Answer:
Answer C is correct
<em>Step-by-step explanation:</em>
<em>1. We replace x as (a + 2)</em>
<em>2. Then we just rewrite this function with the new value</em>
<em>3. Result: 3(a+2) + 5/(a+2)</em>
54/x = 6...multiply both sides by x
54 = 6x...divide both sides by 6
54/6 = x
9 = x
Slope=(y2-y1)/(x2-x1)
=(5-4)/(4-2)
=1/2
slope > 0 => the line rises (from left to right).
Answer: If the radius is 23 then the answer is 1661.9 (WHEN ROUNDED & WITHOUT). If the radius is 11.5 the answer is 415.5 (WHEN ROUNDED)
Step-by-step explanation:
The formula for the area of a circle is: radius x radius x pi/3.14
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
.
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) =
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)
