Answer:

\(\frac{x-1}{x+2}\)

Step-by-step explanation:

simplifying the equation:  \(x^2-3x+2/x^2-1\)

1) Rewrite the equation so it's easier to understand:

\(\frac{x^2-3x+2}{x^2-4}\)

2) factor \(x^2-3x+2\):

\(x^2-3x+2\) \(=> (x-1)(x-2)\)

3) factor \(x^2-4\):

\(x^2-4 => (x+2)(x-2)\)

Meaning: \(\frac{(x-1)(x-2)}{(x+2)(x-2)}\)

4) Cancel the common factor: \((x-2)\) from the numerator and the denominator:

\(=\frac{x-1}{x+2}\)

The cost described in the scenario is an example of a mixed cost.

A mixed cost consists of both fixed and variable components. In this case, the $10 per month base charge represents the fixed component of the cost. This charge remains constant regardless of the amount of electricity consumed. It covers the basic service and is not influenced by usage levels.

On the other hand, the additional charge of $0.08 per kilowatt-hour (kWh) of electricity used represents the variable component. This charge varies directly with the amount of electricity consumed. As more electricity is used, the variable cost increases proportionally.

By combining the fixed base charge and the variable charge per kWh, we get a mixed cost structure. The fixed component ensures a minimum cost for the service, while the variable component adds to the total cost based on actual usage. This combination of fixed and variable elements makes the cost a mixed cost.

Answer:

Nick is 6

Andrea is 18

Step-by-step explanation:

Sounds like a system of equations

Letting...

a = Andrea

n = Nick

Since she's 3 times the age, the first equation will be

a = 3n

Since in 10 years, Andrea will be 12 years older than Nick, we can write

a = n + 12

Since we have two a = ,we can set them equal to each other

3n = n + 12

Subtracting n

3n - n = 12

Now combining the n's (n is the same as 1n)

2n = 12

And last but not least, we can divide by 2

n = 6... so Nick is 6 right now.

Going back to our first equation of a = 3n, if we plug 6 in

a = 6(3) = 18.

Making Andrea 18 right now

Using the binomial distribution, it is found that there is a 0.3125 = 31.25% probability of getting 2 goals out of 5.

The formula is:

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

The parameters are:

The values of the parameters are given as follows:

n = 5, x = 2, p = 0.5.

Hence the probability is:

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 2) = C_{5,2}.(0.5)^{2}.(0.5)^{3} = 0.3125\)

0.3125 = 31.25% probability of getting 2 goals out of 5.

Two parents are present in 69% of all families with children ages six to eleven. Option d is correct.

Option d is the correct choice, which states that 69 percent of all families with children aged six to 11 have two parents. This information is supported by various studies and statistics, which have consistently shown that the majority of families in the United States consist of two-parent households. While single-parent families do exist, they are less common than families with two parents.

This information is important in understanding the dynamics and structure of families in the US, as well as in developing policies and programs that support and strengthen families.

Answer:

ur english is so bad i can barely discern what ur trying to say and the correct answer is 5

Step-by-step explanation:

The equation of the line is y= 5x + 5.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

A line intersects the x-axis at (-1, 0).

and, given line is y= -1/5x + 9.

as, the slope of given line is -1/5.

Now, the slope of perpendicular is negative reciprocal.

so, the slope of perpendicular line is 5.

Thus, the equation of line passes thorough (-1, 0).

y = 5x + b

and, 0- -5 + b

b=5

So, the equation of line is

y= 5x + 5.

The surface area of the given figure is 740 m².

The surface area of the given figure is calculated in parts,

Surface area is the measure of the total area that the surface of an object or a solid shape occupies. It is the sum of the areas of all the faces or surfaces of the object. Surface area is usually measured in square units, such as square inches or square meters.

Calculate the surface area of rectangular faces,

Area = 4 ( length x width )

Area = 4 ( 10 x 11 )

Area = 440 m²

Calculate the area of the base,

Area = 10 x 10

Area = 100 m²

Answer:

The answer is (2x-5) (3x-4).

a) The simple interest earned is $810. b) The annual interest rate paid by the credit union is 5.4%. c) It will take about 12.81 years for Mr. Adams' investment to be doubled at the same rate of interest.

a) To find the simple interest earned, we can use the formula:

Simple interest = Principal x Interest rate x Time

Where the principal is $5,000, the time is 3 years, and the total amount received at the end of 3 years is $5,810. We can rearrange the formula to solve for the interest rate:

Simple interest = $5,810 - $5,000 = $810

Interest rate = Simple interest / (Principal x Time)

Interest rate = $810 / ($5,000 x 3)

Interest rate = 0.054 or 5.4%

b) The annual interest rate paid by the credit union is 5.4%.

c) To find the length of time it will take for Mr. Adams' investment to be doubled at the same rate of interest, we can use the formula:

Doubling time = ln(2) / ln(1 + r)

Where r is the interest rate as a decimal. Plugging in the values:

Doubling time = ln(2) / ln(1 + 0.054)

Doubling time ≈ 12.81 years

Therefore, it will take about 12.81 years for Mr. Adams' investment to be doubled at the same rate of interest.

Answer:

Smallest possible x = 98.

Step-by-step explanation:

4312 = 2 * 2 * 2 * 7 * 7 * 11

56 = 2 *2 * 2 * 7

Because the HCF is 14:-

x =   = 2 * 7 OR  2 * 7 * other prime number(s).

As there are 2 7's in the prime factors of 4312 there must also be another 7 in the prime factors of x.

x =  2 * 7 * 7 = 98.

After the teacher moves to a more abstract approach to adding two-digit numbers on day three, the next step in the lesson series could be to introduce regrouping or carrying over when adding two-digit numbers. This would involve teaching students how to add the tens and ones separately and then combining them to get the final answer. The teacher could also provide practice problems and hands-on activities to reinforce this concept.

1. Review the concrete methods previously taught for adding two-digit numbers, such as using base-ten blocks or place value charts.
2. Introduce the abstract method of adding two-digit numbers by stacking the numbers vertically, aligning the ones and tens place, and adding the digits column by column.
3. Demonstrate the process with an example, emphasizing the importance of carrying over when the sum in a column exceeds 9.
4. Provide students with additional practice problems to reinforce the abstract method and check their understanding.
5. Gradually increase the complexity of the problems as students become more comfortable with the abstract approach.

Answer:

254 inches squared

Step-by-step explanation:

Hi there!

\(A=\pi r^2\) where r is the radius of the circle

The radius is equal to half the diameter. Given that the diameter is 18 inches, we know that the radius of the circular plate is 9 inches. Plug this into the equation:

\(A=\pi (9)^2\\A=81\pi \\A=254\)

Therefore, the area of the plate is approximately 254 inches squared.

If this is not an answer choice, the question may have been asking for the radius of the circle rather than the area.

I hope this helps!
