f(x)= xsquared -2x for y= absolute value of f(x) does the derivitive exist at x=0 and explain why.

first convert 600km/h to m/s then use the equation final velocity suqared = initial velocity squared plus 2 times aceleration times distance. remember initial is 0m/s. Then once you find acceleration use the equation final velocity equals initial velocity plus acceleration tim...

A leaky faucet fills a 100 millimeter cup in 10 minutes. 1.how much water is wasted in a day?a week?a non leap year? 2.How long does it take to waste a kiloliter of water? (hint:1 kiloliter=1000000 milliliters)

wow didnt think of it that way. thanks a lot =)

in a lab experiment to obtain the molar mass of a voltaile liquid, the following data is obtained: volume of flask=225ml mass of flask=77.834gms mass of flask+gas=78.416gms temperature=100 degrees celsius pressure=714 torr What is the molar mass of the liquid? A)11.1 g/mol B)2...

Is anyone here a chemistry genuis?
The formate ion, (CHO2-), is related to the acetate ion and forms ionic salts with many metal ions. Assume that 9.7416 g of M(CHO2)2 (where M represents the atomic symbol for a particular metal) are dissolved in water. When a solution of 0.200 M sodium sulfate is added, a whit...

physics
knowns: F=20N h=15m V=25m/s unknowns: max h V1 work-energy theorem: W=K2-K1 K=.5*mV^2 so, m(-g)h=.5mV2^2-.5mV1^2 this simplifies to 2(-g)h=V2^2-V1^2 therefore, V1=sqrt(V2^2+2gh) now all you have to do is plug in numbers. V1=sqrt(25^2+2*9.8*15)=30.32m/s max height is where V=0 ...
