Answer:
A
Step-by-step explanation:
The formula that relates current, power and resistance is

Where
I is the current (in amperes)
P is the power (in watts)
R is the resistance (in ohms)
We know P = 500 and R = 25, we plug them into the formula and solve for I:

Correct answer is 4.47 Amperes, or choice A.

Area of polygon = (number of sides × length of one side × apothem)/2
<u><em>The third one is correct.</em></u> You cannot figure it out from the parent function, |x|, because they are all the same. As a result, you have to figure it out from the y-intercept. The y-intercept of a function most of the time is the <em>constant</em> of the function. The y-intercept here is <em>0.5</em>. Using this, you can find the corresponding graph. That would be the <u><em>third </em></u><u><em /></u><em /> option.
