Answer: choice A) -4
-----------------------------------------------
Step 1) Draw a vertical line through 1 on the x axis
Step 2) Mark the point where the vertical line and the blue curve intersect (or cross each other)
Step 3) Draw a horizontal line through the point marked in step 2. Note how this horizontal line goes through -4 on the y axis.
So the point (1,-4) is on the blue curve. This means if x = 1 is the input then y = -4 is the output. Recall that y = f(x). So f(x) = -4 is the output as well when the input is x = 1.
In short, this is why f(1) = -4

Answer: The pole is 3.5 foot above the right hand.
To answer this question first you need to determine the left hand height/position. The left hand divides the pole segment into 2:1 ratio. If the pole if 15 foot long, then the equation will be:
2/(2+1)x 15 foot= 10 foot.
The left hand is located 10 foot from the ground and the right hand is 1.5 foot above it. Then the right hand position from the ground is:
10 foot+ 1.5 foot= 11.5 foot
Since the right hand is 11.5 foot from ground and the pole is 15 foot long, then the equation will be:
15 foot- 11.5 foot= 3.5 foot.
We know that
Population density<span> is a measurement of population per unit area
</span>[population density]=population/area-----><span>7,112,688/426.25----> 16686.66
16686.66----------> 16687 person/square mile
the answer is
</span>16687 person/square mile
