Answer:
<em> Length of guy wire is 590.6 ft</em>
Step-by-step explanation:
The complete question is
A radio transmission tower is 210 feet tall. How long should a guy wire be if it is to be attached 8 feet from the top and is to make an angle of 20° with the ground. Give your answer to the nearest tenth of a foot.
height of tower = 210 ft
8 ft fro the top leaves 210 - 8 = 202 ft to the ground
This is an angle of elevation problem
the opposite is 202 ft
hypotenuse = ?
angle is 20°
using sin ∅ = opp/hyp
sin 20° = 202/hyp
0.342 = 202/hyp
hyp = 202/0.342 = <em>590.6 ft this is the length of the guy wire</em>
Hi there!
In order to answer your question, you'll need to use the cross product method (let's say that Newtons = N):
9N on Earth = 2N on Namar
400N on Earth = xN on Namar
(2 × 400) ÷ 9 = xN on Namar
800 ÷ 9 = xN on Namar
88.888.. = xN on Namar
Since your answer must be to the nearest Newton, I'm guessing that you need to round your answer to the nearest whole number. This means that since the number in the tenths column is more than 5 (could also be equal to 5), you need to round the number up.
88.888... rounded to the nearest whole number = 89
Your answer is: The girl weigh 89 newtons on Namar.
There you go! I really hope this helped, if there's anything just let me know! :)
I don’t really know what it is but you can cross out A, B, and F for sure.
Answer:
x = 4.6439
Step-by-step explanation:
2^x =25
Take the log of each side
log 2^x = log 25
We know that log a^b = b log a
x log 2 = log 25
Divide each side by log 2
x = log 25 / log 2
x =4.643856
Rounding to 4 decimal places
x = 4.6439
