Answer:
Solution : 8i
Step-by-step explanation:
We can use the trivial identities cos(π / 2) = 0, and sin(π / 2) = 1 to solve this problem. Let's substitute,
![8\left[cos\left(\frac{\pi }{2}\right)+isin\left(\frac{\pi \:}{2}\right)\right]](https://tex.z-dn.net/?f=8%5Cleft%5Bcos%5Cleft%28%5Cfrac%7B%5Cpi%20%7D%7B2%7D%5Cright%29%2Bisin%5Cleft%28%5Cfrac%7B%5Cpi%20%5C%3A%7D%7B2%7D%5Cright%29%5Cright%5D)
= 
And of course 1i = i, so we have the expression 8(0 + i ). Distributing the " 8, " 8( 0 ) = 0, and 8(i) = 8i, making the fourth answer the correct solution.
Let’s make common denominator
1/4 * 2/2 = 2/8 before dinner
1/8 after dinner
2/8 + 1/8 = 3/8
He finished 3/8 of the report
I'm relatively sure that it is 9 but idk rly. Hope this helps!
Answer:
B=fh
Step-by-step explanation:
I think?
Basically divided by b to get h over b and then times by h to get b=fh (you want to be get on its own)
Step-by-step explanation:
this is the anwser it is inverse trigonometry
