Answer:
A. Building A, it is around 100.69 feet taller than building B.
Step-by-step explanation:
Since building A is 120 feet away at and elevation of 
, then:
Tan = 
Where x is the height of the building at the horizontal plane.
x = Tan × 120
= 100.692 feet
For building B at the same elevation,
Tan = 
x = Tan × 60
= 50.346 feet
Since the angle of elevation are the same, building A is around 100.69 feet taller than building B.
15 times .25 or 1/4
(1lbs=4 kids, 15 divided by 4= 3.75)
6.25 divided by .5 is over 12
so 12 adults
You would multiply by the reciprocal (flip the fraction)
5/3 * 24 = 40
b = 40
Problem 1
With limits, you are looking to see what happens when x gets closer to some value. For example, as x gets closer to x = 2 (from the left and right side), then y is getting closer and closer to y = 1/2. Therefore the limiting value is 1/2
Another example: as x gets closer to x = 4 from the right hand side, the y value gets closer to y = 4. This y value is different if you approach x = 0 from the left side (y would approach y = 1/2)
Use examples like this and you'll get the results you see in "figure 1"
For any function values, you'll look for actual points on the graph. A point does not exist if there is an open circle. There is an open circle at x = 2 for instance, so that's why f(2) = UND. On the other hand, f(0) is defined and it is equal to 4 as the point (0,4) is on the function curve.

Problem 2
This is basically an extension of problem 1. The same idea applies. See "figure 2" (in the attached images) for the answers.
