To find the possible integer lengths for diagonal AC in quadrilateral ABCD, the Triangle Inequality Theorem is used. Possible integer values for AC are constrained between the sum and the difference of the lengths of the sides forming triangles ABC and CDA, resulting in potential lengths of 4, 5, 6, and 7.

The question pertains to finding all possible integer values for the diagonal AC of a quadrilateral ABCD given the lengths of the sides. To determine the possible lengths of AC, we need to inspect the properties of triangles that could form within the quadrilateral upon drawing this diagonal. The quadrilateral could possibly be a rectangle, a square, or a parallelogram, but without further information, we assume it is an irregular quadrilateral.

By using the Triangle Inequality Theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side, we can determine possible values for AC. Since ABCD is a quadrilateral with sides AB = 3, BC = 6, CD = 4, and DA = 4, diagonal AC can create two triangles, ABC and CDA. For triangle ABC, the sum of sides AB and BC is 9, so AC must be less than 9. Similarly, for triangle CDA, the sum of sides CD and DA is 8, so AC must be less than 8. Therefore, the maximum value for AC is 7. However, AC must also be greater than the difference of the sides, 3 for triangle ABC and 0 for triangle CDA. This leaves us with possible integer values of 4, 5, 6, and 7 for AC.

Answer:

A. 12 square units.

Step-by-step explanation:

We have been given graph of a triangle and we are asked to find the area of our given triangle.

Since we know that area of a triangle is half the product of height of triangle and base of the triangle.

[tex]\text{Area of triangle}=\frac{1}{2}*\text{Base*Height}[/tex]

We can see that MN is base of our triangle and LM is height of triangle, so let us find lengths of MN and LM using distance formula.

[tex]\text{Distance}=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

[tex]\text{Distance between point M and N}=\sqrt{(3--1)^2+(-4--4)^2}[/tex]

[tex]\text{Distance between point M and N}=\sqrt{(3+1)^2+(-4+4)^2}[/tex]

[tex]\text{Distance between point M and N}=\sqrt{(4)^2+(0)^2}[/tex]

[tex]\text{Distance between point M and N}=4[/tex]

[tex]\text{Distance between point L and M}=\sqrt{(-1--1)^2+(-4-2)^2}[/tex]  

[tex]\text{Distance between point L and M}=\sqrt{(-1+1)^2+(-6)^2}[/tex]  

[tex]\text{Distance between point L and M}=\sqrt{0+36}[/tex]  

[tex]\text{Distance between point L and M}=6[/tex]  

Now let us substitute our side lengths is area formula.

[tex]\text{Area of triangle LMN}=\frac{1}{2}*4*6[/tex]

[tex]\text{Area of triangle LMN}=2*6[/tex]

[tex]\text{Area of triangle LMN}=12[/tex]

Therefore, area of triangle LMN is 12 square units and option A is the correct choice.

Answer:

I think the answer is 77.

Step-by-step explanation:

The range of the function (eˣ)/(eˣ+c) is the closed interval [0,1].

The range of the function f(x) = (eˣ)/(eˣ+c) can be determined by analyzing the behavior of the function as x approaches positive and negative infinity. When x tends to positive infinity, the term eˣ grows much faster than c, so the denominator approaches infinity. Therefore, the function approaches 1 as x tends to infinity.

Similarly, when x tends to negative infinity, the term eˣ approaches 0 much faster than c, so the denominator becomes negligible. As a result, the function approaches 0 when x tends to negative infinity.

Since the function approaches 0 at negative infinity and approaches 1 at positive infinity, the range of the function is the closed interval [0,1].

Final answer:

The amount of salt in the tank, described by the differential equation, reaches 5 pounds after 50 minutes with an initial amount of 10 pounds and a rate of change defined by the given equation.

Explanation:

Let's start with the given differential equation: A'(t) = (2 gal/1 min) * (0 lb/1 gal) - (1 gal/1 min) * A(t) / (50 + (2 - 1)t gal).

By simplifying the equation, we get A'(t) + A(t) / (50 + t) = 0. Multiplying through by (50 + t) gives (50 + t)A'(t) + A(t) = 0. Recognizing that ((50 + t)A(t))' equals zero, we integrate to find (50 + t)A(t) = C, where C is a constant.

With the initial condition A(0) = 10, we find 10 = C / (50 + 0), which simplifies to C = 500. So, the equation describing the amount of salt in the tank is A(t) = 500 / (50 + t).

To determine when the tank will be filled, we solve 50 + t = 100, which gives t = 50 minutes. Plugging this into A(t) yields A(50) = 500 / (50 + 50) = 5 lb.

This linear programming problem can be solved by graphing the given inequalities to determine the feasible region. If this region is empty, there are no solutions. If the function is unbounded in this region, the maximal value can be infinitely large.

To solve this linear programming problem, we first need to identify its feasible region which is defined by its constraints. The constraints of this problem are as follows:

By graphing these inequalities we can identify the feasible region as the intersection of these inequalities. If the feasible region is empty, it means that there is no solution that satisfies all the constraints. If the objective function p = x - 2y is unbounded, it means that the maximum value of p can be infinitely large within this feasible region. By investigating both these situations, we should be able to determine whether an optimal solution exists or not.

The task involves evaluating the line integral of a vector field along a path to determine the work done by the field. Since the path does not traverse in the x-direction, only the y and z components of the vector field contribute to the integral. The calculation involves parameterizing each segment and summing up the individual integrals.

The student's question involves finding f · dr along a path c in a vector field. The vector field is given as f = ay i + bz j + cx k, and the path c is a triangle with vertices at (7, 0, 0), (7, 0, 2), and (7, 6, 2). The dot product of a vector field with a differential displacement vector (dr) represents the work done by the field along that path.

To find the integral of f · dr along the path c, we would parameterize each segment of the path and evaluate the line integral. However, since the vector field has constants multiplied by either i, j, or k, and the path only moves parallel to the y and z axes, the components involving x do not contribute to the integral. Therefore, for each segment of the path, we will only consider the y and z components of the vector field. The line integral along the path is then the sum of the integrals over each segment of the triangle.

In this example, since the x-component of the field does not change and the path does not move in the x direction, the integral over the x components will be zero.

Answer:

 286 possible outcomes.

Step-by-step explanation:

We have been given total 13 identical marbles

We need to select 10 out of 13

We will use combination:

[tex]^nC_r=\frac{n!}{r!(n-r)!}[/tex]

here,n=13 and r=10 on substituting the values in the formula we get:

[tex]^13C_{10}=\frac{13!}{10!(13-10)!}[/tex]

[tex]^13C_{10}=\frac{13\cdot 12\cdot 11\cdot10!}{10!\cdot 3!}[/tex]

[tex]\Rightarrow ^13C_{10}=\frac{13\cdot12\cdot11}{3\cdot2\cdot1}[/tex]

[tex]\Rightarrow 286[/tex]

So, there are 286 possible outcomes.

Possible number of outcome that she can select [tex]10[/tex] marbles from [tex]13[/tex] identical marbles are [tex]\boxed{286}[/tex].

Further explanation:

The formula of combination can be expressed as,

[tex]\boxed{^n{C_r} = \frac{{n!}}{{r!\left( {n - r} \right)!}}}[/tex]

Given:

A bag contains [tex]13[/tex] identical marbles.
