Step-by-step explanation:
2sin(x)cos(x) - sin(x) + 2cos(x)-1= 0
<=> sinx( 2cosx -1) + ( 2cosx -1) =0
<=> (sinx +1) + ( 2cosx-1)=0
<=> sinx=-1 or cosx= 1/2
+) sinx=1 => x= pi/2 + k×2pi
+)cosx=1/2 => x= pi/3+ k×2pi or x=-pi/3 + k×2pi
x€ [0,2pi] => x= pi/2, pi/3.
Answer:
The answer is :60
Step-by-step explanation:
Hmmmm...... because
The approximate distance between point p and q are 5.1 so the answer is D.
If each case weighs 24 pounds, then 1p=24 pounds. so if we're trying to find a function of weight, p=24c.
Example: When you have 2 cases, you plug in a 2 for c
p=24c
p=24(2)
p=48
So if you have two cases, it will total 48 pounds,
So that is why the equation is p=24c. Hope this helps!
