Start by finding the average rate of change on [60, 90] and [90, 120]. Use the formula that you have written down already. <@&268886789983436800>

Oh no

Im so sorry for that

#

Thats my work for b

#

I know it's right

#

But the sentences get to me

#

And also knowing the units

#

Like idk what to put in for units

sage geode May 7, 2025, 10:12 PM

#

fast wolf I know it's right

It isn't right though

fast wolf May 7, 2025, 10:12 PM

#

It says equals to zero tho?

sage geode May 7, 2025, 10:13 PM

#

You swapped the t and f(t) values

fast wolf May 7, 2025, 10:13 PM

#

I thought it was

sage geode May 7, 2025, 10:13 PM

#

Yet you got 60/0

fast wolf May 7, 2025, 10:13 PM

#

Yeah

#

wait

#

Oh man

#

Welp

#

Idk

fast wolf May 7, 2025, 10:15 PM

#

sage geode Start by finding the average rate of change on `[60, 90]` and `[90, 120]`. Use t...

I got that

sage geode May 7, 2025, 10:15 PM

#

$$\frac{0.1 - 0.1}{120 - 60}$$

fast wolf May 7, 2025, 10:15 PM

#

sage geode May 7, 2025, 10:15 PM

#

This is what the fraction should have been

@sage geode

sage geode May 7, 2025, 10:16 PM

#

Anyways, have you heard of the Mean Value Theorem?

fast wolf May 7, 2025, 10:17 PM

#

Yeah

#

Looking at the graph right?

sage geode May 7, 2025, 10:17 PM

#

fast wolf Yeah

Do you know how to apply it here?

fast wolf May 7, 2025, 10:17 PM

#

sand mountain <@751533372890677398>

I had ir backwards 😭

sage geode May 7, 2025, 10:17 PM

#

fast wolf Looking at the graph right?

What graph are you looking at?

fast wolf May 7, 2025, 10:17 PM

#

I meant table

#

sage geode May 7, 2025, 10:18 PM

#

Once you find that the average rate of change of f(t) on [60, 120] is 0, you shouldn't need to look at the table anymore.

fast wolf May 7, 2025, 10:27 PM

#

Ahh okay

#

So like what now

#

After?

sage geode May 7, 2025, 10:31 PM

#

fast wolf So like what now

Do you know how to apply the Mean Value Theorem?

fast wolf May 7, 2025, 10:31 PM

#

Not really

#

I have issues with ivt and mvt

sage geode May 7, 2025, 10:36 PM

#

#

We already found the second part of c: f'(c) = 0

#

Are the two requirements satisfied? @fast wolf

fast wolf May 7, 2025, 10:37 PM

#

Yeah yeah

sage geode May 7, 2025, 10:40 PM

#

fast wolf Yeah yeah

Then you can use the Mean Value Theorem

#

Do you understand?

fast wolf May 7, 2025, 10:40 PM

#

There is a time f prime of cargo = 0 by mvt?

#

Like that?

#

Could you check c as well

sage geode May 7, 2025, 10:43 PM

#

fast wolf There is a time f prime of cargo = 0 by mvt?

You must specify that a < c < b

#

Also, you don't have to interpret the answer because they're only asking about f(t) rather than gallons per second. If you choose to do so anyway, you risk losing points for not interpreting the question correctly.

sage geode May 7, 2025, 10:44 PM

#

fast wolf Could you check c as well

Whats the original question for C?

fast wolf May 7, 2025, 10:45 PM

#

sage geode Also, you don't _have_ to interpret the answer because they're only asking about...

Ahh okay got it 👍

#

sage geode May 7, 2025, 10:48 PM

#

fast wolf Could you check c as well

fast wolf May 7, 2025, 10:48 PM

#

Oops

#

I meant to put as an x

#

Immeant t

#

#

Can u check d

#

Np no

#

Bad bad mathb

#

Ignore that

#

Also how do you know what units im using man

#

Bc j realy get confused

#

What units do I use after solving

#

#

Okay o soled it

#

Now I need to do this

#

What doesn't mean by changes?

sage geode May 7, 2025, 11:23 PM

#

fast wolf What doesn't mean by changes?

It means where v(t) changes signs
