Answer:
Step-by-step explanation:
Let's break it down:
In the sinusoidal function 
:
represents Amplitude 
represents a constant related to the Period
represents Phase Shift 
represents Vertical Shift
To find Amplitude, divide the entire height of the function (from top to bottom) by two, or find the vertical distance between the horizontal line of symmetry and the highest/lowest point of the wave. In this case, Amplitude is 2.
To find , use 
, where 
is the period of the function. To find the period, count the horizontal distance of the length of one complete cycle. In this case, period is 
and therefore
.
To find Phase Shift, find the horizontal shift from the parent function 
. In this case, there is no phase shift.
To find Vertical Shift, find the vertical shift from the parent function . In this case, vertical shift is -1.
Thus, we've found:
Substituting these values into , we get:
Answer:
No Trend
Step-by-step explanation:
Scatter plots usually have 1 or 2 outlier points if they're to show a positive or negative trend. There is a kind-of negative trend in the graph, but for me personally, I think the outliers kind of cancel the pattern out since there's way to much other points around it. It can't be constant since constant means that the points have to be in one place, and obviously its not really the case here. Therefore, you're left with a no-trend graph!
Name this triangle ABC, where A is the angle divided into equal parts by bisector AD and point B lies under the bisector AD and point C lies over the bisector AD.
According to the bisector theorem:
.
On the picture CD=q and BC=16, then BD=16-q.
The previous ratio becomes:
.
Answer: q=9
