Math 11 Edublog Post #2

This week the thing that I learned in class that I found the most interesting was how to find the sum of an infinite geometric series. For a geometric series to be infinite the common ratio (r) has to be greater than -1 and less than 1 (Ex. 0.89).

The equation to find the sum of an infinite geometric series you have to use the following equation

a/1-r

if we had a series with the 1st term being 3 and the difference being 0.72 then the equation would look like the following.

3/1-0.72

 

3/-.28

 

-10.71

This week I learned a lot of new things but one that stood out was finding out how to add up all the numbers in a arithmetic sequence. The formula we use is below.

S_n=(t_1+t_n)\cdot (n\div2)

In a sequence such as 1,3,5,7,9 to find S_{23} you would have to use the above equation as well as and equation to find t_{23} the solution is as follows in the picture of my work.

 

Why marihuana should be legal

I think it should be legal because of all the Benifits such as it’s mdical use because it fights cancer cells and it is way better than taking prescription drugs for chronic pain.  It is also so great for epilepsy patients. If it was legal the government could control what’s in the substance and could also capitalize on it. If it were to stay illigal it is not stoping anyone from getting there hands on it. It is less harmful than cigarettes and it has benifits.

Kaleb and Liam’s Rube Goldberg Project

Blue prints/brainstorm of our project

A: The phone vibrates down the ramp hitting a marble that s on a stop that turns potential energy into kenetic a energy as it goes down a ramp hitting a lever.

B: A marble hits the bottom the lever witch hits the car above.

C: The car travels down a ramp over the chair falling in a basket.

D: The car fals in the basket lifting a lever that is blocking a large marble.

E: The marble is re-elected and rolls down a woden path.

F: The marble falls on the mouse trap witch lets the flag go.

G: The weights on the other side of the tower drag the flag up.(raising the flag)

ENERGY TRANSFERS

1 section A when potential energy turns into kenetick energy with the marble.

2 section C-D when kenetic energy turns into more kenetic energy with the lever

3 section f the mouse trap uses elastic energy and is set off using kenetic energy

Making babies 101

Remain and I created a Baby in our science class. The way we did this so by flipping a coin to decide who had the dominant trait and other factors to decide traits of the baby. Our baby has blue eyes and wavy hair he also has pointy nostrils. In a way this is similar to real life because we get traits from both of our parents but in real life the way we are maid is much more complicated than a coin flip. At points during this experience I realized that I prefer certain traits such as detached eyebrows rather than a unibrow. I think my preferences come from my life and what we are thought is “attractive” and “normal” even though it is all normal.
