I think best word to insert in the blank is the term "bisecting".
An altitude of a triangle is a line or segment that passes through a vertex of the triangle and is bisecting <span>to the line containing the opposite side.
</span>"Bisect<span>" means to divide into two equal parts which is true for the altitude of a triangle.</span>

Hello!</h2>
The answer is C. formulas
<h2>
Why?</h2>
Formulas are laws o conditions that help us when we are solving numerical problems, we use them to relate number/variables in order to found equivalence between what we are calculating and the information we have.
A formula can include constants, variables and always contain an equality, this last one will help us to establish the needed equivalence to solve numerical problems.
Discarding the other given options:
A. decimals: Incorrect, decimals are a type of number which is not whole numbers.
B. graphs: Incorrect, graphs are graphical tools that we can use to show information or data.
D. percentages: Incorrect, percentages are used to show numerical information as a fraction of 100 units.
E. fractions: Incorrect, like decimals, fractions are a type of number which is not whole numbers, fractions are represented by a division of a number into another, representing just a part of a determinate whole number.
Have a nice day!
Answer:
t =2 seconds
Step-by-step explanation:
We have, a function that represents the height y of the pebble after dropping the balcony as follows :
![y=80-16t^2](https://tex.z-dn.net/?f=y%3D80-16t%5E2)
The pebble lands on the top of a sign that is 16 feet high.
It is required to find the time does the pebble drop before hitting the sign. The above equation becomes,
![80-16t^2=16\\\\-16t^2+80=16\\\\-16t^2=64\\\\t^2=4\\\\t=2](https://tex.z-dn.net/?f=80-16t%5E2%3D16%5C%5C%5C%5C-16t%5E2%2B80%3D16%5C%5C%5C%5C-16t%5E2%3D64%5C%5C%5C%5Ct%5E2%3D4%5C%5C%5C%5Ct%3D2)
So, the pebble hits the sign after 2 seconds.
