Option C
<u>Answer:
</u>
The current flowing through the circuit is 5 A
<u>Solution:
</u>
Given that resistance of an electric circuit is 12 ohms and the voltage in the circuit is 60 V.
We have to find the current flowing through the circuit.
By Ohms law, the relation between the resistance, voltage and current in the circuit is given as,
---- eqn 1
where, V = voltage in the circuit
I = current flowing through the circuit
R = resistance of the electric circuit
From question given that, R = 12 ohms; V = 60 V
By using eqn 1, the current flowing through the circuit is given as
Hence the current flowing through the circuit is 5A.
Just add a similar triangle from the opposite side
Then what happens
- Hypotenuse of this triangle becomes common and diagonal of the rectangle.
Now
Area
- Area of triangle=20/2=10units^2
I think it's 56y + 7, is what I'm pretty sure of.
Answer:
d.
Step-by-step explanation:
Left line is defined when x < 1 (x is less than 1). The point is not full and that means that x = 1 is not included.
Right line is defined when x is greater or equal to one x ≥ 1.
Options that have x < 1 and x ≥ 1 are b and d, so the answer is one of those.
Equations of the lines are in slope-intercept form y = mx + b, where m is slope and b is y-intercept.
Right line has steeper slope than left line, so the slope of right line will have bigger absolute value. That is the case with option d. (Left line has slope -1 and right one has slope -2, absolute value of right slope is bigger.)
You could also check with y-intercepts. Left line has y-intercept at y = 2 and left line is defined when x < 1. Only option d meets these conditions.
It will be irrational. The sum of any irrational and rational number will ALWAYS result in a irrational answer. Khan Academy has a video on this if you want to watch it.
