Step-by-step explanation:
The graph below is the function f(x)
Find lim x -> -1- f(x)=
As x approaches -1 from the left, the graph of f(x) leads you to the point (-1, 3), so the limit from the left is 3.
As x approaches -1 from the right, the graph leads to the point (-1, -3), so the limit from the right is -3.
The one-sided limits do not match, so the two-sided limit does not exist.
But f(x) is still defined at x = -1; this is indicated by the point (-1, -1). So f (-1) = -1.
We have found all the given limits for all the function.

Tammy bought 16 cookies for a party. She had 6 cookies decorated at an extra cost of 25 cents each. If the total cost of the cookies was $9.50, how much did each plain cookie cost?
[ACCURATE ANSWER FOR BRAINLIEST]
Answer:
one plain cookie costs $0.50Step-by-step explanation:
so 25 x 6 is the extra cost
150 cents is the extra cost
subtract that from 9.50
you are left with $8
now we know that 16 plan cookies cost $8
so one plain cookie costs $0.50
Answer:
.50c
Step-by-step explanation:
1) You take the cost of the extra cookies and subtract from the total so 6 * .25 = 1.50 then 9.50 - 1.50 = 8.00
2) you take the 8.00 then divide it by the total number of cookies which is 8.00 ÷ 16 = 0.50
What the meaning of "f is order-preserving if x < y implies f(x) < f(y)"?
An order-preserving function is a function that preserves the order of its inputs. In other words, if x is less than y, then f(x) will be less than f(y).
The statement "f is order-preserving if x < y implies f(x) < f(y)" means that if x is less than y, then f(x) must be less than f(y). This is a necessary condition for a function to be order-preserving. However, it is not a sufficient condition. For example, the function f(x) = x^2 is not order-preserving, because 2 < 3, but f(2) = 4 > f(3) = 9.
In summary, order-preserving functions are useful in situations where we need to preserve the order of a set of data.

3 6 9 12 15 18 21 24 27 30 is odd or even numbers?
Answer: Half of them are even and half of them are odd.
Step-by-step explanation:
The even numbers are 6, 12, 18, 24, and 30. An even number is defined as a number that is divisible by 2, meaning it has no remainder when divided by 2. For example, 6 divided by 2 equals 3 with no remainder, so 6 is even.
The odd numbers are 3, 9, 15, 21, and 27. An odd number is defined as a number that is not divisible by 2, meaning it has a remainder of 1 when divided by 2. For example, 9 divided by 2 equals 4 with a remainder of 1, so 9 is odd.
Therefore, out of the given numbers, half of them are even and half of them are odd.

The growth rate function indicates that the number of years The Iron Man's net worth will reach the net worth of T'Challa is about 87 years
What is a growth rate?The growth rate is the rate of growth of a function with regards to the input variable.
T'Challa's net worth in the Marvel comics = 80 trillion (8 × 10¹³) Dollars
The Iron Man's net worth = 20 billion (2 × 10¹⁰) Dollars
The growth rate per annum of The Iron Man's net worth = 10% per annum
The number of years it will take to reach T'Challa can therefore, be found as follows;;
(2 × 10¹⁰) × (1 + 0.1)ˣ = (8 × 10¹³)
(1 + 0.1)ˣ = (8 × 10¹³)/(2 × 10¹⁰)
x·ln(1 + 0.1) = ln((8 × 10¹³)/(2 × 10¹⁰))
x = (ln((8 × 10¹³)/(2 × 10¹⁰)))/(ln(1 + 0.1)) ≈ 87 years

Which graph represents the function f(x)=4x?

Answer:
slope = 4
points on graph = (0,0), (1,4)
Step-by-step explanation:
line going through quadrants 1 and 3. Straight line.
write an equation in slope intercept form that passes through the given point and is perpendicular to the graph of given equation (1,-2) y=5x+4
The equation of the line perpendicular to y = 5x + 4, passing through the point (1, -2), is y = (-1/5)x - 9/5.
To find an equation in slope-intercept form that passes through the point (1, -2) and is perpendicular to the given equation y = 5x + 4, we need to determine the slope of the perpendicular line.
The given equation y = 5x + 4 is already in slope-intercept form (y = mx + b), where m represents the slope. In this case, the slope of the given line is 5.
To find the slope of a line perpendicular to this, we use the fact that the product of the slopes of two perpendicular lines is -1. So, the slope of the perpendicular line can be found by taking the negative reciprocal of the slope of the given line.
The negative reciprocal of 5 is -1/5.
Now that we have the slope (-1/5) and a point (1, -2), we can use the point-slope form of the equation:
y - y1 = m(x - x1)
Substituting the values:
y - (-2) = (-1/5)(x - 1)
Simplifying:
y + 2 = (-1/5)(x - 1)
To convert the equation into slope-intercept form (y = mx + b), we need to simplify it further:
y + 2 = (-1/5)x + 1/5
Subtracting 2 from both sides:
y = (-1/5)x + 1/5 - 2
Combining the constants:
y = (-1/5)x - 9/5
Therefore, the equation of the line perpendicular to y = 5x + 4, passing through the point (1, -2), is y = (-1/5)x - 9/5.

The side of a triangle are in the ratio 4:4:3 what kind of triangle is it (b) calculate the smallest angle of the triangle to the nearest degree
The smallest angle of the equilateral triangle is 60 degrees
If the sides of a triangle are in the ratio 4:4:3, it implies that the lengths of the sides are proportional.
To determine the type of triangle, we examine the side lengths. Since all three sides are equal in length, we have an equilateral triangle.
For an equilateral triangle, all angles are equal. To calculate the smallest angle, we divide the total sum of angles in a triangle (180 degrees) by the number of angles, which is 3:
Smallest angle \(= \frac{180}{3} = 60\)\) degrees.
Therefore, the smallest angle of the equilateral triangle is 60 degrees (to the nearest degree).

So, the earning increased by about 4.28%.
Employee A gets paid $150 weekly, plus $0.50 for each latte they sell. If he was paid $275,how many lattes did he sell this week?
Let x be the number of latter he sold this week
Let us first set the equation
y = 0.5x + 150 where y is the total pay
275 = 0.5x + 150
Let's go ahead and solve for x
substract 150 from both-side
275 - 150 = 0.50x
125 = 0.50x
Divide both-side by 0.50
250 =x
Hence, he sold 250 lattes

The solution to the system of linear equations is (x, y, z) = (64/11, 37/11, 9/11). The system has exactly one solution.
Let's solve the system of linear equations correctly.
The given system of linear equations is:
x = y + 3z = 6
x - 2y = 5
2x - 2y + 5z = 9
To determine the number of solutions, we can analyze the system using the method of elimination or substitution. Let's use the method of elimination:
From equation 1, we have:
x = y + 3z
Substituting this value of x in equation 2:
(y + 3z) - 2y = 5
y + 3z - 2y = 5
-z + 3z = 5 - y
2z = 5 - y
Now, let's substitute the value of x in equation 3:
2(y + 3z) - 2y + 5z = 9
2y + 6z - 2y + 5z = 9
11z = 9
Simplifying the equation, we find:
z = 9/11
Now, substituting this value of z back into the equation 2z = 5 - y, we get:
2(9/11) = 5 - y
18/11 = 5 - y
18/11 - 5 = -y
18/11 - 55/11 = -y
-37/11 = -y
y = 37/11
Finally, we can substitute the values of y and z into equation 1 to find the value of x:
x = y + 3z
x = 37/11 + 3(9/11)
x = 37/11 + 27/11
x = 64/11
Therefore, the solution to the system of linear equations is (x, y, z) = (64/11, 37/11, 9/11).
The system has exactly one solution.

The triangles are similar because of the :
A) AA Similarity postulate
B) SSS similarity theorem
C) SAS similarity theorem
D) The triangles are not similar
Answer:
A) AA Similarity postulate
Step-by-step explanation:
You want to know why two right triangles are similar when one has an acute angle marked 50°, and the other has an acute angle marked 40°.
Missing anglesIn each right triangle, the missing angle is the complement of the one shown.
In ∆XYZ, missing angle X is the complement of angle Y:
X = 90° -Y = 90° -50° = 40°
The angles X, Y, Z are 40°, 50°, 90°.
In ∆ABC, missing angle B is the complement of angle A:
B = 90° -A = 90° -40° = 50°
The angles A, B, C are 40°, 50°, 90°.
The angles in the two triangles have the same measures, so the triangles are similar because of the AA similarity postulate.
__
Additional comment
Once you have found one of the missing angles, you have two angles to match to two angles in the other triangle. It is not necessary to find the measures of all of the angles.
The similarity statement would be written ∆XYZ ~ ∆ABC.
For Mean = 73.19, Mode = 79.56 and Variance = 16, the Karl Pearson's Coefficient of Skewness will be -0.0256 -1.64 0.0256 0
Answer:
To calculate Karl Pearson's coefficient of skewness, we need to use the formula:
Skewness = 3 * (Mean - Mode) / Standard Deviation
Given the Mean = 73.19, Mode = 79.56, and Variance = 16, we need to find the Standard Deviation first.
Standard Deviation = √Variance = √16 = 4
Now we can substitute the values into the formula:
Skewness = 3 * (73.19 - 79.56) / 4
Skewness = -6.37 / 4
Skewness = -1.5925
Rounded to four decimal places, the Karl Pearson's coefficient of skewness for the given values is approximately -1.5925.
