Answer:
Step-by-step explanation:
Polynomial f(x) has the following conditions: zeros of -4 (multiplicity 3), 1 (multiplicity 1), and with f(0) = 320.
The first part zeros of -4 means (x+4) and multiplicity 3 means (x+4)^3.
The second part zeros of 1 means (x-1) and multiplicity 1 means (x-1).
The third part f(0) = 320 means substituting x=0 into (x+4)^3*(x-1)*k =320
(0+4)^3*(0-1)*k = 320
-64k = 320
k = -5
Combining all three conditions, f(x)
= -5(x+4)^3*(x-1)
= -5(x^3 + 3*4*x^2 + 3*4*4*x + 4^3)(x-1)
= -5(x^4 + 12x^3 + 48x^2 + 64x - x^3 - 12x^2 - 48x - 64)
= -5(x^4 + 11x^3 + 36x^2 + 16x -64)
= -5x^3 -55x^3 - 180x^2 - 80x + 320
I think that when you asked this question, no one answered because there is not enough information. I also got this problem and there is in fact, a table and a graph.
Step-by-step explanation:
for Hector, it only shows a y and x graph and for Geri it shows a table. let´s call the graph the ¨h¨ graph (for Hector) and the table is going to be called the ¨g¨ graph (for Geri)
on the h graph, it shows that y/x = dollars/time for Hector,
on the g table, it shows that Geri is getting paid $25.50 for each 3 hours and it keeps increasing within each input and output.
your y = your dollars
your x = your time
we are looking for slope and we need $15 over hours
15/x
the answer is that Hector earns $6.50 more than Geri
2*1.4=2.8
1.5*1.4= 2.1
New figure: 2.8 by 2.1
You just need to see if you can isolate the y-variable.
