**Answer:**

i

**Step-by-step explanation:**

The pattern is as follows

i^1 = i

i^2 = -1

i^3 = -i

i^4 = 1

Following this pattern, i^45 = i.

**Answer:**

Too many answers could be correct

**Step-by-step explanation:**

This one is hard because it will depend on what numbers you pick for each measurement.

-----------------------------------------------------------------------------

if a = 1, b = 2, c = 3, d = 4, and e = 5

find the volume for all the shapes

The post

V = lwh = (1)(1)(2) = 2

The bottom of the mailbox

V = lwh = (3)(4)(5) = 60

The top of the mailbox

V = πr²h = (3)(5)π = 15π = 48.2

Then add them all together:

2 + 60 + 48.2 = 110.2 is the total Volume

**Answer:**

5

**Step-by-step explanation:**

<u>Step 1: Multiply 10 by 0.5</u>

10 * 0.5

5

Answer: **5**

Use the following property above to find the value. Substitute f(x) and g(x) in.

Evaluate/Combine like terms.

This step is optional but it's the best to arrange the degree.

**Answer**

Let me know if you have any doubts!

Oh yeah, so the cubed root is pretty much instead of finding the square root of something (like how sqares are 2 dimensions and you find which number multiplied by itself equals what you are trying to find) the cubed root is just replacing the 2 with a 3. so you would find which number multiplied by itself 3 times equals the main number.

all you need to do is find the volume of those cubes, and then put it into scientific notation (you know, 10 with an exponent multiplied by another number, stuff like that)

I'm so sorry if my explanation is a little all over the place, I hope this helps you out though
