The sum of the roots of 2x² − 6x + 1 = 0 is 3 and the product is 0.5076.

The values of variables that satisfy the given quadratic equation are known as its roots. In other words, x = α is a root of the quadratic equation f(x) if f(α ) = 0. The real roots of an equation f(x) = 0 are the x-coordinates of the points where the curve y = f(x) intersects the x-axis.

To find  sum and the product we first need to find roots/zeroes of the quadratic equation 2x² − 6x + 1 = 0, i.e.

⇒ 2x² − 6x + 1

⇒ 2x²−6x + 1

Putting them in quadratic equation

[tex]$ \Rightarrow x={\frac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}[/tex]

[tex]$ \Rightarrow x={\frac {-(-6)\pm {\sqrt {(-6)^{2}-4(2)(1)}}}{2(2)}}[/tex]

[tex]$ \Rightarrow x = \frac{3 -\sqrt{7} }{2}[/tex], [tex]$ \Rightarrow x_2 = \frac{3 +\sqrt{7} }{2}[/tex]

⇒ x = 0.177124,  x₂ = 2.822876

⇒ x = 0.18,  x₂ = 2.82

The sum of the equation roots of 2x² − 6x + 1 = 0 is

0.18 + 2.82 = 3

The Product of the equation roots of 2x² − 6x + 1 = 0 is

0.18 × 2.82 = 0.5076

Thus, The sum of the roots of 2x² − 6x + 1 = 0 is 3 and the product is 0.5076.

Answer:

  p:q:r = 12:15:10

Step-by-step explanation:

Given p:q = (2/3):(5/6) and q:r = (3/4):(1/2), you want p:q:r.

We can turn each ratio into a ratio of integers by multiplying by the least common denominator.

  p:q = 4:5 . . . . . . . multiply the given ratio by 6

  q:r = 3:2 . . . . . . . multiply the given ratio by 4

Now, we need to have q be represented in each ratio by the same number. That number will be the least common multiple of its representations in these ratios: LCM(5, 3) = 15.

Multiplying the first ratio by 3, we have ...

  p : q = 12 : 15

Multiplying the second ratio by 5 gives ...

  q : r = 15 : 10

Now, we can write the ratio of interest:

  p : q : r = 12 : 15 : 10

Answer:20

Step-by-step explanation: 5+5+5+5

Answer:

4 times 5 is equal to 20.

Step-by-step explanation:

Using the law of cosines we know that the outfielder throws the ball 169.26 feet away.

The law of cosines in trigonometry establishes a relationship between a triangle's side lengths and the cosine of one of its angles.

According to the Law of Cosines, c2=a2+b22ab cosC.

With the exception of the third component, which equals zero if C is a straight angle and the Pythagorean Theorem results, this is similar to the Pythagorean Theorem.

So, here, the pitcher's mound is 60.5 feet away from home plate.

Additionally, the ball traveled 216 feet when it was struck by the bat.

Allow the outfielder to toss the ball x feet away.

According to the diagram below:

x² = 216² + 60.5² - 2 * 216 * 60.5 * cos34°

x = 169.258748677 ⇒ 169.26 feet

Therefore, using the law of cosines we know that the outfielder throws the ball 169.26 feet away.

Correct question:

Use the law of cosines to solve the problem. On a baseball field, the pitcher's mound is 60.5 feet from home plate. During practice, a batter hits a ball 216 feet. The path of the ball makes a 34° angle with the line connecting the pitcher and the catcher, to the right of the pitcher's mound. an outfielder catches the ball and throws it to the pitcher. how far does the outfielder throw the ball?

he system of equations used to represent this scenario is y = –x + 10 and y = 4x, where x and y are the two numbers.

To find the larger number, we can solve the system of equations by setting y = 4x in the first equation and solving for x.

y = –x + 10

4x = –x + 10

3x = 10

x = 10/3

So the smaller number is 10/3. To find the larger number, we know that it is 4 times the smaller number, which is 4(10/3) = 40/3.

Therefore, the larger number is 40/3.

Answer:

The larger number = 8

Step-by-step explanation:

Below is the system of equations:

y = -x + 10

y = 4x

Since both equations equal "y", we can set them equal to each other:

4x = -x + 10

4x + x = 10

5x = 10

x = 2              

This means that at x = 2, the y-values of both equations are the same and is when the criteria of "the sum of two numbers are 10 and the larger number is 4 times the smaller number" is met

"x" is the smaller number. To find the bigger number, input "x" into either one of the equations in the system:

y = 4(2) = 8

Since ​14​ is equivalent to 8x, that number must be 14 ÷ 8. Then ​14 ÷ 8 = x, because of the inverse relationship between multiplication and division.

There are 4 basic mathematical operations which are addition, subtraction, division and multiplication.

Multiplication and division are inverse operations because multiplication undoes division and also division undoes multiplication.

We want to find the quotient of 14 and 8. This is expressed as 14 ÷ 8.

Now, we are told to consider that some number times 8 equals ​14. Let the number be x and as such we have;

The midline theorem claims that cutting along the midline of a triangle creates a segment that is parallel to the base and half as long.

The condition for the midline theorem is that the two triangles must have the same size and shape, so all three sides have the same length, and all three angles have the same measure.

For the theorem, we draw a line through two points on either side of the triangle and then we prove that the line divides the sides into equal halves. Once proven that the sides are in two equal halves using congruency it is proved that the base and midline are parallel.

Since the base and midline are parallel to each other using the SAS rule of congruency therefore according to the theorem the segment is half as long as the base.

Answer:

  a.  x²

  b.  144 cm²

Step-by-step explanation:

You want to know an expression for the area of the four white triangles in the given figure, and you want to know that area when x = 12 cm.

If you draw horizontal and vertical lines through the middle of the figure, you can see that for each white triangle there is a matching shaded triangle. That is, the shaded area is equal to the white area.

The shaded area is the square of the length of the side of the shaded square, so is ...

  shaded area = x²

The white area is the same, so is ...

  white area = x²

Using x = 12 cm, the formula from part (a) tells us ...

  white area = (12 cm)² = 144 cm²

The total area of the four white triangles is 144 cm².

__

Additional comment

The relation between the side lengths of the shaded area and the side length of the total area is ...

  2x/√2 = x+6

This has one solution: x = 6/(√2 -1) ≈ 14.485281 (cm).

The figure cannot be drawn to scale for any other value of x, so it is impossible for x=12 cm, unless the outside length is (x+4.97056...)

If you take the white triangles to be isosceles right triangles, each will have an area of A = 1/2bh = 1/2(x/√2)(x/√2) = x²/4. The four of them will have an area of 4(x²/4) = x². If you take the white area to be the overall area less the area of a square of side length x, then the area of the four triangles will be (x+6)² -x² = 12x+36. You will notice that these expressions give different values of the area of the white triangles when x=12. (See the previous comment about the value of x.)

By finding the unit rates for the two jars, we will see that the better option is the 28-ounce jar.

To find wich option is the better buy, we need to find the unit rate for each of these jars.

To get the unit rate, we need to take the quotient between the cost of each jar and the volume of peanut butter that each jar has.

We know that the jar of 28 ounces has a cost of $4.29, then its unit rate is:

U =  ($4.29)/28 oz = $0.153 per oz.

This means that with this jar, each ounce costs $0.153

For the 16 ounce jar, the cost is $2.49, then the unit rate is:

So here the cost per ounce is larger, then the better option is the 28-ounce jar.

The distance between Afia's school and her babysitter's house is 16 units.

Distance is a measurement of how far away two things or locations are, either numerically or occasionally qualitatively. Distance can refer to a physical length in physics or to an estimate based on other factors in ordinary language.

The distance between two points in a coordinate plane can be found using the distance formula:

d = √((x2 - x1)^2 + (y2 - y1)^2)

Where (x1, y1) and (x2, y2) are the coordinates of the two points, and d is the distance between them.

In this case, the coordinates of Afia's school are (-8, -3) and the coordinates of her babysitter's house are (8, -3).

Plugging these values into the distance formula:

d = √((8 - (-8))^2 + (-3 - (-3))^2)

d = √((8 + 8)^2 + (0)^2)

d = √(16^2)

d = √(256)

d = 16 units
