The graph is below.

The area of the pre-images is 8 and the area of the image is 2.  The difference is 6 \(units^{2}\)

Step-by-step explanation:

Area of the large triangle

a = \(\frac{bxh}{2}\)  I am going to choose the vertical line to be the base because I can count the base to be 4 and the height straight up from the base to be 4.

a = \(\frac{4x4}{2}\) = 8

I found the base for the image in the same way

a = \(\frac{2x2}{2}\) 2

Helping in the name of Jesus.

From the triangle, the values of α  , β and Ф are 97⁰, 45⁰ and 38⁰

Recall that the sum of angles of a straight line is 180 degrees and the sum of angles of a triangle is 180 degrees also.

using the given properties of a triangle and angles,

We have that Y + β - 180  ( sum of angles on a straight line)

where β = 135 degrees

Y = 180-135

Y = 45⁰

Also, using the same properties,

α + <EAC = 180 (sum of <s of a straight line)

α + 83 = 180

α = 97⁰

Ф = 180 - (97 + 45)

Ф = 180 -  142

Ф = 38⁰

This means that 9% of the notebook is used in science.

This means that 91% of the notebook pages is remaining.

The population proportion who participated in voting (63%) is higher than the sample proportion from this survey (58.91%).

To determine whether the population proportion who participated in voting or the sample proportion from the survey is higher, we need to compare the percentages.

The population proportion who participated in voting is given as 63% of all registered voters.

This means that out of every 100 registered voters, 63 participated in voting.

In the survey of retired voters, 162 out of 275 participants voted. To calculate the sample proportion, we divide the number of retired voters who participated (162) by the total number of retired voters in the sample (275) and multiply by 100 to get a percentage.

Sample proportion = (162 / 275) \(\times\) 100 ≈ 58.91%, .

Comparing the population proportion (63%) with the sample proportion (58.91%), we can see that the population proportion who participated in voting (63%) is higher than the sample proportion from this survey (58.91%).

Therefore, based on the given data, the population proportion who participated in voting is higher than the sample proportion from this survey.

It's important to note that the sample proportion is an estimate based on the surveyed retired voters and may not perfectly represent the entire population of registered voters.

Answer:

(a + 8)(a + 1)

Step-by-step explanation:

We know that the first term is squared, so we can put it out like this:

a * a

The third term has to be separated so that the sum of the two factors is the coefficient of the second term, 9.

8 = 4 * 2 (does 4 +/- 2 = 9? nope, we can't use that)

8 = 8 * 1 (does 8+/- 1 = 9? yes, when 8 + 1)

So the factor is a + 8 and a + 1.

Put this together and (a+8)(a+1)

To determine the number of ways the museum can arrange 3 Picasso paintings out of the 7 available, you can use the combination formula.  The correct answer should be 35 ways to arrange the 3 Picasso paintings on the same wall.

A combination is used when the order of the elements does not matter. The formula is:
C(n, k) = n! / (k! * (n-k)!)
Where n represents the total number of paintings (7 in this case) and k represents the number of paintings to be arranged (3 in this case). Using the formula, you get:
C(7, 3) = 7! / (3! * (7-3)!)
C(7, 3) = 7! / (3! * 4!)
C(7, 3) = 5040 / (6 * 24)
C(7, 3) = 5040 / 144
C(7, 3) = 35
However, since none of the given options match this result, there might be a mistake in the options provided. The correct answer should be 35 ways to arrange the 3 Picasso paintings on the same wall.

A well-balanced long hair design should consider the proportional relationships between size, shape, texture, and color to create a harmonious and visually pleasing hairstyle that flatters the client's features and personal style.

When planning a well-balanced long hair design, it is important to consider the proportional relationships between size, shape, texture, and color. These four elements work together to create a harmonious and visually pleasing hairstyle.

Size refers to the overall scale of the hairstyle, which can range from small and delicate to large and voluminous. It's important to consider the size of the client's head and face, as well as the desired level of impact.

Shape refers to the outline or silhouette of the hairstyle, which can be angular or rounded, symmetrical or asymmetrical. The shape should be chosen to flatter the client's face shape and features, as well as to create a balanced overall look.

Texture refers to the surface quality of the hair, which can be smooth or rough, sleek or tousled. Texture can be used to add interest and movement to the hairstyle, and should be chosen to complement the client's natural hair texture and the overall design.

Color refers to the hue, saturation, and tone of the hair, which can range from natural to bold and vibrant. Color can be used to enhance the shape and texture of the hairstyle, and should be chosen to flatter the client's skin tone and personal style.

In summary, a well-balanced long hair design should consider the proportional relationships between size, shape, texture, and color to create a harmonious and visually pleasing hairstyle that flatters the client's features and personal style.

Answer:

f(x)=x^3 - 13x^2 + 40x + 17

Step-by-step explanation:

x-0=0    x-5=0       x-8=0

  x=0        x=5           x=8

y=x(x-5)(x-8)+b  ==> b is what's going to be used to find the equation so that

                                y=17 when x=0

17=0(0-5)(0-8)+b  ==> plugin 0 for x and 17 for y

17=0*(-5)*(-8)+b  ==> simplify

17=0+b  ==> anything multiplied by 0 is 0.

b=17  

Hence, the equation is:

y=x(x-5)(x-8)+17  ==> expand this equation

y=x*(x-5)(x-8) + 17

y=x*(x(x - 8) - 5(x - 8)) + 17  ==> distribute x-8 to x and -5

y=x*(x*x - 8x - 5x - (8)(-5)) + 17  ==> distribution property

y=x*(x^2 - 13x - (-40)) + 17   ==> simplify

y=x*(x^2 - 13x + 40) + 17  ==> subtracting a negative number is equivalent to

                                              adding a positive number

y=x^3 - 13x^2 + 40x + 17 ==> multiply x with x^2, 13x, and 40 using the

                                              distribution property.

Answer: f(x)=x^3 - 13x^2 + 40x + 17

Answer: Okay, lets explain.

Step-by-step explanation:Since 0, 5 & 8 are given as the zeros of the required 3rd degree polynomial f(x), therefore, one may take it as ; f(x) =k (x-0)(x-5)(x-8)

= k(x³−13x²+40) …. .. .(1) . Since f(10) = 17 (given), it implies 17 = k(1000 -1300 + 400) = 100 ==> k = 17/100 = 0.17 . Put this value of k in eq(1) and get the required polynomial.

Answer:

Let's call the cost of a blouse "b" (in dollars). Then, according to the problem, the cost of a dress is 3/4 of the cost of a blouse, or (3/4)b.

We know that Vicky paid $350 for 3 dresses and 4 blouses, so we can set up the equation:

3(3/4)b + 4b = 350

Simplifying this equation, we get:

9/4 b + 4b = 350

Combining like terms, we get:

17/4 b = 350

To solve for b, we can multiply both sides by 4/17:

b = 350 × 4/17 = $82.35 (rounded to two decimal places)

Therefore, the cost of a dress is:

(3/4)b = (3/4)($82.35) = $61.76 (rounded to two decimal places)

So each dress cost $61.76.

The enrollment at East Valley High School over a six-year period is displayed in the scatterplot. Student Enrollment at East Valley High School (1st picture)

Which is the equation of the line of best-fit for this scatterplot? (2nd picture)

Answer:

D) y = (81/2)x - (160,069/2)

Step-by-step Explanation:

From the scatter plot in the graph attached below, we are given the ordered pairs of the coordinates (2009, 1330), (2013, 1492), we can derive the equation of the line of best-fit for the scatter plot using the slope-intercept formula.

Thus, the slope-intercept formula is y = mx + b, where m is the slope of the line; and b is the y-intercept.

We need to find m, and then b to input into the formula to get our equation of the line.

==> Finding m using the two sets of coordinate given on the graph [ (2009, 1330) and (2013, 1492) ]:

slope (m) = (y2 - y1)/(x2 - x1)

m = (1492 - 1330)/(2013 - 2009)

= 162/4

m = 81/2

Next is to find b, which is the y-intercept

Recall, y = mx + b

Using one of the coordinates given (2009, 1330), we can find b by inputting 1330 for y, 2009 for x, and 81/2 for m in the slope-intercept formula:

Thus, we would have ==>

1330 = (81/2 * 2009) + b

1330 = (162,729/2) + b

1330 - 162,729/2 = b

(2,660 - 162,729)/2 = b

- 160,069/2 = b

Having known the values of m, and b, let's input their values to get the equation of the line.

Thus, using the slope-intercept formula y = mx + b, the equation of the line of best-fit for the scatter plot would be

==> y = (81/2)x +(-160,069/2)

y = (81/2)x - (160,069/2)

Step-by-step explanation:

Straight-line graphs are commonly referred to as "linear graphs" or "linear equations."

We have,

A straight line graph, often referred to as a linear graph or linear equation, represents a relationship between two variables that can be expressed by a linear equation in the form y = mx + b.

In this equation, 'x' and 'y' are the variables, 'm' is the slope of the line, and 'b' is the y-intercept (the point where the line crosses the y-axis).

The slope 'm' determines the steepness or incline of the line.

A positive slope indicates the line rises as 'x' increases, while a negative slope indicates the line descends as 'x' increases.

The y-intercept 'b' represents the value of 'y' when 'x' is zero, determining where the line crosses the y-axis.

Thus,

Straight line graphs are commonly referred to as "linear graphs" or "linear equations.

Step-by-step explanation:

the answer is 2046

The population of fish first exceed the capacity of the lake will be 2046. Then the correct option is C.

Let b is the base and x is the power of the exponent function and a is the leading coefficient. The exponent is given as

y = a(b)ˣ

The population of a certain fish species can be modeled using the equation

\(\rm P(t)= 50 \ e^{0.15t}\)

where t is the number of years after 2018.

A particular lake can accommodate at most 3,500 of this fish species.

Based on the model, the year in which population of fish first exceed the capacity of the lake 3,500 will be

\(\rm 3500= 50 \ e^{0.15t}\\\\70 \ \ \ = e^{0.15t}\)

Taking log on both sides, we have

ln 70 = 0.15t ln e

4.248 = 0.15 t

t = 28.32 ≈ 28 years

Then the year will be

⇒ 2018 + 28

⇒ 2046

The population of fish first exceed the capacity of the lake will be 2046.

Then the correct option is C.
