Answer:
D. 348
Step-by-step explanation:
The volume of the square prisma is given by the following formula:
In which h is the height, and s is the side of the base.
Let's use implicit derivatives to solve this problem:
In this problem, we have that:
So
So the correct answer is:
D. 348
1. 2.27 x 10^-3...when u have a negative exponent, u move the decimal to the left....and since the exponent is -3, u move the decimal 3 spaces to the left.
answer would be : 0.00227. Or the longer way would be : 2.27 * 1/10^3...because if u have a negative exponent, change it to positive and stick it under 1....so 2.27 * 1/10^3 = 2.27/10^3 = 2.27/1000 = 0.00227.
2. 3.772 x 10^5...if the exponent is positive, u move the decimal to the right...and since the exponent is 5...move the decimal 5 spaces to the right....answer would be : 377200...or u could just do 3.772 * 100,000 = 377,200.
3. 9.7 x 10^1 = move decimal to right 1 space = 97
4. 1.33586 x 10^6 = move decimal to right 6 spaces = 1,335,860
5. 1.33586 x 10^-5 = move decimal to left 5 spaces = 0.0000133586
6. 4.22 x 10^-1 = move decimal to the left 1 space = 0.422
They cancel out each other
Imagine if you were multiplying
-2 * -3
you would get 6
if you did
-2 * 3
you would get -6 because there isn't another - to cancel it out
I learned it that when you have a negative before a negative, put parenthesis around the second number with the negative, so it looks like this
-(-2)
if you look at the -(- it looks like a plus sign
that probably doesn't make much sense but we cancelling it out is just a rule, we don't really know why we do it
