An example of 17.3 subtracting polynomial expressions question is solve for 2q² - q - 8) - (2 q² + q - 4).

A polynomial is known to be a type of  an expression that is made up of variables, constants and exponents. They are often combined using the mathematical terms such as addition, subtraction, etc.

2 q² - q - 8) - (2 q² + q - 4)

= (2 q² - q - 8) + (-2 q² - q + 4)

Then you have to rewrite subtraction as addition and then Group like terms together;

= (2 q² - 2 q²) + (-q - q) + (-8 + 4)

= -2q - 4

The angle generated by the hour hand measures -270° or -4.71 radians, and we will see that the angle generated by the minute hand is 12 times the one generated by the hour hand.

Remember that in a complete rotation we have an angle of 360°, and in a complete rotation we have 12 hours, then there is a relation:

12 hours = 360°

1 hour = 360°/12 = 30°

From 9:00 a.m to 5:00 p.m. there are 9 hours, so the angle that the hour hand does is:

A = 9*(30°) = -270°

(the negative sign is because this angle is measured clockwise)

Now we can write this in radians, remember that:

3.14 radians = 180°

Then:

1 = (3.14 rad/180°)

Then:

270° = -270°*(3.14 rad/180°) = -4.71 rad

Each hour that passes, the minute hand does a complete revolution. Then in 9 hours, the minute hand does an angle of:

A = 9*(-360°) = -3,240°

To compare this angle to the one generated by the minute hand we take the quotient:

-3,240°/-270° = 12

So this angle generated by the minute hand is 12 times the one generated by the hour hand.

Through the use of a light microscope it is possible to observe in multicellular organisms different types of cells and organelle features, and in general, they are all very small.

They are all those forms of life whose bodies are composed of a diversity of cells organized, hierarchical, at the cellular level through organelles that are specialized cell differentiations.

The cells that make up these organisms have different shapes and sizes and, in general, they are all very small, so to see them it's needed a light microscope, an instrument that increases many times the size of samples.

Therefore, we can conclude that through the use of a light microscope it is possible to observe in multicellular organisms different types of cells and organelle features, and in general, they are all very small.

Taking into account the definition of permutation, there are 1320 ways you can listen to 3 songs from a cd that has 12 selections.

Permutations refer to the action of arranging all the members of a set in some kind of order or sequence. This means that if a set is already ordered, the process of rearranging its elements is called permutation.

In other words, permutations of m elements in n positions are the different ways in which the m elements can be arranged occupying only the n positions.

In this case, the elements are not repeated, since if they are repeated or equal to each other, exchanging them does not generate a new permutation. And the order does matter, since the exchange between two different elements generates a new permutation

To obtain the total of ways in which m elements can be placed in n positions, the expression is used:

[tex]P=\frac{m!}{(m-n)!}[/tex]

The sign ! indicates the factorial function, which indicates that all positive integers between the number that appears in the formula and the number 1 must be multiplied.

The order in which songs are listening is important as there is no plan to listen to the same song twice. So, the permutation can be applied.

Being:

and replacing in the expression for permutation, you get:

[tex]P=\frac{12!}{(12-3)!}[/tex]

[tex]P=\frac{12!}{9!}[/tex]

[tex]P=\frac{479001600}{362880}[/tex]

P= 1320

Since this cylinder has a radius of 2 inch, its volume is equal to 25.12 cubic inches.

Given the following data:

In Mathematics, volume can be defined as a scalar quantity that is used to express the amount of three-dimensional (3D) space that is occupied by an object such as a cylindrical can, or enclosed by a boundary.

Mathematically, the volume of a cylinder is given by this formula:

[tex]V = \pi r^2h[/tex]

Where:

Substituting the given parameters into the formula, we have;

[tex]V = 3.14 \times 2^2 \times 2\\\\V=3.14 \times 4\times 2\\\\V=6.28 \times 4[/tex]

"Reusing, reducing, or recycling" could decrease the amount of fossil fuels used as it lowers global warming/litter.

Reduce is referred to the lowering use of the substance, resources, or any other items. Reuse refers to the repeated benefit or a resource, item, or any substance.Recycling is the process of collecting and processing the materials again to avoid it throwing them in the trash.

The 3R's are the reduce, reuse, and recycle the waste or products. Reduce is referred to diminish the use of certain products or resources, reuse is to repeated use of items, and recycle is to mold and develop into a new item.

Throwing antifreeze can become ilegal because it gets heavy metals such as lead, cadmium and chromium that make it hazardous waste, which should not be thrown in public areas.
