Answer:
Given the expression: ![\sin^{-1}(\cos(\frac{\pi}{2}))](https://tex.z-dn.net/?f=%5Csin%5E%7B-1%7D%28%5Ccos%28%5Cfrac%7B%5Cpi%7D%7B2%7D%29%29)
Let the value of the given expression in radians be ![\theta](https://tex.z-dn.net/?f=%5Ctheta)
then;
![\sin^{-1}(\cos(\frac{\pi}{2})) =\theta](https://tex.z-dn.net/?f=%5Csin%5E%7B-1%7D%28%5Ccos%28%5Cfrac%7B%5Cpi%7D%7B2%7D%29%29%20%3D%5Ctheta)
......[1]
We know the value of ![\cos \frac{\pi}{2} = 0](https://tex.z-dn.net/?f=%5Ccos%20%5Cfrac%7B%5Cpi%7D%7B2%7D%20%3D%200)
Substitute the given value in [1] we have;
![\sin \theta = 0](https://tex.z-dn.net/?f=%5Csin%20%5Ctheta%20%3D%200)
Since, the value of
is 0, therefore, the value of
is in the form of:
; where n is the integer.
At n =0, 1 and 2, {Since, n is the integer}
Value of
and
therefore, the answer in radians either
or

Answer:
31.
Step-by-step explanation:
1. Write out the problem.
6w-19 + k; w=8 and k=2
2. Figure out the first part of the problem.
So, if w=8 and 6 and w are next to each other, we should multiply 6*8, which is 48. Next, it says to subtract 19. 48-19=29.
3. Find out what the last part of the problem is.
Since the first part of the problem is 29 and k=2, we should add 29+2=31, which is the final answer.
Hope this helped :)
Answer:
Hey there!
The first equation has no solutions, as it is parallel lines.
The second equation has infinitely many solutions, as it is basically the same line, and the two lines intersect at infinite points.
The third equation is just one solution.
Let me know if this helps :)
You'd need to find the distance AROUND the garden, which is also PERIMETER.
To find the perimeter of a circle, you use the following equation:
![2 \pi (4)](https://tex.z-dn.net/?f=2%20%5Cpi%20%284%29)
=
![8 \pi](https://tex.z-dn.net/?f=8%20%5Cpi%20)
![8 \pi](https://tex.z-dn.net/?f=8%20%5Cpi%20)
