the weight of an object follows this equation: , where C is a constant, and r is the distance that the object is from the center of the earth.
a. Solve the equation for r.
b. Suppose that an object is 100 pounds when it is at sea level. Find the value of C that makes the equation true. (Sea level is 3,963 miles from the center of the earth.)
c. Use the value of C you found in the previous question to determine how much the object would weigh in
i. Death Valley (282 feet below sea level)
ii. The top of Mt McKinley (20,430 feet above sea level)

w=C/r --> r=w/C
C = 100* 3963 = 396300
w = 396300/(3963-282)= 100.0013 pounds
w = 396300/(3963+20430/5280) = 99.9 pounds

What shapes do you get once you chop up the sq. with a diagonal? 2 trangles. provided that all of us understand the sphere is a sq., which skill all of the facets are equivalent (hence, in case you realize one section, you realize all of the facets). So now you have a trangle with 2 facets equivalent to 60 feet. you may now use Pythagorean's theorem: A (squared) + B(squared) = C (squared) A and B are your 2 facets after which you merely remedy for C. stable good fortune!
