Answer:

Scale factor: 1.85714285714 or 1.86 (if rounded up)

Step-by-step explanation:

Since the lengths of the triangles are corresponding, you need to count how many lines each triangle measures to.

The small triangle is measured to 7 lines.

The bigger triangle is measured to 13 lines.

13/7 = 1.85714285714 but if rounded up, it's 1.86.

What is the radius of a circle whose equation is x2 + y2 + 8x – 6y + 21 = 0?

s344n2d4d5 [400]

Answer:

2 units

Step-by-step explanation:

The given equation of the circle is:

$x^{2} + y^{2}+8x-6y+21=0$

The general equation of the circle is:

$x^{2} + y^{2}+2gx+2fy+c=0$

Comparing the given equation with the general equation we can say:

g = 4

f = -3

c = 21

The formula for radius of the circle is:

$radius=\sqrt{g^{2} +f^{2} -c }$

Using these values of the given circle, we get:

$radius=\sqrt{(4)^{2}+(-3)^{2}-21}\\\\radius=\sqrt{4}\\\\radius=2$

Therefore, the length of radius of the given circle is 2.
