Answer:
To find the peak value of a sinusoidal alternating current given its RMS (Root Mean Square) value, you can use the relationship between peak value and RMS value for a sinusoidal waveform.
The relationship is given by:
Peak Value = RMS Value * √2
In this case, the RMS value is 4.78 amp. Plugging this into the equation, we get:
Peak Value = 4.78 amp * √2 ≈ 6.76 amp
Therefore, the correct answer is option b) 6.76 amp.

Step-by-step explanation:
ok so the y-axis is the one that goes down, so basically you want to draw the line how it is but like a how mirror does it.
Answer:
y=9
Step-by-step explanation:
6.4x + 2.8y = 44.4
x=3, y=?
Answer:
9
Step-by-step explanation:
6.4x + 2.8y = 44.4
x=3, substituting it in the expression above we have :
6.4(3) + 2.8y = 44.4
19.2 + 2.8y = 44.4
2.8y = 44.4 -19.2 = 25.2
y = 25.2 / 2.8 = 9
Answer:
Alaina got 4, Miguel got 2(4) = 8 while Kira got 2(8) = 16
Step-by-step explanation:
Let the number he gave to Alaina be x. Now, we know he gave twice as many to Miguel. Amount received by Miguel is 2x.
He gave Kira 2 times what he gave Miguel, that is 2x * 2 = 4x
Addition of all these equals 28. We now get x
4x + 2x + x = 28
7x = 28
X = 28/7
x = 4
Alaina got 4, Miguel got 2(4) = 8 while Kira got 2(8) = 16
Answer:
x= 25+20y
Step-by-step explanation:
De acuerdo a la situación planteada, la expresión algebraica debe indicar que 25€ que es el valor por la visita más 20€ multiplicado por el número de horas trabajadas es igual al dinero total que se debe pagar. La expresión es:
x= 25+20y, donde
x= valor total a pagar
y= número de horas trabajadas
Answer:
Allentown(x) got 8 feet of snow and Georgetown(y) got 3 feet of snow
Step-by-step explanation:
Allentown got 2 feet less than twice the amount of snow Georgetown got . Allentown got 3 feet more snow than Georgetown.
Allentown = x and Georgetown=y
To solve this we need to represent this information mathematically;
'Allentown got 2 feet less than twice the amount of snow Georgetown got' can be written mathematically as; x = 2y - 2
and
'Allentown got 3 feet more snow than Georgetown' can be mathematically written as x = y + 3
x= 2y - 2 ----------------------(1)
x = y + 3 --------------------------(2)
Subtract equation (2) from equation (1)
[ x-x=0 2y-y = y -2-3=-5]
0 = y - 5
To get the value of y, add 5 to both-side of the equation
0+ 5 = y-5+5
5=y
y=5
Substitute y=5 into equation (2)
x = y+3
x=5+3
x=8
Therefore Allentown(x) got 8 feet of snow and Georgetown(y) got 3 feet of snow
x=2y-2
x=y+3
Substitute the second equation into the first
y+3=2y-2
solve for y
y=5
plug into original
x=y+3=5+3=8 or x=2(5)-2=8
Allentown got 8 ft of snow, Georgetown got 5 ft of snow.
