Determine the total number of roots of each polynomial function. f (x) = 3x6 + 2x5 + x4 - 2x3
Oxana [17]

Answer:

6 roots

Step-by-step explanation:

we know that

The number of roots is determined by the degree of the polynomial.  They may be real or complex.

In this problem we have

f(x)=3x^{6}+2x^5+x^4-2x^3

The degree refers to the highest exponent of the polynomial

Since this is a 6th degree polynomial, it will have 6 roots

What is the total surface area??
Olenka [21]

Answer:

216

Step-by-step explanation:

Use geometric formulas to solve for each individual SIDE of the triangular prism

TOP and BOTTOM TRIANGLE sides:

  • \frac{ab}{2}
  • \frac{6(8)}{2}  <--- times 2 because we have TWO identical triangle sides

RIGHT RECTANGULAR side from our perpsective:

  • LxW
  • 8(7)

FRONT RECTANGULAR side:

  • LxW
  • 7(6)

BACK RECTANGULAR side:

  • LxW
  • 7(10)

Now you add all of those formulas together for your answer.

\frac{6(8)}{2} + \frac{6(8)}{2} + 8(7)  + 7(10) + 7(6)

= 216

Line A is represented by the following equation:
Inga [223]
Line A : x + y = 2

The most likely equation for line B so that the set of equation has no solution is: 

x + y = 4

====

x + y = 2
x = 2 - y

2-y + y = 4
0 = 4 - 2
0 ≠ 2

there is no value for x nor y. so, no solution.

6x + 12 -3x =51. <br> Step by step
Liula [17]
Start by combing like terms. You will get 3x+12=51. Now subtract 12 from both sides (3x=39). Divide both sides by 3 (x=13). The answer is 13.
