Answer:

c = 17
Step-by-step explanation:
This is the Pythagorean theorem
Multiply the amount per dollar offered by a bank, by the number of dollars you want to exchange it all depends on exchange rate they have it at.
We can find the acceleration via

We have


Then by definition of average acceleration,

so that


We alternatively could have found the time without knowing the acceleration. Since acceleration is constant, the average velocity is

Then


Answer:

Step-by-step explanation:
The rates are additive: you can calculate the<em> inlet </em>rate and the <em>outlet</em> rate and add them algebraically, i.e. the inlet rate will be positive and the outlet rate will be negative.
<u>1. Inlet rate:</u>

<u />
<u>2. Outlet rate:</u>

<u>3. Net rate:</u>

<u>4. Time to fill the vat</u>


Answer:
like here x= 3 and y= -15
here, its 5 times goes in negative
now if y = 10 TO X IS 5 TIME POSITIVE HERE = 10×5 = 50
