Relational databases are heavily based on the mathematical concept of: Set Theory. The correct option is (A).

Relational databases are based on the principles of set theory, which deals with sets of elements and their relationships with each other. In a relational database, data is organized into tables, with each table representing a set of related data.

The tables are then related to each other through the use of keys, which allow for the establishment of relationships between different sets of data. The principles of set theory also govern the use of operations such as union, intersection, and difference, which can be used to manipulate the data in the tables.

Therefore, the mathematical concept of set theory is a fundamental part of the design and use of relational databases.

If you  deposit $5,000 in a savings account and will earn 6. 5% simple interest over the first 10 years, then will earn $3,250 in interest over the 10-year period

Simple interest is a type of interest that is calculated only on the principal amount of an investment, and not on any interest that has been earned previously. It is typically expressed as a percentage of the principal amount and is applied over a fixed period of time.

To calculate the interest earned on the account over the 10-year period, we can use the formula for simple interest:

Interest = Principal x Rate x Time

Here, the principal is $5,000, the interest rate is 6.5%, and the time is 10 years.

Plugging in the values, we get:

Interest = $5,000 x 0.065 x 10

Interest = $3,250

Answer:

6 men

Step-by-step explanation:

The maximum value of the objective function is 4 at the vertex (4, 0), and the minimum value is -8 at the vertex (0, -4). The optimal solutions for the given LP problem are Maximum: p = 4 at x = 4 and y = 0 and Minimum: p = -8 at x = 0 and y = -4.

Maximize and minimize p = x + 2y

subject to:

x + y ≥ 4

x + y ≤ 10

x - y ≤ 4

x - y ≥ -4

First, let's graph the feasible region defined by the given constraints:

Plotting the lines:

x + y = 4 (solid line)

x + y = 10 (solid line)

x - y = 4 (solid line)

x - y = -4 (solid line)

The feasible region is the area that satisfies all the constraints and is bounded by the lines on the graph.

Upon examining the feasible region, we can observe that it is a bounded region.

To find the optimal solution, we need to evaluate the objective function p = x + 2y at the vertices (corner points) of the feasible region.

Now, let's find the vertices of the feasible region by solving the intersection points of the lines:

1. Intersection of x + y = 4 and x + y = 10:

Subtracting the equations, we get 0 = 6, which is not possible. No intersection point exists for these lines.

2. Intersection of x + y = 4 and x - y = 4:

Adding the equations, we get 2x = 8, x = 4. Substituting x = 4 into x + y = 4, we get 4 + y = 4, y = 0. The first vertex is (4, 0).

3. Intersection of x - y = 4 and x - y = -4:

Adding the equations, we get 2x = 0, x = 0. Substituting x = 0 into x - y = 4, we get -y = 4, y = -4. The second vertex is (0, -4).

Now, we evaluate the objective function at each vertex:

p(4, 0) = 4 + 2(0) = 4

p(0, -4) = 0 + 2(-4) = -8

The maximum value of the objective function is 4 at the vertex (4, 0), and the minimum value is -8 at the vertex (0, -4).

Therefore, the optimal solutions for the given LP problem are Maximum: p = 4 at x = 4 and y = 0 and Minimum: p = -8 at x = 0 and y = -4.

Step-by-step explanation:

For a = 1 and m = 1 does f(x) have a horizontal asymptote at y = 2 and a vertical asymptote at x = 1.

To find the values of a and m that give the function f(x) a horizontal asymptote at y = 2 and a vertical asymptote at x = 1, we need to analyze the behavior of the function as x approaches 1 and as x goes to infinity.

When x approaches 1 from the left and right sides, the denominator of f(x) approaches 0, so there is a vertical asymptote at x = 1. To have a vertical asymptote at x = 1, the numerator of f(x) cannot approach 0 as x approaches 1, so m must be greater than or equal to 1.

When x goes to infinity or negative infinity, the function f(x) approaches 2, which means there is a horizontal asymptote at y = 2. To have a horizontal asymptote at y = 2, the degree of the numerator must be equal to or less than the degree of the denominator. The degree of the numerator is m, and the degree of the denominator is 1.

So, the values of a and m that give f(x) a horizontal asymptote at y = 2 and a vertical asymptote at x = 1 are:

a = 1, m = 1

Substituting a = 1 and m = 1 into f(x), we get:

f(x) = 2x/(x+1)

which has a vertical asymptote at x = 1 and a horizontal asymptote at y = 2.

Therefore, the answer is a = 1, m = 1. The other values of a and m do not give a vertical asymptote at x = 1 and/or a horizontal asymptote at y = 2.

Step-by-step explanation:

The equation that models the fish population after t years is P(t) = 5800 * 1.20^t.

To write an equation that models the fish population after t years, we can use the formula for exponential growth:

P(t) = P(0) * (1 + r)^t

Where:

P(t) represents the fish population after t years,

P(0) represents the initial fish population (5800 in this case),

r represents the growth rate as a decimal (20% = 0.20),

t represents the number of years.

Substituting the given values into the equation, we have:

P(t) = 5800 * (1 + 0.20)^t

Simplifying further:

P(t) = 5800 * 1.20^t

Therefore, the equation that models the fish population after t years is P(t) = 5800 * 1.20^t.

The standard deviation s given z = 3, a desired accuracy of 5%, a mean cycle time of 1.9, a sample size of 17, and (xi+x)2 = 0.1296 is approximately 0.10.

To calculate the standard deviation s, we need to use the formula: s = sqrt((xi+x)2/n-1), where xi is the deviation from the mean, x is the mean, and n is the sample size. First, we need to find xi, which is the square root of 0.1296 divided by n-1, or 0.1296/16 = 0.0081. Next, we find x, which is given as 1.9. Finally, we can use the formula to find s: s = sqrt(0.0081*17) = 0.10 (rounded to two decimal places).

The accuracy of 5% is not directly used in this calculation but is important for determining the confidence level of the standard deviation. The confidence interval is typically expressed as (x-bar ± t(s/√n)), where x-bar is the sample mean, t is the t-distribution value based on the desired confidence level and degrees of freedom, s is the sample standard deviation, and n is the sample size. In this case, we would need to know the desired confidence level and degrees of freedom to calculate the appropriate t-value.

comp a(b) is equal to comp(a) when the magnitude of vector a is equal to 1, or in other words, when vector a is a unit vector.

The dot product between two vectors, a and b, can be written as:

a · b = |a| |b| cos θ,

where |a| and |b| are the magnitudes of vectors a and b, and θ is the angle between them.

The projection of vector b onto vector a, denoted as comp a(b), can be calculated as:

comp a(b) = |b| cos θ.

Now, let's consider the circumstance where comp a(b) is equal to comp(a).

comp a(b) = comp(a)

|b| cos θ = |a| |b| cos θ.

To simplify the equation, we can divide both sides by |b|:

cos θ = |a| cos θ.

Since cos θ cannot be zero (as a and b are nonzero vectors), we can divide both sides by cos θ:

1 = |a|.

Answer:

b = 40

Step-by-step explanation:

You want your discriminant to be zero because then you have exactly one solution.

Solve b²-4ac = 0

=>

b² - 4·400 = 0

b = ±√1600

so b=±40

but f(-20) also has to be 0

so b=40 remains as the solution

Answer:

b = 40

Step-by-step explanation:

If x = - 20 is a zero of f(x) then f(- 20) = 0 , that is

(- 20)² - 20b + 400 = 0

400 - 20b + 400 = 0

800 - 20b = 0 ( subtract 800 from both sides )

- 20b = - 800 ( divide both sides by - 20 )

b = 40

We want to write an inequality that tells how much Hannah should walk this week. The inequality will be:

x ≥ (3 + 3/4) mi

We know that she already did walk 2 3/4 miles this week, and she wants to walk at least 6 1/2 miles.

So to reach that minimum, she needs to walk:

(6  1/2)mi - (2 + 3/4) mi = (3 + 3/4) mi

And she can walk that or more, so the inequality is:

x ≥ (3 + 3/4) mi
