The feasible set for this system of constraints is not convex, and the points (5, 5) and (3, 7) violate the convexity definition.

To determine whether the feasible set for each system of constraints is convex, we need to analyze the constraints individually and examine their intersection.

a) (x1)² + (x2)² > 9

This constraint represents points outside the circle with a radius of √9 = 3. The feasible set includes all points outside this circle.

b) x1 + x2 ≤ 10

This constraint represents points that lie on or below the line x1 + x2 = 10. The feasible set includes all points on or below this line.

c) x1, x2 > 0

This constraint represents points in the positive quadrant, where both x1 and x2 are greater than zero.

Now, let's analyze the intersection of these constraints:

Considering the first two constraints (a and b), we can see that the feasible set consists of all points outside the circle (constraint a) and below or on the line x1 + x2 = 10 (constraint b).

To determine whether the feasible set is convex, we need to check if any two points within the set create a line segment that lies entirely within the set.

If we consider the points (5, 5) and (3, 7), both points satisfy the individual constraints (a) and (b). However, the line segment connecting these two points, which is the line segment between (5, 5) and (3, 7), exits the feasible set since it passes through the circle (constraint a) and above the line x1 + x2 = 10 (constraint b).

Therefore, the feasible set for this system of constraints is not convex, and the points (5, 5) and (3, 7) violate the convexity definition.

Step-by-step explanation:

The Laplace transform of g(t) is equal to 1/(s-2)e^(-2s) + 3/(s^2+9)e^(-πs).

The Laplace transform of a function can be found by applying the definition of the Laplace transform. Let's find the Laplace transform of the function g(t) = e^(2t)U(t-2) + sin(3t)U(t-π) step by step.
1. The Laplace transform of e^(at)U(t-c) is given by L{e^(at)U(t-c)} = 1/(s-a)e^(-cs), where s is the complex variable.
2. Applying this formula, we can find the Laplace transform of the first term, e^(2t)U(t-2):
  L{e^(2t)U(t-2)} = 1/(s-2)e^(-2s)
3. Similarly, the Laplace transform of the second term, sin(3t)U(t-π), can be found using the formula for the Laplace transform of sin(at)U(t-c):
  L{sin(3t)U(t-π)} = 3/(s^2+9)e^(-πs)
4. Finally, we can combine the two transformed terms:
  L{g(t)} = L{e^(2t)U(t-2)} + L{sin(3t)U(t-π)}
         = 1/(s-2)e^(-2s) + 3/(s^2+9)e^(-πs)
Therefore, the Laplace transform of g(t) is equal to 1/(s-2)e^(-2s) + 3/(s^2+9)e^(-πs).

The relation 2 represents a function.

In order to determine which relation in the below table represents a function, we need to first understand what a function is.A function is a relationship in which each input value corresponds to exactly one output value.

To put it another way, each x-value has one and only one y-value. The most typical method to determine whether a relation is a function is to use the vertical line test.

The vertical line test is a way to determine if a relation is a function graphically. To test if a graph is a function, we draw a vertical line through each x-value on the graph. If a vertical line crosses the graph more than once, it is not a function.

If, on the other hand, the graph passes the vertical line test and no vertical line crosses the graph more than once, it is a function.Now let's look at the table below to determine which relation is a function.

We will first plot the x and y values of each relation on a coordinate system and then apply the vertical line test to each relation.

Relation 1: x | y0 | 10 | 11 | 22 | 23 | 34 | 35 | 4Relation 1 does not represent a function since we can draw a vertical line through x = 3 and the line will cross the graph more than once.

Relation 2: x | y2 | 33 | 34 | 45 | 46 | 57 | 5Relation 2 represents a function since we can draw a vertical line through each x-value on the graph and it will only cross the graph once.

6a) In(x' √y") can be written in terms of u and v as In(√(e^v/e^u))

b) For function f(x)=In(x-7), the domain of f(x) is x > 7, the x-intercept is x = 8, a vertical asymptote at x = 7

7) The amplitude is 7, period is 2π/9 and the phase shift is -7/9 for function y=7sin (9x + 7)

(a) To write In(x' √y") in terms of u and v, we can first express x' and √y" in terms of x and y using the definitions of u and v.

Recall that u = ln(x) and v = ln(y).

To express x' in terms of x, we can differentiate u with respect to x:

du/dx = 1/x

Similarly, to express √y" in terms of y, we can differentiate v with respectto y:

dv/dy = 1/y

Now, let's rewrite the expression In(x' √y") using u and v:

In(x' √y") = In(du/dx √(dv/dy))

Since du/dx = 1/x and dv/dy = 1/y, we have:

In(x' √y") = In(1/x √(1/y))

Using the properties of logarithms, we can simplify further:

In(x' √y") = In(√(y/x))

Therefore, In(x' √y") can be written in terms of u and v as In(√(e^v/e^u)).

b) For the function f(x) = In(x - 7):

Domain: The natural logarithm function is defined for positive real numbers, so the domain of f(x) is x > 7.

X-intercept: To find the x-intercept, we set f(x) = 0 and solve for x:

In(x - 7) = 0

x - 7 = 1

x = 8

So the x-intercept is x = 8.

Asymptotes: The function f(x) = In(x - 7) does not have any vertical asymptotes.

However, it has a vertical asymptote at x = 7 because the natural logarithm is not defined for x - 7 ≤ 0.

7. For the function y = 7sin(9x + 7):

Amplitude: The amplitude of a sine function is the absolute value of the coefficient of the sine term.

In this case, the amplitude is |7| = 7.

Period: The period of a sine function is given by the formula T = 2π/b, where b is the coefficient of the variable x inside the sine term.

In this case, the coefficient is 9, so the period is T = 2π/9.

Phase shift: The phase shift of a sine function is given by the formula -c/b, where c is the constant term inside the sine term.

In this case, the constant term is 7, so the phase shift is -7/9.

A invested for approximately 5 months.

Hence, the answer is not among the options provided.

We are given the investment ratio between partners A and B, which is 6:7. This means that for every 6 units of investment by A, B invests 7 units.

Next, we are given the profit sharing ratio, which is 2:1. This means that out of the total profit, 2 parts are given to A and 1 part is given to B.

Now, we are told that partner B invested for 3 months. Let's assume that partner A invested for 'x' months.

Since the profit sharing ratio is 2:1, and partner B invested for 3 months, partner A's investment must be spread over a period where the ratio of their investments remains the same.

Using the concept of proportions, we can set up the following equation:

(6/7) / (x/3) = 2/1

Cross-multiplying, we have:

2(6/7) = (x/3) * 1

12/7 = x/3

To solve for x, we can cross-multiply again:

7x = 12 * 3

7x = 36

Dividing both sides by 7, we get:

x = 36/7 ≈ 5.1428

Since we are dealing with months, we round this value to the nearest whole number. Therefore, A invested for approximately 5 months.

Hence, the answer is not among the options provided.

Answer:

6 yds

Step-by-step explanation:

If we label the shorter side as x, the longer side can be represented as 2x + 2. Now, we can write an equation to model the situation. The area of a rectangle is the sides multiplied by each other:

84 = x(2x + 2)

84 = 2x^2 + 2x

Since all terms are divisible by two, we can divide both sides by it:

42 = x^2 + x

We can write the quadratic equation in standard form:

x^2 + x - 42 = 0

Now, we can factor. We are looking for numbers that multiply to -42 and add to 1. These numbers are 7 and -6. Factored the equation would be written as followed:

(x + 7)(x - 6) = 0

Using the zero-product property, we can obtain two equations and solve them:

x + 7 = 0

x  = -7

x - 6 = 0

x = 6

Since the side of a rectangle can't be negative, the answer must be 6 yds.

Based on the information given, we have:

P(A) = 0.46

P(B) = 0.17

P(A U B) = 0.63

Note that P(A U B) represents the probability of either event A or event B occurring, or both.

If events A and B are mutually exclusive, it means they cannot occur at the same time. In other words, if event A occurs, event B cannot occur, and vice versa. In this case, the probability of both events occurring would be zero.

On the other hand, if events A and B are collectively exhaustive, it means that together they account for all possible outcomes. In other words, either event A or event B (or both) must occur, and there are no other possibilities.

Using these definitions, we can see that events A and B are neither mutually exclusive nor collectively exhaustive. This is because the probability of both events occurring (i.e., the intersection of A and B) is not zero, which means they are not mutually exclusive. Additionally, the probability of either A or B occurring (i.e., the union of A and B) is not equal to one, which means they are not collectively exhaustive.

Answer:

x = 5, -5, 3, -3

Step-by-step explanation:

First, substitute u = x^2 into the equation, and we have

u^2 - 34u + 225 = 0

u = x^2

Factor u^2 −34u +225 using the AC method, and we get

( u - 25) ( u - 9) = 0

We know If any individual factor on the left side of the equation is equal to

0, the entire expression will be equal to 0, so

u - 25 = 0

u - 9 = 0

Next, we set u - 25 equal to 0  and solve for u, and we get

u = 25

Then set u - 9 equal to 0 and solve for u, and we get

u = 9

The final solution is all the values that make (u−25)(u−9) = 0  true.

u =25,9

Substitute the real value of u=x^2 back into the solved equation.

x^2 = 25

(x^2)^1 = 9

x^2 = 25

x = 5, -5

Now we solve the second equation

(x^2)^1 = 9

x = 3, -3

So, the answers are: 5, -5, 3, -3
