Solve the equation: r - 535 = 175

The orthocenter of the triangle with vertices  P(-1,2), Q(5,2), R(2,1) is

Orthocenter is calculated by

formula for slope is

m = (y₂ - y₁) / (x₂ - x₁)

slope of the perpendicular = -1/m

Using side PR  P(-1,2)  R(2,1) ,

m = (1 - 2) / (2 - -1)

m = 1 / 3

slope of the perpendicular = -1/m = - 1 / (1/3) = -3

using point-slope formula for equation of line passing through Q (5, 2)

point slope formula

(y - y₁) = m (x - x₁)

(y - 5) = -3 (x - 2)

y - 5 = -3x + 6

y = -3x + 6 + 5

y = 11 - 3x

Using side PQ  P(-1, 2), Q(5, 2)

m = (2 - 2) / (5 - -1)

m = 0

slope of horizontal line is zero for horizontal line the perpendicular is a vertical line

using point-slope formula for vertical line passing through R (2, 1)

point slope formula

(y - y₁) = m (x - x₁)

0 = (x - 2)

x =  2

The two equations are

y = 11 - 3x

x = 2

solving both equations with x already known

y = 11 - 3 * 2

y = 11 - 6

y = 5

Therefore the orthocenter is (2, 5)

Answer:

3x^2-2x+3+1/x+2

Step-by-step explanation:

The graph which represents the polynomial function f(x) = x^3 - 2x^2 - 5x + 6 is in option A.

First, let us understand the polynomial function:

A polynomial function is one that uses only non-negative integer powers or positive integer exponents of a variable in an equation such as the quadratic equation, cubic equation, and so on. For example, 9y + 6 is a polynomial with an exponent of 1.

We are given:

f(x) = x^3 - 2x^2 - 5x + 6

We know that, when the graph intersects the x-axis, it satisfies the equation that is f(x) = 0 at that point.

Let us check the points one by one;

Option A;

The graph intersects the x-axis at -2, 1, and 3 it should satisfy the equation f(x) = 0.

Let's put x = -2 in f(x), we will get;

f(-2) = -2^3 - 2(-2)^2 - 5(-2) + 6 = -8 - 8 + 10 + 6 = -16 + 16 = 0

f(-2) = 0.

Let's put x = 1 in f(x), we will get;

f(1) = 1^3 - 2(1)^2 - 5(1) + 6 = 1 - 2 - 5 + 6 = 7 - 7 = 0

f(1) = 0.

Let's put x = 3 in f(x), we will get;

f(3) = 3^3 - 2(3)^2 - 5(3) + 6 = 27 - 18 - 15 + 6 = 33 - 33 = 0

f(3) = 0.

So, the points -2, 1, and 3 satisfy the equation f(x).

Thus, the graph which represents the polynomial function f(x) = x^3 - 2x^2 - 5x + 6 is in option A.

An eight pointed star have 8 rotational symmetry and 8 reflection symmetry

The rotational symmetry of a shape explains why an object's shape remains unchanged when rotated about its own axis.

The eight pointed star while standing on any of the edges will be symmetrical.

Symmetry with respect to reflections is known as reflection symmetry. Mirror or line symmetry are other names for reflection symmetry.

For a reflection symmetry to be in a figure, the figure must at least have one line dividing it into two parts, one of which is the mirror image of the other,

Option A is the correct answer g(x) = |x+3| by using the relation with the parent function.

Explain absolute value function.

A function that wraps an algebraic expression in absolute value symbols is known as an absolute value function. Remember that a number's distance from 0 on the number line represents its absolute value.

The definition of the absolute value parent function, f(x)=| x |, is as follows:

f(x) = [tex]\left \{ {{x ~, ~ x > 0} \atop {0 ~ , ~x = 0}} \atop {-x ~, ~x < 0} \right.[/tex]

Given parent function is f(x) = |x|

g(x) is obtained by stretching the graph of f(x) by a factor of 3.

Use the function g(x)=f(x−h) to translate the absolute value function f(x)=| x | horizontally.

The graph of f(x) is moved h units to the right to obtain g(x) for h>0

The graph of f(x) is translated h units to the left to obtain g(x) when h>0

Therefore, g(x) = |x+3|

If the dairy farmer wants to mix a 80% protein. The amount of pounds of each that he should use is 80% 280 pounds and 55% 1120 pounds.

Protein I 80% = x pounds

Protein II 55% = 1400 - x pounds

Mixture 60% = 1400

Hence,

80% x + 55% ( 1400 - x ) = 60% × 1400

80 x + 55 ( 1400 - x ) = 84000

80 x + 77000 - 55 x = 84000

Combine like terms

80 x - 55 x = 84000 - -77000

25 x = 7000

Divide both side by 25x

x= 7000/25

x =280 pounds ( Protein I)

Protein II

1400 - x pounds

1400 -280

=  1120 pounds

Therefore the farmer should use 280 pounds and 1120 pounds.

The degree and number of unique zeros of f(x) = (x – 5)(x + 3)(x – 1)² is:

Degree: 4; number of unique zeros: 3.

The end behavior of the polynomial is:

As x → –∞, f(x) → ∞ and as x → ∞, f(x) → ∞.

The degree of the polynomial function is given by the sum of the multiplicities of the roots.

These roots are given as follows:

Hence the degree is:

1 + 1 + 2 = 4.

The unique zeros are the roots, hence there are three unique zeros, which is the same number of linear factors of the function.

The end behavior is the limit of the function as x goes to negative infinity and to positive infinite, hence:

In the question:

ABCDEFGHIJ is a regular decagon. It rotates clockwise about its center to form the polygon A'B'C'D'E'F G'HIJ.

To find the each angle of rotation to the point A' coincides with after that rotation.

Now, According to the question:

let's know about Decagon:

A decagon is a ten-sided polygon or 10-gon. The total sum of the interior angles of a simple decagon is 1440°. A self-intersecting regular decagon is known as a decagram.

Every regular polygon with n sides can be divided into n  congruent triangles. The angle with vertex the center of the polygon will measure

360 : n degrees.  We are given a regular decagon, therefore:

n = 10

α = 360 : n = 36°

We consider that, if the decagon is not rotated, A' coincides with A and the rotation is towards the next letter of the alphabet. This means that after one rotation of 36° A' will coincide with B, after two rotations A' will coincide with C and so on.

A' will coincide with D after three rotations: 3 × 36° = 108°

A' will coincide with F after five rotations: 5 × 36° = 180°

The slope of a line KH if H(-4, 2) and K(2, -2) is -2/3.

A mathematical word used to define a line's direction and steepness is its slope or gradient.

If a line is rising from left to right, it is growing. The slope is positive, or m>0

If a line decreases from left to right, it is said to be diminishing. The slope is negative, indicating that m < 0

A line has zero slopes if it is horizontal. This function is constant.

The slope of a line is y - y₁ = m(x - x₁)

Slope m = (y₂ - y₁)/(x₂ - x₁)

The number that is closest to the mean of the distribution is 4 (option C)/

A histogram is used to represent data graphically. The histogram is made up of rectangles whose area is the product of the frequency of the rectangle and the width of the rectangle.  

Mean is the average of a set of numbers. It is determined by multiplying each bar in the histogram by its height, add the multiplication value for all the bars together and dividing it by the total frequency of the bars.

Mean = [(1 x 1) + (2 x 2) + (3 x 3) + (4 x 4) + (5 x 3) + (6 x 2) + (7 x 1)] / (1 + 2 + 3 + 4 + 3 + 2 + 1)

The probability that the mean actual weight for the 100 weights is greater than 25.2 is equal to 0.0136%.

In order to determine the probability that the mean actual weight for the 100 weights is greater than 25.2, we would have to calculate the mean and standard deviation.

In a uniform distribution, the mean of a data set can be calculated by using this formula:

Mean, E(x) = [a + b]/2

Where:

Substituting the given parameters into the formula, we have;

Mean, E(x) = [24 + 26]/2

Mean, E(x) = 50/2

Mean, E(x) = 25.

For the standard deviation, we have:

Standard deviation, S(x) = √((b - a)²/12)

Standard deviation, S(x) = √((26 - 24)²/12)

Standard deviation, S(x) = √((2)²/12)

Standard deviation, S(x) = √(4/12)

Standard deviation, S(x) = 0.5774.

For the sample standard deviation, we have:

Standard deviation = S(x)/√n

Standard deviation = 0.5774/√100

Standard deviation = 0.5774/10

Standard deviation = 0.05774.

By applying the central limit theorem, we would determine the z-score as follows:

Z-score = (x - μ)/σ

Z-score = (25.2 - 25)/0.05774

Z-score = 0.2/0.05774

Z-score = 3.64

Therefore, the p-value is equal to 0.000136.

Probability (x > z) = 0.0136%.
