The two values of x that are roots of the polynomial are:

x = -5 + i√11/2

x = -5 - i√11/2

Polynomial is an equation written as the sum of terms of the form kx^n.

where k and n are positive integers.

We have,

x² + 5x + 9 = 0

It is in the form of ax² + bx + c

a = 1

b = 5
c = 9

Using the determinant.

x = -b ± √(b² - 4ac) / 2a

x = -5 ± √(25 - 36) / 2

x = -5 ± √-11 / 2

x = -5 ± i√11/2

Where i = √-1

Thus,

The roots of the polynomial are:

x = -5 + i√11/2 and x = -5 - i√11/2

When x = 10 the equations are equal and when x gets any value the two equations are equal.

What is equation ?

An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated by the symbol "equal."

The equals sign is a part of mathematical expressions known as equations. Often, algebra is used in equations. When a calculation requires an exact number but you don't know it, algebra is utilized.

When x = 10 the equation becomes

6x³ + 9x² + 4x + 7

6(10)³ + 9(10)² + 4(10) + 7

= 6000 + 900 + 40 + 7

= 6947

6x³ + 3x² + 6x² + 4x + 5 + 2

= 6x³ + 9x² + 4x + 7

= 6(10)³ + 9(10)² + 4(10) + 7

= 6000 + 900 + 40 + 7

= 6947

Both the equations are equal when x = 10

When x = -3/2 the equation becomes

6x³ + 9x² + 4x + 7

6(-3/2)³ + 9(-3/2)² + 4(-3/2) + 7

= -20.25 + 20.25 + 6 + 7

= 13

6x³ + 3x² + 6x² + 4x + 5 + 2

= 6x³ + 9x² + 4x + 7

= 6(-3/2)³ + 9(-3/2)² + 4(-3/2) + 7

= -20.25 + 20.25 + 6 + 7

The bisector of the angle TUV is attached below.

What is an angle?

In Euclidean geometry, an angle is the shape created by two rays that share a terminus and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.

The steps to draw a bisector of an angle:

1) Cross both rays with an arc. Place the compass point at the vertex of the angle after opening it to any width. Swing the compass so the pencil creates an arc that spans the angle's two rays.

2) Make a vertical arc inside. Place the compass such that the point is at the spot where the first ray and the first arc connect. Swing the compass to create an arc that fits inside the angle.

3) To intersect the first interior arc, draw a second interior arc. Move the point to the spot where the first arc crosses the second ray without altering the compass's breadth. Draw an internal arc by swinging the compass and intersecting it with the initial interior arc you drew.

4) From the vertex to the spot where the arcs meet, draw a line. To make sure the line is exact, use a straightedge. This line cuts the angle in half.

c.) Change in y / Change in x - yes

d.) rise/run - yes

e.) inverse - Not apply

What is the difference between rate of change and slope coefficient?

The terms rate of change, gradient, slope coefficient, and rise over run are all equivalent to the slope in a proportional relationship. The slope of a line describes the rate at which a variable changes in relation to another variable. Rate of change is the same concept, but it is more general and can be applied to any relationship, not just linear. Gradient is another term for the slope of a line, which is the change in one variable compared to the change in another variable. Slope coefficient is a mathematical term for the slope of a line, which is the ratio of the vertical change to the horizontal change. Rise over run is another term for the slope of a line, which describes the rate of change by measuring the vertical change (rise) over the horizontal change (run). All of these terms describe the same concept, which is the rate of change in a proportional relationship.

Answer:

To find the five-number summary for a set of data, we need to find the minimum, first quartile, median, third quartile, and maximum of the data. To find the interquartile range, we subtract the first quartile from the third quartile.

The minimum temperature in the list is 50 degrees Fahrenheit. The maximum temperature is 80 degrees Fahrenheit. To find the median, we need to first find the middle value in the list. Since there are 13 temperatures in the list, the middle value is the seventh temperature, which is 64 degrees Fahrenheit.

To find the first and third quartiles, we need to divide the list into two halves at the median. The first half of the list contains the first six temperatures, and the second half contains the last six temperatures. The median of the first half of the list is the average of the third and fourth temperatures, which is 55 degrees Fahrenheit. The median of the second half of the list is the average of the sixth and seventh temperatures, which is 61.5 degrees Fahrenheit.

Therefore, the five-number summary for this data set is:

Minimum: 50

Lower quartile: 55

Median: 64

Upper quartile: 61.5

Maximum: 80

The interquartile range is the difference between the upper and lower quartiles, which is 61.5 - 55 = 6.5.

The distances travelled in each hour for both part are given as 5760 m and 5.76 km respectively.

A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.

Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.

The given problem can be solved by ratio method as follows,

(A)  The average walking rate is 1.6 m/s

The speed in meter per hour is calculated as,

1 second = 1/3600 hour

Take the ratio of 1.6 and 1/3600 as follows,

1.6 ÷ 1/3600

= 3600 × 1.6

= 5760

(B) The average walking rate is 1.6 m/s

It implies that 1.6 m in 1 second.

Now, 1 m = 1/1000 km

=> 1.6 m = 1.6/1000 km

And, 1 second = 1/3600 hour

Thus, the distance travelled in kilometer per hour can be evaluated by taking the ratio as follows,

1.6/1000 ÷  1/3600

= (3600 × 1.6)/1000

= 5.76

Hence, the distances travelled per hour in meter and kilometer are given as 5760 m and 5.76 km respectively.

Answer:

Step-by-step explanation:

You want two transformations that will map segment AB to segment A"B", where the points are A(1, 1), B(5, 3), A"(-5, -2), B"(-9, 0).

We notice that the difference B-A is (5 -1, 3 -1) = (4, 2), and the difference B"-A" is (-9 -(-5), 0 -(-2)) = (-4, 2). These values have the same magnitudes, so we know no dilation is involved. The sign of the x direction of the segment has been reversed, which means the segment has been reflected horizontally. (B" is left of A", where B is right of A.)

Reflection over any vertical line will do, but the simplest is reflection over the y-axis.

The first transformation can be reflection over the y-axis.

The reflected line segment will be ...

  (x, y) ⇒ (-x, y)

  A(1, 1) ⇒ A'(-1, 1)

  B(5, 3) ⇒ B'(-5, 3)

The value that must be added to A' to move it to A" is ...

  A" -A' = (-5, -2) -(-1, 1) = (-5 -(-1), -2-1) = (-4, -3) . . . . . . left 4, down 3

Similarly, the value that must be added to B' to move it to B" is ...

  B" -B' = (-9, 0) -(-5, 3) = (-9 -(-5), 0 -3) = (-4, -3) . . . . . . left 4, down 3

That is, the entire segment A'B' can be moved to A"B" by a translation left 4 and down 3.

The second transformation can be translation left 4 and down 3.

__

Additional comment

The translation left could be accomplished by reflection over the line x = -2 instead of the y-axis.

The movement of the line segment could be accomplished in one transformation by rotation 126.87° clockwise about the point (-1.25, -2). The exact angle is arctan(-4/3) in the second quadrant.
