Answer:
arg (w)=π/4 and |w|=√2
Step-by-step explanation:
If z= x+iy is a complex number, then |z| is given by √ ( x²+y² ).
And the argument (z) is given by Ф = tan⁻¹ ( y/x ) where -π < x < π.
Now, in our case w= 1+i i.e. x=1 and y=1.
Therefore, arg (w) = tan⁻¹ (1/1) = π/4 and |w|=√ ( 1²+1² ) = √2 (Answer)
Answer:
3.6 hours
Step-by-step explanation:
Blake can do work in hours = 9
Blake can do a part of work in 1 hour = 
Ned can paint the same room in six hours.
Ned can do a part of work in 1 hour = 
They can do a part of work together in 1 hour = 
= 
Now they can do part of work in hour = 1
So, they can do whole work in hours = 
= 
Hence it will take 3.6 hours to paint the room if they work together.
<span>Answer:
P=27
Q=10
TC=280
TC=FC+VC
FC=30
VC=280-30=250
TR=Q*P=10*27=270
Profit=TR-TC=270 - 280= -10
In short-tun Bob should continue mow lawns because he covers fixed costs (overvice instead of loss -10 he would had loss amounting fixed costs - 250)
In long-run he should close production.</span>
