Determine the new position
It descends means that it moved in the downward position.
So, the new position is:



<em>Hence, the new position f the submarin is -415m</em>
Answer:
747
Step-by-step explanation:
let the 2 numbers be x and y with x > y, then
x - y = 275 ( the difference of the 2 numbers ) and
x - 236 = 275 ( the smaller number y = 236 )
Add 236 to both sides
x = 511
Thus x = 511 and y = 236, thus
x + y = 511 + 236 = 747
Just use the coefficients for each variable and put it in a matrix. Is the second question set equal to something? Because then you would put it in place as the question mark. (Did the pic come through?)
So the 3x3 matrix is made up of the coefficients and then to augment the matrix, you add another column at the end with the solutions. Good luck!

Answer:
<em> The distance from your eyes to the stage is 8.85 ft</em>
Step-by-step explanation:
Your distance to the stage is 6 feet
Your eyes are 6.5 feet tall
You need to find the distance of your eyes towards the stage.
This situation can be modeled using a rectangle triangle, where the adjacent side x is the horizontal distance to the stage and the opposite side h is the vertical distance of your eyes to the stage.
<u>Observe the attached image.</u>
Then, we look for the distance z from your eyes to the stage. This distance is the hypotenuse of the right triangle.
So, using the Pythagorean theorem we have:

Where

therefore:
