Answer:
y= (3/4) x - (3/2)
Step-by-step explanation:
3x - 4y = 6 (using algebra add the 4y to the other side & subtract the 6 to the other side >> 3x - 6 = 4y (then divide everything by 4 to get y by itself) >> 3/4x - 6/4 = y (then simplify) >> 3/4x - 3/2 = y
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!
Hey there!
3^3 * x^2 - 25 / 5
= 3^3 * 0.6^2 - 25 / 5
= 3 * 3 * 3 * 0.6 * 0.6 - 25 / 5
= 9 * 3 * 0.6 * 0.6 - 25 / 5
= 27 * 0.36 - 25 / 5
= 9.72 - 25 / 5
= 9.72 - 5
= 4.72
Therefore, your answer is: 4.72
Good luck on your assignment & enjoy your day!
