Answer:

Part 1) The price will decrease $5,548

Part 2) The price of the next model is $32,452

Step-by-step explanation:

Let

x ----> the price of the next model

we know that

The current model costs $38,000 -----> represent the 100%

step 1

To find the price decrease in dollars multiply the current model price by 14.6%

14.6%=14.6/100=0.146

so

0.146*($38,000)= $5,548

step 2

Find the price of the next model

To find the price of the next model subtract the price decrease from the price of the current model

so

x=$38,000-$5,548=$32,452

Answer:

The order pair of point Q' is (-21/4 , -7/2)

Step-by-step explanation:

* Lets explain the dilation

- A dilation is a transformation that changes the size of a figure.  

- The figure can become larger or smaller, but the shape of the

 figure does not change.  

- The scale factor, measures how much the image will be larger

 or smaller  

- If the scale factor greater than 1, then the image will be larger

- If the scale factor between 0 and 1, then the image will be smaller

- The center of dilation is a fixed point in the plane about which all

 points are expanded or contracted

* Lets solve the problem

- The pentagon OPQRS is dilated by a scale factor 7/4

- The center of dilation is the origin

- The image of the pentagon after the dilation is O'P'Q'R'S'

∵ The coordinates of the vertices of the pentagon OPQRS are

  O (-1 , 2) , P (-5 , 3) , Q (-3 , -2) , R (2 , 1) , S (2 , 5)

- To find the image of each point after the dilation multiply each

  coordinates of the points by the scale factor of dilation

∵ The scale factor is 7/4

∵ The coordinates of point Q are (-3 , -2)

∴ The image of point Q after dilation is (-3 × 7/4 , -2 × 7/4)

∴ The image of point Q after dilation is (-21/4 , -7/2)

∵ Q' is the image of Q

∴ Q' = (-21/4 , -7/2)

* The order pair of point Q' is (-21/4 , -7/2)

Answer:

Step-by-step explanation:

{z+1}/{z-1} = i.

z+1 = i (z-1)

z+1 =iz -i

z - iz  = -1 -i

z ( 1 -i) = - 1 -i

z = (- 1 - i ) /(1-i) = - (1+i)/(1-i)

z = - (1+i)(1+i)/(1-i)(1+i)

z = - (1+2i +i²)/ ( 1²-i²).........i² = -1

z =-2i/2

z = - i      (one solution)

All the complex numbers z satisfying the equation {z+1}/{z-1} = i is z = -i.

Complex numbers are numbers which are of the form [tex]a + ib[/tex], where a and b are real numbers and i is the imaginary number called iota whose value is [tex]i^2[/tex]= -1.

Given equation is,

(z + 1) / (z - 1) = i

Multiplying both sides by (z - 1),

z + 1 = i (z - 1)

Let z = (a + bi)

Substituting,

(a + bi + 1) = i (a + bi - 1)

(a + bi + 1) - i (a + bi - 1) = 0

a + bi + 1 - (ai + b(i)² - i) = 0

a + bi + 1 - ai - b(i)² + i = 0

Now i² = -1

a + bi + 1 - ai + b + i = 0

Combining the like terms,

(bi - ai + i) + (a + 1 + b) = 0

i (b - a + 1) + (a + b + 1) = 0

Left hand side is a complex number.

A complex number is a + bi = 0, when a = 0 and b = 0.

So, we get,

(b - a + 1) = 0 and (a + b + 1) = 0

b - a = -1 and a + b = -1

So, combining,

a + b = b - a

a + a = b - b

2a = 0

a = 0

Substituting,

b = -1

So the complex number, z = a + bi = -i

Hence the complex number z = -i.

[tex]P=0.4125[/tex]

Step-by-step explanation:

In this case we have a uniform probability. In the graph the horizontal axis represents the possible values of the variable x and the vertical axis represents the probability P(x).

To calculate the probability that x is between 4.71 and 7.4 we calculate the area under the curve.

The horizontal length between 4.71 and 7.4 is:

[tex]7.4-4.1 = 3.3[/tex].

Then notice that the vertical length in this interval is 0.125.

Then the area of a rectangle is:

[tex]A = lw[/tex]

Where l is the length and w is the width.

In this case we have to:

[tex]l = 3.3[/tex]

[tex]w = 0.125[/tex]

So

[tex]P = A = 3.3 * 0.125[/tex]

Answer:

The translation is right 4 units and up 4 units

Step-by-step explanation:

we know that

The rule of the translation of the point V to V' is equal to

(x,y) ----> (x+4,y+4)

That means ----> The translation is right 4 units and up 4 units

Verify

V(-2,3) -----> V'(-2+4,3+4)

V(-2,3) -----> V'(2,7)

Is correct

The true statement is: The transformation is a vertical translation. (Statement 3)

Let's analyze each statement:

1. The point moves two units up and four units to the right.

  - This statement is incorrect. The point moves four units up, not two units up.

2. The transformation rule is (x, y) → (x + 0, y + 4).

  - This statement is incorrect. The transformation rule should be (x, y) → (x, y + 4) because the point moves vertically by adding 4 to the y-coordinate.

3. The transformation is a vertical translation.

  - This statement is correct. The point moves vertically, changing only the y-coordinate.

4. The image is four units to the right of the pre-image.

  - This statement is incorrect. The image is at the same x-coordinate as the pre-image (-2), so it's not four units to the right.

5. The translation can be described as (x, y) → (x - 2, y + 7).

  - This statement is incorrect. The translation rule should be (x, y) → (x, y + 4) because the point only moves vertically.

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, - 3) and (x₂, y₂ ) = (- 7, 4)

m = [tex]\frac{4+3}{-7+2}[/tex] = [tex]\frac{7}{-5}[/tex] = - [tex]\frac{7}{5}[/tex]

We can use either of the 2 points for (a, b)

Using (a, b) = (- 7, 4), then

y - 4 = -[tex]\frac{7}{5}[/tex](x - (- 7)), that is

y - 4 = - [tex]\frac{7}{5}[/tex](x + 7) ← in point- slope form

[tex]y = \frac{1}{2}x+\frac{5}{2}[/tex]

Step-by-step explanation:

The perpendicular bisector of a line passes through the mid-point of the line and the product of slopes of the line and perpendicular bisector will be -1.

So,

[tex]Mid-point\ of\ BC = (\frac{6+8}{2},  \frac{8+4}{2})\\= (\frac{14}{2},  \frac{12}{2})\\= (7,6)[/tex]

The line will pass through (7,6)

Now,

[tex]Slope\ of\ BC = m_1 = \frac{y_2-y_1}{x_2-x_1} \\=\frac{4-8}{8-6}\\= \frac{-4}{2}\\= -2[/tex]

Let

So,

m_1*m_2 = -1

-2 * m_2 = -1

m_2 = -1/-2 = 1/2

The standard equation of line is:

y=mx+b

Where m is slope

So putting the value of slope and point to find the value of b

[tex]\left \{ {{5x+2y=-8} \atop {x+4y=2}} \right.[/tex]

I'll be solving this system of equations using the elimination method since the x and y values are neatly lined up.

I want to get a pair of x's or y's that cancel out, and it looks like the easiest way to start would be by multiplying the first equation by -2 (the y's will cancel).

I chose to multiply the first equation by -2 instead of multiplying the second equation by 5 because -2 is a smaller number and easier to multiply by.

[tex]-2\times(5x+2y=-8)[/tex]

Distribute -2 inside the parentheses. Now you've got:

[tex]\left \{ {{-10x-4y=16} \atop {x+4y=2}} \right.[/tex]

Add up the equations from top to bottom.

-10x plus x is -9x, the -4y and 4y cancel out, and 16 plus 2 is 18. Make this one single equation.

[tex]-9x=18[/tex]

Divide both sides by -9.

[tex]x=-2[/tex]

Substitute this value of x into the second equation (less to do with the x since it has no coefficient which means no multiplying).

[tex](-2)+4y=2[/tex]

Add 2 to both sides.

[tex]4y=4[/tex]

Divide both sides by 4.

[tex]y=1[/tex]

The final answer is [tex]x=-2, ~y=1[/tex].

Answer:

C. positively skewed

Step-by-step explanation:

If a data set has more extremely large data values, the distribution is said to be positively skewed.

Have a great day!

A data set with more extremely large data values is said to be skewed right or positively skewed. This describes a distribution where the tail on the right side is extended due to a few high extreme values.

If a data set has more extremely large data values, the distribution is said to be skewed right or positively skewed. This occurs because the tail of the distribution on the right-hand side is longer or more drawn out compared to the left-hand side.

In a right-skewed distribution, the mean is typically larger than the median, and the mode lies to the left of the median. This asymmetry indicates a larger number of lower values and a few extreme higher values in the data set. For example, if we have a data set with the histogram showing a longer tail on the right, it suggests there are some very large values stretching the scale, resulting in a skewed right distribution.

y =8x-32.50

Answer:

see explanation

Step-by-step explanation:

Given that y varies inversely as x then the equation relating them is

y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation

To find k use the condition x = 2.5 when y = 100

k = yx = 100 × 2.5 = 250

y = [tex]\frac{250}{x}[/tex] ← equation of variation

The constant of variation (k) in the inverse relationship equation (y = k/x) can be determined by multiplying the x and y values provided. In this case, k = 250. Therefore, the equation of variation would be y = 250 / x.

Given the inverse relationship where y varies inversely with x, it follows the general equation of y = k/x. This relationship is provided by the constant of variation (k). It can be determined by multiplying the given x and y values.

In this case, x = 2.5 when y = 100. We substitute these into our inverse relationship equation, yielding 100 = k/2.5. By multiplying both sides by 2.5, we are able to find that k = 250. Therefore, the equation of variation would be y = 250/x.

just a quick note, that triangle is misleading some, since the HG side of 6 units, shows longer than GE which is 8, and of course 8 > 6.

Since GE is a perpendicular bisector, that means the angle at G is 90°.

Check the picture below.

To find the length of HE, we utilize the properties of a perpendicular bisector and trigonometry. Knowing that GE halves HF into two equal parts, we calculate HF using trigonometric concepts, then halve it to find HE.

In the question, it's mentioned that GE is a perpendicular bisector of HF. This means that GE bisects HF into two equal lengths. Therefore, the length of HE will be equivalent to half of the length of HF.

Since, HF can be calculated using trigonometry as mentioned. By definition, cose = x/h, so if we know the height 'h' and the angle, we can find 'x' which in this case would be HF, and subsequently HE would be HF/2.

Moreover, in trigonometry, the length of side opposite to the right angle in a right-angled triangle is calculated by the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. We use this to find out HF if other two sides are known.
