Answer:
![csc(\theta)=\frac{25}{7}](https://tex.z-dn.net/?f=csc%28%5Ctheta%29%3D%5Cfrac%7B25%7D%7B7%7D)
Step-by-step explanation:
We know that:
![sin(\theta)=\frac{7}{25}](https://tex.z-dn.net/?f=sin%28%5Ctheta%29%3D%5Cfrac%7B7%7D%7B25%7D)
And we want to find:
![csc(\theta)](https://tex.z-dn.net/?f=csc%28%5Ctheta%29)
Remember that there is a trigonometric identity that relates the
function with the
function
![csc(\theta)=\frac{1}{sin(\theta)}](https://tex.z-dn.net/?f=csc%28%5Ctheta%29%3D%5Cfrac%7B1%7D%7Bsin%28%5Ctheta%29%7D)
Then if
this means that:
![csc(\theta)=\frac{1}{\frac{7}{25}}](https://tex.z-dn.net/?f=csc%28%5Ctheta%29%3D%5Cfrac%7B1%7D%7B%5Cfrac%7B7%7D%7B25%7D%7D)
Finally:
![csc(\theta)=\frac{25}{7}](https://tex.z-dn.net/?f=csc%28%5Ctheta%29%3D%5Cfrac%7B25%7D%7B7%7D)
Answer:
C
Step-by-step explanation:
since we're being told to convert the ratio to fraction then it is C. note that 4 ratio is also the same as dividing 4 by 6
P(LC / S) = P(S intersect LC) / P(S)
P(S intersect LC) = P(S)*P(LC / S) = 0.19 * 0.158 = 0.03
Answer:
1.7 x 10^-27
Step-by-step explanation
Move the decimal to the right until it's a single digit number, because you are moving it to the right, it would be a negative number. If you are able to round up then please do. Remember to check your significant figures if you're in chemistry.
