because A) the prices will always be positive numbers B) the wings make it possible to fly C) you can hace any possible answer in these questions D) anything is possible

The factors of the form (x - c) are (x - 2) and (x² + 49).

To factor the polynomial f(x) = x³ - 2x² + 49x - 98 into factors of the form (x - c), we can use synthetic division with the given zero of 2.

2 | 1 -2 49 -98
  |     2  0  98
    1  0 49   0

The result of the synthetic division gives us the quotient (x² + 49) and a remainder of 0, confirming that 2 is indeed a zero of the polynomial.

Now we can write the polynomial as the product of (x - 2) and the quotient (x² + 49):

f(x) = (x - 2)(x² + 49)

Since the quadratic factor (x² + 49) cannot be factored further using real numbers, the final factorization of the polynomial is:

f(x) = (x - 2)(x² + 49)

The magnitude of the vector ū is approximately 5.10, and the angle is approximately 281.31°.

The magnitude of a vector is the length of the vector, and is calculated using the Pythagorean Theorem. The angle of a vector is the direction in which the vector points, measured counterclockwise from the positive x-axis.

To find the magnitude of the vector ū = (-1,5), we can use the formula:

magnitude = √(x^2 + y^2)

where x and y are the components of the vector.

Plugging in the values of x and y from the vector ū, we get:

magnitude = √((-1)^2 + (5)^2)

Simplifying the expression, we get:

magnitude = √(1 + 25)

magnitude = √(26)

magnitude ≈ 5.10

To find the angle of the vector, we can use the formula:

angle = tan^-1(y/x)

Plugging in the values of x and y from the vector ū, we get:

angle = tan^-1(5/-1)

angle = tan^-1(-5)

angle ≈ -78.69°

Since the angle is measured counterclockwise from the positive x-axis, we need to add 360° to get the angle in the correct quadrant:

angle = -78.69° + 360°

angle = 281.31°

Therefore, the magnitude of the vector ū is approximately 5.10, and the angle is approximately 281.31°.

The value of x in the triangle given the midsegment points and sections is 1.35 units

The mid-segment of a triangle (also called a midline) is a segment joining the midpoints of two sides of a triangle.

The midsegments of triangle UWY are VR, VZ, ZR

To find the value of x, we use a theorem called the mid segment theorem which states that:

"The mid-segment of a triangle, which joins the midpoints of two sides of a triangle, is parallel to the third side of the triangle and half the length of that third side of the triangle."

The third side of triangle UWY is WY and it measures 2.7.

Therefore, x will be 2.7 divided by 2 2.7/2 which will give us the value 1.35 i.e. x = 1.35

The answer is f(-x) = x^4 + 6x + 2 and the function is neither even nor odd.

To find f(-x), we simply substitute -x for x in the original function:

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

Now, to determine if f is even, odd, or neither, we compare f(x) and f(-x). If f(x) = f(-x), then the function is even. If f(x) = -f(-x), then the function is odd. If neither of these conditions are met, then the function is neither even nor odd.

In this case, f(x) = x^4 - 6x + 2 and f(-x) = x^4 + 6x + 2. These are not equal, so the function is not even. However, if we multiply f(-x) by -1, we get:

-f(-x) = -x^4 - 6x - 2

This is also not equal to f(x), so the function is not odd either. Therefore, the function is neither even nor odd.

Alice will receive £80 and Brian will receive £320

When dividing an amount of money in a given ratio, we need to first determine the total number of parts that the ratio is divided into.

In this case, the ratio between Alice and Brian is 1:4. This means that for every 1 unit of money that Alice receives, Brian receives 4 units of money. Therefore, the total number of parts in this ratio is 1 + 4 = 5.

To divide £400 in the ratio of 1:4, we need to find out how much of the total amount each part represents. To do this, we divide the total amount by the total number of parts:

£400 ÷ 5 = £80

So each part in this ratio represents £80.

Now that we know the value of each part, we can calculate how much Alice and Brian will receive.

Alice's share is one part, which represents £80. Therefore, Alice will receive

1 part x £80 = £80

Brian's share is four parts, which represents 4 x £80 = £320. Therefore, Brian will receive:

Answer:

The given function is f(x) = √(x-2) - 2.

The graph that represents this function will have the following characteristics:

The domain of the function is x ≥ 2, since the expression inside the square root must be non-negative.

The function approaches the x-axis but never touches it as x approaches positive infinity, since the square root will always be positive.

The function has a vertical asymptote at x = 2, since the expression inside the square root becomes zero at x = 2.

The function has a horizontal asymptote at y = -2, since the square root term dominates the function as x gets large, and the -2 term remains constant.

Based on these characteristics, you can compare the given graphs to see which one matches the given function.

We can conclude that the Ratio of arc = scale factor of dilation.

An arc in mathematics is a section of a circle's or curve's perimeter. An open curve is another name for it.

The circumference of a circle, sometimes referred to as its perimeter, serves as its boundary. The distance between any two locations traced along the circle of an arc is hence its length.

Given : Radius of original circle A = 3

            Radius of Dilation circle B = 9

We know that, Scale factor of dilation =

Dimension of Dilation shape / Dimension of original shape

So, Scale factor of given dilation = Radius of Circle B / Radius of Circle A

                                                      = 9/3

                                                      = 3.

Now, we know that arc of a circle can be found by using formula:

= Ф × π/180° × r

Arc of Circle A=  90 × π/180 × 3

                       = 3π/2

Arc of Circle B = 90 × π/180 × 9

                        = 9π/2

So, Ratio of arc = Arc of Circle B/Arc of Circle A

                         = 9π/2 ÷ 3π/2 = 3.

Hence, we can see that Ratio of arc = scale factor of dilation.

Answer: Point B is (-2,0) and Point C is (0,3)

Step-by-step explanation:

We know x-intercept is when y=0 and y-intercept is when x=0

Let's first find the x-intercept by replacing y with 0.

6x-4(0)=-12

now let's solve for x

6x-0=-12

x=-2

so Point B is (-2,0)

Now let's find the y-intercept by replacing x with 0

6(0)-4y=-12

now solve for y

-4y=-12

y=3

So point C is (0,3)

The overall chances of winning the games before playing were 52%, and after playing and winning once but losing twice, the overall chances of winning are 17.33%. This shows that the new information has changed your belief about the probability of winning, and you now suspect that your chances of winning are lower than before.

Before playing the games, the expected value of winning is calculated by multiplying the probability of winning with the corresponding probabilities and adding them together. This is shown below:

E(win) = (0)(0) + (0.1)(0.01) + (0.2)(0.02) + (0.3)(0.04) + (0.4)(0.1) + (0.5)(0.15) + (0.6)(0.2) + (0.7)(0.25) + (0.8)(0.16) + (0.9)(0.04) + (1)(0) = 0.52

After playing the games and winning once but losing twice, the expected value of winning is calculated by multiplying the probability of winning with the corresponding probabilities, and adding them together. However, the probabilities are adjusted based on the new information. The new probabilities are shown below:

P(win) = (0)(0) + (0.1)(0.01)(1/3) + (0.2)(0.02)(1/3) + (0.3)(0.04)(1/3) + (0.4)(0.1)(1/3) + (0.5)(0.15)(1/3) + (0.6)(0.2)(1/3) + (0.7)(0.25)(1/3) + (0.8)(0.16)(1/3) + (0.9)(0.04)(1/3) + (1)(0)(1/3) = 0.17333

Therefore, the overall chances of winning the games before playing were 52%, and after playing and winning once but losing twice, the overall chances of winning are 17.33%. This shows that the new information has changed your belief about the probability of winning, and you now suspect that your chances of winning are lower than before.

Step-by-step explanation:

Part A: In this situation, a Type II error would take place if the council failed to reject the null hypothesis even if it was untrue (i.e., less than 40% of children under the age of 5 could pass a swim test).

If the researcher does not reject a null hypothesis that is actually wrong in the population, this is known as a type II error (false-negative). Notwithstanding the fact that type I and type II mistakes cannot be completely prevented, the researcher can lessen their risk by increasing the sample size.

from the question:

Part A: In this situation, a Type II error would take place if the council failed to reject the null hypothesis even if it was untrue (i.e., less than 40% of children under the age of 5 could pass a swim test). This would result in a lost chance to provide these kids with more swim safety training, perhaps placing them in danger of drowning or other swimming-related mishaps.

Part B: We are unable to reject the null hypothesis since the p-value (0.8438) exceeds the significance level (0.05). This indicates that there is insufficient information to draw the conclusion that less than 40% of children under the age of five can pass a swim test. But, since the test only looked at the alternative hypothesis that the fraction is less than 40%, we cannot draw the conclusion that it is exactly 40%.

Part C: One possible defect in the study is the use of a volunteer sample. The children who volunteered to take the swimming test may not be representative of the entire population of children under 5 in Bloomburg City. For example, parents who are more concerned about their children's swimming abilities may be more likely to volunteer their children for the test, leading to a biased sample. To obtain a more representative sample, a random sample of children under 5 could be selected from the population and asked to take the swimming test.

We can use the calculation for the distance between the two provided vertices to determine the length of one side:

sqrt[(7 - (-3))2 Plus (6 - 5)2] yields AB. = sqrt[10^2 + 1^2] = sqrt(101) (101)

Since the five sides of a normal pentagon are all the same length, one side's length is:

sqrt(101) / 5
