<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.
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
Taking common factor W
Since W must be positive W>0
Or equivalently
The total interval is
Correct option: A
Please note: The real restriction should be
if we allowed the area to be positive, but I'm providing the most possible correct available option
Answer:
B) 7v^3-15v^2-17v-3
Step-by-step explanation:
(v-3)(7v^2+6v+1)
7v^3+6v^2+v-21v^2-18v-3
7v^3+6v^2-21v^2+v-18v-3
7v^3-15v^2-17v-3
Answer:
Step-by-step explanation:
Graph of x=5 is vertical straight line parallel to y-axis and perpendicular to x-axis. The points on graph have the x-coordinate as 5 and y-coordinate varies.
Similarly, line parallel to x=5 or y-axis passing through point (-6,6), in that all the points have same x-coordinate as -6. So the equation of line will be x=-6
For simplicity of visualization graph of both the equation x=5 and x=-6 are attached.
