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.
The width of the walkaway be 4 feet.
<h3>What is Discriminant Formula?</h3>
The discriminant formula is used to determine the nature of the roots of a quadratic equation. The discriminant of a quadratic equation is D =
If D > 0, then the equation has two real distinct roots.
If D = 0, then the equation has only one real root.
Given that:
also, area of walkaway = 464 square feet.
So,
Using Discriminant method,
a=4, b=100, c=-464
w=
w=
So,
Hence the width of the walkaway be 4 feet.
