The weight (in pounds) w=f(d) of an object varies inversely as the square of its distance (in thousands of miles) d from the cen
yuradex [85]
The joint variation that is given in the problem above can be expressed as follows:
                                    w = k/d²
where w is the weight, k is the variation constant, and d is the distance from the center of the earth. Substituting the first scenario to obtain the value of k,
                                     160 = k/(4000)²
                                        k = 2.56 x 10^9
Using this value for the second scenario,
                                       w = (2.56 x 10^9) / (8,000)² = 40 lbs
Thus, the weight of the man, 8000 miles above the center of the earth is 40 lbs.

Answer:

  see attached

Step-by-step explanation:

It is helpful to understand that the product of the binomial factors is ...

  (ax +b)(cx +d) = ac·x² +(ad+bc)x +bd

For these problems you only need to look at the constant and the leading coefficient to find the missing values.

__

1. d = 8/-4 = -2

2. b = -24/(3·2·d) = -4; c = 3/(3·a) = 1

3. a = 2/c = 1; d = -24/b = 6
