Given the problem:
Explain what are the figure below functions or not
The left graph is not a function, the right table is a function. To see if a graph is a function, use the vertical line test. Simply draw vertical lines down the graph, or you don't have to if you can imagine it. None of the vertical lines can pass through any points twice. So in this case, look at (6, 4) and (6, 6). Draw a vertical line down at x=6. It fails the vertical line test because the vertical line passes through the two points.
Next, the table on the right. It is a function. To determine whether a table is a function or not, look at the x values. No x value can duplicate. In this case, all x values are different.
Hope this helped.

Answers
The cumulative frequency distribution table is present below. Cumulative frequency for speed less than 30 is 4 , less than 60 is 20 , less than 90 is 80 less than 120 is 100. So, correct answer is option (b).
The cumulative frequency of a variable's value is the number of values in the collection of data that are less than or equal to the variable's value. Example: Let the raw data be 2, 2, 1, 5, 5, 6, 5, 3, 7, 7, 5, 6. Cumulative frequency of 3 = 4. Cumulative frequency is a frequency distribution table for the predecessor total. The final value is always equal to the sum of all observations, since all frequencies have already been added to the previous sum. We have a data corresponds to the frequencydistribution.
Speed Number of cars
0-29 4
30-59 16
60-89 60
90-119 20
We have to construct the cumulative frequency distribution for the above frequency distribution.Using the above rules we can construct distribution as,
Speed Number of cars Cumulative Freq
0-29 4 4
30-59 16 16 + 4 = 20
60-89 60 60 + 20= 80
90-119 20 20 + 80 = 100
-----------
Total 100
Thus , cumulative frequency for speed less than 30 is 4 , less than 60 is 20 , less than 90 is 80
less than 120 is 100.
Hence, we got the required cumulative frequencies for frequency distribution.

A manufacturer wants to make open tin boxes from pieces of tin with dimensions 8 in. by 15 in. by cutting equal squares fromthe four corners and turning up the sides. Find the side of the square cutout that gives the box the largest possible volume.
a) 0 in.
b) 6 in.
c) 5/3 in.
d) 2450/27 in.
Answers
The side of the square cutout that gives the box the largest possible volume
Therefore the answer is d) 2450/27 in.
To find the side length of the square cutouts that give the box the largest volume, we need to find an expression for the volume of the box in terms of the side length of the square cutouts. We can start by subtracting four times the area of one square cutout from the total area of the tin sheet to find the area of the box sides. The volume of the box will then be equal to the area of the box sides multiplied by the height.
The side length of the square cutouts can be represented by x. The area of one square cutout is x^2, so the total area of the four cutouts is
4x^2
The area of the tin sheet is 8 * 15 = 120. The area of the box sides is then
120 - 4x^2
The volume of the box is then (120 - 4x^2) * 8, which we want to maximize. To do this, we can differentiate the expression for the volume with respect to x and set it equal to zero, then solve for x. The solution to this optimization problem is
x = 2450/27, which is the side length of the square cutouts that gives the box the largest volume.

What is Bernoulli differential equation?
A Bernoulli differential equation is a type of non-linear ordinary differential equation of the form:
dy/dx + P(x)y = Q(x)yⁿ
where P(x) and Q(x) are functions of x and n is a constant. The equation is named after the Swiss mathematician Jakob Bernoulli.
These types of differential equations are important in various fields of science, such as physics, engineering, and economics. They are non-linear, meaning that the dependent variable y appears in both linear and non-linear terms, making them difficult to solve in general.
a) This differential equation can be written in the form (*) with P(x) = x, Q(x) = 2x, and n = 2.
b) The substitution u = y⁻¹ will transform it into the linear equation du/dx - xu = -2x.

Systematic sampling is a form of probability sampling approach in which sample members are drawn from a larger population at random but with a set, periodic interval.
The sampling interval is determined by dividing the population size by the desired sample size.
Systematic sampling is a technique for picking a sample from a larger population at regular intervals. In this scenario, the library manager selects a sample of library users by tallying the number of persons every 28th day.

To simplify the expression (2x + 8)^6, we need to raise the binomial (2x + 8) to the power of 6. This can be done using the binomial theorem.
The Binomial Theorem states that for any positive integer n and real numbers a and b, the expansion of the expression (a + b)^n is a sum of terms of the form (a^(n-k) * b^k * C(n,k)), where C(n,k) represents the binomial coefficient, which is equal to n!/(k!(n-k)!).
[tex](a + b)^n = C(n, 0)a^n b^0 + C(n, 1)a^(n-1) b^1 + ... + C(n, n-1)a^1 b^(n-1) + C(n, n)a^0 b^n[/tex]
Where C(n, k) is the binomial coefficient, given by C(n, k) = n! / (k! (n - k)!).
In this case, a = 2x and b = 8. So, substituting these values into the binomial theorem:
[tex](2x + 8)^6 = C(6, 0)(2x)^6 8^0 + C(6, 1)(2x)^5 8^1 + ... + C(6, 5)(2x)^1 8^5 + C(6, 6)(2x)^0 8^6[/tex]
Expanding each term, and combining like terms, we get:

A sector of a circle has an area of 20 square feet. Find the central angle which forms the sector if the radius is 5 feet. The central angle of the sector isradians. (Type an integer or a simplified fraction.)
Answers
The area of a sector of a circle is equal to the central angle multiplied by the radius squared, divided by 2. In this case, the sector of the circle has an area of 20 square feet, the radius is 5 feet, and we need to find the central angle.
The central angle will be 6.28 radians.
To find the central angle, we can rearrange the equation to solve for the angle:
Central Angle = (2 * Area) / (Radius^2)
Substituting the given values, we get:
Central Angle = (2 * 20) / (5^2)
Simplifying, we find that the Central Angle equals 6.28 radians.
