Answer:

The Height of the cliff is 41.5 meters tall.

Option B. 41.5 meters.

Step-by-step explanation:

Given:

AB = 85 meter

Angle of elevation ∠ C= 26°

To Find:

Cliff height = AB = ?

Solution:

In right angle Triangle ABC by tangent Identity we have

\tan C = \frac{\textrm{side opposite to angle C}}{\textrm{side adjacent to angle C}}

Substituting the given values we get

\tan 26 = \frac{AB}{BC}=\frac{AB}{85}

\therefore AB=85\times 0.4877=41.45=41.5\ meters

The Height of the cliff is 41.5 meters tall.

• a descriptive metaphor
• a humorous play on words
• an illuminating allusion


5. In the last paragraph the narrator says his mother would “fetch out a long word.” The connotations of the word fetch remind the reader that the narrator’s mother —

• knows lots of big words
• likes to show off


8. What is ironic about the author’s mother showing off with her knowledge of the word unintellectual?

• Her child knew she didn’t understand the word correctly.

• The strangers all already knew the meaning of the word.

• As any intellectual would know, the word should be “nonintellectual.”

Solve the equation. 7+3lnx=20
siniylev [52]

Answer:

Simplifying

7 + 3lnx = 15

Solving

7 + 3lnx = 15

Solving for variable 'l'.

Move all terms containing l to the left, all other terms to the right.

Add '-7' to each side of the equation.

7 + -7 + 3lnx = 15 + -7

Combine like terms: 7 + -7 = 0

0 + 3lnx = 15 + -7

3lnx = 15 + -7

Combine like terms: 15 + -7 = 8

3lnx = 8

Divide each side by '3nx'.

l = 2.666666667n-1x-1

Simplifying

l = 2.666666667n-1x-1

What is the area of a rectangle with a width of x2 + x + 1 and a length of<br> 3x2 - 2x - 1?
nata0808 [166]

Answer:

x^{4} + 3x³ - 3x - 1

Step-by-step explanation:

The area (A) of a rectangle is calculated as

A = lw ( l is the length and w the width ) , thus

A = (3x² - 2x - 1)(x² + x + 1)

Each term in the second factor is multiplied by each term in the first factor, then

A = 3x²(x² + x + 1) - 2x(x² + x + 1) - 1(x² + x + 1) ← distribute parenthesis

   = 3x^{4} + 3x³ + 3x² - 2x^{4} - 2x² - 2x - x² - x - 1 ← collect like terms

   = x^{4} + 3x³ - 3x - 1
