The electric heaters, in a 240 volt electric furnace, draw 40 amps of current. What is the total KW rating of the heaters?

expeople1 [14]

9514 1404 393

Answer:

9.6 kW

Step-by-step explanation:

The product of volts and amps is watts. Here, that product is ...

(240 V)(40 A) = 9600 W

1000 W is 1 kW, so this quantity is 9.6 kW

This tells the power consumption. The "rating" may be different.

forsale [732]

Answer:

495.6

Step-by-step explanation:

18% of 420 is 75.6. Multiply that by 63 to get 4762.8. 420 multiplied by 63 equals 26460. 26460 plus 4762.8 is 31222.8. 31222.8 divided by 63 is 495.6. So the answer is $495.60 per year.

Answer:

$e^x+xy+3y+(y-1)e^y=4$

Step-by-step explanation:

Given that

$(e^x+y)dx+(3+x+ye^y)dy=0$

Here

$M=e^x+y$

$N=3+x+ye^y$

We know that

M dx + N dy=0 will be exact if

$\frac{\partial M}{\partial y}=\frac{\partial N}{\partial x}$

$\frac{\partial M}{\partial y}=1$

$\frac{\partial N}{\partial x}=1$

it means that this is a exact equation.

$\int d\left(e^x+xy+3y+(y-1)e^y\right)=0$

Noe by integrating above equation

$e^x+xy+3y+(y-1)e^y=C$

Given that

x= 0 then y= 1

$e^0+0+3+(1-1)e^1=C$

C=4

So the our final equation will be

$e^x+xy+3y+(y-1)e^y=4$
