Answer:

correct answer is x = 2.75

Step-by-step explanation:

Given;

AB = 2x-5

BC = 6x

AC = 27

Hence,

=> AC = AB + BC

=> 27 = 2x-5 + 6x

=> 27 = 8x-5

=> 27-5 = 8x

=> 22 = 8x

=> 22/8 = x

=> 11/4 = x

2.75 = x

Determine whether the improper integral converges or diverges, and find the value of each that converges.

Vanyuwa [196]

Answer:

The integral diverges

Step-by-step explanation:

Consider the integral from 0 to infinity of

$xe^{4x}$

We can do this in parts

$\int {xe^{4x} } \, dx =\int {x} \, d(e^{4x})/4\\ = x/4 e^{4x}-e^{4x}/16$

When we substitute limits infinity we find that the values become infinity

Hence the integral diverges

The given improper integral diverges

ANSWER

$x = - 3$

EXPLANATION

The given equation is

$27^{1-x} =\frac{1}{9^{2x} }$

Recall that

$\frac{1}{ {a}^{m} } = {a}^{ - m}$

Apply this rule on the right hand side to get,

$27^{1-x} =9^{ - 2x}$

Express both sides to base 3.

$3^{3(1-x)} =3^{2( - 2x)}$

Equate the exponents:

3(1-x)=2(-2x)

Expand:

$3 - 3x = - 4x$

Group like terms,

$4x - 3x = - 3$

$x = - 3$
