The graph forms a straight line going downwards. The straight line means that the speed is constant. It is going downwards meaning it is stopping.
The best statement that represents the graph is:
<span>Each point shows the remaining distance, in feet, to the finish line of a race t seconds after a runner begins the final stretch and runs at a constant speed.</span>
Vertex: (3,-65) axis of Symmetry: x = 3
The trigonometric ratios are used for right angle triangle.The basic rule to followed is SOH CAH TOA
SOH means Sinx=opposite/Hyp.
CAH means Cosx = adj./Hyp.
TOA means Tanx = Opp./Adj.
Opposite is the side opposite to the acute angle of the right triangle.
<span>Adjacent is the side Adjacent to the acute angle of the right triangle.
</span>
The longest side in a right triangle is the hypotenuse.
Canceling units is also called unit analysis.
This is also called dimensional analysis.
What is a unit of analysis in statistics?
- The unit of analysis is the entity that you're analyzing. It's called this because it's your analysis (what you want to examine) that determines what this unit is, rather than the data itself.
- Because it is the analysis you do in your study that determines what the unit is.
- For instance, if you are comparing the children in two classrooms on achievement test scores, the unit is the individual child because you have a score for each child.
For example -
1 ft = 12 in
3 ft = 
3 ft = ( 3 * 12 ) in ⇒ 36 in

The height of the Washington monument is 555.146.
I got this by using trigonometry “tan(77) • 118”
