Which answer choice shows that the set of irrational numbers is not closed under addition

Since you didn't give the choices, I can only help with the problem. Then, you can select the correct answer.

A set is closed under a given operation, if all possible values in the set would produce the same type of number when the operation is completed.

For example: 
The square root of 5 plus the square root of 5 is two square roots of 5.
Both of numbers are irrational and they produce an irrational result.

Here is one example, like you should be looking for.
Irrational numbers are not closed under addition because:
Pi plus a negative pi would be zero. 
Pi and negative pi are irrational however zero is not irrational.
Therefore, the set is not closed.

An object has the mass of 900 g and a volume of 1,875 cm3.
romanna [79]

If the mass of the object is 900 g and the volume is 1,875 cm³. Then the density of the object is 0.48 g/cm³.

<h3>What is density?</h3>

Density is defined as the mass per unit volume. It is an important parameter in order to understand the fluid and its properties. Its unit is kg/m³.

The mass and density relation is given as

Density = mass / volume

An object has a mass of 900 g and a volume of 1,875 cm³.

Then the density will be

Density = 900/1875

Density = 0.48 g/cm³

Then the density of the object is 0.48 g/cm³.

To learn more about the density refer to the link;

How do I do this please help??
Brums [2.3K]

Answer:

Slope: 4

Y-intercept: -5

Equation: y=4x-5

Step-by-step explanation:

Slope formula:

\frac{y2 - y1}{x2 - x1}

So let's use the ordered pairs (1, -1) and (2,3) from the table (it doesnt matter which ones you choose) and plug the numbers in to the formula:

\frac{3 - ( - 1)}{2 - 1}

Which is equal to:

\frac{4}{1}

Which is equal to 4. So the slope is 4.

To find the y-intercept, substitute the slope and an ordered pair into the slope-intercept equation, y=mx+b. So let's use (1,-1).

-1=4(1)+b

= -1=4+b

= -1-4=4-4+b

= -5=b

So the y-intercept is -5.

Then for the equation, you just plug in the slope and the y-intercept into y=mx+b, which would be:

y=4x-5

What is the fourth term of the expansion of the binomial (2x+5)^5?
Crank

Answer:

B) 5000x^2

Step-by-step explanation:

The exponent of x starts at 5 in the first term and decreases by 1 as the term numbers increase by 1. Hence, the 4th term will have 2 as the exponent of x. (It will have 5-2=3 as the exponent of 5.)

Pascal's triangle tells you the coefficients of the 6 terms in the expansion will be 1, 5, 10, 10, 5, 1, so the 4th term has a coefficient of 10.

The 4th term will be ...

10(2x)^2(5)^3 = 10·4·125·x^2 = 5000x^2
