Answer: Approximately 22.62 degrees
===============================================
Work Shown:
cos(angle) = adjacent/hypotenuse
cos(y) = 12/13
y = arccos(12/13)
y = 22.6198649
y = 22.62
Notes:
- Arccosine is the same as inverse cosine. On your calculator there should be a button labeled
- Make sure your calculator is in degree mode
- The decimal result for y, shown above, is approximate. I rounded to two decimal places to show the final answer. Round however you need to if your teacher instructs otherwise.
Answer:
127.53 liters left after 10 minutes
Step-by-step explanation:
Let
Given
--- initial
--- the amount left, after 5 minutes
Required
--- amount left after 5 minutes
To do this, we make use of:
implies that:
Divide both sides by 200
Take natural logarithm of both sides
So, we have:
Divide by 5
So, the function is:
The amount after 10 minutes is:
Answer:
