Answer:

B. The ratio of the area of the scale drawing to the area of the painting is 1:16

C. The ratio of the perimeter of the scale drawing to the perimeter of the painting is 1:4

Step-by-step explanation:

The ratio of the area of similar figures/shapes = the square of the ratio of any of their side lengths

Since the scale drawing of the rectangular painting and the actual rectangular painting are similar, therefore,

The ratio of the area of the scale drawing to the painting = 1²:4²

= 1:16

Also, comparing the ratio of the perimeter of the scale drawing to the perimeter of the painting will be the same as the scale factor = 1:4

Y = x² + 6x + 3
olganol [36]

Vertex<em> </em>is at \left(-3,-6\right)

<em>y-intercept</em> is 3.

The parabola <em>opens up</em>.

Step-by-step explanation:

The graph of the equation is hereby attached in the answer area.

Vertex is the point on the parabola where the graph crosses its axis of symmetry. The axis of symmetry here(x =-3), is shown with the dotted line in the graph attached.

<em>y-intercept </em>is defined as the value of y where the graph crosses the y-axis. In other words, when x=0. Putting

And, the graph opens up as shown the graph figure as well. It is also evident from the co-efficient of x in the given equation y =x^{2} + 6x + 3. Here, co-efficient of

So, vertex<em> </em>is at \left(-3,-6\right)

<em>y-intercept</em> is 3.

The parabola <em>opens up</em>.
