One is the additive identity. True or False

Answer:

Step-by-step explanation:

Given the ratio of fiction to nonfiction books in a classroom library is 2 to 3, then the total ratio of both books will be 2+3 = 5. If there are 24 books non fiction books in the library, to get the amount of fictionbooks that are there we will follow the following steps.

First we will calculate the total number of books in the shelf;

3/5 * Total number of books = total non fiction books

3/5 * Total number of books = 24

3*Total number of books = 5*24

3*Total number of books = 120

Total number of books = 120/3

Total number of books = 40

Therefore there are 40 total of books on the shelf.

Total number of fiction books = 2/5 * 40

Total number of fiction books = 2* 8

Total number of fiction books = 16 books

Hence there are 16 fiction books on the shelf.

Answer:

y = 3

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

We know that a horizontal line has a slope of zero:

Slope m = 0

y = 0x + b

y = b

Since we are trying to find a line that fits with (-1, 3), we look solely at the y-value.

y = 3

We want to find the equation of a horizontal line such that it passes through a given point.

The answer is: y = 3

We know that the general form of a horizontal line is:

y = a

Where a is a real number.

Now, we also want that our line passes through the point (-1, 3).

Notice that the y-value of the point is 3, and in a horizontal line we can have only one value of y, so the horizontal line must be:

y = 3

The graph of the line and the point can be seen below

Complete Question  

Find the average value of the function over the given interval. (Round your answer to three decimal places.) f(x) = 12e^x, [−6, 6] Find all values of x in the interval for which the function equals its average value. (Enter your answers as a comma-separated list. Round your answers to three decimal places.)

Answer:

The  average is  

  [tex]AV  =  403[/tex]

The value of  x is

Step-by-step explanation:

From the question we are told that

  The equation is  [tex]f(t) =  12e^x[/tex]

  The  points consider is  [-6 , 6]

Generally the average value of the function over the given interval is mathematically represented as

          [tex]AV  =  \frac{1}{z-w} \int\limits^ z_w {f(x)} \, dx[/tex]

          [tex]AV  =  \frac{1}{ 6 - (-6)}  \int\limits^{6}_{-6} { 12e^x} \, dx[/tex]

          [tex]AV  =  \frac{1}{12 } e^x| \left 6} \atop {-6}} \right.[/tex]

          [tex]AV  = e^6 -e^{-6}[/tex]

Generally when the function equal the average we have that

Answer:  B. g(x) = –4(x – 3)2

Step-by-step explanation: To apply the changes to the equation of a vertical stretch of 4 and a translation of 3 units to the right, as well as the correct answer would be choice B.

The reason for this is when you apply a vertical stretch, because it changes the y-values (which causes it to vertically stretch or appear skinnier when graphed), you would multiply 4 to f(x) which would look like 4x^2.

Then, since you have a reflection over the x-axis, you must multiply a -1 to f(x) to reflect it over the x-axis which would result in -4x^2.

Finally, it also asks to shift the graph right 3 which by moving it right, you change the x values meaning you will perform f(x-3) to achieve this (subtract the value from x when you move right, and add the value to x when you move left).

Answer: (6^-8/7^-12)

Step-by-step explanation:

In this type of problems, you apply the laws of indices which stated that

( a²/b²)³ =( a²×³/b²×³)

= ( a6/b6)

From this question now, applying the above principle

(6²/7³)-4

= (6²×-⁴/7³×-⁴)

= (6^-8/7^-12)

So the answer is C

f(x) = 3x – 2, g(x) = 7 – x2.

3f(1) - 49(-2)

Substitute the given value into the function and evaluate.

101

The value of 3f(1) - 49(-2) for the given function f(x) = 3x – 2 will be 101.

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

Given the function,

f(x) = 3x – 2

Now,

f(1) = 3(1) - 2 = 1

So,

3f(1) - 49(-2) = 3×1 - 49(-2)

⇒ 3 + 98 = 101

Hence "The value of 3f(1) - 49(-2) for the given function f(x) = 3x – 2 will be 101".

Part A

1 hour = 60 minutes

0.5 hours = 30 minutes (multiply both sides by 0.5)

11.5 hours = 11 hours + 0.5 hours

11.5 hours = 11 hours + 30 minutes

11.5 hours = 11 hours, 30 minutes is the answer

========================================

Part B

20% = 20/100 = 0.20

The lion sleeps 20% more than the cat, which means the lion sleeps 0.20*11.5 = 2.3 hours more

This leads to 11.5 + 2.3 = 13.8 hours being the total time the lion sleeps

1 hour = 60 minutes

0.8 hours = 48 minutes (multiply both sides by 0.8)

13.8 hours = 13 hours + 0.8 hours

13.8 hours = 13 hours + 48 minutes

13.8 hours = 13 hours, 48 minutes is the amount of time the lion sleeps

Answer:

2/5 is greater

Step-by-step explanation:

to compare you need to make them common denominator, and that could be10. to make both denominators equal to ten just multiply the top and bottom of 2/5 by 2. this will turn it into 4/10. 4/10 is greater than 3/10

The solution is : 2/5> 3/10

2/5 is greater than 3/10

A fraction represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters.

Here, we have,

the given fractions are,

2/5 and 3/10

now, we have,

to compare you need to make them common denominator,

and that could be10.

to make both denominators equal to ten just multiply the top and bottom of 2/5 by 2.

i.e. 2*2/5*2

=4/10

this will turn it into 4/10.

now, we get,

4/10 is greater than 3/10

Hence, 2/5> 3/10 , 2/5 is greater than 3/10.
