Yep, Alan......the adventures of "Tod" and "Buz" ...I used to think that Corvette they traveled around in was pretty cool......(gawd....I'm dating myself  !! )

P.S.  ....funny trivia......"Tod" and "Buz" rarely EVER traveled on "Route 66" during the show......!!!

Well....at least I don't have any memories of "The Great Depression"   ...!!!

Can we all agree???.........this problem might be "over-worked," at his point.......

I'm going to "white out" any further posts on this because.....I HAVE THE POWER !!!

And I'm not afraid to use it, either.........

Your Humble Servant,

Interesting, reinout !!!

Convert 3+7/10 to an improper fraction = 37/10

Then....just divide the two numbers to get.....3.7

Aha...."Route" 666 ......!!!!  I knew you were "evil," reinout !!!

For the uninitiated, the image is a parody on "Route 66," a famous US highway used by many  who migrated to California looking for work during the 1930s Great Depression. The road is immortalized in John Steinbeck's classic work, "Grapes of Wrath."

P.S.  - There's nohing inherently "evil" about the number "666".......it's not any more or less "evil" than any other number......

Just divide both sides by  ... (v1 - v2)

So , we have ..... 1/√x =  x^(-1/2)

The antiderivative is just

F(x)  =  (2)x^(1/2) + C     or    2√x  + C

Prove this for yourself

F'(x) = x^(-1/2)  = 1/√x

Thanks for the further explanation....I was trying to see how you determined the radius and that made it clear !!!

I'm going to look at his one a little more......

I haven't seen that one before, heureka....but I like it !!!

I'll have to remember that technique !!

Thumbs Up and Points from me!!

OK...after 4 years, the computer loses $3000 of its original value

So...the slope of our equation repersents the change in value over the change in time, i.e.,

-3000/4    .....  so we have...an the original value is just expressed as (0, 3200) in terms of (t, v) this can be seen as the "y intercept" on the "t-v" axis  .... so we have

v = -(3000/4)t + 3200

Note that...the machine will become fully depreciated in the 5th year.......
