(x-2) + (x-1) + x + (x+1) + (x-2) + (x+3) = 447
6x + 3 = 447
6x = 447 - 3
6x = 444
x = 444/6
x = 74
The tan(-x) is the same thing as -tan(x). The tangent function is also the same thing as sin(x)/cos(x), right? So let's rewrite that tan in terms of sin and cos:
![[cos(x)][tan(-x)]](https://tex.z-dn.net/?f=%5Bcos%28x%29%5D%5Btan%28-x%29%5D)
is the same as
![[cos(x)][ -\frac{sin(x)}{cos(x)}]](https://tex.z-dn.net/?f=%5Bcos%28x%29%5D%5B%20-%5Cfrac%7Bsin%28x%29%7D%7Bcos%28x%29%7D%5D%20)
We can now cancel out the cos(x), which leaves us only with -sin(x) remaining. So your answer is A.
You have to expand the expression so that it becomes
3m+3n
Answer:100 ml/hr
Step-by-step explanation:
client has orders to receive 2 liters of IV fluid over a 24-hour period
½ this amount to be infused in the first 10 hours of treatment = ½ ×2 lires
= 1 litre =1× 000 ml= 1000ml
If 1000 ml is received in 10hrs
x ml will be received in 1 hrs
x = 1× 1000/10
= 100ml per hr
