Two circles have a scale factor of 3:2. What is the ratio of the circumferences of these circles? A. 12:26
B. 13:12
C. 9:4
D. 3:2

3:2

Step-by-step explanation:

The circumference is a distance.  The ratio of the distance is the same as the scale factor.  The ratio of the areas is the ratio of the scale factor squared and the volume is the scale factor cubed.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
