Step-by-step explanation:

Here we need to use Ohm's Law, because we have electric current, voltage and resistances. This law state:

So, first we need to calculate the total resistance to then find the voltage. The resistances can be placed in two ways: in parallel, in series.

The pair 4 and 8 ohms are parallel, so we solve:

Which is,

Now, this total resistance of parallels ones is placed in series with the 3 ohm resistance, in this case we just sum, because they are in series:

Now that we have the total resistance of the circuit, we use the Ohm's Law:

Therefore, the right answer is B.

1/4 because there is 4 grades.

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
