The sum of a number and it's absolute value is negative.

Answers

Answer:

False; the scenario is not possible.

Step-by-step explanation:

This scenario is not possible. I will demonstrate it by representing a number by [tex]x[/tex]. There are two possibilities: [tex]x[/tex] and [tex]-x[/tex]. Let's try both:

[tex]x + |x|[/tex]

[tex]x + x[/tex]

[tex]2x[/tex]

The sum for positive [tex]x[/tex] and its absolute value is not negative. Let's try with the negative value of [tex]x[/tex] now:

[tex]-x +|-x|[/tex]

[tex]-x + x[/tex]

[tex]0[/tex]

The sum for negative [tex]x[/tex] and its absolute value is not negative either, it is zero which is neither negative or positive. Therefor, we can safely say that the scenario described is not possible.

Answer:  The guage block height is 4.98 m

The base of the right triangle that is formed is 7.3784 m

The last angle in the triangle is 56 degrees

Step-by-step explanation:

Redraw the triangle formed in the picture and use H for the hypotenuse, O for the block height, and A for the base.  Now we can use trig (SOHCAHTOA) to find the answaers.

Using sine, we can first find the gauge block height, O (Opposite).  Given the Hypotenuse (H) is 8.9 m, we can use the definition of the sine of an angle to find the height, O.

Sine(34) = Opposite/Hypotenuse (O/H), or O = H*Sine(34)

O = (8.9)*(0.5592)

O = 4.98 m, the height of the gauge block,

The base of the triangle, A, can be determined with cosine.

Cosine(34) = A/O, or A = Cosine(34)*O

A = (0.82904)*(8.9)

A = 7.3784 m

The sum of all angles in a triangle is 180 degrees.  

180 = X + 34 + 90

X = 56 degrees

D. -3 because it is the negative number with the greatest absolute value. 22 hen click Check Answer​

Answers

Answer:  Choice A.

- 4.5 because it is the negative number with the greatest absolute value.

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

Explanation:

Stuff to the left is smaller than stuff on the right for any number line.

For example, we can say 2 < 5 since 2 is to the left of 5.

Another example: -7 < 4

To find the smallest item of your given list, we need to look at the value that is furthest to the left. That value would be -4.5 and this value is negative with the largest absolute value (i.e. it is furthest away from 0).

Check out the number line diagram below. It shows where all of the values are placed. We can see that -4.5 is the left-most item.

Step-by-step explanation:

I don’t get this how do these things work please explain

Answers

Answer:

Ok, so:

-The number of people who like tea are represented in the first column.

-The number of people who dislike tea are represented in the second column.

-The number of people who like coffee are represented in the first row.  

-The number of people who dislike coffee are represented in the second row.

This works like a multiplication chart:

People who like tea and coffee are represented in the top left square. People who dislike tea and coffee are represented in the box that coordinates to T' and C' (If you find T' and C' and run your fingers along the column/row until they run into each other, you'll find it.) The same is true for other combinations.

At the bottom of the first column is the total number of people who like tea. At the right-most part of the first row, is the total number of people who like coffee.

(52 people like tea, 80 people were surveyed)

I hope this helps you understand, please ask any clarifying questions you need! : )

HELP DETERMINE THE RANGE OF THE FOLLOWING GRAPH … I WILL MARK BRAINLIEST

Answers

While the domain is how far left-to-right the graph goes (it’s about the x-values),

the range is about how low to how high the graph gets. The range is about the y-values used in the graph.

Your graph bottoms out at -6 and tops out at 4, but never gets to 4, because of that open circle.

So the range is -6 ≤ y < 4. Note that we use y for the range.

Interval: [-6,4)
Set-builder: { y | -6 ≤ y ≤ 4 }
Again, be sure to use y in the set-builder.
