Find the area of the parallelogram 9m 4m A=b×h =[].9 =[]m2​

According to the question we can conclude that the percent decrease in the number of available parking spots is 4.5%.

In mathematics, a percentage is a number or ratio that's also expressed as just a fraction from 100. Occasionally, the acronyms "pct.," "pct," as well as "pc" are also used. Yet it is commonly indicated by the percent sign, "%." The % amount has no dimensions. Percentages are essentially fractions when the denominator is 100. Use the percent sign (%) to indicate that what a number is just a percentage by placing it next to it. For instance, you score a 75% if you properly answered 75 out of questions in total on something like a test (75/100). Divide the money even by total as well as multiply the outcome by 100 to calculate percentages. The formula for calculating the percentage is (value/total) x 100%.

Given,

To find the percent decrease in the number of available parking spots, we need to calculate the difference between the initial number of parking spots and the new number of parking spots, and express it as a percentage of the initial number of parking spots.

The initial number of parking spots is 1400, and the new number of parking spots after the library is built is 1400 - 63 = 1337.

The difference between the initial number of parking spots and the new number of parking spots is 1400 - 1337 = 63.

To express this difference as a percentage of the initial number of parking spots, we divide the difference by the initial number and multiply by 100:

(63 / 1400) x 100 = 4.5%

Therefore, the percent decrease in the number of available parking spots is 4.5%.

o show that 4.57 (5 and 7 recurring) is equal to 4 and 19/33, we can use algebraic equations. First, let x = 4.57 (5 and 7 recurring), then we multiply both sides by 100 to get 100x = 457.5757... Next, we subtract x from 100x to get 99x = 453. Thus, x = 453/99. We can simplify this fraction by dividing both the numerator and denominator by 3, giving us 151/33. Finally, we can write 151/33 as a mixed number, which is 4 and 19/33. Therefore, we have shown that 4.57 (5 and 7 recurring) is equal to 4 and 19/33 using algebraic equations.

Step-by-step explanation:

After 3 years, there will be $2,810.95 in the Richardsons' account and the interest earned on the Richardsons' investment after 3 years will be around $310.95.

(a) The interest rate per month is r = 1.36% ÷ 12 = 0.01133333. The number of compounding periods in 3 years is n = 3 × 12 = 36. Therefore, the amount A after 3 years is:

A = 2500 × (1 + r)ⁿ

A = 2500 × (1 + 0.01133333)³⁶

A = $2,810.95

Therefore, after 3 years, there is $2,810.95 in the Richardsons' account.

(b) The interest earned is the difference between the final amount and the initial investment:

Interest = A - P

I = $2,810.95 - $2,500

I = $310.95

Therefore, the interest earned on the Richardsons' investment after 3 years is $310.95.

Depreciation is an annual income tax deduction that enables you to recoup the purchase price or other basis of a specific item over the course of its use.

It is a provision for the property's normal wear and tear, degeneration, or obsolescence.

As the years pass, the car's value drops.

This process is known as depreciation.

Depreciation is the decrease in asset value brought on by normal wear and tear.

Use this formula to calculate the annual rate of change:

g = (FV/PV)¹⁾ⁿ - 1

Now, using the formula calculate as follows:

(11000/3900)¹⁾⁸ - 1

-0.1463 = -14.63%

The surface area of the cylinder has a radius of 8cm and a height of 6cm is 703.36 square feet.

To calculate the surface area of a cylinder, we need to add the area of the top and bottom circles to the area of the curved side.

The formula for the area of a circle is:

A = [tex]\pi r^2[/tex]

where A is the area, π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius.

The formula for the curved surface area of a cylinder is:

C = 2πrh

where C is the curved surface area, r is the radius, and h is the height of the cylinder.

Given that the radius is 8cm and the height is 6cm, we can calculate the surface area as follows:

Area of top circle =

Area of bottom circle =[tex]\pi r^2[/tex] = 3.14 x [tex]8^2[/tex] = 200.96 cm square

Curved surface area = 2πrh = 2 x 3.14 x 8 x 6 = 301.44 cm square

Therefore, the total surface area of the cylinder is:

Total surface area = Area of top circle + Area of bottom circle + Curved surface area

Total surface area = 200.96 [tex]cm^2[/tex] + 200.96 [tex]cm^2[/tex] + 301.44 [tex]cm^2[/tex]

Total surface area = 703.36 [tex]cm^2[/tex]

The probability of a customer ordering both marinara and pesto sauces is 0.43.

We can use the inclusion-exclusion principle to find P(marinara and pesto):

P(marinara or pesto) = P(marinara) + P(pesto) - P(marinara and pesto)

We know that P(marinara or pesto) = 0.93 and P(marinara) = 0.74, and P(pesto) = 0.62. Substituting these values in the above equation, we get:

0.93 = 0.74 + 0.62 - P(marinara and pesto)

P(marinara and pesto) = 0.74 + 0.62 - 0.93

Answer:

If the average rates of return are the same for both companies, but one company has a much larger standard deviation of its rates of return. You should invest in a company with a smaller standard deviation.

This is the better choice because a larger standard deviation means that the company's returns are more variable, which implies more risk. While higher risk can result in higher returns, it can also result in significant losses. Investing in a company with a smaller standard deviation of its rates of return will likely result in a more stable return on investment and therefore be a safer investment.

In general, investors should consider both the average and variability returns when making investment decisions. While higher average returns are desirable, they may not be worth the additional risk if the variability of returns is too high.

The reason is that asking every student at a local movie theater is a form of convenience sampling, where the sample is chosen based on convenience and accessibility, rather than being selected randomly from the entire population of interest. It may not provide a representative sample of the community's music preferences since the population of students who attend a movie theater may not be the same as the general population of students in the community.

Answer:

y=-5x+6

Step-by-step explanation:

Slope-intercept form is y=mx+b, with m being the slope and b being the y-intercept.

The y-intercept is where the line crosses over the y-axis. In this case, there is a point on 6, which means 6 is our y-intercept.

Next, we need to calculate the slope. We know slope = rise/run.

Start at the point -9,3. We rise 5 and go left 1 to get to the point -4,2.

Since we went left, our slope is 5/-1, which simplifies to -5.

Our final answer, written in slope intercept form, is y=-5x+6

The measure of the angle ADC in circle B is 23 degrees.

A circle is a particular type of ellipse in mathematics or geometry where the eccentricity is zero and the two foci are congruent. A circle is also known as the location of points that are evenly spaced apart from the centre. The radius of a circle is measured from the centre to the edge. The line that splits a circle into two identical halves is its diameter, which is also twice as wide as its radius.

A circle is a fundamental 2D form whose radius is quantified. The interior and exterior parts of the aircraft are separated by the circles. It resembles a line segment in several ways.

For the given circle B, the measure of angle ABC is 46 degrees.

Now, the angle subtended by the circle is half the angle subtended at the center.

Angle ADC = 1/2(angle ABC)

Angle ADC = 1/2(46)

Angle ADC = 23 degrees.

When diagonalizing Matrix A = PDP^(-1) and λ1 = (1 + √5)/2 and λ2 = (1 - √5)/2 are the eigenvalues of A, and [0 1] is an eigenvector associated with both λ1 and λ2.

To diagonalize a matrix, we need to find its eigenvalues and eigenvectors. Let's begin by finding the eigenvalues of A.

The characteristic equation is given by:

det(A - λI) = 0

where I is the identity matrix and λ is the eigenvalue.

For matrix A, we have:

A - λI = [1 - λ 0 ]

[6 -1 - λ]

det(A - λI) = (1 - λ)(-1 - λ) - 6(0) = λ^2 - λ - 1 = 0

Using the quadratic formula, we find that the eigenvalues are:

λ1 = (1 + √5)/2

λ2 = (1 - √5)/2

Now let's find the eigenvectors associated with each eigenvalue. For λ1 = (1 + √5)/2, we have:

(A - λ1I)x = 0

[1 - λ1 0] [x1] = [0]

[6 -1 - λ1] [x2] [0]

which simplifies to:

[-(√5-1)/2 0] [x1] = [0]

[6 -√5-1] [x2] [0]

From the first row, we have x1 = 0. Substituting this into the second row, we get:

(√5+1)x2 = 0

Since x2 cannot be zero (otherwise the eigenvector would be the zero vector), we have:

x2 = 1

Therefore, the eigenvector associated with λ1 is:

v1 = [0 1]

Similarly, for λ2 = (1 - √5)/2, we have:

(A - λ2I)x = 0

[1 - λ2 0] [x1] = [0]

[6 -1 - λ2] [x2] [0]

which simplifies to:

[-(√5+1)/2 0] [x1] = [0]

[6 -√5+1] [x2] [0]

From the first row, we have x1 = 0. Substituting this into the second row, we get:

(√5-1)x2 = 0

Again, since x2 cannot be zero, we have:

x2 = 1

Therefore, the eigenvector associated with λ2 is:

v2 = [0 1]

Now we can use the eigenvectors to diagonalize the matrix. The diagonal matrix D will have the eigenvalues on the diagonal and zeros elsewhere. The matrix P will have the eigenvectors as columns.

D = [λ1 0]

[0 λ2]

P = [v1 v2] = [0 0]

[1 1]

To check that this is the correct diagonalization, we can verify that:

A = PDP^(-1)

where P^(-1) is the inverse of P. Since P is not invertible (the columns are linearly dependent), we can use the pseudoinverse instead:

A = PD†P

where D† is the pseudoinverse of D. We have:

we have diagonalized A as:

A = PDP^(-1)

where:

D = [λ1 0]

[0 λ2]

P = [v1 v2] = [0 0]

[1 1]

and λ1 = (1 + √5)/2 and λ2 = (1 - √5)/2 are the eigenvalues of A, and [0 1] is an eigenvector associated with both λ1 and λ2.

A quadrilateral which have opposite side are parallel and equal to each other.

area of the parallelogram ABCD,

find the equations of the lines AB and BC:

Line AB passes through the points A(-4,2) and B(-4,-3):

slope = (y2 - y1)/(x2 - x1) = (-3 - 2)/(-4 - (-4)) = -5/0 = undefined

Since the slope is undefined, the line is vertical and has the equation x = -4.

Line BC passes through the points B(-4,-3) and C(2,-3):

slope = [tex]\frac{(y2 - y1)}{(x2 - x1)}[/tex] = [tex]\frac{-3 - (-3)}{(2 - (-4)}[/tex]) = 0

Since the slope is 0, the line is horizontal and has the equation y = -3.

The height corresponding to AB is the perpendicular distance between AB and CD, which is the vertical distance between the lines x = -4 and x = 2. This distance is 6 units.

The height corresponding to BC is the perpendicular distance between BC and AD, which is the horizontal distance between the lines y = -3 and y = 2. This distance is 5 units.

Since the height corresponding to BC is shorter, we use it as the height of the parallelogram. The base is BC, which has a length of 6 units. Therefore, the area of the parallelogram is:

Area = base × height = 6 × 5 = 30 square units.

the equation of the line that passes through the 7 points (1, 3), (2, 5),

(3, 7), (4, 9), (5, 11), (6, 13), and (7, 15) is y = 2x + 1.

The point-slope form of a linear equation is a way to write the equation of a line when you have a known point on the line and the slope of the line. The point-slope form is written as:

[tex]y - y_{1} = m(x - x_{1} )[/tex]

where m is the slope of the line, and (x1, y1) is the known point on the line.

The 7-point slope form is a variation of the point-slope form that requires knowing 7 points on the line, rather than just one. It is written as:

[tex](y - y_{1} ) = ((y_{2} - y_{1} ) / (x_{2} - x_{1} ))(x - x_{1} )[/tex]

where[tex](x_{1} , y_{1} ) and (x_{2} , y_{2} )[/tex] are two points on the line with known coordinates, and m is the slope of the line, which can be calculated using the two points.

To use the 7-point slope form to write the equation of a line, you need to know the coordinates of 7 points that lie on the line. Once you have these coordinates, you can choose any two of them to use as [tex](x1, y1) and (x2, y2)[/tex] in the formula, and then solve for the slope m. Once you have the slope, you can plug in the coordinates of any one of the 7 points into the 7-point slope form to find the equation of the line.

For example, let's say we have the following 7 points on a line: (1, 3), (2, 5), (3, 7), (4, 9), (5, 11), (6, 13), and (7, 15).

We can choose any two of these points to use as[tex](x_{1} , y_{1} ) and (x_{2} , y_{2} )[/tex] in the 7-point slope form. Let's choose (1, 3) and (2, 5).

The slope m can be calculated as:

[tex]m = (y_{2} - y_{1} ) / (x_{2} - x_{1} )[/tex]

m = (5 - 3) / (2 - 1)

m = 2

Now we can plug in the values of[tex](x_{1} , y_{1} )[/tex] , m, and x into the 7-point slope form to get the equation of the line:

[tex](y_{2} - y_{1} ) =m (x_{2} - x_{1} )[/tex]

(y - 3) = 2(x - 1)

y - 3 = 2x - 2

y = 2x + 1

So the equation of the line that passes through the 7 points (1, 3), (2, 5), (3, 7), (4, 9), (5, 11), (6, 13), and (7, 15) is y = 2x + 1.

In summary, the 7-point slope form is a variation of the point-slope form that requires knowing the coordinates of 7 points on a line. Once you have these coordinates, you can use the 7-point slope form to find the equation of the line.

By paying off the higher interest card first, we save $1932 - $1579 = $353 in interest charges over the course of 56 months.

The conventional method is to pay off the credit card with the highest interest rate first if we have two credit cards with differing interest rates. We can figure out how much money we save by reworking the issue to pay off the card with the lowest interest rate first.

Consider that we have two credit cards: Card A, which has a $5,000 debt and a 15% interest rate, and Card B, which has a balance of $3,000 and a 10% interest rate. We can save money by lowering the interest paid on Card B while still making minimum payments on Card A if we pay that card off first.

It would take us around 22 months to pay off Card B and 36 months to pay off Card A if we made the minimum payments of $300 on Card B and $150 on Card A each month. We would pay interest on Card A in total of $1932 and Card B in total of $386 throughout this time.

Instead, if we pay off Card A first, we would devote the remaining $300 to Card A until it is completely paid off while continuing to make the minimum payments on Card B. We would need around 24 and 32 months, respectively, to pay off Card A and Card B. We would pay interest on Card A for a total of $1579 and Card B for a total of $282 during this time.

We therefore save $1932 - $1579 = $353 in interest fees over the course of 56 months by paying off the higher rate card sooner.
