For square a of perimeter 24 cm and square b has an area equal to one-fourth the area of the square a, the perimeter of square b is 12 cm.

Given that a square has a perimeter of 24 cm. And another square b has an area equal to one-fourth of the area of square a. To find the perimeter of square b, we need to find the length of the side of square b using the area of square

Area of the square a = side² of the square a
The perimeter of the square a = 4 × side of the square a

Given that, Perimeter of square a = 24 cm⇒ 4 × side of square a = 24 cm⇒ side of square a = 24 / 4 cm⇒ side of square a = 6 cm.

Area of square b = 1/4 × Area of square a = 1/4 × side² of square a= 1/4 × 6² cm²= 9 cm²

Side of square b = √9 cm = 3 cm
Perimeter of square b = 4 × 3 cm = 12 cm

Therefore, the perimeter of square b is 12 cm.

Answer:

1) \(3x^{2}\)-19x-14

2) x=0, x=3

Step-by-step explanation:

1) (3x+2)(x-7)

Distribute the 3x to both x and -7, as well as the 2 to both x and - 7.

\(3x^{2}\) - 21x + 2x -14

Combine like terms

\(3x^{2}\) - 19x - 14

In order to find the factors of x, set the expression equal to 0.

\(3x^{2}\) - 9x = 0

Factor out the highest common multiple (3x)

3x(x-3) = 0

In order for x to satisfy the equality, you must either have a 0 in the parenthesis -> (x-3)=0 -> x =3

Or 3x = 0 -> x = 0

Answer:

false, because cos(x) has no definite answer, and equations aren't identities

Step-by-step explanation:

The profit function if the cost and revenue is given  P(x) = -0.01x² + 3.2x - 150.

To find the profit function P(x), we subtract the cost function C(x) from the revenue function R(x). This gives us the expression for P(x) as P(x) = R(x) - C(x).

The profit function P(x) represents the difference between the revenue R(x) and the cost C(x). To find P(x), we subtract C(x) from R(x):

P(x) = R(x) - C(x)

Substituting the given expressions for R(x) and C(x), we have:

P(x) = (9x - 0.01x²) - (150 + 5.8x)

Simplifying this expression, we get:

P(x) = 9x - 0.01x² - 150 - 5.8x

Combining like terms, we have:

P(x) = -0.01x² + 3.2x - 150

Thus, the profit function is given by P(x) = -0.01x² + 3.2x - 150. This function represents the profit made as a function of the quantity of goods sold, x. It allows us to analyze the relationship between revenue, cost, and profit for different values of x.

=> CDs loaned out in total: 86 + 16 + 45 + 126 = 273

=> 126 reggae CDs were lent out.

Number of reggae CDs loaned out relative to the total number of CDs loaned out, experimental likelihood of lending a reggae CD

=> A reggae CD's experimental chance of being lent out  = 126/273.

We may calculate the experimental probability's approximation using a calculator as follows:

=> A reggae CD will be lent out with an experimental probability of 0.4615.

So the amount of gain that can be deferred under the installment sale method is $424,879.16.

Percent is a way of expressing a number as a fraction of 100. The word "percent" means "per hundred" in Latin. When a number is expressed as a percentage, it is usually accompanied by the "%" symbol. Percentages are commonly used in many areas of everyday life, such as finance, taxes, and statistics. They are often used to express changes or differences, such as percentage increases or decreases in prices or quantities, or the percentage of people who hold a certain opinion or belong to a certain group.

Here,

To calculate the gain that can be deferred under the installment sale method, we need to first calculate the total gain on the sale. The total gain is equal to the selling price minus the adjusted basis of the property, which is the cost minus the accumulated depreciation.

Selling price = $99,800 cash + $998,000 note = $1,097,800

Adjusted basis = $798,400 - $479,040 = $319,360

Total gain = $1,097,800 - $319,360 = $778,440

To calculate the gain that can be deferred, we need to determine the gross profit percentage. The gross profit percentage is equal to the total gain divided by the selling price:

Gross profit percentage = Total gain / Selling price = $778,440 / $1,097,800 ≈ 0.7097 or 70.97%

Now we can calculate the amount of gain that can be deferred using the formula:

Gain deferred = Gross profit percentage × Payments received

Since the note is due in two years, Skylar will receive half of the payments in 2022 and the other half in 2023. Therefore, the payments received in 2022 are:

$99,800 + ($998,000 / 2) = $598,800

Substituting into the formula, we get:

Gain deferred = 0.7097 × $598,800 = $424,879.16

The area of a rectangle οccupies is the space it takes up inside the limitatiοns οf its fοur sides. The dimensiοns οf a rectangle determine its area. In essence, the area οf a rectangle is equal tο the sum οf its length and breadth.

Let us take side length οf the square = x

Adding 50 feet fοr οne side then , length οf rectangle = x+50 feet.

Nοw decreasing 20 feet fοr οther side then, width οf rectangle = x- 20 feet.

A) Now area of the rectangle is ,

A = length*width

=> A = (x+50)(x-20)

=> A = \(x^2-20x+50x-1000\)

=> A = \(x^2+30x-1000\)

Then , the expression represent the area of the rectangle is \(x^2+30x-1000\) \(ft^2\)

Step-by-step explanation:

Since the question is asking what makes the statement x>1 true, we can determine that 1.2, 4, and 8 all fit because these numbers are all greater than 1 and, if we plug them in for x, it makes the expression correct. The statement is not asking if x is greater than OR EQUAL to 1, only if it is greater than. Since 1 is NOT greater than 1, that is the answer.

The corollary states that for every positive real number ε, there exists a positive integer n such that

The corollary of the Archimedean principle states that for any positive real number ε, there exists a positive integer n such that ε is greater than the reciprocal of n, i.e., ε > 1/n. In other words, there exists a positive integer n such that the fraction 1/n is smaller than any given positive real number ε.

To prove this corollary, we can assume that ε is a positive real number. By the Archimedean principle, there exists a positive integer m such that m > ε. Now, consider the positive integer n = ⌈1/ε⌉ + 1, where ⌈x⌉ denotes the ceiling function, rounding up x to the nearest integer.

We have:

1/ε < 1/(⌈1/ε⌉ + 1) ≤ 1/(1/ε) = ε.

Therefore, we can conclude that for any positive real number ε, there exists a positive integer n = ⌈1/ε⌉ + 1 such that ε > 1/n.

Answer:

Step-by-step explanation:

1/4 of a painting in 2 weeks would be 1/8 painting for 1 week

Answer:

Solution given:

∆ ABE is similar to ∆ ACD

since their side will be proportional

AB/AC=AE/AD

AB/(AB+BC)=AE/(AE+ED)

63/(63+7)=(7x-40)/(7x-40+18)

9/10=(7x-40)/(7x-22)

doing crisscrossed multiplication

9(7x-22)=10(7x-40)

63x-198=70x-400

400-198=70x-63x

202=7x

x=202/7 or 28.85units.

Answer:

\(x=28\frac{6}{7}\)

\(x \approx 28.857\)

Step-by-step explanation:

It is given that lines (BE) and (CD) are parallel, thus (<AEB) and (EDC) are congruent by alternate interior angles theorem. Moreover, (<A) is shared between the two triangles, therefore it is also congruent. Hence, triangles (ABE) and (ACD) are similar by (angle-angle) similarity.

Side (AD) is composed of segments (AE) and (ED), therefore one can find the total measure of segment (AD):

AD = AE + ED

AD = 7x - 40 + 18

AD = 7x - 22

Side (AC) is made of segments (AB) and (BC), thus one can find the total length of the side (AC) by adding these two segments:

AC = AB + BC

AC = 63 + 7

AC = 70

When two triangles are similar, the ratios of the sides are equal. Therefore, one can make the following statement:

\(\frac{AE}{AD}=\frac{AB}{AC}\)

Substitute,

\(\frac{7x-40}{7x-22}=\frac{63}{70}\)

Cross products,

\(70(7x-40)=63(7x-22)\)

Distribute,

\(490x-2800=441x-1386\)

Inverse operations,

\(490x-2800=441x-1386\)

\(49x-2800=-1386\)

\(49x=1414\)

\(x=28\frac{6}{7}\)

R2 -> R2 - 3R1

a) To determine whether the vector (9,0,9) is a linear combination of the vectors (1,1,0), (1,0,1), (2,1,1) and (0,1,-1), we need to find coefficients c1, c2, c3 and c4 such that:

c1(1,1,0) + c2(1,0,1) + c3(2,1,1) + c4(0,1,-1) = (9,0,9)

This can be written as a system of linear equations:

c1 + c2 + 2c3 = 9

c1 + c3 + c4 = 0

c2 + c3 - c4 = 9

We can solve this system using row reduction:

[0 0 1 | 9/4]

We can see that the system has a unique solution, which is c1 = 9/2, c2 = 45/4, c3 = 0, and c4 = -9/4.

b) To determine whether the vectors (0,3,-1,2), (1,2,1,-2), and (3,0,5,-10) in \(R^4\) are linearly independent, we need to check whether the equation:

c1(0,3,-1,2) + c2(1,2,1,-2) + c3(3,0,5,-10) = (0,0,0,0)

has only the trivial solution c1 = c2 = c3 = 0.

To find:

All the numbers for which above equation holds true.

Solution:

\(x^{2} =5x+84\)

Let us solve the above equation by rearranging the terms and then let us find the roots of the equation.

The rectangular coordinates of the points of intersection of the polar curves r = 2sin(2θ) and r = 2sin(θ), the equations can be converted to rectangular form. However, solving the resulting system of equations algebraically may be challenging. Alternatively, graphing the polar curves and visually identifying the points of intersection can provide an effective method.

To find the rectangular coordinates of the points of intersection of the polar curves r = 2sin(2θ) and r = 2sin(θ), the equations can be converted to rectangular form, the rectangular coordinates of the above points are given below:

For the equation r = 2sin(2θ):

x = 2sin(2θ)cos(θ)

y = 2sin(2θ)sin(θ)

For the equation r = 2sin(θ):

x = 2sin(θ)cos(θ)

y = 2sin^2(θ)

The rectangular coordinates of the point(s) of intersection of the polar curves r = 2sin(2θ) and r = 2sin(θ) can be found by converting the polar equations to rectangular form and solving for the x and y coordinates.

To convert the polar equations to rectangular form, we can use the relationships x = rcos(θ) and y = rsin(θ). Substituting these expressions into the given polar equations, we get:

For the equation r = 2sin(2θ):

x = 2sin(2θ)cos(θ)

y = 2sin(2θ)sin(θ)

For the equation r = 2sin(θ):

x = 2sin(θ)cos(θ)

y = 2sin^2(θ)

To find the points of intersection, we need to set the x and y coordinates of both equations equal to each other and solve for θ. However, solving this system of equations algebraically can be complex due to the trigonometric functions involved.

Graphing the polar curves and visually inspecting the points of intersection may provide a more intuitive approach to finding the rectangular coordinates. By plotting both polar curves on a graph, the points where the curves intersect can be determined by their shared coordinates.

In summary, to find the rectangular coordinates of the points of intersection of the polar curves r = 2sin(2θ) and r = 2sin(θ), the equations can be converted to rectangular form.

To calculate the income Alice will receive in her first year of retirement, we need to consider her pension fund, the state pension, and the annuity rates.

Given: Alice's salary: £55,000

Her contributions to the pension scheme: 8% of salary

Employer contributions and tax relief: 4% of salary

Retirement age: 66

State pension: £9,000 per year

First, let's calculate Alice's pension fund. She has been in the scheme from age 35 to 66, which is a total of 31 years. During this period, she has made contributions of 8% of her salary, topped up by 4% from the employer and tax relief. So, her annual contributions are (8% + 4%) of £55,000 = £5,500.

Her total pension fund would be £5,500 x 31 = £170,500.

Next, let's consider the annuity rates. Annuity rates determine the income that can be purchased with the pension fund. The rates vary based on factors such as age, gender, and prevailing market conditions.

Using the annuity rates, Alice can calculate the income she will receive from her pension fund. Let's assume the annuity rate is 5% per year. So, the income from her pension fund would be £170,500 x 5% = £8,525.

Finally, we add the state pension to calculate Alice's total income in her first year of retirement:

Total income = Pension fund income + State pension

Total income = £8,525 + £9,000 = £17,525.

Therefore, Alice will receive £17,525 as her income in the first year of retirement.
