i found this thing in the sand at the beach during low tide in carlsbad. the sand was very wet. it was shaped like an oval wiht an indentation at the top. and it kinda looked like the cross section of an apple. at the indentation was this wormy projection about 4 cm long. the whole thing was pretty much flat and 8 cm in diameter. it had a soft body with bumps on the top and ridges radiating out from the central point on the underside. the underside looked like that of a mushroom. the top was gray and the bottom was purple. what is it? is it even alive?

How would I enter this data to get the correct answer:

The problem has to do with elasticity, but it could also be a problem to find the slope.

20,002 - 20000/20000 / 99.5-100/100 = 61.67

Please, as you answer the question; Please do it step by step.

Like first enter....

Then enter.....

I do this too many times and every time I get a different answer, and next week is test day....HELP!

I've learned the chain rule in calculus today, but my teacher never explained how to use it with an absolute value function. I think I get the general idea...but could someone check?

Problem: Let f be a real-valued function defined by f(x) = sin^3x + sin^3 x abs(x).

Now: Find f ' (x) for x >0 and f ' (x) for x < 0.

Is it like this when you derive it...?

f ' (x) = 3 sin^2 x + 3 sin^2 x abs(x) x 1

But how does the absolute value work out with the 2 questions...? Please help!

for this car it will come off a ramp and will have to travel 3 meters and stop on a mark (where a dime is placed).
i have to design this car! It can't have any source of power, except the momentum gained from the ramp. It could have some form of breaking system!

LOOKING FOR SUGGESTIONS

you are not allowed to have a strong breking system like from a rc car!
