Step-by-step explanation:
Answer:
Any point N on line r maps to itself.
Step-by-step explanation:
Reflection is one of the examples of solid transformation in which a given point, segment, or figure is flipped over a reference point or line to produce its image. The distance of the object to the reference point or line is the same as the distance of its image to the point or line. And both have the same size, but different orientation.
The option that does not fully define a reflection is; any point N on line r maps to itself, because no image of point N is produced after the operation.
Answer:
y=3
Step-by-step explanation:
perpendicular line to Y-axis passing through any point (m,n) is of the form
y=n
so the answer is
y=3
Answer:
total resistance is 54.54 ohms
Step-by-step explanation:
In parallel circuits, current can take various paths so the resistance are not added simply like that in series circuit, instead the reciprocal of total resistance in parallel circuit is calculated by adding the reciprocals of all the resistors connected parallel in circuit.
Given:
Resistor r1= 100
resistor r2 = 200
resistor r3= 300
The three resistors are connected in parallel so the total resistance will be calculated by:
1/R= 1/r1 +1/r2 +1/r3
Putting the values of r1, r2, r3 in above we get
1/R= 1/100 + 1/200 +1/300
= 0.01 + 0.005 + 0.0033
= 0.0183
Taking reciprocal of both sides:
R=54.54
Hence total resistance is 54.54 ohms!
