The two triangles are similar if the ratio of the corresponding sides are proportional.
The ratio of the corresponding sides are:
The set of ratios which could be used to determine if one triangle is a dilation of the other is
If there are multiple correct options then check this one too.
Answer:
Step-by-step explanation:
Consider a sketch of the problem as shown in the picture, where:
Since the center of the circle lies on the line y = 4x +1 and is tangent to the x-axis at point A, then its radius BA is perpendicular to the x-axis. To find the coordinates of point B, we must replace x = -3 into the blue line equation: y = 4x(-3) + 1 = -11.
So, we know that the center of the circle is at B=(-3, -11). And furthermore, the radius BA is of length r=11.
Since the <em>general equation of the circle</em> of radius lenght r centered at (h, k) is given by
then with h = -3, k = -11 and r= 11, the equation of our circle is
