A 6.0g of methane decomposes into 4.5g of Carbon and 1.5g of Heydrogen. Determine the empirical formula of methane.

Let f(x)=4−x^2. Find each of the following: (f(2+h)- f(2))/h = ________ lim h->0 (f(2+h)- f(2))/h = ______

Use algebra to evaluate the limit lim h->0((2−h)^2−8)/h

The position of a particle moving along the x-axis is given by s(t)=2t2+4. Use difference quotients to find the velocity v(t) and acceleration a(t), filling in the following expressions as you do so: v(t)=limh->0 [_____ / h ] = ____ a(t)=limh->0 [ ____ /...

A continuous function f, defined for all x, has the following properties: 1. f is increasing 2. f is concave down 3. f(13)=3 4. f'(13)=1/4 Sketch a possible graph for f, and use it to answer the following questions about f. A. For each of the following in...

Find the dereivative of: y =((x^2+1)/2)^6 I really don't know the process to do these one, I tryed to use the quotient rule but then I don't know how to do with the ^6 so I don't think that's the way to do it...

Fill in the following table, where E(x) denotes the error in approximation of f(x) by T(x). x - 2 x 3 2.1 2.01, 2.001 f(x) T(x) E(x)

Let f(x) = x^3 - x^2 + x - 1. Find an equation for tangent line to f at x = 2.

A projectile of mass m is launched from the ground at time t = 0, with speed v0, at angle theta0 above the horizontal. Aerodynamic drag is negligible. Write the kinetic, potential, and total energies of the projectile as explicit functions of time.

A car experiences rolling (tractive) friction with coecient of friction mut = 0.0200, and turbulent-flow (bv^2) drag, with drag coefficient CD = 0.300. The car has mass (including fuel, which is a negligible fraction of the total) M = 1000. kg and fronta...

In solid sodium chloride (table salt), chloride ions have one more electron than they have protons, and sodium ions have one more proton than they have electrons. These ions are separated at about 0.28 nm. Calculate the electrostatic force between the sod...

Write the standard form to identify the value of a, b and c. 1.) 6x(4x+3=4

I tried and I got -1.17 for one of them... I plugged both answers and I just got the g(2) right, I'm not sure what to do now....

I'm sorry, yeah it's ((2-h)^3 - 8)/h

Oh ok... thanks a lot, I was typing 12 all this time....

I don't understand very well what I have to do...What I did before was v= P/W P= (mu(mg)+(1/2)(CD)(rho)Sv^3) w=36.0 MJ*20% V=((mu(mg)+(1/2)(CD)(rho)Sv^3)/ (36x10^6 *0.2) I plugged in the values and got .00217 L/s and then to get the gas mileage=(0.00218^-...
