The numerical representation and final elevation of the fish relative to sea level are :
- Final position = -13.52 + 7.8
- Final position = - 5.72
<u>Given the Parameters</u> :
Initial depth of fish = - 13.52
Change in elevation of fish = 7.8 feets
Positions below sea level are represented as negative values (-) ;
Hence, initial position of fish = - 13.52
Change in position = Rise in depth of 7.8 feets
<u>The numerical representation of the final position of the </u><u>fish</u><u> </u><u>can</u><u> </u><u>be</u><u> written thus</u> :
- Final position = Initial position + change in position
- Final position = - 13.52 + 7.8
Hence, the final position of the fish will be :
- Final position of fish = -13.52 + 7.8 = - 5.72

Answer:
A coordinate system,or Coordinate plain ,is used to locate points in a 2-dimensional plane.
explanation:
A coordinate plain is formed by the intersection of two lines.One line is vertical and the other is horizontal.The vertical line is called y- axis and the horizontal line is called x-axis. It is two dimensional plane,which means it has length and breadth but no depth.The point where both the lines intersect is called the point of origin.Any point can be located on the coordinate plain by numbers(x,y). These pair of numbers are called coordinates.
It is used to plot points and lines.This system explains algebraic concepts .it has four equal divisions called quadrants namely I ,II,III,IV.
Answer:
A - B = [ -1 3 ]
[ -6 2 ]
[ -4 -10 ]
Step-by-step explanation:
Since Matrix A and Matrix B have the same size, then we can simply perform the operation of subtraction on each position within the matrices to get the resulting subtracted matrix.
A = [ 4 7 ] B = [ 5 4 ]
[ -3 8 ] [ 3 6 ]
[ -5 -2 ] [ -1 8 ]
A - B = [ (4 - 5) (7 - 4) ]
[ (-3 - 3) (8 - 6) ]
[ (-5 - -1) (-2 - 8) ]
A - B = [ -1 3 ]
[ -6 2 ]
[ -4 -10 ]
Cheers.
