Answer:

the new perimeter of the land is 40m

Step-by-step explanation:

The computation of the new perimeter of the land is given below:

Since the square plot is 81m^2

It could be increased by 19m^2

So the total would be

= 81m^2 + 19m^2

= 100m^2

Each side is 10m

Now the perimeter is sum of all sides

= 10m + 10m + 10m + 10m

= 40m

hence, the new perimeter of the land is 40m

Essa conta poderia ser feita de várias maneiras. Uma delas é dividir 450 por 3 e depois multiplicar por 5. A resposta para esse problema é 750.

The yield to maturity of a ten-year, $1000 bond with a 5.2% coupon rate and semi-annual coupons, if the =bond is currently trading for a price of $884, is 6.23%. Thus, option a and option b is correct

Yield to maturity (YTM) is the anticipated overall return on a bond if it is held until maturity, considering all interest payments. To calculate YTM, you need to know the bond's price, coupon rate, face value, and the number of years until maturity.

The formula for calculating YTM is as follows:

YTM = (C + (F-P)/n) / ((F+P)/2) x 100

Where:

C = Interest payment

F = Face value

P = Market price

n = Number of coupon payments

Given that the bond has a coupon rate of 5.2%, a face value of $1000, a maturity of ten years, semi-annual coupon payments, and is currently trading at a price of $884, we can calculate the yield to maturity.

First, let's calculate the semi-annual coupon payment:

Semi-annual coupon rate = 5.2% / 2 = 2.6%

Face value = $1000

Market price = $884

Number of years remaining until maturity = 10 years

Number of semi-annual coupon payments = 2 x 10 = 20

Semi-annual coupon payment = Semi-annual coupon rate x Face value

Semi-annual coupon payment = 2.6% x $1000 = $26

Now, we can calculate the yield to maturity using the formula:

YTM = (C + (F-P)/n) / ((F+P)/2) x 100

YTM = (2 x $26 + ($1000-$884)/20) / (($1000+$884)/2) x 100

YTM = 6.23%

Therefore, If a ten-year, $1000 bond with a 5.2% coupon rate and semi-annual coupons is now selling at $884, the yield to maturity is 6.23%.

The evaluation of the expression is 2, if the expression is x - y + z(x + w).

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

Given that x = 1, y = 1, w = 1, and z = 1

We have been given expression

⇒ x - y + z(x + w)

Substitute the values of x = 1, y = 1, w = 1, and z = 1 in the above expression,

The limit lim(x→∞) x/√(x^2 + 3) is 1, and there is no need to apply L'Hospital's Rule in this case.

When trying to use L'Hospital's Rule to find the limit lim(x→∞) x/√(x^2 + 3), it is important to note that L'Hospital's Rule can only be applied if the function is continuous and differentiable. In this case, the function is continuous and differentiable, but applying L'Hospital's Rule is not necessary as the limit can be evaluated using another method.
First, let's rewrite the given function by dividing both the numerator and the denominator by x:
lim(x→∞) (x/x) / (√(x^2 + 3)/x) = lim(x→∞) 1 / √(1 + 3/x^2)
As x approaches infinity, the term 3/x^2 approaches 0, so the limit becomes:
lim(x→∞) 1 / √(1 + 0) = 1 / √(1) = 1
Therefore, the limit lim(x→∞) x/√(x^2 + 3) is 1, and there is no need to apply L'Hospital's Rule in this case.

Thus, the intermediate step in the form (x+a)² = b as a result of completing the square for the given equation is - (x + 10)² = 1 /3.

A quadratic equation can be made together into perfect square trinomial simply adding or removing elements from both sides, a technique known as "completing the square."

You can use the square's completion as another mathematical tool to solve a variety of problems:

Given expression:

-3x² - 298 = 60x - 1

isolating the x values:

-3x² - 60x = 298 - 1

-3x² - 60x = 299

Taking -3 common from the left hand side:

-3(x² + 20x) = 299

x² + 20x = - 299/3

This, can be written as:

x² + 2*10x = - 299/3

add both side by 100

x² + 2*10x + 100 = - 299/3 + 100

On simplification:

(x + 10)² = (-299 + 300) /3

(x + 10)² = 1 /3

Comparing obtained expression with the given form: (x+a)²=b

a = 10 and b = 1/3

Thus, the intermediate step in the form (x+a)² = b as a result of completing the square for the given equation is - (x + 10)² = 1 /3.

The smallest possible value of doughnuts in each box is 2. The smallest possible value of doughnuts in each box is 2.

In order for Donna to rearrange the remaining doughnuts into bags so that each bag contains the same number of doughnuts and none are left over, the number of doughnuts in each box must be divisible by the number of bags. Since there are no doughnuts left over, this means that the number of doughnuts in each box must be a multiple of the number of bags.

To find the smallest possible value, we need to find the smallest common multiple of the numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9 (since there are 9 possible numbers of bags). The smallest common multiple of these numbers is 2, so the smallest possible value of doughnuts in each box is 2.Therefore, the smallest possible value of doughnuts in each box is 2.

Anna have left \(\$180\) money.

In the given question,

Anna saved \(\$40\) each month from babysitting for \(1\) and \(1/4\) years.

She spent \(70\%\) of her savings on a computer.

We have to find the money that left for Anna.

Anna saved \(\$40\) each month.

She saved money for \(1\) and \(1/4\) years.

As we know that in a year have \(12\) months.

Now we finding the months in \(1/4\) years.

Since \(1\) year \(=12\) months

So \(1/4\) years \(=12/4\) months

So \(1/4\) years \(=3\) months

Now we finding the total months in \(1\) and \(1/4\) years.

There have \(12+3=15\) months in \(1\) and \(1/4\) years.

Now find the total money that Anna saved.

\(=\$40\times15\\=\$600\)

Hence, Anna saved \(\$600\) in  \(1\) and \(1/4\) years.

She spend \(70\%\) of her saving.

Now finding how much she spend on buying computer.

So Spend Money for Computer \(=\$600\times70\%\)

Since percent is shows the ration with \(100\). So we can write \(70\%\) as \(70/100\). Now the equation is

Spend Money for Computer \(=\$600\times\frac{70}{100}\)

Simplifying

Spend Money for Computer \(=\$6\times70\)

Spend Money for Computer \(=\$420\)

Now we finding the left money after buying the computer.

She saved total money \(=\$600\)

Spend Money for Computer \(=\$420\)

Now Left Money \(=\$600-\$420\)

Now Left Money \(=\$180\)

 The slope of a line can be determined using two points on the line. Given the coordinates (3,10) and the point obtained by going right 2 and down 7, the slope of the line can be calculated.

To find the slope of the line, we can use the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the coordinates of two points on the line.
Using the given point (3,10) as (x1, y1), and the point obtained by going right 2 and down 7 as (x2, y2), we have:
x1 = 3, y1 = 10
x2 = 3 + 2 = 5, y2 = 10 - 7 = 3
Plugging these values into the slope formula:
m = (3 - 10) / (5 - 3)
Simplifying:
m = -7 / 2
Therefore, the slope of the line is -7/2. This means that for every 2 units of horizontal change (right or left), the line decreases by 7 units vertically.
