Answer:

3.9 units

Step-by-step explanation:

We are given that,

Time taken by each swing = 2.2 seconds

The pendulum formula is given by, T = 2\pi \sqrt{\frac{L}{32}}, where T is the time taken and L is the length of the swing.

So, we have,

2.2= 2\pi \sqrt{\frac{L}{32}}

i.e. \frac{2.2}{2\pi}=\sqrt{\frac{L}{32}}

i.e. (\frac{2.2}{2\pi})^{2}=\frac{L}{32}

i.e. L=32\times (\frac{2.2}{2\pi})^{2}

i.e. L=32\times \frac{4.84}{4 \pi^2}

i.e. L=32\times \frac{1.21}{\pi^2}

i.e. L=\frac{38.72}{9.87}

i.e. L = 3.923 units

So, rounded to tenths, the length of the swing is 3.9 units.

15>0.6 (10+n)= that is the full problem
Lemur [1.5K]
N<−1.6 repeating is the answer

the work

Let's solve your inequality step-by-step.
5>0.6(10+n)
Step 1: Simplify both sides of the inequality.
5>0.6n+6
Step 2: Flip the equation.
0.6n+6<5
Step 3: Subtract 6 from both sides.
0.6n+6−6<5−6
0.6n<−1
Step 4: Divide both sides by 0.6.
0.6n
