The required value of the trigonometric operator tan(π/12) = 2 -√3. None of them is correct.
These are the equation that contains trigonometric operators such as sin, cos.. etc. In algebraic operation.
Let,
= [tex]tan(\pi /12) = tan((3-2)\pi /12)[/tex]
[tex]= tan[(3\pi -2\pi )/12]\\=tan(3\pi /2-2\pi /12)\\=tan(\pi /4-\pi /6)\\=\frac{tan(\pi/4)-tan(\pi/6)}{1+tan(\pi/4)tan(\pi/6)}[/tex]
= [tex]\frac{1-1/\sqrt{3} }{1+1*1/\sqrt{3} } \\[/tex]
[tex]=\frac{(\sqrt{3}-1)/\sqrt{3}}{(\sqrt{3}+1))/\sqrt{3}}[/tex]
[tex]=\frac{(\sqrt{3}-1)}{(\sqrt{3}+1)}\\=\frac{(\sqrt{3}-1)(\sqrt{3}+1)}{(\sqrt{3}+1)(\sqrt{3}+1)}\\=\frac{(3-2\sqrt{3}+1)}{(3-1)}\\\\=\frac{(4-2\sqrt{3})}{(2)}\\={(2-\sqrt{3})}\\[/tex]
Thus, the required value of the trigonometric operator tan(π/12) = 2 -√3. None of them is correct.

Answer: y = 90 degrees.
Step-by-step explanation: We are given that the supplementary angle of angle y is equal to 90 degrees. By definition, that means that y is also equal to 90 degrees. The solution would be:
y + 50 degrees + 40 degrees = 180 degrees
y + 90 degrees = 180 degrees
y = 180 degrees - 90 degrees
y = 90 degrees

Which table represents y as a function of x?
Answers
Answer:
Table number 1
Step-by-step explanation:
explanation: If the X-inputs (the exes) repeats then the table is not a function.
In the first table all the x-inputs are different.
Hence, table first is the correct answer which [tex]y[/tex] is a function of [tex]x[/tex].
What is a input ?
The input is what goes into the function and the output is what comes out of the function.
Here as per the information, table first is correct because when the values [tex]x[/tex] change then it is a function of [tex]y[/tex] , and as per this concept table first is correct.
Hence, table first is the correct answer which [tex]y[/tex] is a function of [tex]x[/tex].

Step-by-step explanation:
The interior angles of a triangle will always add up to 180°, so all we have to do is find the missing variable.
To do this, we first add up the two angles we do know.
—> 65 + 40 = 105
Now that we have the total of the other two angles, simply subtract 105 from 180.
—> 180 - 105 = 75
We now have our answer!

(its hard to explain but you need to spit 1356 and add 284 to one half)
Answer:
820
Step-by-step explanation:
Let us call the trip back x. The trip back is 284 miles smaller than the trip back, so our equation can be:
x + x + 284 = 1356
2x + 284 = 1356
2x = 1072
x = 536
The we do 536 + 284 because the trip there was 284 miles longer, so that is 820
A talet weighs 2.22... pounds. What is the tablet's weight written as a mixed number fraction ?
Answers
Answer:
2 11/50
Step-by-step explanation:
Convert to a mixed number:
111/50
Hint: | Use long division to get a quotient and remainder.
Divide 111 by 50:
5 | 0 | 1 | 1 | 1
Hint: | How many times does 50 go into 111?
50 goes into 111 at most 2 times:
| | | | 2
5 | 0 | 1 | 1 | 1
| - | 1 | 0 | 0
| | | 1 | 1
Hint: | Summarize the results.
Read off the results. The quotient is the number at the top and the remainder is the number at the bottom:
| | | | 2 | (quotient)
5 | 0 | 1 | 1 | 1 |
| - | 1 | 0 | 0 |
| | | 1 | 1 | (remainder)
Hint: | In the equivalent mixed fraction, the quotient becomes the whole number part, the remainder becomes the numerator part, and the divisor (denominator) remains the denominator.
The quotient of 111/50 is 2 with remainder 11, so:

Answers
Answer:
A:59 B:48
Step-by-step explanation:
A triangle is equal to 180 degrees. So the equation would be
73+x+(x-11)=180. To find the value of x, add all of the same values
73-11+x+x which is equal to 62+2x=180. Then subtract 62 from both sides
62-62+2x=180-62 so the equation is now 2x=118 now you divide each side by 2 to get x=59. now to get angle b you subtract 11 from 59 to get 48

2300 people came to the ball game last week. This week there was a 13% decrease. How many people attended the football game this week. The problem can be represented by the expression p-0.13p.
Answers
Answer: 2001 people attended the football game this week.
Step-by-step explanation:
Given: Total people came to the ball game = 2300
Decrease percent = 13%
Number of people attended the football game this week = p-0.13p, where p= number of people attended football last week.
for p= 2300
Number of people attended the football game this week = 2300- 0.13 x (2300)
=2300- 299
= 2001
hence, 2001 people attended the football game this week.
