Answer: x=0.168

Step-by-step explanation:

To solve the equation e^{2x}=1.4 you need to apply natural logarithm to both sides of the equation:

ln(e)^{2x}=ln(1.4)

According to the logarithms property:

ln(b)^a=aln(b)

Then, applying the property, you get:

(2x)ln(e)=ln(1.4)

You need to remember the following:

ln(e)=1

Therefore:

2x(1)=ln(1.4)\\\\2x=ln(1.4)

And finally, you must divide both sides of the equation by 2:

\frac{2x}{2}=\frac{ln(1.4)}{2}\\\\x=0.1682

Rounded to the nearest thousand:

x=0.168

Answer:

x = 0.16823611831

Step-by-step explanation:

ln (natural log), when multiplied by e, cancels it out.

Therefore ln*e2x = ln*1.4

2x = 0.33647223662

x = 0.16823611831

Find the length of each segment. SEE EXAMPLES 1 AND 2
wlad13 [49]

The lengths of the line segments are summarized in the following list:

  1. DF = 3
  2. DE = 8 / 3
  3. FG = 3
  4. FH = 9 / 2
  5. GH = 3 / 2
  6. EH = - 11 / 6
<h3>How to calculate the length of a line segment based on point set on a number line</h3>

Herein we have a number line with five points whose locations are known.  The length of each line segment is equal to the arithmetical difference of the coordinates of the rightmost point and the leftmost point:

DF = - 1 - (- 4)

DF = 3

DE = (- 1 - 1 / 3) - (- 4)

DE = 3 - 1 / 3

DE = 8 / 3

FG = 2 - (- 1)

FG = 3

FH = (3 + 1 / 2) - (- 1)

FH = 4 + 1 / 2

FH = 9 / 2

GH = (3 + 1 / 2) - 2

GH = 1 + 1 / 2

GH = 3 / 2

EH = (3 + 1 / 2) + (- 1 - 1 / 3)

EH = - 2 + (1 / 2 - 1 / 3)

EH = - 2 + 1 / 6

EH = - 11 / 6
