## Pre-Calc 11 Week #2

This week I learned about finite geometric series and how to find the general term ($t_n$) along with how to find the sum of whatever the term number is.

To find $t_n$, you need $t_1$ and the common ratio

In this example I’m looking for $t_{13}$ with a $t_1$ of 5 and a common ratio of 2

And in this next example I show how to find $S_{13}$ with the same numbers.

## Pre-Calc 11 Week #1

This week in Pre-Calc 11 we learned how to use the patterns in arithmetic sequences and series to find a number later in the series/sequence.

Basically if $t_1$ is 4 and $t_2$ is 8 we can tell the common difference is +4 using the common difference we can find any number after.

In this example I’ll show how to get $t_{35}$ using the information found

Explanation of all the steps:

A little lego guy (A) is released from a wooden tower down a zip line and hits the marble ball (B) down the wooden ramp (C) after the ball goes to the end of the wooden ramp it will fall into the paper cup (D) and will come out the bottom which will make it land on the set mous trap (E) once the mouse trap goes off it will hit the dominos (F) and they will all fall which will cause the marble (G) on the wood ramp to roll down and hit the next set of dominos (H) once they go off they will cause the tennis ball (I) to fall into the plastic cup (J) and out of the bottom hole onto a binder/ ramp (K) which will then hit the upside down bottle (L) at the end forcing it to be hit off the chair and onto the ground where the duck tape will catch it and make it land on its cap.

Energy Transfers:
(A) Kinetic to (gravitational) Potential
When the lego man is going down (kinetic) the zip line he stops ( potential) when he hits the marble.

(E) Kinetic to Sound/ Elastic

When the marble falls (kinetic) onto the mouse trap it creates a loud sound (sound).

When the marble falls (kinetic) onto the mouse trap it the spring (elastic) closes the mouse trap.
(G)Potential to Kinetic

When the marble is still (potential) It is then hit by the dominos causing it to move (kinetic) down the ramp.

## Making babies

The babies name is Junior he has dark blue eyes, a cleft chin, curly black hair, he is dark skinned, and has a regular nose. These traits were given by his parents because they had a lot of these traits.

3. Answer the following questions:

a. How does the coin flip relate to the probability of inheriting genetic conditions?

Its 50/50 like how the the genes are 50/50 between parents

b. How does this simulation accurately represent or not represent real life?

It accurately represents the chances of getting each gene. It shows the chance of getting different traits on a baby which represents how a baby might be in real life off dominant genes.

c. Did you identify any prejudices you might have about what traits you find “desirable”? Where do you think these prejudices come from?

I had prejudices as I did not like the very pointy chin with square head. I think these prejudices come from our idea of normal and/or what looks good

## Egg recipe: Take home lab

This is a take home lab that was assigned to my Foods 10 class, over our spring break. We were told to chose three recipes and to try at least one of them. The recipe(s) you chose was graded/marked by a guardian of your chose. The sheet that was marked was handed in the first day back to school from Spring break.

I chose to do a Egg Masala which I’ve seen my mom make many times. I personally don’t like egg that much and did not end up eating it, so i had my parents and sisters taste who said it tasted good. I did however try it and think it needed to be less oily.

Ingredients

1 Potatoe

4 Boiled eggs

70 ml of vegetable oil

1 whole onion

500ml Water

Steps

1. Get water boiling and add the eggs for 6 mins to let them boil
2. Get oil heating on a pan at medium heat
3. Peel and cut Onion, Garlic and Potato and cook them at medium heat until the onions and garlic are translucent
4. Cut tomatos into small squares
5. Mix curry powder with water and put in big pot
6. Add everything to the pot and mix ginger, salt and red chili
7. Enjoy
