84 pounds on earth is about 14 pounds on the moon but to be exact it is 13.89 pounds.
/ means divide, so U( an unknown value ) / 6 = 9. to get the answer, simply multiply 6 x 9
f(x) is a multiple of the cosine function. g(x) is a multiple of the sine function. Both the cosine function and the sine function have a maximum value of 1, so the magnitude of the multiple will determine which function has the largest maximum value.
The multiple for f is 2; the multiple for g is 3, which is greater than 2. Hence g(x) has a larger maximum value than f(x).
