What is the solution to ln (x2 - 16) = 0?

bogdanovich [222]

ANSWER

$x = \pm \sqrt{17}$
EXPLANATION

The given equation is

$ln( {x}^{2} - 16) = 0$

Take antilogarithm of both sides to base e.

${e}^{ ln( {x}^{2} - 16) } = {e}^{0}$

This will simplify to

${x}^{2} - 16 = 1$

Group like terms to obtain,

${x}^{2} = 1 + 16$

${x}^{2} = 17$

Take square root of both sides to get,

$x = \pm \sqrt{17}$

A flock of 200 birds were flying south for the winter. Every day, the amount of birds in the flock increased by an average of 4%

astra-53 [7]

Answer:

$b=200(1.04)^{d}$

Step-by-step explanation:

we know that

The exponential function is of the form

$y=a(b)^{x}$

where

a is the initial value

b is the base

In this problem we have

a=200 birds

b=100%+4%=104%=104/100=1.04

substitute

$y=200(1.04)^{x}$

Let change of variables

$b=200(1.04)^{d}$

where

b is the amount of birds in the flock

d is the number of days since the 200 birds started

Three yards of fabric will be cut into pieces so that each piece is 8 inches long. How many pieces can be cut? (1 yard = 36 inch

In-s [12.5K]

You have 3 yards and each piece of fabric needs to be 8inches long. Convert yards into inches. Divide it by 8.

3yds= 108 inches
108/8= 13.5

You can cut 13.5 pieces of fabric.

Have a good day :)
