Step-by-step explanation:

The equation for the axis of symmetry of the parabola y = - 4 x² + 24 x - 35 is given by x = 3.

We know that the method to find the axis of the symmetry of the parabola is given by:

x = - b / 2 a

We have the general equation of the parabola as:

y = a x² + b x + c

We have the equation of the parabola as:

y = - 4 x² + 24 x - 35

Comparing from this equation, we get that:

a = - 4

b = 24

c = - 35

Now, substituting the values, we get that:

x = - 24 / 2 (- 4)

x = - 24 / - 8

x = 24 / 8

x = 3

Therefore, the equation for the axis of symmetry of the parabola y = - 4 x² + 24 x - 35 is given by x = 3.

Here we have to find zeroes of the given function.

Let's start solving!

\(f(x) = x ^{3} + 9x ^{2} + 6x - 16\)

\(0 = x ^{3} + 9x ^{2} + 6x - 16\)

\(0 - x ^{3} - 9x ^{2} - 6x + 16 = 0\)

\( - x ^{3} + x ^{2} - 10x ^{2} + 10x - 16x + 16 = 0\)

\( - x ^{2} (x - 1) - 10x(x - 1) - 16(x - 1) = 0\)

\( - (x - 1) \times (x ^{2} + 10x + 16) = 0\)

\( - (x - 1) \times (x ^{2} + 8x + 2x + 16) = 0\)

\( - (x - 1) \times (x \times (x + 8) + 2(x + 8)) = 0\)

\( - (x - 1) \times (x + 8) \times (x + 2) = 0\)

\((x - 1)(x + 8)(x + 2) = 0\)

\(x - 1 = 0 \\ x + 8 = 0 \\ x + 2 = 0\)

\(x = 1 \\ x = - 8 \\ x = - 2\)

\( x_{1} = 8, x_{2} = - 2, x_{3} = 1\)

The answer to your question is s. sqrt (316.9) = 17.8 when you take the square root of that number. As a result, the correct response is 17.8.

This is further explained below.

Generally, Because you need to calculate the sample standard deviation to answer the question, use the following formula:

\(s = \sqrt {{ \sum of x - \bar x}{(n - 1} }\)

There are 9 numbers, there, so n - 1 = 8

find the mean

\(\bar x\): 15 + 42 + 53 + . . . + 47 = 227. 227 / 9

x= 25.2

After that, deduct one from each number and then square the output, as seen here:

(15 - 25.2) = 104.0 (42 - 25.2)²

= 282.2 (53 - 25.2)²

= 772.8

After that, total up all of those values. The response to this, using this illustration as an example, is

\(x=\frac{ 2,535.2}{ 8}\)

x= 316.9.

-5/6

Step-by-step explanation:

By the application of Analytical geometry the rate of change of y with respect to x is -5/6.

what is Analytical geometry?

Analytical geometry is a branch of mathematics that studies geometric shapes and figures using analytical methods. It is a branch of mathematics that uses algebraic techniques to describe geometric shapes and figures. It involves the use of analytical equations and formulas to study geometric concepts. Analytical geometry is used to study the properties of points, lines, angles, circles, and other geometric shapes. It can also be used to solve problems involving angles, distances, and areas of figures. In addition, analytical geometry can be used to find the intersection of two lines, calculate the area of a circle, and calculate the volume of a cylinder. Analytical geometry is a powerful tool used in many scientific and engineering fields.

Answer:

Step-by-step explanation:

From the information given:

For Adult Men

Mean \(\mu\) = 69.5

Standard deviation \(\sigma\) = 2.4

observed value X = 74

For Adult Women

Mean \(\mu\) = 63.8

Standard deviation \(\sigma\) = 2.6

observed value X = 70

Therefore ; the values for their z  scores can be obtained in order to determine who is more unusually tall within his or her respective sex

For Adult Men :

\(z = \dfrac{X- \mu}{\sigma}\)

\(z = \dfrac{74- 69.5}{2.4}\)

\(z = \dfrac{4.5}{2.4}\)

z = 1.875

For Adult Women :

\(z = \dfrac{X- \mu}{\sigma}\)

\(z = \dfrac{70- 63.8}{2.6}\)

\(z = \dfrac{6.2}{2.6}\)

z = 2.3846

Thus; we can conclude that , the women is more unusually tall within his or her respective sex

The statement "1 is NOT in the domain" is true because for the function f(x), the expression x - 7 results in division by zero when x equals 1, which makes 1 not a valid input for the function.

To determine if a value is in the domain of a function, we need to consider any restrictions or limitations on the input values.

For the function f(x) = √(x - 7), the square root function is defined only for non-negative values.

Therefore, the expression (x - 7) inside the square root must be greater than or equal to zero. In other words, x - 7 ≥ 0.

Solving this inequality, we find x ≥ 7.

This means that any value of x that is greater than or equal to 7 is in the domain of f(x).

However, the statement is asking specifically about the value 1.

Since 1 is less than 7, it does not satisfy the inequality x ≥ 7 and is therefore not in the domain of f(x).

Similarly, for the function g(x) = 4x - 8, there are no restrictions on the domain.

Any real number can be substituted into the function, including the value 1.

Therefore, the statement "1 isn't in the domain of f(0) g" is not accurate.

It is true that 1 is not in the domain of f(x), but it is in the domain of g(x).

In summary, the correct statement is that "1 is not in the domain."

Answer:

The answer to the question provided is 16 units.

.

Step-by-step explanation:

☆Well, we simply use the distance formula, which is:

\(d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} }\)

...

☆All we need to do is plug in!

\(d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} } \\ \\ d = \sqrt{(9 - 25) {}^{2} + (12 - 12)^{2} } \\ d = \sqrt{( - 16)^{2} + (0) ^{2} } \\ d = \sqrt{256 + 0} \\ d = \sqrt{ 256 } \\ d = 16\)

The distance between point T (-5, 1) and point I (-1, 1) is 4 units.

To find the distance between two points, we can use the distance formula, which is derived from the Pythagorean theorem. The formula is:

Distance = √((x2 - x1)² + (y2 - y1)²)

Let's apply this formula to find the distance between point T (-5, 1) and point I (-1, 1):

x1 = -5, y1 = 1 (coordinates of point T)

x2 = -1, y2 = 1 (coordinates of point I)

Plugging these values into the formula, we have:

Distance = √((-1 - (-5))² + (1 - 1)²)

        = √(4² + 0²)

        = √(16 + 0)

        = √16

        = 4

Therefore, the distance between point T (-5, 1) and point I (-1, 1) is 4 units.

The y-intercept is the point of (0,y) thus y-intercept of y = 2x + 1 is 1 and it is equal to the given graph of the function.

A graph is a diametrical representation of any function between the dependent and independent variables.

For example y = x² form a parabola now by looking at only the graph we can predict that it has only a positive value irrespective of the interval of x.

As per the given function,

y = 2x + 1

For y-intercept x = 0

y = 2(0) + 1 = 1

Thus, the y-intercept is 1.

In the graph, the line passes the y-axis at y = 1.
