Can u pls show the picture so that I can solve the problem?
Thx
Answer:
ANSWER: 30
ANGLE BCD IS MADE UP OF 180 DEGREES ANGLE C IS 120 AND SINCE THE ENTIRE ANGLE IS 180 AND C AND D IS CONGRUENT AND 60 DEGREES IS LEFT WE DIVIDE BY 2 TO FIND OUR ANSWER OF 3O
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.
16. M = 1/5
17. M =3
18. Slope 1/4 and y-intercept (0,2)
