Review of Math 10

5 Things I learned in Math 10 this year

  1. Practice is key with math. Do the homework to prepare for your tests. Doing the homework will help you be more quick and successful in the unit.
  2. Every unit we did in this class is the foundation to help understand future math courses. Make sure you understand everything.
  3. Finishing your blog posts as soon as possible helps free you from the stress of 11pm Sunday night rush.
  4. Pay attention to all the lessons and take notes. Ask questions!
  5.  Zoning out during a test is problematic.

His Secret

“His Secret” A Poem by Nighina Rahimi

Her hand falls across his back,

His skin paints blue and black,

Scrapped, cut, bruised, scarred, cracked.

 

Her screams make the room shutter,

A prayer is muttered,

Hoping he didn’t stutter.

 

Degrading him and putting him in dirt,

Watching as he whimpers, hurt,

Hollow under the blood-stained nightshirt.

 

He never knew of her assaulting ways,

When he vowed to everlasting loving days,

To cherish her through thick and thin and never stray.

 

Everything changes when the doors are closed,

Everything is different when nothing is exposed,

Everything was left, unopposed.

 

The pain flowing across his cheek, concealed by the fragility of masculinity.

Alone, hidden by shame and lost from sincerity,

Hardly listened to, hardly heard, no sympathy.

 

He wants to run and hide, scream out a name,

But he screams silence and hides in his shame,

And his future seems like an empty grave.

 

Would anyone understand,

Would they give him a helping hand,

To escape his past dreamland.

 

Expectation to be the man,

To be the strongman, muscles galore and power in his hold,

Not the one that ran to cover in times of fear.

 

Well, the wounds no longer let him meet the expectation,

There is no makeup to cover these damnations,

He remains pent up with frustration.

 

Frustration because he knows no one out there will believe him,

They will misperceive him,

And leave him without compassionate relief for him.

 

Like a fish, half-dead from flopping,

But almost crawling,

Views can change, freedom might be a possibility.

 

But then she tightens her grip,

Making sure he doesn’t let anything slip,

About her cruel, demeaning lip.

 

His grave is dug deeper day by day,

The secret is stowed away,

He can’t breathe, 6 feet under the decay.

 

The pain will linger on his skin,

The bruises won’t diminish from within,

Her maltreatment continues for him.

 

So, hidden away,

Under her grip, unspoken of the abuse, he stays,

Praying for the bright sunlight of a new day.

 

Society judges the same,

She remains insane,

Hope is losing its name.

 

His hope is diminished, rotting away,

Leaving him empty without the faith of any change in the societal ways,

Left, misunderstood, to take his secret to his grave.

Performance

This lyric poem “His Secret” by Nighina Rahimi captures the taboo of domestic abuse facing men and the fear and judgement when wanting to speak up. The poem focuses mainly on the theme of gender stereotypes and their negative consequences and the societal expectations and how that can impact how we see and define ourselves. Her poem attacks the question, “Why do people feel the need to conform to society and its expectations?” She points out the difficulties and struggles for men that deal with abuse. Aside from the fact that they are being physical and emotional harmed, society can be one sided. The stereotypes begin with the expectation that men have the control over their woman. They have possession and strength. When you hear about abusive relationships, the mind always think first that the woman is the one in trouble. A man abused never comes to mind.  These stereotypes and expectations created by society become problematic because more than 40% of domestic violence victims are males in North America, and they all fear seeking help in fear of being mocked and judged by a society who doesn’t understand this is a possibility. They don’t see men being abused as a possibility because it is so unheard of. The issue she shares using well-chosen words help enlighten others to the serious problem that is concealed by many men out of fear. Nighina refers to the video “Miss representation,” another informer of the cruel effects of stereotypes and how fragile masculinity can be and how that and the stereotypes can be problematic.

 

Week 15 – Slope

Slope is the measure of steepness of a line. Slope is the ratio of the vertical change (rise) over the horizontal change (run).

A line segment which rises from left to right has a positive slope.

A line segment which rises from right to left has a negative slope.

The rise is positive if we count up, and negative if we count down.

The run is positive is we count right, and negative is we count left.

A horizontal line segment has a slope of 0.

A vertical line segment has an undefined slope.

The slopes of all line segments on a line are equal.

Slope Formula

m represents slope. Slope Formula is used to find the slope when given two coordinates, without graphing them.

The Formula = 

Example

Find the slope of A(-3, -8) and B(1, 5)

Week 13 – Domain and Range

The Domain of a relation is the set of all possible values which can be used for the input of the independent variable (x).

The Range of a relation is the set of all possible values of the output of the dependent variable (y).

The Domain and Range can be found by listing the inputs and outputs.

Ordered pairs

(1,2), (0,5), (3,8), (5,9) (-3,2)

Domain: {-3, 0, 1, 3, 5}

Range: {2, 5, 8, 9}

An Arrow Diagram

D: {2, 4, 6, 8}

R: {1, 3, 5}

Graph

D: {-1, 0, 3, 4}

R: {5, 0, 2, 1}

D: {x E R}

R: {y E R}

D:  {x|-4 ≤ x ≤4, x ∈ R}

D: [-4, 4]

R: {y|0 ≤ y ≤ 5, y ∈ R}

R: [0, 5]

 

Week 12 – Relationship Between Two Quantities

A comparison between two sets of elements is called a relation.

Relations can be represented

In Words

“The cost, C, of driving a car is related to the speed, s, at which it is driven.”

A Table of Values

A Set of Ordered Pairs

(20,10)

(30,9.1)

(40,8.4)

A Mapping or Arrow Diagram

An Equation 

C = 0.001s^2 – 0.14s + 12.4

A Graph

Independent Variable represents the inputs

The Corresponding Value – Dependent Variable represents the outputs

In an ordered pair, the values of the first coordinate are the independent values. The value of the second coordinate is therefore the dependent value.

Usually, the first given number in a table of values is the independent value, to the left of above the values of the following number, the dependent value.

In a mapping diagram, the arrows go from the independent value to the dependent value.

In a graph, the horizontal axis (x-axis) has the independent values, and the vertical axis (y-axis)  is the dependent values.

In an equation, usually, the dependent variable is isolated on the left side.
