If the original point in problem 12 first had
been reflected across the y-axis and then
across the x-axis, how would the third
point differ from the one above?

Considering the definition of zeros of a function, the time the ball remains in the air is 1.5 seconds.

The points where a polynomial function crosses the axis of the independent term (x) represent the zeros of the function.

Then, the zeros of a function are those values ​​of x for which the expression is equal to 0, and they correspond to the abscissa of the points where the parabola intersects the x-axis.

Considering the function h= -16t² +36, to calculate the time that the ball remains in the air, I must consider when the height is zero. That is, I must calculate the zeros of the function:

-16t² +36= 0

Solving:

-16t² = -36

t² = (-36)÷ (-16)

t²= 2.25

t=√2.25

t= ±1.5

Since time cannot be negative, the time the ball remains in the air is 1.5 seconds.

The value of m by using the Law of Cosines is 586.72​

We are given that;

In triangle whose side are 13in and 20in angle between those lines is 93degree.

Now,

The Law of Cosines states that for any triangle with sides a, b, and c and angle C opposite to side c, the following equation holds:

c^2=a^2+b^2−2abcosC

We want to find c, which is the same as m. So we plug in the given values into the equation and solve for c:

c^2=13^2+20^2−2(13)(20)cos93

c^2=169+400−520cos93

c^2=569−520(−0.0523)

c^2=586.72

The value of x that satisfies the equation √3x + 4 = 6 is x = 4/3.

To solve the equation √3x + 4 = 6, we'll need to isolate the variable x. Let's go through the steps to find the solution:

Subtract 4 from both sides of the equation:

[tex]\sqrt{3x}[/tex] + 4 - 4 = 6 - 4

[tex]\sqrt{3x }[/tex]= 2

Square both sides of the equation to eliminate the square root:

[tex](\sqrt{3x)^2} = 2^{-2}[/tex]

3x = 4

Divide both sides of the equation by 3 to solve for x:

(3x)/3 = 4/3

x = 4/3

Therefore, the solution to the equation √3x + 4 = 6 is x = 4/3.

By substituting x = 4/3 back into the original equation, we can verify if it is indeed a solution:

√3(4/3) + 4 = 6

2 + 4 = 6

6 = 6

The equation holds true, confirming that x = 4/3 is the correct solution.

Eigenvalues of A: λ1 = 8√2, λ2 = -8√2  Algebraic multiplicities: m1 = 1, m2 = 1

tr(A) = 0 (trace of A)

det(A) = -128 (determinant of A)

Let the eigenvalues be λ1 and λ2.

The trace of a matrix is the sum of its diagonal elements. Since tr(A) = 0,

The sum of the eigenvalues is zero: λ1 + λ2 = 0 (equation 1)

The determinant of a matrix is equal to the product of its eigenvalues.

Since det(A) = -128,

λ1 × λ2 = -128 (equation 2)

From Equation 1,

λ2 = -λ1

Substituting this into equation 2 we get

λ1 × (-λ1) = -128

- λ1² = -128

λ1² = 128

λ1 = ±√128

λ1 = ± 8√2

Since λ2 = -λ1,

λ2 = ± (-8√2) = ∓ 8√2

Therefore, the eigenvalues of matrix A are ±8√2, and each eigenvalue has an algebraic multiplicity of 1 .

Creation of unstable states: The borders established by Britain and France created new nation-states, such as Iraq, Syria, Lebanon, Jordan, and Palestine, without taking into account the underlying political, ethnic, and religious dynamics.

The logistic differential equation for these data is [tex]\frac{dP}{dt}\, =\, 0.0013P(1-\frac{P}{5900})[/tex]

The logistic differential equation is a mathematical model used to describe the growth of a population when there is a limiting factor that affects the growth rate. It is based on the idea that the growth rate of the population decreases as it approaches a maximum capacity or carrying capacity.

The equation is typically written as:

dP/dt = rP(1 - P/K)

where dP/dt is the rate of change of the population over time, P is the population size at any given time, r is the intrinsic growth rate, and K is the carrying capacity.

In the given problem, the carrying capacity is 5900, which means that the population cannot exceed 5900 individuals. The growth rate is given by k = 0.0013 per year. Thus, the logistic differential equation can be written as:

dP/dt = 0.0013P(1 - P/5900)

This equation represents the rate at which the population grows over time, taking into account the limiting factor of the carrying capacity. The solution to this differential equation can be used to predict the population size at any future time, given the initial population size and the growth rate.

Therefore, we have: sin() = -√(57/121) = -3√57/11 , To find the other trigonometric functions, we can use the definitions: tan() = sin()/cos() = (-3√57/11)/(8/11) = -3√57/8

The given information is that cos() = 8/11 and sin() is negative. From this, we can use the Pythagorean identity to solve for sin():

sin²() = 1 - cos²() = 1 - (8/11)² = 1 - 64/121 = 57/121

Since sin() is negative, we know that it must be in the third or fourth quadrant, where the sine function is negative. To determine which quadrant exactly,

we can use the fact that cos() is positive and recall that cosine is also positive in the first quadrant. Since cosine decreases as we move to the right, we know that angle must be in the fourth quadrant, where cosine is positive and sine is negative.

Therefore, we have:

sin() = -√(57/121) = -3√57/11

To find the other trigonometric functions, we can use the definitions:

tan() = sin()/cos() = (-3√57/11)/(8/11) = -3√57/8

csc() = 1/sin() = -11/(3√57)

What is a sequence?

A sequence is an enumerated collection of objects in which repetitions are allowed. Like a set, it contains members (also called elements, or terms).

We can find the correct nth term formula for the given sequence by analyzing the pattern of the terms.

Starting from the first term, 78, we see that each successive term is obtained by subtracting 12.5 from the previous term.

Therefore, the sequence is a linear sequence with a common difference of -12.5.

The nth term formula for a linear sequence with first term a1 and common difference d is given by:

aₙ = a1 + (n-1)d

Applying this formula to the given sequence, we have:

a₁ = 78 (the first term)

d = -12.5 (the common difference)

Therefore, the nth term formula for the sequence is

aₙ = 78 - 12.5(n-1)

What is the triangle?

A triangle is a three-sided polygon made up of three line segments that connect at three endpoints, called vertices. The study of triangles is an important part of geometry, and it has applications in various fields such as engineering, architecture, physics, and computer graphics.

Let's use the fact that the product of two segments of the same line through a point is equal:

AOOD = BOOE

We also have the equation:

AD + BE = 35

Using the fact that triangles AOD and BOE are similar (because they share angle AOB), we can write:

OD / OE = AO / BO = 9 / 12 = 3 / 4

We can use the fact that OD = (35 - BE) and OE = (35 - AD) to eliminate AD and BE:

AOOD = BOOE

9(35-BE) = 12(35-AD)

315 - 9BE = 420 - 12AD

AD + BE = 35

Solving these two equations simultaneously, we get:

AD = 15 dm

BE = 20 dm

Substituting into the expressions for OD and OE, we get:

OD = 20 dm

OE = 15 dm

Therefore, OD = 20 dm and OE = 15 dm.

Yes, it appears that the data are normally distributed. This is because the standard deviation (2.45 grammes) and the mean (20 grammes) both fall within acceptable bounds.

Since the data points are evenly spaced from the mean, the distribution is symmetric and corresponds to a normal distribution. The standard deviation is also not excessive in comparison to the mean, supporting the notion that the data is regularly distributed.

A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

In contrast, a high or low standard deviation indicates that the data points are, respectively, above or below the mean. A standard deviation that is close to zero implies that the data points are close to the mean.

Therefore, company A will charge less than company B for any mileage greater than 65 miles.
To help you with your question, I need the specific prices for both companies, as well as any additional information you can provide about the charges.

To solve for the mileages at which company A will charge less than company B, we can set up the following inequality:
A < B
where A is the cost of renting from company A and B is the cost of renting from company B. We can plug in the given information to get:
x ≤ A
x > B = y + 40z
where x is the number of miles driven, y is the initial fee for company B, and z is the additional cost per mile for company B.
Now we can substitute the given values to get:
x ≤ A
x > y + 40z
For company A, the cost is a flat rate with unlimited mileage, so A is just the cost listed for one day of rental. Let's say that cost is $100.
For company B, the initial fee is $50 and the additional cost per mile is $0.25. So:
y = 50
z = 0.25
