Hello,
P(x)=x^3-7x-6
P(4)=4^3-7*4-6=30
Remainder=30
N would equal 28 since 60-32 is 28
ANSWER
The vertex of the graph of

is

EXPLANATION
The vertex form of a parabola is given by

where

is the vertex of the parabola.
The function given to us is

This is already in the vertex form.
When we compare this to the general vertex form, we have,


and

Therefore the vertex of the parabola is

Hence the correct answer is option A.
The answer is 52,000.
You have to add all of the values and divide them by the number of values. In this case you would do 30,000 + 50,000 + 30,000 + 80,000 + 70,000 which equals 260,000 then you would divide that number by 5 since there are 5 values.
#2 is 5
#3 is 18.9
#4 is 14.1
#14 is yes it does
