Take a warm shower, however you want, dont eat too much before hand, relax your face and don’t think too much about it, dont think much just think “im sleepy im going to sleep”
Incase you don’t want to read all of this
It seems like you’re stressed especially since you’re thinking about it too much to the point you have to use brainly. You’re stressed and need to relax and not think too much, you might be having too much things going around you and or many possibilities. For me I just take a warm shower and just stay and think, probably cry if i have to, without sleep or little you’re going to be anxious and things bother you more and makes sleeping even more harder on top of that
Answer:
-7°C
Step-by-step explanation:
Freezing point of water = 0°C
By adding salt, freezing point lowers by 7°C ;
The freezing point of salt water can be expressed as ;
Since temperature lowers :
Freezing point of salt water :
Freezing point of water - 7°C
0°C - 7°C
= - 7°C

Answer:
is an even function.
Step-by-step explanation:
Recall when it means when a function is even or odd. An even function has the following property:
And an odd function has the following property:
So, let's test some values for cos(x).
Let's use π/3:
From the unit circle, was can see that this is 1/2 (refer to the x-coordinate).
Now, let's find -π/3. This is the same as 5π/3. Thus:
And again from the unit circle, we can see that this is 1/2.
Therefore, despite the negative, the function outputs the same value.
Cosine is an even function.
Notes:
Cosine is an even function and sine is an odd function. It's helpful to remember these as they can help you solve some trig problems!
0 is the correct is answer only if x=3
