1) Answer 4.
Explanation.
The number of total roots of a polynomial is the degree of the polynomial. In this case it is 4.
The real, i.e. non-complex roots of a polynomial correspond to the x-intercepts of the graph. Then you can graph the polyomial to see how many real roots it has.
The graph of this polynomial shows that it does not cross or touch the x-axys which means that there are not real roots. Thereafter the 4 roots are complex.
2) The multiplicity of a root is the number of times that the corresponding factor appears in the polynomial. In this case the factor x + 1 appears two times, then - 1 has multiplicity 2.
3) You can either graph the polynomial or factor it.
If you factor it you will find:
x^4 - x^3 - 9x^2+7x+14 = (x +1)(x -2)(x^2 -7).
The there are 4 zeroes or 4 real roots.
Step-by-step explanation:
1 page = 3 baseball cards
8 pages = 3 * 8 = 24 baseball cards.
We can represent this on the number line by putting a solid dot above the number 24 along the axis.
Answer:
8p
Step-by-step explanation:
5p-4=3p+6
-3p from 5p
2p-4=6
+4 at 4 to the 6
2p=10
divide 2p=10
8p
this should be right but not 100% thanks for the points
Answer:
Building A is taller. it is around 50.34 feet taller than building B
Step-by-step explanation:
Refer the attached figure
We are given that Kayson is looking at two buildings,building A and building B, at an angle of elevation of 40°.
Building A is 120 feet away.
BC =120 feet
Building B is 60 feet away.
BE= 60 feet
In ΔABC
In ΔDBE
50.34=DE
Difference between their heights=100.68-50.34=50.34
So, Building A is taller. it is around 50.34 feet taller than building B
