Question
Determine the
units of the variable x in each of the
following equations, and specify which
rule you used to determine this. Do not
solve for the numeric value of x. Show
your work beneath the question, or on a
separate sheet of paper.
Example: 315 feet = (32)x²
Rule #1: Both sides of the equal sign must have the same units.
Rule #2: Values that are added or subtracted must have the same units.
Rule #13: Argument of a trig function must be an angle.
Rule #14: Argument of an inverse trig function must have no units.
Rule #5: Exponents must have no units.
x has units of seconds
