Answer:

x ≈ 37.13°

Step-by-step explanation:

using the sine ratio in the right triangle

sin x = \frac{opposite}{hypotenuse} = \frac{13.4}{22.2} , then

x = sin^{-1} ( \frac{13.4}{22.2} ) ≈ 37.13° ( to the nearest hundredth )

What is the approximate length of a pendulum that takes 2.4 pi seconds to swing back and forth?
LuckyWell [14K]

Answer:

The length of the pendulum is 14.13 meters.

Step-by-step explanation:

The length of a pendulum is given by the formula, T = 2\pi \sqrt{\frac{L}{g} }, where T is the times period and L is the length of the pendulum.

Now, given that T = 2.4π seconds.

So, from the above equation, we get,

2.4\pi  = 2\pi  \sqrt{\frac{L}{g} }

⇒ \sqrt{\frac{L}{g}} = 1.2

⇒ \frac{L}{g} = 1.44 {We have the value of g as 9.81 m/sec²}

⇒ L = 1.44 × 9.81 = 14.13 meters. (Approx.)

Therefore, the length of the pendulum is 14.13 meters. (Answer)

<u>Answer:</u>

-x-3

<u>Step-by-step explanation:</u>

<em>They want you to simplify the expression.</em>

<u>Step 1:</u><em> Apply the distributive property.</em>

\frac{1}{5} (5x)+\frac{1}{5} (-15-2x)

<u>Step 2:</u> <em>Cancel the common factor of 5.</em>

x+\frac{1}{5} (-15-2x)

<u>Step 3:</u> <em>Cancel the common factor of 5.</em>

x-3-2x

<u>Step 4:</u> <em>Subtract 2x from x.</em>

-x-3
