f (x) = x ^ 4-x ^ 3 + x ^ 2-x
For this case what we can do is graph the function and see the behavior of it.
We have then that the function grows upwards (see attached image)
It has two cutting points with the x axis in:
x = 0
x = 1
Therefore, the other roots of the polynomial are imaginary.
Answer: 2 x intercepts appear on the graph of this polynomial function
The 3rd one, dear. hope this helped.
Answer:
Only Annabelle is correct.
Step-by-step explanation:
So we have the expression:
![(4^27^5)(4^37^2)](https://tex.z-dn.net/?f=%284%5E27%5E5%29%284%5E37%5E2%29)
When multiplying exponents with the same base, we can use the following property:
![x^ax^b=x^{a+b}](https://tex.z-dn.net/?f=x%5Eax%5Eb%3Dx%5E%7Ba%2Bb%7D)
Essentially, we add the exponents together.
So, first group them:
![=(4^24^3)(7^57^2)](https://tex.z-dn.net/?f=%3D%284%5E24%5E3%29%287%5E57%5E2%29)
Use the property:
![=4^{2+3}7^{5+2}](https://tex.z-dn.net/?f=%3D4%5E%7B2%2B3%7D7%5E%7B5%2B2%7D)
And so our answer is:
![=4^57^7](https://tex.z-dn.net/?f=%3D4%5E57%5E7)
So, Annabelle's answer is correct.
Navene incorrectly used the property. The property adds the exponents, it doesn't multiply them.
So, only Annabelle is correct.
And that's our answer :)
P.S. Congratulations on finishing!

Step-by-step explanation:
Answer:
130356 grams.
Step-by-step explanation:
The table shown in the picture is a proportion table. What I did here was divide 34932 by 4.1. That gave me 8520. So, 1 cm³ of metal is 8520 grams. Now multiply that by 15.3.
8520/1 * 153/10
<em>Cross-cancellation (8520 becomes 852, 10 becomes 1 (GCF: 10))</em>
852 * 153
<em>Multiply 852 by 153 to get 130356.</em>
130356
15.3 cm³ of metal weighs 130,356 grams.
<em>(Long multiplication work is below.</em>
