Will say
f(x) =3x^3 + 12^2 + 3x
be the polynomial; two other forms can be obtained by rearranging the terms:
f(x) =3x +12x^ +3x^3
0.4 The process is shown in the following picture
14.4%
L*W*H=V=10*9*4.5=405 in^3.
that is 50.5 in^3 over the estimate, or 14.4%
An=a1+d(n-1)
a1=first term
d=common difference
n=which term
common difference is 5 first term is 2
an=5+2(n-1)
19th term is n=19
a19=5+2(19-1)
a19=5+2(18)
a19=5+36
a19=41
19th term is 41
Find the difference vertically( North and South) and the difference horizontally ( East and West)
Then use the Pythagorean Theorem.
600 North - 200 South = 400 m
400 West - 100 East = 300 m
Now using the Pythagorean Theorem;
400^2 + 300^2 = total displacement^2
Total displacement^2 = 160,000 + 90,000
Total displacement^2 = 250,000
Total displacement = √250,000
Total displacement = 500 m
