The price of the Xbox One after tax is $265
<h3><u>Solution:</u></h3>The price of a Xbox one is $250
The tax on Xbox one is 6%
Now, the tax of 6% on 250 is calculated as follows:-
So, the tax on Xbox one is $15
The total price of box including tax can be calculated by adding price of box and tax on box
<em>Total price of Xbox after tax = actual price of the Xbox One + Tax on the Xbox One </em>
= $250 + $15
= $265
Hence, the price of the Xbox One after tax is $265
Answer:
The axis of symmetry is at
The graph has an x-intercept at
The graph has a vertex at
Step-by-step explanation:
we have
Statements
case 1) The graph has root at and
The statement is False
Because, the roots of the quadratic equation are the values of x when the value of y is equal to zero (x-intercepts)
Observing the graph, the roots are at and
case 2) The axis of symmetry is at
The statement is True
Observing the graph, the vertex is the point
The axis of symmetry in a vertical parabola is equal to the x-coordinate of the vertex
so
the equation of the axis of symmetry is
case 3) The graph has an x-intercept at
The statement is True
see procedure case 1)
case 4) The graph has an y-intercept at
The statement is False
Because, the y-intercept is the value of y when the value of x is equal to zero
Observing the graph, the y-intercept is the point
case 5) The graph has a relative minimum at
The statement is False
Because, is a vertical parabola open downward, therefore the vertex is a maximum
The point represent the vertex of the parabola, so is a maximum
case 6) The graph has a vertex at
The statement is True
see the procedure case 5)
see the attached figure to better understand the problem
Answer:
Since g(x) = f(2x), this means we substitute 2x in place of x for f(x):
g(x) = f(2x) = (2x)² = 4x²
Graphing this, the parabola is not moved from the parent graph f(x) = x², but the graph is compressed horizontally by a factor of 4.Step-by-step explanation:
