Answer: D. Two or zero
Step-by-step explanation: x=-7/6+-1/6√385
There isn't an exact place you could really solve this number, regardless of the way you break it down
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.
