The continuous functions at x = -4 are given as follows:

The function is continuous when it has these two features:

For the definitions in this problem, we have that:

For the first two functions, the function can be simplified as follows:

(x² - 16)/(x + 4) = [(x - 4)(x + 4)]/(x + 4) = x - 4.

Hence the limit at x = -4 is given as follows:

-4 - 4 = -8.

Meaning that the second function is continuous at x = -4.

For the last two functions, the function can be simplified as follows:

(x² + 8x + 16)/(x + 4) = (x + 4)²/(x + 4) = x + 4.

Hence the limit at x = -4 is given as follows:

-4 + 4 = 4.

Meaning that the fourth and last function is also continuous at x = -4.

Step-by-step explanation:

The required expected crime when income decreases by 1000 is 50.

In property crime, a victim's property is taken or obliterated, without the utilization or danger of power against the person in question. Local misdemeanors incorporate thievery and robbery as well as defacing and incendiary.

We have,

crime = 428 + 0. 050 income

If the income goes down by 1, crime goes down by 0.050.

Similarity, if income goes down by 1000, crime goes sown by 0.050(1000)

⇒ 50

Thus, the expected crime is 50.

Given that the client requested a permanent haircut, there is a 66.66% chance that he would request a haircut.

The following calculation must be performed in order to determine the probability that a randomly selected client requested a haircut given that he has requested a permanent: Given that a salon owner noted what types of services its clients requested last week, the results showed that 5% requested dye only, 30% haircut and dye, 35% requested haircut only, 10% hair cut and permanent, 5% permanent only, and 15% other.

Add all of the options that include a perm, and then use a cross multiplication to figure out how many of those options include a haircut.

10 (permanent and haircut) x 5 (permanent only) = 15 15 = 100 10 = X 10 x 100/15 = 66.66 = X

Slope is a measure of how much a line changes in the y-direction for every unit of change in the x-direction. It is typically represented by the m in the equation y = mx + b. Line through points -5, -10, and -1 has a slope of 5.

Slope is calculated by taking the difference in the y-coordinates divided by the difference in the x-coordinates of two points on a line. Since we only have one point, we cannot calculate the slope .The slope of a line is equal to the change in y divided by the change in x. We can calculate the slope by subtracting the y-coordinates and then dividing by the difference of the x-coordinates. In this case, the change in y is (10 - (-5)) = 15 and the change in x is (5 - (-1)) = 6. Therefore, the slope of the line is 15/6 = 5.

The slope intercept form of equation of required line is y = 3x + 9

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If  [tex]\theta[/tex] is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m =  [tex]tan\theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

Here,

Slope = 3

The line passes through (8, 33)

Equation of required line

y - 33 = 3(x - 8)

y - 33 = 3x - 24

y = 3x - 24 + 33

The probability that the same number appears twice is 0.16

What is probability?

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.

The fair die is thrown twice.

The total number of outcomes if a fair die is tossed twice is 36.

The favorable number of outcomes, which also contains six, is six.

Following is a calculation of the likelihood of the same number appearing twice.

Probability = (Number of possible outcomes)/(Total number of outcomes)

                  = 6/36

                  = 0.16

Step-by-step explanation:

Since the ΔEFG is similar to ΔHIJ, so side HI is equivalent to the measure of length of segment [EF] divided by the scale factor [K].

        equilateral triangle, scalene triangle, isosceles triangle etc.

We have triangle ΔEFG is similar to triangle ΔHIJ.

Since ΔEFG is similar to triangle ΔHIJ, then we can write -

EF/HI = FG/IJ = EG/HJ = K [constant]

Since the side lengths are not given, we can write -

EF/HI = K

HI = EF/K

The length of the rectangle is 6m - 2.

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

Area = 30m² - 20m - 10

Width = 5m - 5

Now,

Area = Length x Width

30m² - 20m - 10 = Length x (5m - 5)

10(3m² - 2m - 1) = Length x (5m - 5)

10(3m² - (3 - 1)m - 1 = Length x (5m - 5)

10 (3m² - 3m + m - 1) = Length x (5m - 5)

10 (3m(m - 1) + 1(m - 1)) = Length x (5m - 5)

10 (3m + 1)(m - 1) = Length x 5(m - 1)

(m - 1) gets canceled.

To solve the equation y = -5/2x - 7, we can first multiply both sides of the equation by 2x + 7, which is the denominator of the fraction on the right-hand side. This gives us the equation 2xy + 7y = -5, which we can rearrange to isolate the variable y on one side of the equation. Dividing both sides of the equation by 2x + 7, we get y = -5 / (2x + 7). This is the solution to the original equation.

The vertex of the function g(x)=-2x²- 14x +12 is (-7/2, 25/2).

A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .

The given function is g(x)=-2x²- 14x +12

We need to find the vertex of the function.

y=-2x²- 14x +12

To make it a perfect square we are adding and subtracting (7/2)²

y=-2x²- 14x +(7/2)²+12-49/4

y=-2(x+7/2)²+25/2

x+7/2=0

Subtract 7/2 on both sides

x=-7/2

and y=25/2

The Poster Dimensions of rectangle will be:

W = 18 inches

Y = 36 inches

Area can be defined as the amount of space covered by a plane of a particular shape. It is measured in "number" of square units (square centimeters, square inches, square feet, etc.). The area of ​​a rectangle is the number of unit squares that fit in the rectangle. Examples of rectangles are flat surfaces such as laptop monitors, chalkboards, and painting canvases. You can use the rectangle area formula to find the space occupied by these objects.

Now,

Let's say the printable area of ​​a rectangular poster is 512 square inches

"x". " and "y" - the dimensions of the printed area of ​​the poster

A(p) = printed area of ​​the poster = x × y

512 = x × y ⇒ y = 512/x

Therefore, The total area of ​​the poster is:

A( t) = ( y + 4 ) ×  ( x + 2 )

⇒ A(t) = yx +2y +4x + 8 and y = 512/x

Total Area of x or Total poster area as x function:

   A(x) =( 512/x)*x + 2* (512/x) + 4*x + 8

   A(x) = 512 + 1024/x + 4 *x + 8

⇒ A(x) = 520 + 1024/x + 4*x

Differentiating both sides of the equation gives:

     A´(x) = - 1024/x² + 4

     A´(x) = 0

⇒ - 1024 /x² = -4

⇒  4*x² = 1024

⇒ x² = 1024/4

⇒ x² = 256

or, x = 16 inches

and y = 512/x

⇒ y = 512/16

⇒ y = 32 inches

So x is found, the y dimension of the print area, Than n is the dimension of the poster:

Therefore,

w = x + 2 ⇒ w = 16 + 2 w = 18 in

And,

Y = y + 4 ⇒ Y = 32 + 4 Y = 36 in

A equation is supposed to be linear equation in two factors in the event that it is written as ax + by + c=0, where a, b and c are genuine numbers and the coefficients of x and y, i.e an and b separately, are not equivalent to nothing. For instance, 10x+4y = 3 and - x+5y = 2 are direct conditions in two factors.

Let x be the pound of Bolivian coffee and y is that of Colombian coffee.

Bolivian coffee sells for $4.59 per pound, and Colombian coffee sells for $5.95 per pound and whole mixture sells for $5.10.

So,  4.59x + 5.95y = 5.10(4000)

The amount of money lost per year is 15x

Where 100x can be any amount

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Let the total amount of money earned in a year from the field = 100x

The new field area.

= 100% - 15%

= 85%

Now,

The amount of money earned in a year from the new field area.

= 85% of 100x
