Answer: C. It has reflectional symmetry with five lines of symmetry.

The five lines of symmetry are shown in the diagram below. Each line splits a flower petal in half. Each line also splits the entire flower in half. In other words, reflecting one half of a flower over any given line of symmetry, generates the other half of the flower.

The correct answer is C. The given figure has reflectional symmetry with five lines of symmetry.

Symmetry refers to the property of an object remaining unchanged when certain transformations are applied to it.

A. Point symmetry, also known as rotational symmetry, means that the object looks the same when rotated by a certain angle around a central point. However, a given figure does not have point symmetry since it does not look the same when rotated by any angle around a central point.

B. The statement that the flower has rotational symmetry with an angle of rotation of 120° is incorrect because, as mentioned above, it does not possess rotational symmetry.

C. The flower does have reflectional symmetry with five lines of symmetry. This means that the flower can be divided into five equal parts using five lines of reflectional symmetry, such that each part is a mirror image of the other.

D. The statement that the flower has no rotational symmetry is correct, as mentioned in A and B.

Therefore, the correct answer is C. It has reflectional symmetry with five lines of symmetry.

there are two red 8's in a deck or cards (8 of hearts and 8 of diamonds). therefore the probablility is 2/52. in decimal form that is 0.04 (rounded).

Answer:

k=-3

Explanation:

Plug in x and y values

-40=k(14)+2

-2 both sidea

-42=k(14)

divide by 14 both sides

k=-3

k = -3

Step-by-step explanation:

y = kx + 2 through the point a(14, -40)

Subtitute…

y = kx + 2

-40 = k(14) + 2

-40 = 14k + 2

-40 - 2 = 14k

-42 = 14k

(-42)/14 = k

-3 = k

Let's simplify the expression step by step: Expand the squared term:

(x - 3y)² = (x - 3y)(x - 3y) = x² - 6xy + 9y²

Expand the second term:

3(x + y)(x − 4y) = 3(x² - 4xy + xy - 4y²) = 3(x² - 3xy - 4y²)

Expand the third term:

x(3x + 4y + 3) = 3x² + 4xy + 3x

Now, let's combine all the expanded terms:

(x - 3y)² + 3(x + y)(x − 4y) + x(3x + 4y + 3)

= x² - 6xy + 9y² + 3(x² - 3xy - 4y²) + 3x² + 4xy + 3x

Combining like terms:

= x² + 3x² + 3x² - 6xy - 3xy + 4xy + 9y² - 4y² + 3x

= 7x² - 5xy + 5y² + 3x

The simplified form of the expression is 7x² - 5xy + 5y² + 3x.

Chronic obstructive pulmonary disease (COPD) is a disease characterized by permanent airflow obstruction and extended periods of disability and restricted activity.

Chronic obstructive pulmonary disease (COPD) is a chronic respiratory condition that affects the lungs and airways. It is primarily caused by long-term exposure to harmful substances such as cigarette smoke, air pollution, and occupational hazards.

COPD is characterized by permanent airflow obstruction, which means that the airways become narrowed and it becomes difficult for air to flow in and out of the lungs. This obstruction leads to symptoms such as shortness of breath, persistent coughing, wheezing, and frequent respiratory infections.

The disease is progressive and can result in extended periods of disability and restricted activity, as the individual's lung function gradually declines over time. COPD requires long-term management and treatment to improve symptoms and prevent further deterioration of lung function.

Using differential equation the population of the mice is given by option e. None of the above and is equal to P = 6000 ( 3 + 7e^(-t/60) ).

Differential equation representing the population of mice is

(3000 /P) (dP/ dt) = 200 − P

⇒ 3000∫( 1 / P(200 - P) dP = ∫dt __(1)

Using partial differential we get,

( 1 / P(200 - P)  = ( A/ P) + B/ ( 200 -P)

⇒ A = -1/200 and B = 1/200

(1/200)[ ∫(1/P) dP - ∫dP/ (200 -P)

= (1/200)[ log P - log(200 -P)]

For P = 60

(1/200)[ log |P| - log|200 -P|]

= (1/200)[ log60 - log(200 -60)]

= (1/200) log(60/140)

= 1/200 log (3/7)

Substitute in (1) we get,

3000∫( 1 / P(200 - P) dP = ∫dt

= 3000 (1/200)[ log P - log(200 -P)] + c= t

t=0 , P(0) = 60

= 3000 [1/200 log (3/7)] + c = 0

⇒ c = - 60log(3/7)

Now,

60[log(P/200 -P) ] - 60log(3/7) = t

⇒60[ log(P /(200 -P)(3/7) ]= t

⇒P / (200 - P) = (3/7) e^(t/60)

⇒ P = 200(3/7) e^(t/60) - P((3/7) e^(t/60))

⇒P( 1 + (3/7) e^(t/60) ) =  200(3/7) e^(t/60)

⇒P = ( 6000)e^(t/60) / ( 7 + 3 e^(t/60) )

⇒P = 6000 ( 3 + 7e^(-t/60) )

Therefore, the function describes the population of the mouse using differential equation is equal to option e. none of the above and is equal to P = 6000 ( 3 + 7e^(-t/60) ).

Answer:

Not a quadratic function.

Step-by-step explanation:

A function is a relation wherein each input or x-value corresponds exactly to an output or y-value.  In other words, a relation is a function if there are no repeating x-values.  

A way to determine whether a given graph represents a function is to perform the Vertical Line Test.  Using the Vertical Line Test, we must draw vertical lines across the graph.  If each of the vertical lines drawn intersects the graph at exactly one point, then the relation is a function.  

⇒  The attached screenshot shows that the given graph fails the Vertical Line Test, as each vertical line drawn intersects the graph more than once. This means that those x-values correspond to more than one y-value. Specifically, x = 1 corresponds to the following y-values: y = -1 and y = 1.   Hence, the given horizontal parabola is not a quadratic function.

The given graph represents a horizontal (or sideways) parabola.

The vertex form of the horizontal parabola is: x = a(y - k)² + h.  

where:

a = Determines the direction of the graph's opening.

y = k is the horizontal axis of symmetry

k = determines the vertical translation of the graph

h = determines the horizontal translation of the graph

The vertex of the given graph occurs at the point of origin, (0, 0).

Let's use one of the given points on the graph, (1, 1), and substitute these values into the vertex form to solve for a :

x = a(y - k)² + h

1 = a(1 - 0)² + 0

1 = a( 1 )²

1 = a

Equation of the given horizontal parabola in vertex form:  

      ⇒     x = (y - 0)² + 0  or  x = y²

It is evident that in the vertex form of a horizontal parabola, the variable, y, is squared.

                          x = 1 has two y-values: y = -1, and y = 1.

                           x = 4 has two y-values: y = -2, and y = 2.

Thus, by definition of function, the given horizontal parabola is not a quadratic function, as it fails the vertical line test.

What is angle on a straight line?

A straight line's angles add up to 180 degrees.

You can calculate angles using this fact as well.

Add all known angles together to find the missing angle on a straight line.

Angle sum is subtracted from 180 degrees.

Create the equation, then resolve it.

Here the given two angles on a straight line are (24 - 4)° and (5t + 2)°.

Since the measure of straight line is 180°.

⇒  (2t - 4)° + (5t + 2)° = 180°

        2t - 4° + 5t + 2° = 180°

                       7t - 2° = 180°

                             7t = 180° + 2°

                              7t = 182°

                                t = 182°/7

                                t = 26°

Hence, the value of t for the given problem is 26°.

A hexagon

Step-by-step explanation:

A hexagon - - - the allen wrench has 2 hexagonal heads. See attached pic.

The geometric shape that forms the hole that fits an allen wrench is a hexagon, which is a six-sided polygon with straight sides and angles.

The geometric shape hexagon-shaped hole in an allen wrench, also known as a hex key, is designed to fit tightly over the hexagonal socket of a screw or bolt head. A hexagon is a six-sided polygon, meaning it has six straight sides and angles. In the case of an allen wrench, the hexagon has internal angles of 120 degrees and opposite sides that are parallel.

The hexagonal shape of the hole in the wrench allows for a tight and secure fit onto the corresponding hexagonal socket of the screw or bolt head. This design ensures that the wrench can apply a significant amount of torque to the fastener without slipping, which is essential for many applications in construction, mechanics, and other industries.

The use of a hexagonal shape also allows for greater precision and control when turning the screw or bolt, making it easier to achieve the desired level of tightness. Overall, the hexagon is an ideal shape for the hole in an allen wrench due to its strength, stability, and precision.

The point of rotation R is located at (1, -4).

We have,

To find the point about which triangle JKL was rotated to result in the coordinates (1, -4) for point L' on the rotated triangle J'K'L', we need to find a point equidistant from points L and L'.

Let's denote the point of rotation as R, and the coordinates of L as (x, y).

Since the point R is equidistant from points L and L', we can use the midpoint formula to find its coordinates.

The midpoint formula states that the coordinates of the midpoint between two points (x₁, y₁) and (x₂, y₂) are given by:

Midpoint = ((x₁ + x₂) / 2, (y₁ + y₂) / 2)

In this case, we have the coordinates of L as (x, y) = (x, y) and the coordinates of L' as (1, -4).

Using the midpoint formula, we can set up the following equation:

((x + 1) / 2, (y - 4) / 2) = (x, y)

Simplifying this equation, we get:

(x + 1) / 2 = x and (y - 4) / 2 = y

Solving the first equation, we have:

x + 1 = 2x

x = 1

Substituting this value back into the second equation, we get:

(y - 4) / 2 = y

y - 4 = 2y

y = -4

Therefore,

The point of rotation R is located at (1, -4).

Based on the zeros and the end behavior of the function, we can choose the graph that matches these characteristics. The graph should have x-intercepts at x = 0 (with multiplicity 3) and x = 1, and it should exhibit a rising behavior on both sides.

The given function f(x) = (x^3)(x^2)(x - 1) is a polynomial function. By analyzing the factors of the function, we can determine its zeros, which are the x-values where the function equals zero.

The zeros of the function occur when any of the factors equal zero. Setting each factor to zero, we find the following zeros:

x^3 = 0  --> x = 0

x^2 = 0  --> x = 0

x - 1 = 0  --> x = 1

Therefore, the zeros of the function are x = 0 (with multiplicity 3) and x = 1.

Now, let's consider the end behavior of the graph. As x approaches negative or positive infinity, we can determine the behavior of the function.

Since the highest power of x in the function is x^3, we know that the end behavior of the graph will match that of a cubic function. If the leading coefficient is positive, the graph will rise to the left and rise to the right. If the leading coefficient is negative, the graph will fall to the left and fall to the right.

In the given function, the leading coefficient is positive (since the coefficient of x^3 is 1). Therefore, the graph of the function will rise to the left and rise to the right as x approaches negative or positive infinity.

Based on the zeros and the end behavior of the function, we can choose the graph that matches these characteristics. The graph should have x-intercepts at x = 0 (with multiplicity 3) and x = 1, and it should exhibit a rising behavior on both sides.

The meaning of such an equations in algebra is just a mathematical expression stating the equality between two mathematical terms. For instance, 6x + 5 = 11 is an equation where 6x + 5 and 11 are two expressions separated by the 'equal' sign.

Identity equations and conditional equations are the two types of equations. For just any value of both the variables, an equality remains true. Only such variables have values that make a condition expression true. Two expressions joined by an equals sign ("=") form an equation.

Let, x, y and z are the three types of products.

In one year, the total revenue for the three products was $1,100,000, which corresponded to the sale of 54,000 units.

Thus, 30x + 20y + 10z = 1,100,000 ............ (i)

x + y + z = 54000 ............... (ii)

The company sold half as many units of the $30 product as units of the $20 product, so, x = y/2

putting this in equation (i)

thus, 30x + 20 (2x) + 10z = 1,100,000

70x + 10z = 1100000 ......... (iii)

next putting the value of y = 2x in equation (ii) we get -

3x + z = 54000......... (iv)

Solve this two equation we get -
