Answer:
C - 1 / sin^2x
Step-by-step explanation:
as csc x = 1 / sin x
so, csc^2 x = 1 / sin^ 2x
Answer:
7![\frac{1}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D)
Step-by-step explanation:
the reciprocal of ![\frac{1}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B3%7D)
To find reciprocal, flip the top and the bottom.
So
would be
.
Multiply like normal.
For this case we have the following expression:
<span>
![(-4)(-4) ](https://tex.z-dn.net/?f=%28-4%29%28-4%29%20%0A)
By properties of exponents we have:
Same basis, the exponents are added.
We have then:
![(-4)^{1+1}](https://tex.z-dn.net/?f=%28-4%29%5E%7B1%2B1%7D)
Then, rewriting the exponent we have:
![(-4)^{2}](https://tex.z-dn.net/?f=%28-4%29%5E%7B2%7D)
Therefore, an exponent to rewrite the expression is:
2
Answer:
an exponent to rewrite the expression is 2.</span>
Well since there was 560 students the it was 560/560. now that 50 got selected the total portion would be 560/6
