Sabendo que a aceleração da gravidade na Terra é igual a 9,8 m/s² e que na Lua o valor dessa aceleração é de aproximadamente 1,6 m/s², determine qual seria o peso de uma pessoa de massa igual a 80 kg tanto na Terra quanto na Lua.

Which is a true statement comparing the graphs of x^2/6^2-y^2/8^2 = 1 and x^2/8^2-y^2/6^2 the foci of both graphs are the same points. the lengths of both transverse axes are the same. the directrices of = 1 are horizontal while the directrices of = 1 are vertical. the vertices of = 1 are on the y-axis while the vertices of = 1 are on the x-axis.
