The answer is:

The option that represents the matrix is the option D:

[tex]3x+6y-z=8\\-2x+3y=4\\4x+5y+4z=-2[/tex]

From the statement we know that the matrix is formed with the information obtained from a system of equations:

Being the values of the first column the values of the variable "x"

Being the values of the second column the values of the variable "y"

Being the values of the third column the values of the variable "z"

Being the values of the fourth column the values of the constant numbers (after the equality)

Knowing that, we are looking for a system equation that contains the following equations:

First equation:

[tex]3x+6y-z=8[/tex]

Second equation:

[tex]-2x+3y=4[/tex]

Third equation:

[tex]4x+5y+4z=-2[/tex]

Hence, we can see that the option that matches with the matrix is the option D.

[tex]3x+6y-z=8\\-2x+3y=4\\4x+5y+4z=-2[/tex]

To identify the vertex and the y-intercept for the function \( y = 0.25(x + 5)^2 \), we will use our knowledge of quadratic functions and their properties.
Vertex:
The given function is in the form of \( y = a(x - h)^2 + k \), where (h, k) is the vertex of the parabola. This form is commonly referred to as the vertex form.
For the given function, \( y = 0.25(x + 5)^2 \), we can see that it is equivalent to \( y = 0.25(x - (-5))^2 + 0 \), indicating that the vertex (h, k) is at (-5, 0). This means the parabola opens upwards (because the coefficient of \( (x + 5)^2 \) is positive) and has its vertex point at x = -5 and y = 0.
Y-intercept:
The y-intercept of a function is found by evaluating the function when x = 0.
So we'll substitute x = 0 into the function to find the y-coordinate of the y-intercept:
\( y = 0.25(0 + 5)^2 \)
Now, we'll calculate the value inside the parentheses:
\( 0 + 5 = 5 \)
Then, we raise it to the power of 2:
\( 5^2 = 25 \)
Finally, we multiply by 0.25:
\( y = 0.25 \times 25 = 6.25 \)
Therefore, the y-intercept where the graph crosses the y-axis is at the point (0, 6.25), where the x-coordinate is 0 and the y-coordinate is the value we just calculated, 6.25.
In summary, the vertex of the function \( y = 0.25(x + 5)^2 \) is (-5, 0), and the y-intercept is at (0, 6.25).

Answer:

side of the pool = 11 m

Step-by-step explanation:

Square Plot:

side = 35 m

Area = 35 * 35 = 1225 sq.m

Area of  lawn = 1104 sq.m

Swimming pool:

Area of the Swimming pool = 1225 - 1104 = 121 sq.m

 side * side = 121 = 11 * 11

side = √11 * 11

side of the pool = 11 m

In physics, we always measure quantities and compare them with a standard. That standard defines a unit of the quantity. Suppose you want to measure the length of a car, so you use a meter stick, which is the standard for measuring distances. Then, why are units of measure important when solving real-world problems? Well, because when solving problems that involve equations, they need to be dimensionally consistent, but what does it mean? it means that you can't add two terms having different units. For instance, you can't add apples with tables!

Answer:

Option D is correct.

Step-by-step explanation:

We need to find the quotient of the polynomials:

[tex](12x^3+14x^2 +9)\div(2x+3)\\[/tex]

The division is shown in the figure attached.

The quotient is: 6x^2-2x+3

The remainder is: 0

So, Option D is correct.

For this case we have that by definition, a quadratic expression is of the form:

[tex]ax ^ 2 + bx + c[/tex]

Where "c" represents the constant term.

Then, given the following expression:

[tex]4h ^ 7- \frac {h} {3} + \frac {1} {2}[/tex]

The constant term is given by:

[tex]\frac {1} {2}[/tex]

Answer:

Option D

Answer:

k = 29

Step-by-step explanation:

(5k -3) + (9+k) = 180

5k-3+9+k = 180

6k + 6 = 180

6k = 180 - 6 = 174

k = 29

The value of k is:

                     k = 29

We know that when two angles lie on a straight line then the sum of the two angles is equal to 180 degree.

Here we have two angles on a straight line as:

first angle = (5k-3)°

and second angle= (9+k)°

Hence, we have:

(5k-3)°+(9+k)°=180°

i.e.

5k-3+9+k=180

on combining the like terms on the left hand side of the equation we have:

5k+k+9-3=180

6k+6=180

6k=180-6

6k=174

i.e.

k=174/6

i.e.

k=29

For this case we must simplify the following expression:

[tex]\frac {\sqrt {10x ^ 3}} {\sqrt {5x}}[/tex]

We combine the expression in a single radical:

[tex]\sqrt {\frac {10x ^ 3} {5x}} =[/tex]

We eliminate common factors of the numerator and denominator:

[tex]\sqrt {\frac {2x ^ 3} {x}} =\\\sqrt {2x ^ 2} =[/tex]

By definition of power properties we have to:

[tex]\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}[/tex]

So:

[tex]\sqrt {2x ^ 2} = x \sqrt {2}[/tex]

Answer:

Option A

Answer:

C.1/16

Step-by-step explanation:

When a coin is tossed 4 times, the number of outcomes are:

2^4 = 16

So,

From the outcomes, only one outcome will be when there will be all heads

So, the probability will be:

One out of the 16 outcomes

Hence, the probability of a coin landing on heads all 4 times is:

C.1/16

The reasonable estimate of the probability is option A.

We know that

Probability = Number of favorable outcomes ÷ Total no of outcomes

So,

Here the number of favorable outcomes should be

= 3 + 2

= 5

And, the total no of outcomes should be

= 2 + 4 + 5 +  3 + 2

= 16

Therefore, option A is correct.

R: 0 ≤ W(b) ≤ 10

D: D: 0 ≤ b ≤ 10

R: 0 ≤ W(b) ≤ 120

W(b) = 12b.

he has enough to build 10 birdhouses, he doesn't have for more than that, he can either build no birdhouses or build 10 birdhouses, since "b" is the independent variable and thus the domain will come from it, what values can "b" safely take?   "b" can be either 0 or more than 0 but nor more than 10, because Owen doesn't have enough for more than that, 0 ≤ b ≤ 10.

let's say owen chooses to build 0 birdhouses, then W(0) = 12(0) => W(0) = 0.

let's say owen chooses to build 10 birdhouses, then W(10) = 12(10) => W(10) = 120.

so the amount of wood needed for those birdhouses, namely the range, can be either 0, if he chooses to build none, or 120 if he chooses to build 10, 0 ≤ W(b) ≤ 120.

Final answer:

The linear equation is solved by distributing the number outside the parentheses, combining like terms, and then isolating the variable x. The final answer is x = 1/4.

Explanation:

To solve the linear equation 3(−4x + 5) = 12, let's follow the standard steps for solving a linear equation.

Distribute the 3 to both terms inside the parentheses: 3 × (−4x) + 3 × 5 = 12, which simplifies to −12x + 15 = 12.

Subtract 15 from both sides of the equation to get the x term by itself: −12x + 15 − 15 = 12 − 15, which simplifies to −12x = −3.

Finally, divide both sides of the equation by −12 to solve for x: −12x / −12 = −3 / −12, which simplifies to x = 1/4.

By following these steps, we've found that the value that satisfies the equation is x = 1/4.

Final answer:

To solve the equation 3(−4x + 5) = 12, distribute the 3, subtract 15 from both sides, and then divide by −12, yielding the solution x = 1/4 or 0.25.

Explanation:

To solve the linear equation 3(−4x + 5) = 12, we'll start by expanding the equation and then isolating x.

Therefore, the solution to the equation 3(−4x + 5) = 12 is x = 0.25.

Final answer:

To find the sum of the first 16 terms of the arithmetic series with a common difference of 6, use the sum formula for an arithmetic series S_n = (n/2) * (2a_1 + (n - 1)*d). By plugging in the values n = 16, a_1 = 1, and d = 6, the sum S_16 is calculated to be 736.

Explanation:

The student has presented an arithmetic series and is asking to find the sum of the first 16 terms (S16). In an arithmetic series, each term increases by a constant difference. The given sequence is 1, 7, 13, 19, and so on, showing a common difference (d) of 6.

Steps to find S16:

Identify the first term (a1) which is 1.

Determine the common difference (d), which is 6 in this case.

Use the formula for the sum of the first n terms of an arithmetic series Sn = (n/2) * (2a1 + (n - 1)*d), where n is the number of terms.

Substitute n = 16, a1 = 1, and d = 6 into the formula and calculate S16.

Now let's calculate S16:

S16 = (16/2) * (2*1 + (16 - 1)*6) = 8 * (2 + 15*6) = 8 * (2 + 90) = 8 * 92 = 736

The sum of the first 16 terms of the given arithmetic series is 736.

The vertex where the two triangles touch forms a pair of vertical angles, so that the angles on opposites sides of the vertex are congruent.

In mathematics, notation like V(x) generally represents a function. Whether it is indeed a function depends on its definition and if every input x corresponds to exactly one output.

In mathematics, V(x) can indeed be a function. The notation V(x) generally represents a function named 'V' that takes an input 'x'. Whether it represents a function in a particular context depends on how it is defined. For a relationship to be a function, every input x must correspond to exactly one output in the function V. For instance, if V(x) is defined as x², then it IS a function, because each input x yields a specific output, which is the square of x.
