Mathematics

Answer:

1)Clear parenthesis on both sides of the inequality and collect like terms.

2)Add or subtract terms so the variable is on one side and the constant is on the other side of the inequality sign.

3)Multiply and divide by whatever constants are attached to the variable.

Step-by-step explanation:

The area of this rectangle is given by the quadratic function
Sonja [21]

<em>The function uses W as the variable but the options show only x's as the variable, so I'm asumming W in the answer</em>

Answer:

0 < W < 50

Correct option: A

Step-by-step explanation:

<u>Domain of functions</u>

Some functions have restricted values of the independent variable x. It can be due to mathematical restrictions, like dividing by 0 or taking the square root of a negative number, of it can be due to practical conditions of the situation being modeled.

In this case, the area of a rectangle is given by the quadratic function.

A=50W - W^2

Since the area of a rectangle cannot be negative (and should be positive, though it could be zero), the practical domain of A is determined when

50W - W^2\geq 0

Taking common factor W

W(50 - W)\geq 0

Since W must be positive W>0

50 - W\geq 0

Or equivalently

50 \geq W

W \leq 50

The total interval is

0 < W

Correct option: A

Please note: The real restriction should be

0 < W\leq 50

if we allowed the area to be positive, but I'm providing the most possible correct available option
