of the suitcase is 30 inches. It means that he can put the baseball bat in the suitacse easily.
Triangles ABC and d e f are similar the lengths of the sides of ABC are 56/64 and 72 the length of the largest side of d e f is 252 what is the length of the smallest side of d e f
Answers
Answer:
[tex]D E F = 196[/tex]
Step-by-step explanation:
Given
[tex]ABC = 56, 64\ and\ 72[/tex]
[tex]Largest\ of\ D E F = 252[/tex]
Required
Determine the smallest side of DEF
Since both sides are similar, then the sides of DEF can be calculated using:
[tex]D E F = k * ABC[/tex]
First, we need to solve for k
From the given parameters
[tex]D E F = 252[/tex] when [tex]ABC = 72[/tex]
This is so because these are the largest sides of both triangles respectively
[tex]D E F = k * ABC[/tex]
[tex]252 = k * 72[/tex]
Divide through by 72
[tex]252/72 = k * 72/72[/tex]
[tex]k=252/72[/tex]
[tex]k=3.5[/tex]
We make use of the same formula to determine the length of the smallest side.
The smallest of ABC is 56, so we have:
[tex]D E F = k * ABC[/tex]
[tex]D E F = 3.5 * 56[/tex]
[tex]D E F = 196[/tex]
Hence, the smallest side of DEF is 196
