Answer:
<em>The length of the arc on the sixth swing was </em><em>12.18 ft.</em>
Step-by-step explanation:
A rope is swinging in such a way that the length of the arc traced by a knot at its bottom end is decreasing geometrically.
The third arc is 22 ft. long and the seventh arc is 10 ft.
Hence, the 3rd term is 22 and 7th term is 10.
The length of the arc on the sixth swing is asked, so we have to calculate the 6th term.
We know the nth term in GP is,
So,
----------------1
----------------2
Dividing equation 2 by 1,
Then the 6th term will be,
----------------3
Dividing equation 2 by 3,
Therefore, the length of the arc on the sixth swing was 12.18 ft.
Answer: 49 and 38
Step-by-step explanation:
I did trial and error
38+11=49
49+38=87

Answer/Step-by-step explanation:
Apply trigonometric bratio formula where applicable, to find the value of x in each case. Recall the acronym, SOHCAHTOA. This will help toe ash determine which ratio formula to use depending on the information given.
4.
Opp = x
Hyp = 14
Therefore, apply SOH. Which is,
Multiply both sides by 14
(nearest tenth)
5.
Adj = x
Hyp = 14
Therefore, apply CAH. Which is,
Multiply both sides by 14
(nearest tenth)
6.
Opp = x
Adj = 5.4
Therefore, apply TOA. Which is,
Multiply both sides by 5.4
(nearest tenth)
7.
Opp = x
Adj = 33
Therefore, apply TOA. Which is,
Multiply both sides by 33
(nearest tenth)
