what is 2 less than the square of a number ASAP

Answer:

Arithmetic sequence:  \(a_{n}=a_{1}+(n-1)d\)

Geometric sequence: \(a_{n}=a_{1}(r)^{n-1}\)

Step-by-step explanation:

The arithmetic sequence: is the sequence whos terms increased or decreased by a constant amount.

Examples:

The explicit formula for the nth term of the arithmetic sequence is:

The geometric sequence: is the sequence whos consecutive terms have a constant ratio

Examples:

The explicit formula for the nth term of the geometric sequence is:

* Arithmetic sequence          →→→→→→   Geometric sequence

 Has a constant difference    →→→→→→    Has a constant ratio

 \(a_{n}=a_{1}+(n-1)d\)                  →→→→→→    \(a_{n}=a_{1}(r)^{n-1}\)

 \(d=a_{n}-a_{n-1}\)                          →→→→→→    \(r=\frac{a_{n}}{a_{n-1} }\)

The correct symbol to use between the quantities A and B is the union symbol (∪). Therefore, the correct choice is:

c. AB = {0, 1, 2, 3, 4, 8}

The union of two sets, denoted by the symbol (∪), represents the combination of all elements from both sets without repetition. In this case, A = {0, 1, 2, 3} and B = {1, 2, 4, 8}. When we take the union of these two sets, we combine all the elements from A and B, resulting in the set AB = {0, 1, 2, 3, 4, 8}. Therefore, the correct choice is c, AB = {0, 1, 2, 3, 4, 8}.

To understand the concept of set union, it is essential to consider the individual elements in sets A and B. Set A contains the elements {0, 1, 2, 3}, and set B contains the elements {1, 2, 4, 8}. When we take the union of these sets, we combine all the elements without duplication.

In this case, set AB would include all the elements from both sets: {0, 1, 2, 3} from set A, and {1, 2, 4, 8} from set B. However, since 1 and 2 appear in both sets, we only include them once in the union. Thus, the final union set AB is {0, 1, 2, 3, 4, 8}.

It's important to note that the order of elements in a set doesn't matter, and duplicate elements are removed when taking the union. The union operation allows us to combine multiple sets into a single set, containing all the unique elements from each set.

The statement that best shows active listening is "The listener focuses on the speaker, remains undistracted, and may ask clarifying questions.". So, correct option is A.

Active listening is an important communication skill that involves paying full attention to what the speaker is saying, both verbally and non-verbally. Active listening requires the listener to be fully engaged in the conversation, understand the speaker's perspective, and respond appropriately.

Option A) best shows active listening because it includes key aspects of this skill. Focusing on the speaker and remaining undistracted shows that the listener is fully engaged in the conversation, while asking clarifying questions demonstrates an effort to understand the speaker's message.

On the other hand, Option B) is not an example of active listening as it suggests the listener is not fully engaged in the conversation. Option C) may be helpful for taking notes, but does not necessarily demonstrate active listening, as the listener may miss non-verbal cues or tone of voice.

Option D) can be seen as interrupting the speaker and not allowing them to fully express their thoughts, which can hinder effective communication.

Equilibrium is the term refers to coordination, balance, and balance in three dimensional space.

The equilibrium condition of an object exists when Newton's first law is valid. An object is in equilibrium in a reference coordinate system when all external forces (including moments) acting on it are balanced. This means that the net result of all the external forces and moments acting on this object is zero.

There are three types of equilibrium: stable, unstable, and neutral.

a) 58^-8 is the same as 1/58^8. we can also simplify the expression by applying the rule for negative exponents to the entire fraction.

To evaluate this expression, we can use the rule that any number raised to a negative exponent is equal to the reciprocal of the same number raised to the same positive exponent. In other words, x^-n = 1/x^n.

Applying this rule to the expression 1/58^8, we get:

1/58^8 = 1/(58^8) = 58^-8

Therefore, the correct answer is 58^-8.

It is important to note that the exponentiation operator (^) has higher precedence than the division operator (/), so we need to use parentheses to indicate that the exponent should be applied to the entire denominator before the division is performed. In this case, we can also simplify the expression by applying the rule for negative exponents to the entire fraction:

1/58^8 = (1/58)^8 = 58^-8

This simplification shows that the correct answer is still 58^-8.

From the computation done, it can be denoted that the total price that will be paid will be $12.90.

1 Krispy Kosmos at $2.89 = $2.89

2 Chewy Chocos at $3.19 each = 2 × $3.19 = $6.38

1 Gooey Globs at $2.99 = $2.99

Total = $2.89 + $6.38 + $2.99 = $12.26

We'll then add the sales tax of 5.2%, therefore, the total value will be:

= $12.26 + (5.2% × $12.26)

The given equation is dydx=x2x and we have to solve the equation when y(4)=19. To solve this equation, we will use the integral of the given equation.

The integral of the equation is y=x3/3 + C, where C is a constant.
We know that y(4)=19, so we can plug in 4 for x and 19 for y to solve for C.
Therefore, C = 19 - (43/3) = 23/3.

So, the solution to the equation is y=x3/3 + 23/3.

To set up an integral for solving dy/dx = x^2 when y(4) = 19, we need to use the Fundamental Theorem of Calculus. This theorem states that if F(x) is an antiderivative of f(x), then the integral of f(x) from a to b is F(b) - F(a).

First, we need to find the antiderivative of x^2. The antiderivative of x^2 is (x^3)/3 + C, where C is a constant.

Step-by-step explanation:

g(x)=x^-4

g(-3)= -3^2-4 = 9-4 = 5

g(-2)= -2^2-4 = 4-4 = 0

g(-1)= -1^2-4 = 1-4 = -3

g(0)= 0^2-4 = 0-4 = -4

g(1)= 1^2-4 = 1-4 = -3

g(2)= 2^2-4 = 4-4 = 0

g(3)= 3^2-4 = 9-4 = 5

The total surface area is 1308 meters square

From the question, we have the following dimensions

Length = 19 m

Width = 16 m

Height = 10 m

The total surface area is then calculated as:

Total surface area = 2 * (Length * Width + Width * Height + Length * Height)

Substitute the known values in the above equation

Total surface area = 2 * (19 * 16 + 16 * 10 + 19 * 10)

Evaluate the expression

Total surface area = 1308

Hence, the total surface area is 1308 meters square

Using the probability, the expected number of female children in a family with three children is 1.5. The option 2 is correct.

In the given question, we have to find the expected number of female children in a family with three children.

The possibility of having girls in family is 0,1,2 or 3.

From the 8 possible sequences, only one of them give the possibility of 0 girls.

So the probability of 0 girls is 1/8.

There are total 3 ways of having 1 girl.

That is: GBB, BGB, and BBG.

Thus, the probability of 1 girl is 3/8.

Similarly checking for having 2 girls with probability 3/8

Having 3 girls with probability 1/8.

The predicted number of girls is calculated as a weighted average of all potential numbers, where a number's weight is determined by its likelihood of occurring.

The anticipated number of girls is therefore

= 1/8⋅0+3/8⋅1+3/8⋅2+1/8⋅3

= 0+3/8+6/8+3/8

=(3+6+3)/8

=12/8

=1.5

Hence, the expected number of female children in a family with three children is 1.5.

The class size is 10.

The upper limit of the class interval 40 - 50 is 50/

The lower limit of the class interval 20 - 30 is 20.

The frequency of class interval 10 - 20 is 10.

A class interval is a group of values that are put together for computation in a frequency distribution. An example of a class interval is 20 - 30. The class size is the difference between the upper limit and the lower limit of a class interval. The class size is the same for all the data set.

Class size = upper limit - lower limit

50 - 40 = 10

The upper limit is the biggest number in a class. The lower limit is the smallest number in a class. For example in the class 20 - 30, the  upper limit is 30 and the  lower limit is 20.

25463 grams radioactive kind of americium will be left after 2160 years.

We know that Half Life Formula will be,

\(N=I(\frac{1}{2})^{\frac{t}{T}}\)

where N is the quantity left after time 't'; 'T' is the half life of the substance and 'I' is the initial quantity of the substance.

Given that the initial quantity of the substance (I) = 814816 grams

Half life of the radioactive kind of americium is (T) = 432 years

The time elapsed (t) = 2160 years

Now we have to find the quantity left that is the value of N for the given values.

N = \(814816\times(\frac{1}{2})^{\frac{2160}{432}}=814816\times(\frac{1}{2})^5\) = 814816/32 = 25463 grams.
