Answer:
m=2
Step-by-step explanation:
We are given a line y=mx-7 and the point lying on the given line is (3,-1) in the standard {x,y} coordinate plane.
Therefore, substituting the values of x=3 and y=-1 in the given line, we have,
⇒
⇒
⇒
⇒
⇒
Hence,the value of m will be equal to two.
Answer:
Total Resistance = Ω (or 144.44 Ω)
Step-by-step explanation:
If two resistors, with resistance x and y, are connected in parallel, their total resistance is given by the formula:
If 2 resistors with resistance x and y and connected in series, their total resistance would be:
Total = x + y
<em>Now, the first part, 100 and 80 are in parallel, so according to formula it would be:</em>
<em></em>
<em />
<em>Now, this is connected in series with 100, so the grand total would be:</em>
<em>Total Resistance of Circuit = </em>
<em />
This is the total resistance of the circuit.
