Time is precious, but we do not know yet how precious it really is. We will only know when we are no longer able to take advantage of itâ€¦iii)z varies directly as the square of x and inversely with the square root of y.. So22ykxzyxzï€½ïƒžï‚µExample 1The law of universal gravitation states that the gravitational force F (in newtons)between two objects varies jointly with their masses m1and m2(in kilograms) and inverselywith the square of the distance d (in meters)between the two objects. The constant ofvariation is denoted by G and is called theuniversal gravitational constant. Write anequation for the law of universal gravitationhence estimate the universal gravitationalconstant. Use the Earth and sun facts givenat the rightï‚´
4)Write an equation for the given relationship.a)x varies inversely with y and directly with z.b)y varies jointly with z and the square root of x.c)w varies inversely with x and jointly with y and z.5)The variable z varies jointly with x and y. Use the given values to write an equation relatingx, y, and z. Then find z when x =-4 and y = 7.(a) X=3, y=8. Z=6(b) X=-12, y=4, z=2(c)? ==
Exercise1)Tell whether x and y show direct variation, inverse variation, or neither?(e)d)xy1.640416512.8203.2
