The function r(t)= 0.5 + t cos(πt³/80) is an illustration of a cosine function
The depth of water in the rain gauge increases by 1.466cm from t = 0 to t = 3
<h3>How to determine the increase in water depth?</h3>
The function is given as:
r(t)= 0.5 + t cos(πt³/80)
When t = 0, the depth of water is:
r(0)= 0.5 + 0 * cos(π *0³/80)
Evaluate
r(0) = 0.5
When t = 3, the depth of water is:
r(3)= 0.5 + 3 * cos(π *3³/80)
Evaluate
r(3)= 1.966
Calculate the difference (d) in the depths
d = r(3) - r(0)
So, we have:
d = 1.966 - 0.5
Evaluate
d = 1.466
Hence, the depth of water in the rain gauge increases by 1.466cm from t = 0 to t = 3

Explanation:
Ellos tuvieron un <u><em>accidente</em></u> de carro.
In this question we must fill the blank of a sentence in Spanish with a consistent and coherent choice, which is determined by common sense and own experience.

A word is considered effective/ineffective depending on whether the word transmits the author's message. In the case of Nancy, she wants to show students struggle as they deal with classes, homework, and extracurricular activities.
<h3>How to replace the word "have"?</h3>
The word "have" is ineffective because it does not completely show how difficult the situation is for students. One word that can show this struggle is "manage" because this emphasizes Nancy's point of view.
