problem 7

To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro's number: 6.02 x 10^23

problem 6

To solve the equation, you'll need to find the numbers for these values:

A = Total loan amount.

D = {[(1 + r)n] - 1} / [r(1 + r)n]

Periodic Interest Rate (r) = Annual rate (converted to decimal figure) divided by number of payment periods.

Number of Periodic Payments (n) = Payments per year multiplied by number of years.

problem 4

Bending moment is a function of the force x the distance. If the force is a point load it is simply the force x the distance [1] If the force is distributed or spread out you must integrate the forces and the distances [2]. Shear force is a function of the total force and the cross sectional area [2].

if the eqn of the parabola is f(x) = (x-4)(x+2), we need to mult. this out to find the coordinates of the vertex.

then f(x) = x^2 + 2x - 4x - 8, and f(x) = x^2 - 2x - 8.

one way in which you can find the vertex is to calculate x = -b / (2a).   here, that comes to

        )

x = = 1.   f(1) = 1^2 - 2(1) - 8 = - 9.   vertex is at (1, -9).

        2(1) 

find another point on the curve:   let x=0, for which y=-8.   then (0, -8) is on the curve.   plot the vertex and this point and draw a smooth parabola thru both.
