Lets review the options one by one:
X A.) The question says the y must be <u>less than</u> 100, not less than or equal to.
X B.) The y becomes 0, but 0 is neutral, not a positive number.
X C.) The height must be positive at all times, according to the range given.
√ D.) The given graph contains a max with a positive number under 100.
Therefore, the correct answer choice would be Option D (4).

Answer:
4.9 feet
Step-by-step explanation:
First, we need to determine the height of the building using the following:

Where
H = Height of the building
L = Length of the first ladder = 20ft
B = Distance from the base of the building = 10ft
So, we have:





Next, is to determine the distance of the new ladder from the base of the building (B) using Pythagoras theorem using:

Where
--- Length of the second ladder
----- Height of the building
So, we have:




Solving for B2, we have:


Answer:
five minus y
Step-by-step explanation:
BD=10 because it is symmetrical to AD.
The answer to this is a conversion of 1 meter to feet which is about 3.3 ft
