Question

Screenshot of problem! Please help me! I need this desperately.

Answer 1

Any ideas?

Answer 2

Well not really.

Answer 3

Please someone help though because it is due by 12:00!

Answer 4

Can you type in the governing equation here?

Answer 5

Can you just please show me the steps and I will try to understand it? It is just due by 12! And I am getting really scared that I won't have enough time!

Answer 6

No, sister!
Don't worry!

If you just substitute with the givings \(r\) and \(V_0\) in the equation, you will get \(sin(2\theta)\)

Can you?

Answer 7

Still need help?

Answer 8

1/32 (100)^2 sin2(feta) =300

Answer 9

Then after this step I do not know where to go honestly

Answer 10

This problem makes me want to slam my head into the wall repeatedly

Answer 11

No No

Answer 12

1/32 (100)^2 sin2(feta) =300

Congratulations! ♥


Can you now separate \(sin(2\theta)\) in one side?

Answer 13

1/32 (120)^2 sin2(feta) =300 Wait correction it's

Answer 14

I am not sure how to separate it. Is it an identity?

Answer 15

Just like this:

\[\Large 300=\frac{ 1 }{ 32 }(120)^2*\sin (2\theta)\]
\[\Large 300*32=\frac{ 1 }{ 32 }*32*(120)^2*\sin (2\theta)\]
\[\Large 9600=14400*\sin (2\theta)\]
\[\Large \frac{ 9600 }{ 14400 }=\frac{ 14400*\sin (2\theta) }{ 14400 }\]
\[\Large \frac{ 2}{ 3}=\sin (2\theta)\]
\[\Huge 2\theta=\sin^{-1}(\frac{ 2 }{ 3 })\]
\[\Huge 2 \theta=~??\]

Answer 16

@Please.help.me
Are you there?

Answer 17

.272972?

Answer 18

Or 41.8103 ?

Answer 19

\[\Huge \sin^{-1}(\frac{ 2 }{ 3 })=~?~?\]

Answer 20

0.72973

Answer 21

?

Answer 22

It would be 41.81 degree.

Can you do it or not?

Answer 23

Need help to calculate so?

Answer 24

Let me know where you are back!

Answer 25

They want degrees (notice the small º to the right of the "entry box")

so
2\(\theta\) = 41.81º

However, notice you must divide by 2 to get theta

Answer 26

feta = Greek cheese
theta = \(\theta\) = Greek letter

Answer 27

I divided the answer by two but it was still marked wrong.
