mb = mass of bullet vb = velocity of bullet ma = mass of bag vab = velocity of bag and bullet from conservation of momentum: mb*vb = (ma + mb)*vab then from conservation of energy: (ma + mb)*vab^2/2 = (ma + mb)*g*h
A: it depends how the cube is painted. If the 3 blue sides of the original cube share a common corner then 7 of the smaller cubes have at least 2 sides that are blue. If 2 opposite faces of the original cube are blue then 6 of the 27 have at least 2 faces
books = (2ft x 12in/1ft)/(0.75in/book)
sa = 4 x pi x r^2 so r = sqrt( sa/(4 x pi))
2x^2-5x = x(2x-5) = 0 x = 0, 5/2
There is no answer. x would have to be less than zero which is beyond the bounds where the equation is valid.
If there are more than three authors you can use: Doe, Mary Jane, et al.
That is what I got also.
centripetal acceleration = a = v^2/L Period = T = 2 x pi x L / v m = mass of stone tension = f = m x a L1 = L x 1.01 if f and m are constant, then a is constant. Then v1 = sqrt(a x L1) T1 = 2 x pi x L1/v1 percentage change = 100x(T1-T)/T
zero
function of x equals x minus the absolute value of x, where x is greater than zero.
flooding, water pollution, and eutrophication can be a problem in either ocean or freshwater. Aquifer depletion, overdrawing surface water, and saltwater intrusion are freshwater problems.
the function is not continuous when the denominator is zero, or... 0 = x^2+1 solving for x then x = i It is a removable discontinuity since it can be repaired by replacing a single point.

0 = 4x^4-18x^2 = 4x^2(x^2-9/2) = 4x^2(x+sqrt(9/2))(x-sqrt(9/2))
v0 = 20m/s D = dist from int. = 110 - v0 x 0.50 t0 = time to stop final velocity must equal zero... 0 = v0 - a x t0 t0 = v0/a D = v0 x t0 - a x t0^2/2 substitute for t0... D = v0^2/a - a x (v0/a)^2/2 solve for a...

Profit = revenue - TC Revenue = [Price] x [tons of coal] Take the first derivative of profit with respect to Q and set this equal to zero, then solve for Q.
