Answer:
P(x) =x³-4x²-31x+70
Step-by-step explanation:
The function is expressed as:
P(x) = (x+5)(x-2)(x-7)
P(x) =(x²-2x+5x-10)(x-7)
P(x) = (x²+3x-10)(x-7)
P(x) = x³-7x²+3x²-21x-10x+70
P(x) =x³-4x²-31x+70
Hence the polynomial is P(x) =x³-4x²-31x+70
In order to find average rate of change over an interval, do the y2-y1/x2-x1. Solve y for x=9 and x= 4
y2 = -3(9-4)^2 + 3 = -72
y1 = -3(4-4)^2 + 3 = 3
Now, x2 matches with y2 and and x1 matches with y1 obviously...
-72 - 3/9 - 4 = -15
-5 =

- 2
equals x = -4.
First, simplify

to

. / Your problem should look like: -5 =

- 2.
Second, multiply both sides by 4. / Your problem should look like: -20 = 3x -8.
Third, add 8 to both sides. / Your problem should look like: -20 + 8 = 3x.
Fourth, simplify -20 + 8 to -12. / Your problem should look like: -12 = 3x.
Fifth, divide both sides by 3. / Your problem should look like:

= x.
Sixth, simplify

to 4. / Your problem should look like: -4 = x.
Seventh, switch sides. / Your problem should look like: x = -4, which is your answer.
If 100% = 1.00, then 28.2% is 0.282.
So, if you want 28.2% of 92, you need to multiply 92 by 0.282.
Therefore:
92 x 0.282 = 25.944
