Answer:

Step-by-step explanation:
The given function is

To find F(2), we substitute t=2 into the function.
This means that wherever we see t, we put 2

We multiply the exponent in the denominator to get:

We evaluate to get:

We now cancel the common factors to get:

Well what I would do is how much do I have to multiply by to get 150 trees which is 1.5. So now we take the 1.5 and the 2 hour multiply them and now we have 3. 3 hours is your answer
Answer:
two and one half hours
Step-by-step explanation:
The correct Set-builder form of the set that is written in Roster form is {x|x is an integer and -3≤x≤1}.
<h3>What is an integer?</h3>
An integer is a number that can be written without using a fractional component. Integers such as 21, 4, 0, and 2048 are examples.
The correct Set-builder form of the set that is written in Roster form can be written as,
{x|x is an integer and -3≤x≤1}
Hence, The correct Set-builder form of the set that is written in Roster form is {x|x is an integer and -3≤x≤1}.
