Given:

The graph of a parabola.

To find:

The equation of the parabola.

Solution:

From the given graph, it is clear that the vertex of the parabola is at point (0,0) and it is a horizontal parabola.

The general equation of a horizontal parabola is:

x=ay^2

Where, a is a constant.

If a<0, then the parabola opens left and if a>0, then the parabola opens right.

Equations in options B and D are of the form x=ay^2 but a<0 in option B and a>0 in option D.

In the given graph the parabola opens right, so the value of a mus be a positive number. So, the required equation is:

x=\dfrac{1}{6}y^2

Therefore, the correct option is D.

21 feet / 3 ft = 7 yards

12 feet  / 3 feet = 4 yards

7 x 4 = 28 square yards

he will need 28 tiles

Line L is mapped onto line m by a dilation centered at the origin with a scale factor of 2/5. Line m is represented by y=2x+10 a
Alinara [238K]

Dilating a line changes the size of the line.

The true statement is <em>(c) Line L passes through the origin</em>

The scale of dilation is given as:

\mathbf{k = \frac 25}

The scale represents the slope of line L.

The equation of line M is:

\mathbf{y = 2x + 10}

From the above equation, the slope of line M is:

\mathbf{m = 2}

The two lines do not have the same slope.

<em>This means that, the lines are not parallel and they are not the same line.</em>

<em />

For the two lines to be perpendicular, then the relationship between their slopes is:

\mathbf{m = -\frac 1k}

The above is false, because:

\mathbf{2 \ne -\frac 52}

Hence, the true statement is <em>(c) Line L passes through the origin</em>

<em />
