a) A function f is a rule that assigns to each element x in a set A exactly one element called f(x) in a set B.
b) Both tables define y as a function of x, but they have different domains and ranges
Both tables represent functions because they assign each value of x in the domain to a unique value of y in the range.
First table
f(1) = 5
f(2) = 7
f(3) = 6
f(4) = 8
Second table
f(1) = 5
f(2) = 1
f(3) = 7
f(4) = 6
f(5) = 8
So both tables define y as a function of x, but they have different domains and ranges. The first table has a domain of {1, 2, 3, 4} and a range of {5, 6, 7, 8}, while the second table has a domain of {1, 2, 3, 4, 5} and a range of {1, 5, 6, 7, 8}.

An airship traveled 150 km with the wind and then turns around and flies back, taking 6h and 15 min for the round trip. Find the speed of the wind if the speed of the airship in calm weather is 50 km/hour.
Let's call the speed of the wind "w". When the airship is flying with the wind, its effective speed is 50 + w km/hour. When the airship is flying against the wind, its effective speed is 50 - w km/hour.
Using the formula distance = rate x time, we can write two equations for the round trip:
150 = (50 + w)(t1)
150 = (50 - w)(t2)
where t1 is the time the airship took to fly with the wind and t2 is the time it took to fly against the wind.
We also know that the total round trip took 6 hours and 15 minutes, or 6.25 hours:
t1 + t2 = 6.25
Now we can solve for w. Let's rearrange the second equation to solve for t2:
t2 = 150 / (50 - w)
Substitute this expression for t2 into the third equation:
t1 + 150 / (50 - w) = 6.25
Solve for t1:
t1 = 6.25 - 150 / (50 - w)
Now substitute this expression for t1 into the first equation:
150 = (50 + w)(6.25 - 150 / (50 - w))
Simplify and solve for w:
w = 25 km/hour
Therefore, the speed of the wind is 25 km/hour.
There is a light pole that casts a shadow that is 75 feet. At the same time, there is a stop sign that is 8 feet tall and casts a shadow that is 12 feet. How tall is the light pole? If necessary, round your answer to the nearest tenth.
Answer: Therefore, the height of the light pole is 50 feet.
Step-by-step explanation:
We can use proportions to solve the problem.
Let h be the height of the light pole.
Then, we have:
h / 75 = 8 / 12
To solve for h, we can cross-multiply:
12h = 75 * 8
h = (75 * 8) / 12
h = 50
Find the value of k such that the line through (6, 4) and (k,2) is parallel to the line y=2x .
the value of k such that the line through (6, 4) and (k, 2) is parallel to the line y = 2x is k = 5.
How to solve the question ?
To find the value of k such that the line through (6, 4) and (k, 2) is parallel to the line y = 2x, we need to find the slope of the line y = 2x, which is 2.
Since two lines are parallel if and only if they have the same slope, we know that the line through (6, 4) and (k, 2) must also have a slope of 2.
Using the slope formula:
slope = (y₂ - y₁) / (x₂ - x₁)
where (x₁, y₁) = (6, 4) and (x₂, y₂) = (k, 2), we get:
2 = (2 - 4) / (k - 6)
Multiplying both sides by k - 6 gives:
2(k - 6) = -2
Expanding and simplifying gives:
2k - 12 = -2
Adding 12 to both sides gives:
2k = 10
Dividing both sides by 2 gives:
k = 5
Therefore, the value of k such that the line through (6, 4) and (k, 2) is parallel to the line y = 2x is k = 5.

(a) Find the intervals on which f is increasing or decreasing. (b) Find the local maximum and minimum values of f. (c) Find the intervals of concavity and inflection points.
f(x)= x^4-2x^2+3
Part (c) is where I'm having issues on how to derive the second derivative f'(x)=4x(x-1)(x+1)
can you please show all steps.
The inflection points are at x = -[tex]\sqrt{(1/3)}[/tex] and x = sqrt(1/3), and f is concave up on (-[tex]\sqrt{1/3}[/tex]), [tex]\sqrt{(1/3)}[/tex]), and concave down elsewhere.
(a) To find the intervals on which f is increasing or decreasing, we need to find the first derivative of f and determine its sign.
[tex]f(x) = x^4 - 2x^2 + 3[/tex]
[tex]f'(x) = 4x^3 - 4x[/tex]
Setting f'(x) = 0, we get:
[tex]4x(x^2 - 1) = 0[/tex]
This equation has roots at x = 0, x = -1, and x = 1. We can use the first derivative test to determine the intervals of increasing and decreasing.
When x < -1, f'(x) is negative, so f is decreasing.
When -1 < x < 0, f'(x) is positive, so f is increasing.
When 0 < x < 1, f'(x) is negative, so f is decreasing.
When x > 1, f'(x) is positive, so f is increasing.
Therefore, f is decreasing on (-∞, -1) and (0, 1), and increasing on (-1, 0) and (1, ∞).
(b) To find the local maximum and minimum values of f, we need to look for critical points and evaluate the function at those points.
Critical points occur where f'(x) = 0 or is undefined. We have already found that f'(x) = 0 at x = 0, x = -1, and x = 1.
f(0) = 3, f(-1) = 6, f(1) = 2
Therefore, f has a local maximum at x = -1, with a value of 6, and local minimums at x = 0 and x = 1, with values of 3 and 2, respectively.
(c) To find the intervals of concavity and inflection points, we need to find the second derivative of f and determine its sign.
[tex]f(x) = x^4 - 2x^2 + 3[/tex]
[tex]f'(x) = 4x^3 - 4x[/tex]
[tex]f''(x) = 12x^2 - 4[/tex]
Setting f''(x) = 0, we get:
[tex]12x^2 - 4 = 0[/tex]
[tex]x^2 = 1/3[/tex]
x = ±sqrt(1/3)
We can use the second derivative test to determine the intervals of concavity.
When x < -sqrt(1/3), f''(x) is negative, so f is concave down.
When -sqrt(1/3) < x < sqrt(1/3), f''(x) is positive, so f is concave up.
When x > sqrt(1/3), f''(x) is negative, so f is concave down.
Therefore, the inflection points are at x = -sqrt(1/3) and x = sqrt(1/3), and f is concave up on (-sqrt(1/3), sqrt(1/3)), and concave down elsewhere.

Company revenue quadratic function.
Angel
The revenue, in billions of dollars, for a company in the year 2002 was $2.7 billion. One year later, in 2003, the revenue had risen to $3.4 billion. In 2005, the revenue climbed to $3.9 billion, before falling to $2.7 billion in 2008. The revenue, r, in billions of dollars, for the company, is a quadratic function of the number of years since 2002, x. what is the vertex of the function?
To find the quadratic function that represents the revenue of the company as a function of the number of years since 2002, we can use the vertex form of a quadratic function:
r(x) = a(x - h)^2 + k
where a is the coefficient of the quadratic term, h is the x-coordinate of the vertex, and k is the y-coordinate of the vertex.
We can use the given revenue values to set up a system of three equations:
2.7 = a(0 - h)^2 + k
3.4 = a(1 - h)^2 + k
2.7 = a(6 - h)^2 + k
Subtracting the first equation from the second, and the first equation from the third, we get:
0.7 = a(1 - h)^2
0 = a(6 - h)^2
Since a cannot be zero (otherwise we wouldn't have a quadratic function), we can divide the second equation by the first to get:
6 - h = 10
which gives us h = -4.
Substituting h = -4 into the first equation, we get:
2.7 = a(0 - (-4))^2 + k
2.7 = 16a + k
Substituting the revenue value for 2005, we get:
3.9 = a(3 - (-4))^2 + k
3.9 = 49a + k
Solving for a and k, we get:
a = -0.1
k = 4.3
Therefore, the quadratic function that represents the revenue of the company as a function of the number of years since 2002 is:
r(x) = -0.1(x + 4)^2 + 4.3
The vertex of this function is at (-4, 4.3).

What is the sum of the numbers in the sequence 3, −4, 5, −6, . . . , 101?
We can notice that the sequence alternates between adding an odd number and subtracting an even number. The first term is 3, which is odd, so the sequence starts by adding an odd number. The second term is -4, which is even, so the sequence then subtracts an even number. This pattern continues, so the sum of the sequence can be written as:
3 - 4 + 5 - 6 + ... + 101
We can group the terms into pairs:
(3 - 4) + (5 - 6) + ... + (99 - 100) + 101
Each pair of terms adds up to -1, so we can simplify the expression to:
-1 -1 -1 ... -1 + 101
where there are 50 pairs of -1's. The sum of 50 -1's is -50, so the sum of the sequence is:
-50 + 101 = 51
Therefore, the sum of the numbers in the sequence 3, −4, 5, −6, . . . , 101 is 51.

What is 12 7/8 - 56/17?
To subtract mixed numbers like 12 7/8, we first need to convert it to an improper fraction. We can do this by multiplying the whole number by the denominator of the fraction, and adding the result to the numerator. This gives us:
12 7/8 = (12 × 8 + 7)/8 = 103/8
Now we can subtract 56/17 from 103/8. To do this, we need to find a common denominator for the two fractions. The least common multiple of 8 and 17 is 136, so we can rewrite the fractions with this denominator:
103/8 = (103/8) × (17/17) = 1751/136
56/17 = (56/17) × (8/8) = 448/136
Now we can subtract the two fractions:
1751/136 - 448/136 = (1751 - 448)/136 = 1303/136
We can simplify this fraction by finding a common factor to divide both the numerator and denominator. Since both 1303 and 136 are relatively prime, we cannot simplify it any further. Therefore, the final answer is:
12 7/8 - 56/17 = 1303/136

For the rectangle shaped drawing, the area of the scale drawing is 31.25 cm².
What exactly is a rectangle?
A rectangle is a four-sided flat form with four right angles on its four sides (90-degree angles). It is a quadrilateral having two pairs of equal-length parallel sides. A rectangle's perimeter is the total of the lengths of all four sides, and its area is derived by multiplying the rectangle's length and breadth. A square is a specific instance of a rectangle with four equal-length sides.
Now,
To find the perimeter of the scale drawing, we add the lengths of all four sides. Rounded to the nearest half centimeter, the length is 12.5 cm and the width is 2.5 cm, so the perimeter is:
P = 2(12.5 cm) + 2(2.5 cm) = 25 cm + 5 cm = 30 cm
Therefore, the perimeter of the scale drawing is 30 centimeters.
To find the area of the scale drawing, we multiply the length by the width. Rounded to the nearest half centimeter, the length is 12.5 cm and the width is 2.5 cm, so the area is:
A = (12.5 cm) × (2.5 cm) = 31.25 cm²
Therefore, the area of the scale drawing is 31.25 square centimeters.

40% of the people in a town are females. 10% of the females are left -handed. 20. 8% of all the people are left -handed. Work out the percentage of the people who are not female who are left -handed
Answer:
16.8%
Step-by-step explanation:
When fourty percentage of the people in a town are females. 10% of the females are left -handed. Then total 16.8% of peoples in the town are not female and are left-handed.
We have a percentage data of people in a town. Percentage of female peoples in the town = 40 %
Percentage of female left handed = 10 %
Percentage of total left handed = 20.8 %
Percentage is defined as a ratio of a number to 100 or it expressed as a fraction of 100. Let Total population of the town = X
So, female peoples in the town = 40% of X = (40/100) × X
= 0.4X
The peoples who are not female = X - 0.4X = 0.96X
Number of female left-handed = 10% of 0.4X = (10/100)× 0.4X
= 0.04X
Number of all left-handed in the town
= 20.8% of X = (208/100)× X
= 0.208X
Left-handed peoples who are not female
= 0.208X - 0.04X
= 0.168X
The percentage of people who are not female and who are left-handed
= (0.168X /X )×100
= 16.8%
Hence, required percentage is 16.8%.

Rashaad leans a 16-foot ladder against a wall so that it forms an angle of 66° with the ground. what's the horizontal distance between the base of the ladder and the wall?
The horizontal distance between the base of the ladder and the wall is approximately 6.58 feet
We can use trigonometric function to solve this problem. Let's call the horizontal distance we are looking for "x".
First, we can use the fact that the ladder forms an angle of 66° with the ground to find the vertical height it reaches. We know that the ladder is 16 feet long, and we can use the sine function to find the vertical height
sin(66°) = height/16
height = 16×sin(66°) = 15.12 feet (rounded to two decimal places)
Now, we can use the same angle and the cosine function to find the horizontal distance x
cos(66°) = x/16
x = 16×cos(66°) = 6.58 feet (rounded to two decimal places)

(-4,2) and (3,-3) what’s the slope
Answer:
7 over -5
Step-by-step explanation:
For what value of the constant c is the following function a probability density function? f(x) = cx^3, (0 < x < 1).
The value of the constant c such that the function f(x) = cx³ is a probability density function is 4.
The given function is f(x) = cx³, where 0 < x < 1. We know that a function f(x) is said to be a probability density function on the interval [a, b] if it satisfies the following conditions: 1. f(x) ≥ 0 for all x ∈ [a, b].2. ∫f(x)dx = 1 over the interval [a, b]. Given that 0 < x < 1, the limits of integration are from 0 to 1.
Now, integrating the given function, we get: ∫₀¹ cx³ dx= [c/4 x⁴]₀¹= c/4 × 1⁴ - c/4 × 0⁴= c/4
Therefore, for the given function to be a probability density function, the value of c should be such that∫₀¹ cx³ dx = 1⇒ c/4 = 1⇒ c = 4

as the set designer for his school's fall play, kenji is making a treasure chest shaped like a rectangular prism. the chest needs to hold approximately 6 cubic feet, or 10,368 cubic inches, of sand that will be spilled out during the first act. also, since an actor will stand on the chest in the second act, the chest needs to be 24 inches tall. kenji decides that the chest will be twice as long as it is wide. to the nearest tenth of an inch, what is the width of the chest?
The width of the chest shaped like a rectangular prism, to the nearest tenth of an inch is 32.1.
Kenji has made a treasure chest, shaped like a rectangular prism that must hold around 10,368 cubic inches of sand. In the second act of the school play, an actor will stand on the chest.
Therefore, the chest must be 24 inches tall. The length of the chest is twice its width.
To determine the width of the chest, you should first determine the length of the chest.
Then, using the formula for the volume of a rectangular prism, you can solve for the width of the chest.
Length of the chest
The formula for the volume of a rectangular prism is V = lwh
Given that the chest needs to hold around 10,368 cubic inches of sand, we can write 10,368 = lwh
Since the chest is twice as long as it is wide, the length (l) of the chest is equal to 2w.
Substituting 2w for l, we have:
10,368 = (2w)w
hence 5,184 = wh²(5,184/h)
= w*h(5,184/h²) = w
Since the chest must also be 24 inches tall, we can write:
h = 24 feet
Substituting this value into the equation, we have:
(5,184/24²) = w
hence w = 32.1 inches
Therefore, the width of the chest to the nearest tenth of an inch is 32.1 inches.

The Smith family is planning to put an above a ground swimming pool in their back
yard. Their yard is a 25 ft by 60 ft and the pool will be a circle with a DIAMETER of
16 ft, as shown below. They will fill the rest of the yard with grass. Find out how many
square feet of their yard will be grass?
Enter your answer with two digits for the decimals
60 ft.
16 ft.
25 ft.
PLEASE HELP
Answer:
The first step is to calculate the area of the circle pool:
- The diameter of the pool is 16 ft, which means the radius is 8 ft (half of the diameter).
- The formula for the area of a circle is A = πr^2, where A is the area and r is the radius.
- Plugging in the values, we get A = π(8 ft)^2 = 64π sq ft.
The total area of the yard is 25 ft x 60 ft = 1500 sq ft. To find out how many square feet of the yard will be grass, we need to subtract the area of the pool from the total area of the yard:
- Grass area = Total area - Pool area = 1500 sq ft - 64π sq ft ≈ 1304.43 sq ft.
Therefore, about 1304.43 square feet of their yard will be grass, to two decimal places.

The measures of the angles of a triangle are shown in the figure below. Solve for x.
36°
(6x+3)°
87°
Answer:
Step-by-step explanation:The sum of the measures of the angles in a triangle is always 180 degrees. So, we can set up an equation and solve for x:
36 + (6x+3) + 87 = 180
Combine like terms:
126 + 6x = 180
Subtract 126 from both sides:
6x = 54
Divide both sides by 6:
x = 9
Therefore, the value of x is 9.
