Which function represents a reflection of f(x) = Three-sevenths(2)x over the x-axis?

<u>Given:</u>

The given function is f(x)=\frac{3}{7}(2)^{x}

We need to determine the reflection of f(x) over the x - axis

<u>Reflection over x - axis:</u>

The translation rule to reflect over the x - axis is given by

(x, y) \rightarrow(x,-y)

Reflecting the function over the x - axis, we get;

-y=\frac{3}{7}(2)^{x}

Multiplying -1 to both sides of the equation, we have;

y=-\frac{3}{7}(2)^{x}

This can be written as

g(x)=-\frac{3}{7}(2)^{x}

Hence, the reflection of the function over the x - axis is g(x)=-\frac{3}{7}(2)^{x}

Thus, Option A is the correct answer.

Story : A Dog’s Tale by Mark Twain

4. Read this sentence from the selection.

“Whenever she heard a large word she said it over to herself many times, and so was able to keep it until there was a dogmatic gathering in the neighborhood.”

In this sentence the word dogmatic is used as —

• an insightful simile
• 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 —

• is well educated
• is a dog
• 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.”

• She did not know any synonyms for the word.


9. Which type of person is most like the author’s mother?

• A high-performing student with an excellent memory for words

• A very verbal person who always has a quick answer that sounds good

• A dishonest person who tells lies on a regular basis

• A person who likes dogs a lot and works at a veterinary clinic

How much will it cost to pour a circular slab 18 ft in diameter by 3 in. For a patio if the concrete costs $40.00 per cubic yard
sasho [114]
A circular concrete slab is a cylinder. Vol = pi%2Ar%5E2%2Ah
in this cylinder:
r = 18%2F2 = 9 ft
h = 3%2F12 = .25 ft
:


Find the volume in cu/ft:
V = pi%2A9%5E2%2A.25
V = 63.61725 cu/ft
:
Change to cubic yds; (1 cu/yd = 27 cu/ft) and multiply by $40:
Cost = 63.61725%2F27 * 40
Cost = $94.25


In practical terms , they may require you to buy 3 cu/yds , which is $120

The measure of an angle is five times the measure of its complementary angle. What is the measure of each angle?
GalinKa [24]

Answer:

150 degrees

Step-by-step explanation:

  1. Let the supplement = x  
  2. So the angle you want is 5x  
  3. Then [x + 5x] = 180 because they are supplementary.  
  4. Solving. 6x = 180. Then x = 30.  
  5. So the angle is 5x = 5×30 = 150 degrees
