The pendulum of an antique clock has been damaged and needs to be

Dimas [21]

If the original pendulum completed one swing every 1.5 seconds. How long should the new pendulum be is: C. 55.9 centimeters.

<h3>How long should the new pendulum be</h3>

Using this formula

T=2π√I/g

Where:

T=1.5 seconds

l =length of pendulum

g= acceleration of gravity=9.8m/s²

Let plug in the formula

1.5 seconds=2π√I/9.8

l/9.8=0.05699

l=0.05699×9.8

l=0.5585

l=55.9 centimeters (Approximately)

Therefore How long should the new pendulum be is: C. 55.9 centimeters.

From an upstairs window, I can see my neighbor’s fence. The angle of depression is 7 degrees. If my window is 15 ft off the grou

Tresset [83]

Answer:

1.84ft

Step-by-step explanation:

From the figure attached,

AB = Height of the window = 15ft

Let the distance between the base of the housr and the fence 'C' = xft

If the angle of depression = 7°

Then angle of elevation of the top of the fence from the house = 7°

Now from right triangle ABC,

tan7° = x/15

x = tan7°×15

x = 0.1227×15

x = 1.84ft

Therefore, distance of the house from the fence is 1.84ft

Alina [70]

This question is intriguing. Shannon does something that involves
the rent, a route, and a rope. I'm having serious difficulty trying to
understand how these are related.

Solve ABC with B = 122°, b = 18 feet and c = 12 feet.

romanna [79]

Answer:

C = 34 degrees, A=8.6 feet

Step-by-step explanation:

Use sine law:

$\frac{sin122}{18} = \frac{sinC}{12}$

$sin^{-1} [12(\frac{sin122}{18})]= C$

C = 34 degrees

Now that you have the C and B degrees, solve for A degrees

180 - 34 - 122 = 24 degrees for angle A

Same way as above use sine law to find the side for a now:

$\frac{18}{sin122} = \frac{A}{sin24}$

A=8.6 feet

** Thing to note is that you can rearrage the sine formula to have either the legnth or the angle on top. It's pretty straightforward, find the angles you do have and then work from there. If sine law doesnt work with your example, use cosine law. and work backwards. Wish you luck.
