Answer:
The expression that represents
is
![\theta=arccos(\frac{x}{6})](https://tex.z-dn.net/?f=%5Ctheta%3Darccos%28%5Cfrac%7Bx%7D%7B6%7D%29)
Step-by-step explanation:
The trigonometric equation given to us is
![cos(\theta)=\frac{x}{6}](https://tex.z-dn.net/?f=cos%28%5Ctheta%29%3D%5Cfrac%7Bx%7D%7B6%7D)
We take the cosine inverse of both sides to obtain,
![arccos(cos(\theta))=arccos(\frac{x}{6})](https://tex.z-dn.net/?f=arccos%28cos%28%5Ctheta%29%29%3Darccos%28%5Cfrac%7Bx%7D%7B6%7D%29)
Recall that, the composition of a function of x and its inverse produces x.
That is
or
Similarly, ![arccos(cos(\theta))=\theta](https://tex.z-dn.net/?f=arccos%28cos%28%5Ctheta%29%29%3D%5Ctheta)
This implies that,
![\theta=arccos(\frac{x}{6})](https://tex.z-dn.net/?f=%5Ctheta%3Darccos%28%5Cfrac%7Bx%7D%7B6%7D%29)
The correct answer is C.
Answer:
I'd say multiply the numerators then the denominators and at the end simplify at least thats how I multiply fractions :)
Answer:
2804.671948
Step-by-step explanation:
1900(1+8.1%) exponent of 5
1900(1+8.1%)^ 5
Change the percent to a decimal
1900(1+.081)^ 5
1900 (1.081)^5
1900(1.039711498)
2804.671948
