Answer:

The answer to your question is: AC = 36

Step-by-step explanation:

Data

Segment AC with midpoint = B

AC = 5x - 9

AB = 2x

AC = ?

Process

total length = AC but B is the midpoint so AB + AB = CA

2AB = CA

Substitution 2(2x) = 5x - 9

4x = 5x - 9

Solve for x 4x - 5x = -9

-1x = -9

x = -9/-1

x = 9

Finally, AC = 5x - 9

= 5(9) - 9

= 45 - 9

= 36

NemiM [27]

Answer: The length of the second arc is 12 feet.

Step-by-step explanation:

Since we know that

A rope is swinging in such a way that the length of the arc is decreasing geometrically,

Length of first arc = 18 feet

Length of third arc = 8 feet

Let the length of second arc be x

As we know that

$\frac{a_2}{a_1}=\frac{a_3}{a_2}\\\\\frac{x}{18}=\frac{8}{x}\\\\x^2=18\times 8\\\\x^2=144\\\\x=\sqrt{144}\\\\x=12$

Hence, the length of the second arc is 12 feet.
