Answer:

x= 1/4

Step-by-step explanation:

First add -2x from both sides leaving you with 3x-3/4=0

Then add 3/4 to both sides leaving you with 3x=3/4

Then divide both sides by 3 giving you x=1/4

State how many imaginary and real zeros the function has.
alukav5142 [94]

Answer:

B. 4 imaginary; 1 real

Step-by-step explanation:

Given the polynomial:

x^5 + 7*x^4 + 2*x^3 + 14*x^2 + x + 7

it can be reordered as follows

(x^5 + 2*x^3 + x ) + (7*x^4  + 14*x^2 + 7)

Taking greatest common factor at each parenthesis

x*(x^4 + 2*x^2 + 1) + 7*(x^4  + 2*x^2 + 1)

Taking again the greatest common factor

(x + 7)*(x^4 + 2*x^2 + 1)

Replacing x^2 = y in the second parenthesis

(x + 7)*(y^2 + 2*y + 1)

(x + 7)*(y + 1)^2

Coming back to x variable

(x + 7)*(x^2 + 1)^2

There are two options to find the roots

(x + 7) = 0

or

(x^2 + 1)^2 = 0 which is the same that (x^2 + 1) = 0

In the former case, x = -7 is the real root.  In the latter, (x^2 + 1) = 0 has no real solution. Therefore, there is only 1 real root in the polynomial.

Evaluate the function f(x) at the given numbers (correct to six decimal places).
3241004551 [841]

Answer:

The function f(x) = \frac{x^{2}-4\cdot x}{x^{2}-16} has the following set of solutions:

f(4.1) = 0.506173, f(4.05) = 0.503106, f(4.01) = 0.500624, f(4.001) = 0.500062, f(4.0001) = 0.500006, f(4.0001) = 0.500006

f(3.9) = 0.493671, f(3.95) = 0.496855, f(3.99) = 0.499374, f(3.999) = 0.499937, f(3.9999) = 0.499994

Step-by-step explanation:

Let be f(x) = \frac{x^{2}-4\cdot x}{x^{2}-16}, we proceed to simplify the expression by Algebraic means:

1) \frac{x^{2}-4\cdot x}{x^{2}-16} Given

2) \frac{x\cdot (x-4)}{(x-4)\cdot (x+4)} Associative, commutative and distributive properties/a^{2}-b^{2} = (a+b)\cdot (a - b)

3) \frac{x}{x + 4} Commutative, associative and modulative properties/Existence of multiplicative inverse/Result

Now we evaluate the function for each value:

x = 4.1

f(4.1) = \frac{4.1}{4.1+4}

f(4.1) = 0.506173

x = 4.05

f(4.05)  = \frac{4.05}{4.05 + 4}

f(4.05) = 0.503106

x = 4.01

f(4.01) = \frac{4.01}{4.01 + 4}

f(4.01) = 0.500624

x = 4.001

f(4.001) = \frac{4.001}{4.001+4}

f(4.001) = 0.500062

x = 4.0001

f(4.0001) = \frac{4.0001}{4.0001 + 4}

f(4.0001) = 0.500006

x = 3.9

f(3.9) = \frac{3.9}{3.9+4}

f(3.9) = 0.493671

x = 3.95

f(3.95) = \frac{3.95}{3.95+4}

f(3.95) = 0.496855

x = 3.99

f(3.99) = \frac{3.99}{3.99+4}

f(3.99) = 0.499374

x = 3.999

f(3.999) = \frac{3.999}{3.999 + 4}

f(3.999) = 0.499937

x = 3.9999

f(3.9999) = \frac{3.9999}{3.9999 + 4}

f(3.9999) = 0.499994
