Let f(x)=x²-x-12 and g(x)= x -4.
What value can the expression (f/g)(x) never equal?

Answers

Answer 1

Answer:

7

Step-by-step explanation:

This function can never equal 0. Why? well here:

(f/g)(x) also just means [tex]\frac{f(x)}{g(x)}[/tex]. In this case, we get [tex]\frac{x^2-x-12}{x-4}[/tex] Or [tex]\frac{(x+3)(x-4)}{x-4}[/tex]. It seems like you can cancel out x-4 and bam, you get x+3 and any value should work.

However, x can never equal 4 because 4 leads to a case where you divide by 0. This is called discontinuity. Thus, the value you can't get is x=4, or 7 because when you plug 4 in, you get 0/0. Otherwise, any other real value is defined by x+3.

Step-by-step explanation:

1). [tex]8\frac{1}{4}[/tex] ÷ [tex]\frac{3}{4}[/tex]

= [tex]\frac{33}{4}[/tex] ÷ [tex]\frac{3}{4}[/tex]

= [tex]\frac{33}{4}\times \frac{4}{3}[/tex]

= 11

2). [tex]3\frac{1}{3}[/tex] ÷ [tex]\frac{10}{3}[/tex]

= [tex]\frac{10}{3}[/tex] ÷ [tex]\frac{10}{3}[/tex]

= [tex]\frac{10}{3}\times \frac{3}{10}[/tex]

= 1

3). [tex]\frac{5}{4}[/tex] ÷ [tex]\frac{1}{4}[/tex]

= [tex]\frac{5}{4}\times \frac{4}{1}[/tex]

= 5

4). [tex]\frac{25}{4}[/tex] ÷ [tex]6\frac{1}{4}[/tex]

= [tex]\frac{25}{4}[/tex] ÷ [tex]\frac{25}{4}[/tex]

= [tex]\frac{25}{4}\times \frac{4}{25}[/tex]

= 1

5). [tex]11\frac{1}{4}[/tex] ÷ [tex]\frac{9}{4}[/tex]

= [tex]\frac{45}{4}[/tex] ÷ [tex]\frac{9}{4}[/tex]

= [tex]\frac{45}{4}\times \frac{4}{9}[/tex]

= 5

6). [tex]3\frac{1}{7}[/tex] ÷ [tex]\frac{2}{7}[/tex]

= [tex]\frac{22}{7}[/tex] ÷ [tex]\frac{2}{7}[/tex]

= [tex]\frac{22}{7}\times \frac{7}{2}[/tex]

= 11

Now we can classify the expressions by their quotients as 1, 5 and 11.

A journalist is assigned to write a story that is 1,200 words long. To fit in the publications available space, the story's length can vary by no more than 75 words.

which word counts would be accepted by the journalist's publication?

1,100 1,125 1,290 1,260 1,300​

Answers

So if it can vary by 75 or less, the least it can be is 1,125 and the greatest it can be is 1275.
Therefore it must be between or equal to these two.

The answers are:
1,125
And
1,260

The word count that can be accepted by the journalist's publication is  1,260.

Given,

A journalist is assigned to write a story that is 1,200 words long.

To fit in the publication's available space, the story's length can vary by no more than 75 words.

We need to find which word counts would be accepted by the journalist's publication.

1,100, 1,125, 1,290, 1,260, 1,300​

Find the number of words the publication accepts.

We have,

1,200 words long.

The story's length can vary by no more than 75 words.

So,

1,200 + 75 = 1,275 words

The words can vary from 1,200 to 1,275 words.

Find the option which can be accepted.

1,100 - can not be accepted

1,125 - can not be accepted

1,290 - can not be accepted

1,260 - can be accepted

1,300​ - can not be accepted

Thus the word count that can be accepted by the journalist's publication is  1,260.

The scale on the map is 1 centimeter is equal to 25 kilometers. On the map, the distance the towns along the highway is 4.5 centimeters. Tori's car uses 0.123 liter of gasoline for each kilometer of highway driving. How many liters of gasoline to the nearest liter will Tori need to drive from one of these town to the other?

Answers

Answer: About 14 liters of gasoline is required.

Step-by-step explanation:

On the map,

1 centimeter= 25 kilometers.

Distance the towns along the highway is 4.5 centimeters.

Actual distance = 4.5 x 25 km

= 112.5 km

Tori's car uses 0.123 liter of gasoline for each kilometer of highway driving.

Total gasoline required = 0.123  x  112.5 km

= 13.8375 liters≈ 14 liters

hence, about 14 liters of gasoline is required.
