We can see here that the problem that can be solved using synthetic division is: A. [tex]\frac{2y^{2} + 4y - 6}{y-1}[/tex]

Synthetic division is a simplified method of polynomial division, used to divide a polynomial by a linear factor of the form (x - a). This method can be used to quickly evaluate a polynomial for a particular value of x, or to find the roots of a polynomial equation.

In order to solve with synthetic division, we have:

Step 1: Make the denominator to equal zero. The numerator is written in descending order.

Step 2: Bring the first number or the leading coefficient straight down.

Step 3: Put the result in the next column by multiplying the number in the division box with the number you brought down.

Step 4: Write the result at the bottom of the row by adding the two numbers together

Step 5: Until you reach the end of the problem, repeat steps 3 and 4.

9 is the centre of enlargement in triangle .

What is a triangle, exactly?

A triangle, a three-sided polygon, is made up of three vertices. When the triangle's three sides are joined end to end at a single point, the angles are created. Three angles in a triangle add up to 180 degrees in total. A triangle is a closed, two-dimensional geometry with three sides, three angles, and three vertices. Triangles are also a type of polygon.

First draw lines from point O through A, B and C, as shown in the diagram

Measure the length O A and multiply it by 1.5 to get the distance from O of the image point A'.

      O A' = 1.5 × O A

       OA' = 1.5 * √(4 - 0)² + (4 - 0)²

              = 1.5*4√2

       OA' = 6

Mark the point A' on the diagram

The images B' and C' can then be marked in a similar way and the enlarged triangle A' B' C' can then be drawn.

OB' = 1.5OB

OB' = 1.5 √(4 - (-2))² + ( 4 -0 )²

OB' = 1.5*2√13

 OB' = 3√13

 OC' = √1.5 * √(4 - (-2))² + 4 - 4

 OC' = 1.5*6

   OC' = 9

Answer: $2240.59

Step-by-step explanation:

To calculate the compound interest paid when an amount is borrowed at 5% p.a for 26 years and compounded monthly, you can use the formula:

A = P(1 + r/n)^(nt)

where:

A = the amount of money you will have after t years

P = the principal amount (the amount borrowed)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the time (in years) for which the money is borrowed

In this case, we have:

P = the amount borrowed (not given in the question)

r = 5% p.a, or 0.05 as a decimal

n = 12 (since the interest is compounded monthly)

t = 26 years

We need to find the amount of compound interest paid, so we need to find the difference between the amount of money you will have after 26 years (A), and the amount you borrowed (P).

Let's assume the amount borrowed (P) is $1000. Then, we can substitute these values into the formula:

A = 1000(1 + 0.05/12)^(12*26)

A = 1000(1.004167)^312

A = 1000(3.240590)

A = $3240.59

So, after 26 years, the amount of money you will have is $3240.59. The compound interest paid is the difference between the amount borrowed and the final amount:

Compound interest paid = $3240.59 - $1000

Compound interest paid = $2240.59

Therefore, the compound interest paid if the amount is borrowed at 5% p.a for 26 years and compounded monthly is $2240.59.

A = $36,594.00

A = P + I

where

P (principal) = $10,000.00

I (interest) = $26,594.00

First, convert R as a percent to r as a decimal

r = R/100

r = 5/100

r = 0.05 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 10,000.00(1 + 0.05/12)(12)(26)

A = 10,000.00(1 + 0.0041666666666667)(312)

A = $36,594.00

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $10,000.00 at a rate of 5% per year compounded 12 times per year over 26 years is $36,594.00.

The average rate of increase is $69 per year (to the nearest dollar).

What is average rate of increase?

The  function is defined as the average rate at which one measurement is changing(here increasing) with respect to another change. So an average rate of change function is a system that calculates the amount of change in one data divided by the corresponding amount of change in another.

The fees in 1997( x₁ say) was $3042( y₁ say)

fees in 2000(x₂ say) was $3250 ( y₂ say)

The formula is for change in average rate is  [tex]\frac{ y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

average rate of increase= (3250-3042)/(2000-1997)

                                        = 208/3

                                         =69.33

so average rate of increase to the nearest dollar  is $69 per year.

The correct answer to the given question about possibility of the license plate is 7, 894, 720.

This problem involves counting the number of possible license plates that can be created with certain restrictions. The first two digits must be odd and repetition is not permitted. The remaining five characters can be any uppercase letter, also without repetition. By using the multiplication principle of counting, we can calculate the total number of possible license plates by multiplying the number of choices for each character position. In this case, we obtain a total of 7,894,720 possible license plates. For the first digit, there are 5 odd digits to choose from (1, 3, 5, 7, 9). After choosing the first odd digit, there are only 4 odd digits left to choose from for the second digit since repetition is not permitted.

For the third, fourth, and fifth characters, there are 26 uppercase letters to choose from for each character, with repetition not permitted. Therefore, the total number of possible license plates is:

5 × 4 × 26 × 26 × 26 × 26 × 26 = 7,894,720

So the correct answer is 7,894,720.

Ball A reaches a greater height than Ball B.

To determine which ball reaches a greater height, we need to compare the maximum height each ball reaches.

For Ball A, we can use the formula for the vertex of a parabola, which is given by [tex]x = - \frac{b}{2a} [/tex], where a and b are the coefficients of the quadratic equation in standard form (ax² + bx + c = 0). In this case, a = -4.9 and b = 14.7, so the vertex of Ball A's path is at [tex]x = \frac{ - 14.7}{2 \times 4.9} = 1.5 [/tex] seconds.

To find the maximum height of Ball A, we can plug this value into the original equation:

[tex]f(1.5) = -4.9 \times {1.5}^{2} + 14.7(1.5) + 0.975 = 9.9 \: \: meters.[/tex]

For Ball B, we can look at the table and see that it reaches a maximum height of 8 meters.

Therefore, Ball A reaches a greater height than Ball B by 1.9 meters (9.9 - 8 = 1.9)

We can answer this question without graphing either function by using the properties of quadratic functions. The maximum height of a quadratic function occurs at the vertex, which can be found using the formula x = -b/2a. We can then plug this value into the function to find the maximum height. By comparing the maximum heights of the two balls, we can determine which ball reaches a greater height.

The minimum value of the function g(x) = (x-3)² occurs at the vertex of the parabola, which is located at x = 3. At this point, the value of the function is g(3) = (3-3)² = 0.

To see why this is the case, we can use the fact that the vertex of a parabola in the form f(x) = a(x-h)² + k is located at (h,k). In the case of g(x) = (x-3)², we have a = 1, h = 3, and k = 0, so the vertex is located at (3,0).

Since the parabola opens upwards (the coefficient a is positive), the value of the function is minimized at the vertex.

Therefore, the minimum value of g(x) is 0, which occurs at x = 3.

The solutions to the equation are approximately x = 0.89 and x = -0.89.

Squares as well as square root both ideas are diametrically opposed to one another. Squares are the numbers that are produced when a value is multiplied by itself. In contrast, a number's square root is a value that, when multiplied by itself, returns the original value. Both are hence vice-versa approaches. For instance, 2 is squared to provide 4, and 2 is the square root of 4, giving 2.

When n is a number, its square is denoted by n raised to the power 2, or n2, and its square root is denoted by the symbol "n," where "n" is referred to as a radical. The term "radicand" refers to the value under the root symbol.

The given equation is 5x² + 2 = 6.

5x² = 4

Answer:

  ∠Z = 52°

Step-by-step explanation:

You want to know the measures of an angle and a variable in the given quadrilaterals with angles marked.

Segment WY divides the figure into two congruent triangles, so you know angles X and Z have the same measure. The sum of angles in a quadrilateral is 360°, so ...

  ∠W +∠X +∠Y +∠Z = 360°

  134° +∠Z +122° +∠Z = 360° . . . . . . use ∠Z for ∠X

  2·∠Z = 104° . . . . . . simplify, subtract 256°

  ∠Z = 52°

Opposite angles of a rhombus are congruent, so ...

  2b = b +59°

  b = 59° . . . . . . . . . subtract b

Take note that Bus 18 is the most reliable in terms of trip times among the line plots shown above. With our understanding of the interquartile range, we can solve this. (IQR)

We must compare the metrics of data variability in order to identify the bus that consistently produces the best accurate results. Range and interquartile range are the metrics of variability that we can utilise in this situation (IQR).

The IQR is the difference between the third quartile (Q3) and the first quartile, whereas the range is the difference between the highest and lowest values in the data set (Q1). Because it is less impacted by extreme values than the range, the IQR provides a more accurate indicator of variability.

Using the given data, we can calculate the range and IQR for each bus:

Bus 47:

Range = 28 - 4 = 24

Q1 = 10, Q3 = 22

IQR = 22 - 10 = 12

Bus 18:

Range = 22 - 6 = 16

Q1 = 9, Q3 = 25

IQR = 25 - 9 = 16

According to these findings, Bus 18 has a narrower range and a higher IQR than Bus 47. The IQR, a more accurate indicator of variability in this situation, reveals that Bus 18's trip times are less variable than those of Bus 47's. Hence, we can say that when it comes to trip times, Bus 18 is the most reliable.

the correct answer to the given question about car loan is option D: $2,315.38; $383.22.

To determine the interest and monthly payment for the car loan, we can use the add-on interest formula:

Total Interest = Principal x Rate x Time

where:

Principal = $16,079 (the amount of the loan)

Rate = 3.6% (the add-on interest rate)

Time = 4 years

Total Interest = $16,079 x 0.036 x 4

Total Interest = $2,315.38

So the total amount of interest on the loan is $2,315.38.

To calculate the monthly payment, we can use the following formula:

Monthly Payment = (Principal + Total Interest) / (Number of Payments)

where:

Principal = $16,079 (the amount of the loan)

Total Interest = $2,315.38 (the total interest on the loan)

Number of Payments = 4 x 12 = 48 (since the loan is for 4 years, and there are 12 months in a year)

Monthly Payment = ($16,079 + $2,315.38) / 48

Monthly Payment = $383.22

Therefore, the amount of interest on the loan is $2,315.38 and the monthly payment for the car loan is $383.22.
