Answer:

B. 1 + ln 2 - ln x

General Formulas and Concepts:

<u>Algebra II</u>

  • Natural logarithms ln and Euler's number e
  • Logarithmic Property [Multiplying]:                                                                     \displaystyle log(ab) = log(a) + log(b)
  • Logarithmic Property [Dividing]:                                                                         \displaystyle log(\frac{a}{b}) = log(a) - log(b)<u> </u>

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

<em />\displaystyle ln(\frac{2e}{x})<em />

<em />

<u>Step 2: Simplify</u>

  1. Expand [Logarithmic Property - Dividing]:                                                      \displaystyle ln(\frac{2e}{x}) = ln(2e) - ln(x)
  2. Expand [Logarithmic Property - Multiplying]:                                                  \displaystyle ln(\frac{2e}{x}) = ln(2) + ln(e) - ln(x)
  3. Simplify:                                                                                                             \displaystyle ln(\frac{2e}{x}) = ln(2) + 1 - ln(x)
  4. Rewrite:                                                                                                             \displaystyle ln(\frac{2e}{x}) = 1 + ln(2) - ln(x)

The distance from the Earth to the moon is about 239,000 miles. Rewrite the distance in scientific notation.
egoroff_w [7]

Answer:

2.39 x 10^5 miles

Step-by-step explanation:

Although it is not usually written, there is always a .0 at the end of a number unless there is a specific decimal that was given.

So, the number here is 239,000.0 and if you count the number of spaces that the decimal needs to move in order to be in the correct spot for scientific notation (which is always after the first number), there is 5 spaces.

Therefore the answer is 2.39 x 10^5 miles.

A circle has a diameter of 4 meters.
Slav-nsk [51]

Answer:

Step-by-step explanation:

r = d/2

r = 4/2

r = 2

pi = 3.14

Circumference = 2 * pi * r

Circumference = 2 * 3.14 * 2

Circumference = 12.56

Area = pi r^2

Area = 3.14 * 2^2

Area = 4 * 3.14

Area = 12.56

Ghella [55]

Answer:

Triangular Prism Volume : 560 ft³, Rectangular Prism Volume: 1,400 ft³, and Total Volume of the Composite Figure: 1,960 ft³

Step-by-step explanation:

Triangular Prism Volume Formula: 1/2(L)(W)(H)

1/2(10)(14)(8)

= 560 ft³

Rectangular Prism Volume: L x W x H

10 x 14 x 10

= 1,400 ft³

1,400 ft³ + 560 ft³

= Total Volume of the Composite Figure: 1,960 ft³
