Answer: 8.50 dollars

The result is positive, so this is a gain (instead of a loss)

====================================

Explanation:

Focus on the "stock JKL" row only when it comes to the percentages we'll use. We need to convert them to decimal form

15% ---> 0.15

65% ---> 0.65

20% ---> 0.20

I just moved the decimal point over 2 spots, or you can divide by 100 (eg: 15% = 15/100 = 0.15)

Multiply each of these values by their corresponding loss or gain. Use negative numbers for losses

15% chance of losing $25 ---> 0.15*(-25) = -3.75

65% chance of winning $5 ---> 0.65*(5) = 3.25

20% chance of winning $45 ---> 0.20*(45) = 9

Now add up those results: -3.75+3.25+9 = 8.50

What is the perimeter of the polygon? Do not round any side lengths. Please help me.
DanielleElmas [232]

The easiest way to do this is to plot the points. I used the pythagorean theorem for this one, too. Add the side lengths to get the perimeter: 5 + 5 + 5 + 3 + √40 = 24.32455532 units or just 24 units.

Homework Jim Thompson! PART 2

Problem 2

Part (a)

The 3D shape formed when rotating around the y axis forms a pencil tip

The shape formed when rotating around the x axis is a truncated cone turned on its side.

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

Part (b)

Check out the two diagrams below.

============================================================

Problem 3

Answer: Choice A and Choice C

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

Explanation:

Think of stacks of coins. Let's say we had 2 stacks of 10 quarters each. The quarters are identical, so they must produce identical volumes. Those sub-volumes then add up to the same volume for each stack. Now imagine one stack is perfectly aligned and the other stack is a bit crooked. Has the volume changed for the crooked stack? No, it hasn't. We're still dealing with the same amount of coins and they yield the same volume.

For more information, check out Cavalieri's Principle.

With all that in mind, this leads us to choice C. If the bases are the same, and so are the heights, then we must be dealing with the same volumes.

On the other hand, if one base is wider (while the heights are still equal) then the wider based block is going to have more volume. This leads us to choice A.

Answer:

060.28

Step-by-step explanation:

3 can't go into 1, but it goes into 18 six times with 0 left over. 3 goes into 0 zero times. 3 goes into 5 one time with 2 left over. 3 goes into 26 (because you pull the 6 down) 8 times with 2 left over.
