The polynomial is  4x^3 - 18x^2 + 2x + 12

A polynomial of degree 3 that satisfies, we need to use the fact that if a polynomial has a zero at x = a, then (x - a) is a factor of the polynomial. So, for the given zeroes, we have the factors (x + 1/2), (x - 2), and (x - 3).

Multiplying these factors together, we get:

(x + 1/2)(x - 2)(x - 3) = (x^2 - (3/2)x - 1)(x - 3) = x^3 - (9/2)x^2 + (1/2)x + 3

To get a constant coefficient of 12, we need to multiply this polynomial by a constant. Since the current constant coefficient is 3, we need to multiply by 4:

4(x^3 - (9/2)x^2 + (1/2)x + 3) = 4x^3 - 18x^2 + 2x + 12

So, the polynomial that satisfies the given conditions is:

P(x) = 4x^3 - 18x^2 + 2x + 12

The polynomial is  4x^3 - 18x^2 + 2x + 12

Based, on the given information, the length of the ramp z, is equal to 53 inches.

A triangle is said to be right-angled if one of its internal angles is 90 degrees, or if any one of its angles is a right angle. The right triangle or 90-degree triangle is another name for this triangle. In geometry, the right triangle is significant.

A triangle is said to be right-angled if one of its edges is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the parts that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.

In a right-angled triangle, the square of the hypotenuse side is equivalent to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three edges are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposing the 90° angle, the hypotenuse in this case is the longest side. When the positive number sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.

In this question, the base, the height and the length of the ramp form a right angled triangle.

To find the length, we will use Pythagoras theorem, which states that,

(hypotenuse)² = (base)²+ (height)²

Substituting the values, we get

x²=45²+ 28²

x²= 2809

x=√2809

A = |λ-6 0 0| . |0 λ 4| . |0 5 λ-1| λ 1= 4.79 λ 2= 4.79 λ3 = 4.79, as the highest value of lif it exists is 4.79. therefore X=4.79

To find the values of λ for which det(A) = 0, we need to solve the equation det(A) = 0. The matrix determinant of a 3x3 matrix A is given by:

[tex]det(A) = a11(a22a33 - a23a32) - a12(a21a33 - a23a31) + a13(a21a32 - a22a31)[/tex]

In this case, the matrix A is:
A = |λ-6 0 0|
   |0 λ 4|
   |0 5 λ-1|

So, the determinant of A is:
[tex]det(A) = (λ-6)(λ(λ-1) - 4*5) - 0(0(λ-1) - 4*0) + 0(0*5 - λ*0)[/tex]
Simplifying the equation, we get:
[tex]det(A) = (λ-6)(λ^2 - λ - 20)[/tex]

Step-by-step explanation:

The equation 4(x - 2) = 2(2x + 6) has no solution.

To solve the equation 4(x - 2) = 2(2x + 6), we must first use the distributive property to expand the equations. The distributive property states that a(b + c) = ab + ac.

Using the distributive property, we can expand the equation as follows:

4(x - 2) = 2(2x + 6)

4x - 8 = 4x + 12

Next, we must isolate the variable on one side of the equation. We can do this by subtracting 4x from both sides of the equation:

-8 = 12

This equation is not true, so there is no solution to the equation 4(x - 2) = 2(2x + 6).

In conclusion, the equation 4(x - 2) = 2(2x + 6) has no solution.

The polynomial that 3x^(2)-22x+26 is divided by is x - 6.

To find the polynomial that 3x^(2)-22x+26 is divided by, we can use the formula:

Dividend = Quotient * Divisor + Remainder

In this case, the dividend is 3x^(2)-22x+26, the quotient is 3x-4, and the remainder is 2. We can plug these values into the formula and solve for the divisor:

3x^(2)-22x+26 = (3x-4) * Divisor + 2

Next, we can rearrange the equation to isolate the divisor:

Divisor = (3x^(2)-22x+26 - 2) / (3x-4)

Divisor = (3x^(2)-22x+24) / (3x-4)

Now, we can use polynomial long division to find the divisor:

```
3x - 4 | 3x^2 - 22x + 24

Answer:

Step-by-step explanation:

Here is the answer

The correlation coefficient measures the strength of the linear relationship between two variables, and it ranges from -1 to 1. A correlation coefficient of -1 indicates a perfect negative linear relationship between the variables, which means that as one variable increases, the other decreases at a constant rate.

To find the value of A in this scenario, we need to look for a perfect negative linear relationship between the two variables, time (x) and distance from destination (y). The table shows that as time increases, the distance from the destination decreases, but we need to find the exact rate of change.

We can calculate the rate of change by finding the slope of the line that represents the relationship between time and distance. We can use the formula for the slope of a line, which is:

slope = (change in y) / (change in x)

If we choose the first and last points in the table, we get:

slope = (690 - 1060) / (7 - 1) = -70

This means that for every hour of time that passes, the distance from the destination decreases by 70 miles. Therefore, if the correlation coefficient is -1, we should see a perfect negative linear relationship between time and distance, with a slope of -70.

To check if A is the correct value, we can use the formula for the equation of a line in slope-intercept form:

y = mx + b

where m is the slope and b is the y-intercept. We can plug in the values of m and b and solve for A:

y = -70x + b

If we use the first point in the table, where x = 4 and y = 1000, we get:

1000 = -70(4) + b

b = 1220

So the equation of the line is:

y = -70x + 1220

If we plug in the values of x for the remaining points in the table, we get:

y = 1030 when x = 0

y = 880 when x = 2

y = 800 when x = 3

y = A when x = 5

y = 760 when x = 6

To find the value of A, we can plug in the corresponding value of y and solve for A:

1030 = -70(0) + 1220

880 = -70(2) + 1220

800 = -70(3) + 1220

760 = -70(6) + 1220

A = -70(5) + 1220 = 850

Therefore, the value of A should be 850 if the correlation coefficient for the data shown in the table is -1.

                                    [tex]5x^2 - 2x[/tex]

The divisor is [tex]x^3 - x^2 + 2[/tex] and the dividend is [tex]3x^4 - x^2[/tex]. We start by dividing the highest degree term of the dividend by the highest degree term of the divisor, which gives 3x. We then multiply the divisor by this quotient and subtract the result from the dividend. We repeat this process with the resulting polynomial until the degree of the remainder is less than the degree of the divisor.

In this case, the remainder is [tex]5x^2-2x[/tex], which has a degree of 2 (less than the degree of the divisor). Therefore, we have found the quotient and remainder of the division.
