5. A 17-foot ladder is leaned against a wall. If the
1 answer:
Answer:
15 feet
Step-by-step explanation:
Always draw out a diagram! Especially once you get to physics, its just best to be in the habit. There are a few ways we could solve this problem, but lets stick to the pythagorean theorem. a^2 + b^2 = c^2 .
so in this case, when we substitute its
a^2 + 8^2 = 17^2
a^2 + 64 = 289
a^2 = 225
a = 15
Therefore, the ladder reaches a height of 15 feet against the building.

Using the rational root theorem, it is found that your friend is correct.
<h3>What is the rational root theorem?</h3>- It is a theorem that states that for a polynomial with integer coefficients, with q being the factors of the leading coefficient and p being the factors of the constant, every <u>possible rational root</u> is the format
.
In this problem:
- The leading coefficient is 1, hence it's only factor is
, thus guaranteeing that every possible rational zero is an integer, which means that your friend is correct.
