The polynomial equation kx^2 - 2x^4 = 0 has no real solutions, for any non-zero value of k.

The equation kx^2 - 2x^4 = 0 has the form of a polynomial equation, where k and x are variables. To find the nonzero value of k that will cause the equation to have 2 real solutions, we need to analyze the roots of the equation.

The roots of the equation are the values of x that make the equation equal to zero. To find the roots, we can set each factor of the polynomial equal to zero and solve for x:

kx^2 = 0 and 2x^4 = 0

The first equation gives us x = 0, which is not a valid solution, because it is not a real number.

The second equation gives us x^4 = 0, then x = 0. But x = 0 is not a valid solution for this equation, as it is not a real number.

Therefore, the polynomial equation kx^2 - 2x^4 = 0 has no real solutions, for any non-zero value of k.

The height of the tree is 43.7 feet

Height deals with the length of the tree vertically.  

The given parameters that will help us solve the problem are

The angle of elevation = 63 degrees

The distance from the foot of the tree to the point is 22 feet

Using the trigonometrical ratio

Tan ∅ = Opposite/Adjacent

Tan63 = h/22⁰

Height of the tree = 22*tan63

The height of the tree is equal = 22*1.9626

Reason:

Subtract 5 from both sides

[tex]\sqrt{\text{x}}+5 = 0\\\\\sqrt{\text{x}}=-5\\\\[/tex]

But recall that the range of the parent square root function is the set of nonnegative values. There's no way to have [tex]\text{y} = \sqrt{\text{x}}[/tex] produce a negative number.

Therefore, the equation [tex]\sqrt{\text{x}}=-5[/tex] has no solutions.

----------------------------

Here's what happens if we squared both sides

[tex]\sqrt{\text{x}}=-5\\\\(\sqrt{\text{x}})^2=(-5)^2\\\\\text{x}=25\\\\[/tex]

That's the potential answer, but we need to verify.

[tex]\sqrt{\text{x}}+5 = 0\\\\\sqrt{25}+5 = 0\\\\5+5 = 0\\\\10 = 0\\\\[/tex]

We get a contradiction, which rules out x = 25 being a possible solution.

If you are a visual learner, then check out the graph below.

The curve [tex]\text{y} = \sqrt{\text{x}}+5[/tex] never touches the x axis; this means there's no way for it to have a root and it verifies why [tex]\sqrt{\text{x}}+5 = 0[/tex] has no solutions.

The list that gives the sample space for pulling 2 marbles from the bag with replacement is given as follows:

List 4.

A sample space is a set that contains all possible outcomes in the context of an experiment.

The fact that the experiment is with replacement means that for each of the two marbles, there are two possible outcomes.

Then, applying the Fundamental Counting Theorem, the total number of outcomes is given as follows:

4 x 4 = 16.

This means that the correct list is either the list 3 or the list 4.

As there is replacement, it is possible to take two purple marbles, even though there is only one purple marble, as the same can be taken with replacement, and thus the correct list is given by list 4.

The algebraic expression known as a trinomial contains three terms then the trinomials exists a^2 + b^2 + c^2

What is meant by trinomial?

Three non-zero terms make up a trinomial, which is an algebraic expression. The algebraic expression known as a trinomial contains three terms. An mathematical equation called a trinomial has three terms with on-zero coefficients, each separated by a + or - sign. It is a trinomial if three monomials are divided by addition or subtraction.

When a polynomial has three terms, it is referred to as a trinomial. Its general expression is ax² + bx + c, where a and b are coefficients and c is a constant. In order to factor trinomials, you must follow these three easy steps: Calculate the values of b (middle term) and c. (last term).

A. 8x  

Not a trinomial because, it contains only one term.

B. 3y +5y² + y

2. 2(x2 + 6x) = 3

Quadratic equation is a second-order polynomial equation in a single variable x ax2+bx+c=0. with a ≠ 0 . Because it is a second-order polynomial equation the fundamental theorem of algebra guarantees that it has at least one solution

Let's take a look at the first choice:

2(x² + 6x + 9) = 3 + 18

Now, we will multiply 2 with every member of the other multiplier on the left side:

2·x² + 2·6x + 2·9 = 3 + 18

2x² + 12x + 18 = 3 + 18

2x² + 12x - 3 = 18 - 18

2x² + 12x - 3 = 0

Let's take a look at the second choice:

2(x² + 6x) = 3

Now, we will multiply 2 with every member of the other multiplier on the left side:

2·x² + 2·6x = 3

2x² + 12x = 3

2x² + 12x - 3 = 0

The degree measures of angles d, e, and f are 64 degrees, 99 degrees, and 17 degrees, respectively.

What is the measures of the angles in a triangle?

If we add all three angles in any triangle we get 180 degrees. So, the measure of angle A + angle B + angle C = 180 degrees. This is true for any triangle in the world of geometry.

A) The sum of the angles in a triangle is 180 degrees. Using this fact, we can write:

m∠d + m∠e + m∠f = (4x-4) + (6x-3) + x = 11x - 7

Since this is the sum of the angles in the triangle, it must equal 180 degrees. Therefore, we can write:

11x - 7 = 180

Solving for x:

11x = 187

x = 17

Therefore, x = 17.

B) Now that we know x, we can find the measure of each angle by substituting it into the expressions given for each angle:

m∠d = 4x - 4 = 4(17) - 4 = 64 degrees

m∠e = 6x - 3 = 6(17) - 3 = 99 degrees

m∠f = x = 17 degrees

Therefore, the degree measures of angles d, e, and f are 64 degrees, 99 degrees, and 17 degrees, respectively.

Based on the estimates above, they sold 3 left-handed and 17 right-handed gloves.

17 right-handed gloves and 3 left-handed gloves were sold.

We must create a set of equations to address this issue.

The total number of gloves sold was 12, and the total income was 940.

Gloves for the right hand (x) = 45.

gloves for the left hand (y) = 50.

Equations x+y=20...

45x + 50y = 561 is the first equation (ii)

Equation derived from equation I x + y = 12 – y (iii)

Equation (ii) becomes 45x + 50y = 940

by substituting equation (iii):

x = 12 - u 45

(12 - y) + 50y = 940;

540 - 45y + 50y = 940;

540 + 7y = 561;

7y = 21 y = 3

Equation I becomes x + y = 20 for y = 3, x + 3 = 20x, and 20- x = 17.

The graph of the system of equations y = -2x + 3 and 2x + 4y = 8 is a pair of straight lines passing through the points (2/3, 5/3).

y = -2x + 3 …. (1)

2x + 4y = 8 …. (2)

Substitute eqn (1) in (2)

2x + 4 (-2x + 3) - 8 = 0

Using the multiplicative distributive property, we get

2x - 8x + 12 = 8

By rearranging the above eqn, we get

2x - 8x = 8 - 12

-6x = - 4

Dividing both sides by -2, we get

3x = 2

x = 2/3

Put the value of x in eqn (1)
