Answer:
0
Step-by-step explanation:
Given
Required
Determine its new position
Because the ring was initially below the surface of the pool;
Its initial position is
Taking it to the surface of the pool;
It means, the ring travels a distance of:
It's final position is the summation of its initial position and distance travelled;
<em>Hence, 0 represents its new position with respect to the surface of the water</em>
Slope of parallel line: -7/6
Slope of perpendicular line: 6/7
7x + 6y = 5
6y = -7x + 5
y= -7/6x + 5/6
