Question

The height h (in feet) above ground of a seat on a Ferris wheel at time t (in minutes) can be modeled by... Screenshot below. Please help! Thank you!)

Answer 1

Screenshot of the problem! Sorry for asking for help! But please help me! Thank you!

Answer 2

you don't need to be sorry to ask for help. It is very good that you are asking. we are here to help you to learn the material so you can be more confident and can work independently and accurately.

Answer 3

Thank you!! Can you help me get started on the problem?

Answer 4

I spent the time reading so I will know how to approach and guide you. apparently you only need an answer and I don't want to be rushed

Answer 5

Thank you! I will be waiting patiently. I am sorry if I seemed impatient.

Answer 6

you will need to find H(0) and h(1) for 24 sec

Answer 7

@mathmale do you want to take this? too upset to work right now

Answer 8

What is wrong?

Answer 9

@zepdrix can you please take this?

Answer 10

So for h(t) I substitute 24 sec?

Answer 11

did you get 6.1 for H(0)?
no at 24 sec t= 1 H(1) means the height after 1 revolution

Answer 12

@3mar do you want to help here?

Answer 13

Did I offend you in any way? And for the H(0) the the equation is number+number*n?

Answer 16

Well, I am here.
Could you give me just 2 min?

Answer 17

Yes!

Answer 18

h=53
when
\[\sin \left( \frac{ \pi }{ 12 }t-\frac{ \pi }{ 2 } \right)=0\]
or
\[\frac{ \pi }{ 12 }t-\frac{ \pi }{ 2 }=n \pi\]
\[\frac{ \pi }{ 12 }t=n \pi+\frac{ \pi }{ 2 },t=\frac{ 12 }{ \pi }\left( n \pi+\frac{ \pi }{ 2 } \right)=6(2n+1)\]
t=6,18 (when n=0,1)

Answer 19

So for the three solutions .0306, .4233, .816? What blank does that go with?

Answer 20

these are the options?

Answer 21

Aren't those the solutions for t~.0306+.3927n? And then you plug in n for 0,1, and 2?

Answer 22

Yes I got 6 and 18 for the first blank! Thank you!

Answer 23

it will be be at highest point when \[\sin \left( \frac{ \pi }{ 12 }t-\frac{ \pi }{ 2 } \right)=1=\sin \frac{ \pi }{ 2 },\frac{ \pi }{ 12 }t=\frac{ \pi }{ 2 } +\frac{ \pi }{ 2 }\]
t=12

Answer 24

Thank you!!! You are saving my life right now!

Answer 25

\[\sin \left( \frac{ \pi }{ 12 }t-\frac{ \pi }{ 2 } \right)=1=\sin \left( 2n \pi+\frac{ \pi }{ 2 } \right)\]
find t upto 120 by putting n=0,1,2,...

Answer 26

sorry i am leaving now,i have to go.

Answer 27

How do I do the very last problem though?

Answer 28

I am watching
By the way he deserves a medal!

Answer 29

How do I give a medal?

Answer 30

Do I press best response? I am new to this website

Answer 31

Yes, you are right!

You did it!
Congratulations! ♥

Answer 32

Thank you! And is the the last answer is it 12,44,76,108? @3mar

for t??

Answer 34

12,36,60,84,108 wait its this. But the next to last one I still can't get

Answer 35

The only one I can't seem to get is "If the ride lasts 120 seconds, then how many times will a person be at the top of the ride?" @3mar

Answer 36

Wait its 5! Thank you!!! And goodnight @3mar

Answer 37

Good Night!
