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.

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 vertex of the parabola is (5, 4). The solution has been obtained by using quadratic formula.

What is quadratic formula?

The quadratic formula is used to determine an equation's roots. This formula assists in evaluating the solutions of the quadratic equations instead of the factorization approach.

We are given equation as  y = -x² + 10x - 21.

Using quadratic formula, we know that x = -b/2a

So,

x = -10/-2

x = 5

On substituting this in the equation, we get

y = -5² + 10(5) - 21

y = -25 + 50 - 21

y = 4

Hence, the vertex of the parabola is (5, 4).

Answer:

We can use trigonometry to solve this problem.

A is the taller platform, B is the shorter platform, and x is the length of the zipline cable that we want to find.

We can see that the angle between the horizontal and the zipline cable is 12 degrees, so we can use the tangent function to find x:

Therefore, the length of the zipline cable, rounded to the nearest foot, is 209 ft.

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)

To make her prediction more accurate, Kathleen could modify her approach by using a larger and more representative sample size, or by conducting a more in-depth survey that accounts for regional and socioeconomic variations.

Kathleen's prediction is flawed because she assumed that the average number of pets per household would remain the same for all households in the state, which may not necessarily be true. The sample size of 200 households may not be representative of the entire population of households in the state, and there may be variations in the number of pets per household across different regions or socioeconomic groups.

To make her prediction more accurate, Kathleen could modify her approach by using a larger and more representative sample size, or by conducting a more in-depth survey that accounts for regional and socioeconomic variations. Alternatively, she could use data from existing sources, such as census data, to estimate the number of pets per household in different regions of the state and adjust her prediction accordingly. It's also worth noting that factors such as pet ownership trends, cultural attitudes towards pets, and population growth may also impact the accuracy of Kathleen's prediction and should be taken into account.

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°

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.
