Answer:
255 m
Step-by-step explanation:
From the given question, the surface of the water body is the reference point. And this point is assumed to be 0, so that any distance above it is positive, and any distance below is negative. This is synonymous to the number line system.
Thus,
For the aircraft, its height = +200 m
For the submarine, its depth = -55 m
So that the difference between the submarine and aircraft can be determined as;
200 - (-55)
= 200 + 55
= 255 m
The distance between the submarine and aircraft is 255 m.
Answer:
Step-by-step explanation:
Since we have been given height of triangle as 8 and length of its base as 3. We can use similar triangles to express the base of the smaller triangle in terms of h.
The height of the smaller triangle will be
Let x be the base of the smaller triangle. Therefore, using similar triangles, we can set the ratios of corresponding sides of the two triangles equal to each other as shown below:
Now, we can express the area of the small rectangular strip of length x and thickness Dh as shown below:
Therefore, the required Riemann sum can be expressed as:
The required areas can be expressed as:
