Answer: 19.4
Step-by-step explanation:
Given
Profit is given in terms of the selling price
to get the maximum price, differentiate y w.r.t x
Put 
to get maximum value
Thus, the company must sell it at 19.4
Answer:
answer 1, 135
Step-by-step explanation:
Well, the X component (assuming x is the horizontal) is equal to RCosZ
Where Z is the angle and R is the size of the resultant
Substitute into formula :
X component = RcosZ
-3 = Rcos135°
R = -3/cos135°
R = 4.24264...
R = 4.24 (2dp)
The vertical component (or Y component) is equal to RSinZ
Vertical component = RSinZ
= 4.24264... × Sin135°
= 3
The answer is 3
Please feel free to ask any questions you have
by solving the first equation you'll get x= -24/13
if you solve the second option (B) then you'll the same result i.e x=-24/13
so option C is correct
