Answer:
-8
Step-by-step explanation:
f(x) = 3x + 1
f(-3) = 3(-3) + 1
F(-3)=-9+1
f(-3)= -8
I think it would be to refute the counterclaim.
Hope this helps!
Answer:
R = sqrt[(IWL)^2/(E^2 - I^2)] or R = -sqrt[(IWL)^2/(E^2 - I^2)]
Step-by-step explanation:
Squaring both sides of equation:
I^2 = (ER)^2/(R^2 + (WL)^2)
<=>(ER)^2 = (I^2)*(R^2 + (WL)^2)
<=>(ER)^2 - (IR)^2 = (IWL)^2
<=> R^2(E^2 - I^2) = (IWL)^2
<=> R^2 = (IWL)^2/(E^2 - I^2)
<=> R = sqrt[(IWL)^2/(E^2 - I^2)] or R = -sqrt[(IWL)^2/(E^2 - I^2)]
Hope this helps!
I believe the answer is 267
If each is worth $25 and it costs $10 then he is making $15 profit.
4000/15 is 266.6666667
So you would need 267
