MHB Computation based on linear growth

AI Thread Summary
The company experienced linear growth in its customer base, increasing from 300 customers in 2000 to 1200 customers in 2015. To find the number of customers in 2008, the growth rate can be calculated based on the time frame and total increase. The correct number of customers in 2008 is indeed 780. The calculation involved is algebraic rather than calculus-based. Understanding linear growth is essential for accurate customer projections.

In 2000 the company had 300 customers. In 2015, this company already had
1200 customers. How many customers did the company have in 2008 if we know that
the number of customers growing is linear?Just want to make sure, is 780 the correct answer?

yes ... and this calculation is algebra, not calculus.
 

Thread 'Trigonometry problem of interest'

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...

Thread 'Six Pencil Puzzle'

Is it possible to arrange six pencils such that each one touches the other five? If so, how? This is an adaption of a Martin Gardner puzzle only I changed it from cigarettes to pencils and left out the clues because PF folks don’t need clues. From the book “My Best Mathematical and Logic Puzzles”. Dover, 1994.

Thread 'Imaginary Pythagoras'

Thread 'Imaginary Pythagoras'

I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
