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)

The product of 4 and the sum of a number x and 8
Nesterboy [21]

Answer:

8(x+3)

Explanation:

"The product of 8 and" means 8 is going to be multiplied times another quantity. "...the sum of a number x and 3" means that 8 is going to be multiplied times (x+3).

This is represented by 8×(x+3), which simplifies to 8(x+3).

Find the distance between the two points given
Hunter-Best [27]

Answer:

6√2

Step-by-step explanation:

from the graph the coordinates of the points are (2, 5) and (- 4, -1)

the distance is d= √(x2-x1)²+(y2-y1)² = √(-4-2)²+(-1-5)²=√72 = √2*2*2*3*3= 6√2
