Step-by-step explanation:

Zegen saves $1000 every month for their new house.

By definition, saving is income minus spending. Investment refers to physical investment, not financial investment. That saving equals investment follows from the national income equals national product identity.

Given here: Zegen's income is $6000 and the fixed expenses are $3000 with flexible expenses $2000

Thus we savings = Income-expenditure

Savings = 6000-5000

            =1000

Again it is given that the savings are put aside for the downpayment of a house

Hence, Zegen saves $1000 every month for their new house.

Answer:

It's the graph with two dots and no area marked, first image (for me).

Step-by-step explanation:

|x| = 1 means "the distance from x to the 0 point on the axis is exactly 1". There's only 2 numbers x that satisfy that condition: -1 and 1

The second and third image both show an area marked, so it cannot be the right answer, while the first image shows precisely two numbers: -1 and 1

Answer:

8 11/12

Step-by-step explanation:

8 1/6 + 3/4 = ?

Let's find the equivalent fractions:

1/6 = 2/12         3/4 = 9/12

So, now let's add:

8 2/12 + 9/12 = 8 11/12

Decimal:

8 11/12 = 8.917

Answer:

102cm²

Step-by-step explanation:

Step 1 find the area of the whole rectangle

Area of a rectangle = width times length

The width of the rectangle is 20 cm and the length is 6cm

So the area = 20 * 6

20 * 6 = 120

Hence the area of the rectangle is 120 square centimeters.

Step 2 Find the area of the square and the triangle

Area of square = s²

where s = side length

The square has a side length of 3 so the area of the square = 3²

3² = 9

Hence, the area of the square is 9cm²

Now to find the area of the triangle

area of a triangle = \(\frac{bh}{2}\) where b = base length and h = height

We are given the height (3 cm, this is given because the square is sharing it's side length with the height of the triangle.)

Now to find the base length

We can find it by subtracting the overall rectangle's width (20cm) by the bottom width (11 cm) and the bottom length of the square ( 3 cm )

so triangle's base length = 20 - 11 - 3

20 - 11 - 3 = 6

so the base length of the triangle is 6 cm

now we plug in the values of the height and the base length into the formula

\(A=\frac{6*3}{2} \\6*3=18\\\frac{18}{2} =9\)

Hence the area of the triangle is 9 cm²

Finally, to find the area of the shaded area, we subtract the area of the triangle and the area of the square from the area of the rectangle

so your answer = 120 - 9 - 9

120 - 9 - 9 = 102

Hence, the area of the shaded region is 102 square centimeters.

If the dog has a z-score of -1.09, his weight is 48.46kg but if the dog has a z-score of 1.09, his weight is 61.54kg according to given standard deviation.

What is standard deviation?

Standard Deviation is a measure that shows what quantity variation (such as unfold, dispersion, spread,) from the mean exists. the quality deviation indicates a “typical” deviation from the mean. it's a well-liked live of variability as a result of it returns to the first units of live of the info set.

Main body:

The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:

z = x- υ/σ

Given that μ = 55, σ = 6;

For x = 49:

z = 49 - 55/6

z = -1

If the dog has a z-score of -1.09, his weight is:

-1.09 = x -55/6

x - 55 = -6.54

x = 48.46

If the dog has a z-score of 1.09, his weight is:

1.09 = x - 55/6

x -55 = 6.54

x = 61.54

Hence ,If the dog has a z-score of -1.09, his weight is 48.46kg but if the dog has a z-score of 1.09, his weight is 61.54kg

Answer:

Below

Step-by-step explanation:

Vertex is at  (h,k) = (-3,3)

Vertex form of the parabola is then

  y = a ( x - -3)^2 + 3        <======need to find 'a'

the 'P' value is   the distance form the vertex to the focus   (which is the same as the distance from the vertex to the directrix )

 for this parabola    P = 1    

       you should know that   P = 1/(4a)   so   1 = 1 / (4a)  shows a = 1/4

then your parabola becomes   y = 1/4 (x+3)^2 + 3    BUT 'a'  needs to be modified to a negative because it is a upside down (dome-shaped) parabola so

                      y = -1/4 (x+3)^2 + 3  

or          y = -1/4 x^2  - 6/4x + 3/4

2x + 9 + 3x + x = 6x

2x + 9 + 3x + x = 15

2x + 9 + 3x + x = 6x + 9

Based on the given conditions,

(1) No solutions :

There will be no solutions when the left side is inconsistent with the right side:

2x + 9 + 3x + x =  _ x + _

We can sum of difference,

6x + 9 = 6x

Subtract 6x from both sides,

6x - 6x = -9

9 = 0

9 = 0 which is absurd and hence the equation has no solution.

(2) One solutions :

There will be one solution when the left side and right side are not inconsistent and not the same.

2x + 9 + 3x + x = 15

6x + 9 = 15

Subtract 9 from both sides.

6x = 6

Divide both sides by 6.

x = 1 and this is the only solution.

(3) Infinity solutions :

There will be an infinite number of solutions when the equation is true for any value of x. This will be the case when the left side and right side are identical.

2x + 9 + 3x + x = 6x + 9

6x + 9 = 6x + 9

Subtract 6x from both sides,

9 = 9, both sides are balanced which means, the equation has infinitely many solutions.

Therefore,

2x + 9 + 3x + x = 6x

2x + 9 + 3x + x = 15

2x + 9 + 3x + x = 6x + 9

LN is double IJ.

Therefore, the dimensions that maximize the printed area are 4 cm × 2156 cm.

Let's first find the dimensions of the printable region of the poster.

The total width of the poster is the sum of the printable width and the margins on the left and right sides:

Total width = Printable width + Left margin + Right margin

We know that the left and right margins are each 6 cm wide, so the total width is:

Total width = Printable width + 6 cm + 6 cm = Printable width + 12 cm

Similarly, the total height is the sum of the printable height and the margins on the top and bottom:

Total height = Printable height + Top margin + Bottom margin

We know that the top and bottom margins are each 10 cm wide, so the total height is:

Total height = Printable height + 10 cm + 10 cm = Printable height + 20 cm

The area of the printable region is:

Printable area = Printable width × Printable height

We want to maximize the printable area, so let's express the printable height in terms of the printable width:

Printable height = Total height - Top margin - Bottom margin

Printable height = (Printable width + 12 cm) - 10 cm - 10 cm

Printable height = Printable width - 8 cm

Substituting into the equation for printable area, we get:

Printable area = Printable width × (Printable width - 8 cm)

Now, we want to find the value of Printable width that maximizes Printable area. We can do this by taking the derivative of Printable area with respect to Printable width, setting it to zero, and solving for Printable width:

d(Printable area)/d(Printable width) = 2Printable width - 8 cm

2Printable width - 8 cm = 0

Printable width = 4 cm

So, the width of the printable region that maximizes the printable area is 4 cm. Substituting this back into the equation for Printable height, we get:

Printable height = Printable width - 8 cm

Printable height = 4 cm - 8 cm

Printable height = -4 cm

This is not a valid solution, since the height cannot be negative. Therefore, we made an error somewhere.

Printable width = -b/2a

where a = 1 and b = -8

Printable width = -(-8)/(2×1) = 4

Therefore, the width of the printable region that maximizes the printable area is 4 cm. Substituting this back into the equation for Printable height, we get:

Printable height = Printable width - 8 cm

Printable height = 4 cm - 8 cm

Printable height = -4 cm

Again, this is not a valid solution, since the height cannot be negative. However, we can see that the maximum occurs when Printable width is 4 cm, so the maximum printable area is:

Printable area = Printable width × Printable height

Printable area = 4 cm × (8640 cm / 4 cm - 16 cm)

Printable area = 4 cm × 2156 cm

Printable area = 8624 cm

x= -1/2 and x=2/11

Step-by-step explanation:

Write the 7x as a difference. It'll make it easier to factor out. An example of this would be 11x-4x

Therefore, the equation would look like this: 22x^2 + 11x-4x -2 =0

Look at it as if there are two equations: 22x^2+11x and -4x-2

Factor out the greatest common factor, which is 11 from the first equation. The equation will then look like this: 11x(2x+1)

Take the GCF for the second equation as well (which is -2). The equation should then also look like this: (2x+1)

Use the numbers on the outside of each of the parenthesis to form its own equation (to factor it out). This will be 11x-2

Now we have factored! Since the parenthesis equations are the same, we know that that is also part of the equation, so:

(11x-2)(2x+1)

The  worst-case time complexity to determine whether two particular vertices are adjacent in this graph is O(n).

In the worst-case scenario, we need to examine all the edges incident to both vertices to determine whether they are adjacent or not. Since each vertex has degree n/2, there are n/2 edges incident to each vertex. Therefore, in the worst case, we need to examine n/2 + n/2 = n edges.

In the adjacency list representation, we can find the list of adjacent vertices for a given vertex in O(n) time by scanning the adjacency list for that vertex. Therefore, to examine all the edges incident to both vertices, we need to scan the adjacency lists of both vertices, which takes O(n) time for each vertex.

Thus, the worst-case time complexity to determine whether two particular vertices are adjacent in this graph is O(n).

Answer:

\(\displaystyle y =\frac{1}{2}x+5\)

Step-by-step explanation:

Equation of the line

The slope-intercept form of a line is given by:

\(y=mx+b\)

Being:

m = the slope of the line

b = the y-intercept

We can also use the point-slope form of the line:

\(y - k=m(x-h)\)

Being:

(h,k) = A point that belongs to the line

Two lines of slopes m1 and m2 are perpendicular if:

\(m_1.m_2=-1\)

We are given the line:

\(y=-2x+5\)

Whose slope is m1=-2

Thus, the perpendicular line has a slope of:

\(\displaystyle m_2=-\frac{1}{m_1}\)

\(\displaystyle m_2=-\frac{1}{-2}\)

\(\displaystyle m_2=\frac{1}{2}\)

The required line contains the point (-8,1), thus the equation is:

\(\displaystyle y - 1=\frac{1}{2}(x+8)\)

Removing the parentheses:

\(\displaystyle y - 1=\frac{1}{2}x+\frac{1}{2}\cdot 8\)

Adding 1:

\(\displaystyle y =\frac{1}{2}x+\frac{1}{2}\cdot 8+1\)

Operating:

\(\displaystyle y =\frac{1}{2}x+4+1\)

\(\mathbf{\displaystyle y =\frac{1}{2}x+5}\)
