3 0

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

or

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

Without using log, Solve for x.<br><br> <img src="https://tex.z-dn.net/?f=27%5E%7B1-x%7D%20%3D%5Cfrac%7B1%7D%7B9%5E%7B2x%7D%20%7

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
