Answer:
5x +3y = -14
Step-by-step explanation:
The equation of the given line is in standard form. This makes it easy to write the equation for a perpendicular line.
__
<h3>form</h3>
The perpendicular line will have a slope that is the negative reciprocal of the slope of the given line. This can be made to happen by ...
- swapping the coefficients of x- and y
- negating one of the coefficients.
So, the line perpendicular to 3x -5y = 2 will have an equation of the form ...
5x +3y = c . . . . . for some constant c
<h3>constant</h3>
The constant will be what is needed to make the line go through the given point. That is, for (x, y) = (-1, -3), the equation is satisfied.
5(-1) +3(-3) = c = -5 -9 = -14 . . . . . substitute values for x and y
<h3>equation</h3>
Then the equation for the perpendicular line through (-1, -3) is ...
5x +3y = -14
We have the Voltage v = 80 volts
Current i = 40 amps
We need to find the resistance r
The Ohm's law states that the current in any circuit is directly proportional to the voltage and inversely proportional to the resistance
which gives the formula
or
lets plug in our values
Resistance is measured in ohm denoted by the symbol Ω
Hence the answer is 2Ω or 2 ohms
One solution. Hope this helps!
