Weight. The weight Fof a body varies inversely with the square of the distance between the body and the center of the Earth. If a man weighs 100 pounds 4,000 miles from the center of the Earth, how much will he weigh at a
distance of 5,000 miles from the center of the Earth
He will weigh
lbs.

the graph in the attached figure

step-by-step explanation:

we have

using a graphing tool

the graph in the attached figure

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
