The value of the given factorial expression is 10! - 6! will be 3,628,800.

The factor of n is given as the production of the number n, (n - 1), (n - 2)... and 1. Then the factorial of n is given as

n! = n x (n - 1) x (n - 2) x ... 3 x 2 x 1

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expression is given below.

⇒ 10! - 6!

Simplify the expression, then we have

⇒ 10! - 6!

⇒ 10 x 9 x 8 x 7 x 6! - 6!

⇒ 6! (10 x 9 x 8 x 7 - 1 )

⇒ 6 x 5 x 4 x 3 x 2 x 1 x (5040 - 1 )

⇒ 6 x 5 x 4 x 3 x 2 x 1 x 5039

⇒ 3,628,800

One water tank can be rented for 160 dollars, according to the provided statement.

The radius of a circular is the separation between its centre and perimeter. Always, the circumference is twice the radius.

The volume of the cylinder-shaped water tank is given by the formula

V = πr²h, where

r is the radius

h is the height.

Substituting the given values, we get:

V = π(4 feet)²(2 feet) = 32π cubic feet

The cost of renting the water tank is given by the product of the volume and the cost per cubic foot:

Cost = 5 dollars/cubic foot × 32π cubic feet

Multiplying these values, we get:

Cost = 160π dollars

Therefore, it costs 160π dollars to rent one water tank.

In linear equation, the store will get $468.72 from the sale of the couch.

What in mathematics is a linear equation?

An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.

                          Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

a.

Commission can be referred to as the reward given by the company on goods for the employee to sell products in order to make more sales and more money.

Commission is calculated as follows:

Total commission = Total Sales * Commission Percentage

Given

Total Sales = $495

Commission Percentage = 5½%

Substitute in, the above values

Total Commission = $496 * 5½%

Total Commission = $496 * 5.5%

Total Commission = $496 * 0.055

Total Commission = $27.28

Hence, the total commission is calculated as $27.28

b. The amount remitted to the store is calculated as

Amount = Total Sales - Total Commission

Where Total Sales = $496

Total Commission = $27.28

Amount = $496 - $27.28

Amount = $468.72

Hence, the store will get $468.72 from the sale of the couch.

By applying a rotation of 180° to the ordered pairs of points X and Y, the coordinates of its image (X′Y′) can be calculated as follows:

Step-by-step explanation:

To answer this question, we need to find the expected number of students who will vote 9 years from now. To do this, we will apply the 10% decrease in voting every year.

Starting with 341 students who voted this year, we decrease the number of voters by 10% every year.

After 9 years, the number of voters would be:

341 * (1 - 0.10)^9 = 341 * 0.354813389233575594 = 121.05

So, it is expected that 121 students will vote 9 years from now. Rounding to the nearest whole number, we get 121.

Therefore, the answer is 121 students.

Therefore, the area of the square is A = s^2, where s is the length of one side.

Step 2: Find the length of one side of the garden.

The given area is A = 52 square feet.

Substituting this value into the equation for the area of a square, we get 52 = s^2.

Step 3: Solve for s.

To solve for s, we can take the square root of both sides of the equation.

This gives us s = √52 ≈ 7.21 feet.

differently than they would in a natural habitat.  

                                         and

D. The presence of the researchers may affect the lions' behavior.

Step-by-step explanation:  Studying lion behavior in zoos has limitations. The artificial environment of a zoo can affect how lions behave compared to their behavior in the wild.  Additionally, the presence of researchers may influence the lions' behavior, making it difficult to observe and understand their natural interactions.

B. The environment of the zoo may cause the lions to behave differently than they would in a natural habitat.

In a zoo, lions are confined to a limited space and are provided with a controlled environment.  This artificial setting may not accurately reflect their natural habitat and can influence their behavior.  For example, the availability of food, different social dynamics, and reduced hunting opportunities in a zoo can lead to altered behaviors that may not be representative of how lions behave in the wild.

D. The presence of the researchers may affect the lions' behavior.

When researchers observe animals in a zoo, their presence can influence the behavior of the lions.  The presence of unfamiliar humans can cause the animals to become more cautious, stressed, or exhibit abnormal behavior.  This could potentially alter the social interactions and dynamics observed by the researchers, making it challenging to accurately understand and interpret natural lion behavior.

There are 30 dogs in the store, and 12 cats.

Let's call the number of dogs in the store "x".

Expanding and solving for x:

2x - 18 = 42

2x = 60

What is an exponent?

The way of representing huge numbers in terms of powers is known as an exponent. Exponent, then, is the number of times a number has been multiplied by itself.

The integer 75 is written as -

[tex]2^0+2^1+2^2+2^6[/tex]

75 is expressed as sum of the powers of 2, with whole number exponents.

To find 75 expressed as sum of the powers of 8, divide the integer by 8 -

[tex]8^0=1[/tex]

[tex]8^1=8[/tex]

[tex]8^2=64[/tex]

Only one integer 2 is left to complete the sum as 75.

= (1/2x)(5x^2) + (1/2x)(-2x) + (1/2x)(6) - (1/4)(5x^2) + (1/4)(2x) - (1/4)(6)

= (5/2)x^2 - x + 3 - (5/4)x + (1/2)x - (3/2)

(b) No, the product of 1/2x-1/4 and 5x^2-2x+6 is not equal to the product of 1/4x-1/2 and 5x^2-2x+6. This is because when we expand both products using the distributive property, we get different expressions:

(1/2x - 1/4)(5x^2 - 2x + 6) = (5/2)x^2 - (3/4)x + 3/2

(1/4x - 1/2)(5x^2 - 2x + 6) = (5/4)x^2 - (7/4)x + 3
