Answer:
Because square root is essentially the same thing as the power to a half
sqrt(x) is the same as (x)^1/2
Answer:
Infinite solutions
Step-by-step explanation:
Equation M is equation P multiplied by 3. The equations are dependent, so any solution of one of them is also a solution of the other. There are an infinite number of (x, y) pairs that will satisfy either (both) equation(s).
Answer:
Distance to the xy-plane = |z|
Distance to the yz-plane = |x|
Distance to the xz-plane = |y|
Step-by-step explanation:
The distance from P(x,y,z) to the xy-plane is by definition the magnitude of the vector that goes from the perpendicular projection of P over the xy-plane to the point P, which is exactly the magnitude of the vector (0,0,z) = |z| the absolute value of z
Similarly, the distance from P to the yz-plane is |x| and the distance from P to the xz-plane is |y|
Distance to the xy-plane = |z|
Distance to the yz-plane = |x|
Distance to the xz-plane = |y|
