Rounding to the nearest cent, the estimated value of the vehicle after 4 years is approximately $23,726.20..

To estimate the value of the vehicle after 4 years, we can use the given equation A = 39500(0.86)^t, where A represents the value of the vehicle and t represents the number of years.

Substituting t = 4 into the equation:

A = 39500(0.86)^4

A ≈ 39500(0.5996)

A ≈ 23726.20

Rounding to the nearest cent, the estimated value of the vehicle after 4 years is approximately $23,726.20.

This estimation is based on the assumption that the vehicle's value decreases by 14% each year. The equation A = 39500(0.86)^t models the exponential decay of the vehicle's value over time. By raising the decay factor of 0.86 to the power of 4, we account for the 4-year period. The final result suggests that the value of the vehicle would be around $23,726.20 after 4 years of ownership.

Answer:

3400, If it's a decimal version then, 3.39

Step-by-step explanation:

3,389

The 8 is after the 3/the hundreds place. So you round the 8 because the 8 is greater then 5 and then you get 3,400. Decimal version: 3.34, the hundreds place in the decimal is the second digit to the right of the period. 3.389 = 3.34 9 is greater then 5. Your welcome :)

Answer:

\( y = \frac{3}{4}x - \frac{1}{4} \)

Step-by-step explanation:

First, find the slope using the points (3, 2) and (-1, -1):

Slope = \( m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-1 - 2}{-1 - 3} = \frac{-3}{-4} = \frac{3}{4} \)

Find the y-intercept, b, by substituting x = -1, y = -1 and m = ¾ in y = mx + b.

-1 = ¾(-1) + b

-1 = -¾ + b

Add ¾ to both sides

-1 + ¾ = b

(-4 + 3)/4 = b

-¼ = b

Substitute m = ¾ and b = -¼ in y = mx + b.

The equation would be:

✅\( y = \frac{3}{4}x - \frac{1}{4} \)

The required permutation of the letters of the word coefficient provided that all words start with coe is equals to 40,320.

The number of permutations of the letters of  word coefficient

With the condition that all words start with 'coe'.

Since we are given that the first three letters must be "coe",

Required to permute the remaining 8 letters.

The number of permutations of 8 letters can be found,

Using the formula for permutations of n distinct objects, which is,

P(n) = n!

where n is the number of objects.

Since the first three letters are fixed as 'coe',

The order of these letters is not counted in the permutation.

So, the number of permutations of the 8 remaining letters is,

⇒P(8) = 8!

⇒P(8) = 40,320

Therefore, the total number of permutations of the letters in the word 'coefficient' that start with 'coe' is P(8) = 40,320.

Part A: The measures of center in Mountain View School, mean = 4.75, median = 4.5 and Bay Side School, mean = 5.5, median = 4.5

Part B: The measures of variability: Mountain View School, Range= 9 IQR= 4,  Bay Side School, Range= 10 IQR= 3

Part C: Bay Side School would be the better choice.

Part A: Measures of Center

To calculate the measures of center, we will determine the mean and median for each school.

Mountain View School:

Mean = (0 + 5 + 6 + 8 + 9 + 8 + 2 + 0) / 8 = 38 / 8 = 4.75

Median = (4 + 5) / 2 = 4.5

Bay Side School:

Mean = (10 + 2 + 4 + 5 + 6 + 8 + 8 + 7 + 6 + 5 + 5 + 4 + 4 + 3 + 1 + 0) / 16 = 88 / 16 = 5.5

Median = (4 + 5) / 2 = 4.5

Part B: Measures of Variability

To calculate the measures of variability, we will determine the range and interquartile range (IQR) for each school.

Mountain View School:

Range = 9 - 0 = 9

IQR = (6 - 2) = 4

Bay Side School:

Range = 10 - 0 = 10

IQR = (6 - 3) = 3

Part C: Choice based on Class Size

If you are interested in a larger class size, Bay Side School would be the better choice. The mean class size at Bay Side School is 5.5, while at Mountain View School it is 4.75. The range of class sizes at Bay Side School is also larger (10) compared to Mountain View School (9). This indicates that there is a greater variation in class sizes at Bay Side School, providing a higher likelihood of finding larger class sizes. However, it's important to consider other factors such as teaching quality, resources, and overall educational environment before making a final decision.

Answer:

The rate of change (m) = 1.1

Option B is correct option.

Step-by-step explanation:

Which rate of change (m), would represent this proportional relationship?

Rate of change can be found using slope formula:

\(Slope=\frac{y_2-y_1}{x_2-x_1}\)

You can choose any two values of x and y from the table. I am choosing 1st and 2nd values

From the table we get: \(x_1=2, y_1=2.2, x_2=4, y_2=4.4\)

Putting values in the formula and finding slope (rate of change)

\(Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{4.4-2.2}{4-2}\\Slope=\frac{2.2}{2}\\Slope=1.1\)

So, slope m = 1.1

The rate of change (m) = 1.1

Option B is correct option.

Answer:

D = -j = -h/-k

Step-by-step explanation:

If l || m the values of x and y are x = 8, y = 21.

What are the parallel and perpendicular lines?

Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect. Perpendicular lines are lines that intersect at a right (90 degrees) angle.

(7x + 12)° and (12x - 28)° are alternate interior angles. Alternate interior angles are congruent. Therefore:

(7x + 12)° = (12x - 28)°

Solve for x

7x + 12 = 12x - 28

Collect like terms

7x - 12x = - 12 - 28

-5x = -40

Divide both sides by -5

-5x/-5 = -40/-5

x = 8

(12x - 28)° + (9y - 77)° = 180° (linear pair)

To find y, plug in the value for x = 8.

12(8) - 28 + 9y - 77 = 180

96 - 28 + 9y - 77 = 180

Combine like terms

- 9 + 9y = 180

Add 9 to both sides

-9 + 9y + 9 = 180 + 9

9y = 189

Divide both sides by 9

9y/9 = 189/9

y = 21

Hence, if l || m the values of x and y are x = 8, y = 21.

(3xy³ + 5x²y⁴)  (3xy³ - 5x²y⁴)

Step-by-step explanation:

Factorize polynomials:

Use exponent law:

                   \(\boxed{\bf a^{m*n}=(a^m)^n} \ & \\\\\boxed{\bf a^m * b^m = (a*b)^m}\)

9x²y⁶ = 3²* x² * y³*² = 3² * x² * (y³)² = (3xy³)²

25x⁴y⁸ = 5² * x²*² * y⁴*² = 5² * (x²)² * (y⁴)² = (5x²y⁴)²

Now use the identity:  a² - b² = (a +b) (a -b)

Here, a = 3xy³ & b = 5x²y⁴

9x²y⁶ - 25x⁴y⁸ = 3²x²(y³)² - 5²(x²)² (y⁴)²

                       = (3xy³)² - (5x²y⁴)²

                      = (3xy³ + 5x²y⁴)  (3xy³ - 5x²y⁴)

The Value of x is 2/3.

The value of x, we need to determine the mean of the given values and set it equal to the expression for the mean.

The mean (average) is calculated by adding up all the values and dividing by the number of values. In this case, we have five values: x, x+3, x-5, 2x, and 3x.

Mean = (x + x+3 + x-5 + 2x + 3x) / 5

Next, we simplify the expression:

Mean = (5x - 2 + 3x) / 5

Mean = (8x - 2) / 5

We are given that the mean is also equal to x:

Mean = x

Setting these two expressions equal to each other, we have:

(x) = (8x - 2) / 5

To solve for x, we can cross-multiply:

5x = 8x - 2

Bringing all the x terms to one side of the equation and the constant terms to the other side:

5x - 8x = -2

-3x = -2

Dividing both sides by -3:

x = -2 / -3

Simplifying, we get:

x = 2/3

Therefore, the value of x is 2/3.
