The correct answer is option 1
Answer:
C) π/6
Step-by-step explanation:
The area under the curve from x=-π/2 to x=k is 3 times the area under the curve from x=k to x=π/2.
![\int\limits^k_{-\frac{\pi }{2}} {cos\ x} \, dx = 3\int\limits^{\frac{\pi }{2}}_k {cos\ x} \, dx\\sin\ x\ |^{k}_{-\frac{\pi }{2}} = 3\ sin\ x\ |^{\frac{\pi }{2}}_k\\(sin\ k - (-1)) = 3\ (1 - sin\ k)\\sin\ k + 1 = 3 - 3\ sin\ k\\4\ sin\ k = 2\\sin\ k = \frac{1}{2}\\k = \frac{\pi}{6}](https://tex.z-dn.net/?f=%5Cint%5Climits%5Ek_%7B-%5Cfrac%7B%5Cpi%20%7D%7B2%7D%7D%20%7Bcos%5C%20x%7D%20%5C%2C%20dx%20%3D%203%5Cint%5Climits%5E%7B%5Cfrac%7B%5Cpi%20%7D%7B2%7D%7D_k%20%7Bcos%5C%20x%7D%20%5C%2C%20dx%5C%5Csin%5C%20x%5C%20%7C%5E%7Bk%7D_%7B-%5Cfrac%7B%5Cpi%20%7D%7B2%7D%7D%20%3D%203%5C%20sin%5C%20x%5C%20%7C%5E%7B%5Cfrac%7B%5Cpi%20%7D%7B2%7D%7D_k%5C%5C%28sin%5C%20k%20-%20%28-1%29%29%20%3D%203%5C%20%281%20-%20sin%5C%20k%29%5C%5Csin%5C%20k%20%2B%201%20%3D%203%20-%203%5C%20sin%5C%20k%5C%5C4%5C%20sin%5C%20k%20%3D%202%5C%5Csin%5C%20k%20%3D%20%5Cfrac%7B1%7D%7B2%7D%5C%5Ck%20%3D%20%5Cfrac%7B%5Cpi%7D%7B6%7D)

I'm pretty sure it's Identity I hope it helps :)
Hello.
First of all, let the number be t.
8 times t can be written like this:
![\mathrm{8t}](https://tex.z-dn.net/?f=%5Cmathrm%7B8t%7D)
Notice that the number is before the variable and the times sign (×) is not there.
We can write it as 8×t, but we usually write it as 8t.
The sum of means we add:
8t+21
Now, "less than" is "<" :
![\mathrm{8t+21 < -16}](https://tex.z-dn.net/?f=%5Cmathrm%7B8t%2B21%20%3C%20-16%7D)
Therefore, the answer is
![\mathrm{8t+21 < -16}](https://tex.z-dn.net/?f=%5Cmathrm%7B8t%2B21%20%3C%20-16%7D)
I hope it helps.
Have a nice day.
