Answer:
=−18y4−27y3+81y2
Step-by-step explanation:
(40+80) + (8+2)
120+10
130
your answer would be 130
you group 40 and 80 and get the answer and then group 8 and 2
get answer to both then and then you add them together for the answer
The results of the survey will most likely suffer from wording bias.
<h3><u>Wording Bias</u></h3>
The question asked in the survey contains certain characteristics that induce the respondent to think about the question asked in a negative way.
Thus, the word "wasteful" induces respondents to answer the question bearing in mind the negative criticism made by the questioner, which may influence the final answer.

Answer:
Step-by-step explanation:
To define the perpendicular line we need to first know the slope of the reference line graphed.
m=(y2-y1)/(x2-x1) we have points (0,5) and (2,1)
m=(1-5)/(2-0)
m=-4/2
m=-2
For lines to be perpendicular their slopes must satisfy
m1m2=-1, we have a line with a slope of -2 so
-2m=-1
m=1/2, so our perpendicular line is so far
y=x/2+b, it must have point (3,2) so we can solve for b
2=3/2+b
b=1/2, so the swimmer will travel along the line
y=x/2+1/2
