Answer:

(4,3), (4,-3), (-4,-3)

Step-by-step explanation:

Point E' is reflected over the x axis. so the X coordinate will stay the same. But the Y coordinate will turn into a negative.  So, (4,-3)

When E' is reflected over the Y Axis to make E'', the X coordinate changes but the Y coordinate stays the same.  So, (-4,-3)

Electrical poles that carry elecrtical wire seem to get smaller the farther away they are. Find the apparent height of each pole
lisabon 2012 [21]

Answer:

The answer to the question is;

Then the apparent height of each pole if the tallest pole is 50 feet tall and there is 100 feet between each pole is \frac{50*x}{(x + 100*n)} .

Step-by-step explanation:

To answer the question we have

Let the location of the closest pole = x

Let the height of the closest pole = h feet

Also let the actual  height of the pole at location 100×n feet away be 50 feet

Where n = 1, 2, 3, ...∞

Then we have by taking tangent of the similar triangles so formed by the poles

Then h/x = 50/(x +100·n)

Therefore h = 50 × x/(x +100·n) = 50·x ÷(x + 100·n) = 50 \frac{x}{(x + 100n)} feet

The apparent height of each pole if the tallest pole is 50 feet tall and there is 100 feet between each pole is 50·x /(x+100·n) where n is the number of 100 feet further away the pole is e.g when n = 1 we have

h = 50·x /(x+100·1)  = 50·x /(x+100)
