The zeros of polynomial 4x² - 1 are x = 1/2 and x = -1/2

Let us assume that given polynomial be p(x) = 4x² - 1

We know that from the definition of zeros , the zeros of a polynomial are nothing but the values of the variable of the polynomial that makes the polynomial value equal to 0.

To find the zeros of polynomial p(x), we need to equate p(x) to zero then solve it for x.

⇒ p(x) = 0

⇒ 4x² - 1 = 0

⇒ 4x² = 1

⇒ x² = 1/4

⇒ x = ±(1/2)

Thus x = 1/2 and x = -1/2 are zeros of given polynomial.

No, a star does not have 5 angles.

A star is a two-dimensional shape that is made up of multiple straight lines. Each straight line must meet at a point, known as a vertex, which forms an angle.

The number of angles in a star depends on the number of points or vertices it has. A five-pointed star, for example, has five angles, each of which is equal to 36 degrees.

However, stars can have any number of vertices, meaning the angles may vary depending on the star.

A star is a two-dimensional shape that has a symmetrical arrangement of points. The points can vary in number, but typically a star has five or more points.

Each point corresponds to a corner of the star, but since a star does not have any sides, it is not possible for it to have five angles. Instead, the corners of the star form vertices, but no angles.

Equiangular triangle

Using the pythagorean theorem: The length of the sides of a 45-45-90 triangle can be easily solved using the pythagorean theorem because it is a right angle triangle.

Recall the formula for the Pythagorean theorem: a 2 + b 2 = c 2; a 2 + b 2 = c2.

To determine the value of (mostly) the hypotenuse in a right triangle, the Pythagorean theorem uses the formula a2+b2=c2. The "non-hypotenuse" sides of the triangle (opposite and adjacent) are a and b.

The well-known geometric theorem known as the Pythagorean theorem states that the square on the hypotenuse (the side opposite the right angle) is equal to the sum of the squares on the legs of a right triangle. This is known as a2 + b2 = c2.

Answer:

x-intercept: (2,0)

y-intercept: (0,-4/3)

vertical asymptote: x = -3

Step-by-step explanation:

To find the x-intercepts, we can set f(x) to 0, which is y=0:

2x-4/x+3 = 0

2x-4 = 0

2x = 4

x = 2

To find the y-intercepts, we can set x to 0:

2(0)-4/(0)+3 = y

y = -4/3

To find the vertical asymptote, we can set the denominator equal to 0:

x+3 = 0

x = -3

The length of the line segment separating two places is the measure of distance between them. Calculating the length of the line segment that connects the two points in the provided coordinates will tell you the distance between them.

The length of the section of a line connecting any two places represents their distance. Only one line connects the two places, and it passes through both.

The length of the line segment that connects the two places may therefore be used to compute the distance between them. The distance between A and B, for instance, is 10 cm if A and B are two points and [Math Processing Error] cm.

Answer:

(- 6, 0 )

Step-by-step explanation:

x - 4y = - 6 → (1)

2x - 12y = - 12 → (2)

multiplying (1) by - 2 and adding to (2) will eliminate x

- 2x + 8y = 12 → (3)

add (2) and (3) term by term to eliminate x

(2x - 2x) + (- 12y + 8y) = - 12 + 12

0 - 4y = 0

- 4y = 0 , then

y = 0

substitute y = 0 into either of the 2 equations and solve for x

substituting into (1)

x - 4(0) = - 6

x - 0 = - 6

x = - 6

solution is (- 6, 0 )

Answer:

x = -6

y = 0

Step-by-step explanation:

For the first equation, x - 4y = -6, we can move -4y to isolate x. Then, the equation will be: x = -6 + 4y. Now, we can use that x to solve for the second equation, 2x - 12y = -12. Let's plug in x from the first equation down to the second one:

2(-6 + 4y) - 12y = -12

Let's solve:

-12 + 8y - 12y = -12

-4y = 0

y = 0

Now that we have y, we can solve for x. Let's plug in y = 0 for the first problem: x-4(0) = -6

x = -6

To complete the project in 36 days, the construction manager would need to add at least 8 more workers to his current team of 12 workers.

If 12 workers can complete a building project in 54 days, to determine this we can divide the rate of work by the number of workers by the number of days: 12 workers / 54 days = 0.2222 workers/day.

If the construction manager wants to complete the project in 36 days, he needs to increase the rate of work to complete the project in that shorter timeframe. To do this, he can add more workers or increase the productivity of the current workers.

To determine how many more workers the manager needs, we can use the formula:

(number of workers) = (rate of work) x (number of days)

By plugging in the desired rate of work and number of days, we get:

(number of workers) = (0.2222 workers/day) x (36 days) = 7.999 workers

To complete the project in 36 days, the construction manager would need to add at least 8 more workers to his current team of 12 workers.

What is algebraic equation ?

An algebraic equation or polynomial equation is an equation of the form P=0 where P is a polynomial with coefficients in some field, often the field of the rational numbers.

Let's call the number of children that swam "x". The number of adults that swam would then be 667 - x.

The total revenue from the children was 1.75x and the total revenue from the adults was 2.25(667 - x).

set up an equation to represent the total revenue from both groups of swimmers

1.75x + 2.25(667 - x) = 1312.25

Expanding the second term on the left-hand side:

1.75x + 1507.75 - 2.25x = 1312.25

Combining like terms:

-0.5x + 1507.75 = 1312.25

Solving for x:

-0.5x = -195.5

x = 391

So, 391 children swam at the public pool that day and 667 - 391 = 276 adults swam.

199 children and 468 adults swam at the public pool that day.

Let x be the number of children and y be the number of adults. Then we have the following two equations:

x + y = 667 (the total number of people)

1.75x + 2.25y = 1312.25 (the total amount of money collected)

We can substitute the first equation into the second to eliminate x:

1.75x + 2.25y = 1312.25

1.75(667 - y) + 2.25y = 1312.25

1175 - 1.75y + 2.25y = 1312.25

1175 = 1312.25 - 1.75y + 2.25y

1175 = 1312.25 - 1.75y + 2.25y

1175 = 1312.25 - 4y/2 + 9y/4

1175 = 1312.25 - (4/2)y + (9/4)y

1175 = 1312.25 - (6/4)y + (9/4)y

1175 = 1312.25 - (15/4)y

1175 + (15/4)y = 1312.25 + (15/4)y

The equation, y = mx + b, is the slope-intercept form of a straight line.

Here, x and y are the coordinates of the points, m is the gradient, and b is the intercept of the y-axis.

y = mx + b is the slope-intercept form of the equation of a straight line. In the equation y = mx + b, m is the slope of the line and b is the intercept.

The value of b is equal to y when x = 0, and m shows how steep the line is. The slope of the line is also called the gradient.

To find the equation of the straight line, we use the slope-intercept form, y = mx + b, where m is the slope of the line, b is the y-intercept of the line.

We can find the equation of a line in the form of y = mx + b, if the coordinates of points forming the line are known to us.

The new current in the circuit is 2.0 amps, which is 1/4th of the original current of 8.0 amps

The relationship between current, resistance, and voltage in an electrical circuit is governed by Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R).

This relationship is represented by the equation I = V/R.

If we know the current and the resistance in a circuit, we can use Ohm's Law to calculate the voltage. For example, if a circuit has a current of 8.0 amps and a resistance of R, then the voltage in the circuit is V = IR = 8.0R.

Now, let's consider the situation where the resistance in the circuit is increased by a factor of 4. If the original resistance was R, then the new resistance is 4*R. Therefore, the new resistance is 4 times greater than the original resistance.

Since Ohm's Law states that current is inversely proportional to resistance, when the resistance is increased by a factor of 4, the current will decrease by a factor of 1/4.

To find the new current, we can use the equation I = V/R, and knowing that V = IR = 8.0R. Then, we can solve for I:

I = V/R = 8.0R / (4R) = 8.0/4 = 2.0 amps

Thus, the new current in the circuit is 2.0 amps, which is 1/4th of the original current of 8.0 amps.
