Answer:
V = 4 volt
Step-by-step explanation:
Given: Electrical power (w) P = 0.5 watt and resistance R ( Ω ) R = 32 ohm
Voltage V = ? (volt)
Formula for calculating electrical power is:
P = V² / R => V² = P · R => V ) √P · R = √0.5 · 32 = √16 = 4 volt
V = 4 volt
God with you!!!
Ok... after much confusion, I've come to the conclusion that you must have written the question wrong and it's actually the perimeter that is 90 feet so that's how I'm going to work it...
Width = w
Length = 4w - 9
P = 2w x 2L
90 = 2w + 2(4w - 9)
90 = 2w + 8w - 18
90 = 10w - 18
108 = 10w
108/10 = w
10 4/5 = w
Width is 10 4/5 ft
Length = 4w - 9
L = 4(10 4/5) - 9
L = 43 1/5 - 9
L = 34 1/5 ft
Length 34 1/5 ft Width 10 4/5 ft or
Length 34.2 ft and width 10.8 ft
The answer is
56x-(23y)^9/3 = 42
I think the common denominator is 90. 8,9,and 10 can all go into 90.
