A NASA mathematician used a system of equations to determine the point in space where a satellite crossed paths with a massive p
iece of space debris. How many equations did he need? And how many variables were needed to find the exact location in space? A) 3 equations with 2 variables
The coordinates of a point in space must necessarily have 3 components. One to describe the distance on the x axis, another to describe the distance on the y axis to the point, and a third to describe the distance on the z axis.
If we have three variables, then 3 equations are needed to solve the system. With less than 3 equations it would be impossible to solver the system.
The amplitude is usually the first number (for example, in this equation, the 3). Then you also know that the right or left shift depends on the addition or subtraction sign. Usually, the subtraction sign means to the right and the addition sign means to the left.
