Answer:
2
Step-by-step explanation:
So first you plug 2 in for t
4(2.72)^(-2/2)
4/2.72 (because the simplified exponent is -1)
divide and that's your answer.
Next you plug 1 in for t
4(2.72)^(-1/2)
4/sqrt(2.72) (because -1/2 as an exponent is 1/sqrt(x))
plug that into a calculator and that's your answer
For c, you plug 1 in for V(t).
1=4(2.72)^(-t/2)
1/4=2.72^(-t/2)
Here is where I get stuck because I haven't done logarithms in a year and forget how to do them but I know that's what you have to do for this problem.
In the last problem you plug x in for V(t) and I'd assume go about solving it the same as c. Sorry I couldn't be of more help.
Question:
Which of the following expressions represents the distance between 1.7 and −1/2 on a number line?
Choose 1 answer:


C. None of the above
Answer:

Step-by-step explanation:
Given
Numbers: 1.7 and -1/2
Required
Determine the distance
To calculate the distance, we start by calculating the difference between the given numbers;

Then, we calculate the distance;
<em>In this case, the distance is meant to be positive; So, we'll introduce the symbol for absolute value;</em>
Hence,

Substitute
for Difference;

<em>Hence, the correct option is B</em>
Answer:

Step-by-step explanation:
Given

Required: The base area.
From the question, we have the initial dimensions to be:


h inch were removed from each corner to form the new base. So, the dimension of the new base is:




The area of the base is calculated by multiplying the base dimensions

![Area = [Length - 2h] * [Width - 2h]](https://tex.z-dn.net/?f=Area%20%3D%20%5BLength%20-%202h%5D%20%2A%20%5BWidth%20-%202h%5D)
![Area = [12 - 2h] * [12 - 2h]](https://tex.z-dn.net/?f=Area%20%3D%20%5B12%20-%202h%5D%20%2A%20%5B12%20-%202h%5D)
Expand
![Area = 12[12 - 2h] -2h [12 - 2h]](https://tex.z-dn.net/?f=Area%20%3D%2012%5B12%20-%202h%5D%20-2h%20%5B12%20-%202h%5D)
