Answer: HJ and JH

Step-by-step explanation:

Basically just name the letters in both ways that you can. the symbol would be a line above them since this is a side or line.

so like: (look at the picture)

hope this helps! :)

HJ and JH is the two representation of the given line segment.

A line section that can connect two places is referred to as a segment.

In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.

The line is here! It extends endlessly in both directions and has no beginning or conclusion.

A line segment can be represented in two ways one is either one end to another and the second is opposite to the other.

The denotation of a line segment let's say AB is representing the length of the line segment.

And length can never change by measuring either one end or another.

So HJ and JH are two ways to represent the line segment.

Hence "HJ and JH is the two representation of the given line segment".

Answer:

6 hours

Step-by-step explanation:

Let both of them plan for  t hours to plant 111 trees n t hours

Melissa  can plants 10 trees in 1 hour

in t hours she can plant 10 t trees

Jane plants 17 tree in 2 hours

in one hour Jane can plant 17/2 trees

in t hours she can plant (17/2)t  trees.

Total trees planted by both of them in t hours in terms of t will be

10t + (17/2)t

= (10t*2 + 17t)/2

= (20t + 17t)/2

= 37t/2

but it is given that they planted 111 trees together

so 37t/2 should be equal to 111

37t/2 = 111

=> 37t = 111*2 = 222

=> t = 222/37 = 6.

Thus, it takes 6 hours for both of them to plant 111 trees together.

Imagine that a survey of randomly selected people finds that people who used sunscreen were more likely to have been sunburned in the past year.

There are several possible explanations for the finding that people who used sunscreen were more likely to have been sunburned in the past year.

However, without additional context or data, it is difficult to determine the most likely explanation definitively. Here are a few possible explanations to consider:

1. Ineffective or improper use of sunscreen: It is possible that the individuals who reported using sunscreen did not apply it correctly or did not reapply it as recommended.

Inadequate application or failure to follow proper sunscreen usage guidelines could result in insufficient protection from the sun's harmful rays, leading to sunburn.

2. Self-selection bias: It is possible that individuals who have previously experienced sunburns may be more likely to use sunscreen. They may be more aware of the potential risks and take precautions, including using sunscreen.

This could create an association between sunscreen use and sunburn, even though sunscreen itself is intended to prevent sunburn.

3. Recall bias: The survey responses may be subject to recall bias, where individuals may inaccurately remember or report their sunscreen use and sunburn experiences.

Memory limitations or subjective perceptions of sunburn severity could influence the reported data and the observed association between sunscreen use and sunburn.

4. Confounding factors: There may be other factors or variables at play that are related to both sunscreen use and sunburn. For example, individuals who engage in activities that increase sun exposure or who have certain skin types may be more likely to both use sunscreen and experience sunburn.

It is important to note that further investigation, including more detailed surveys, data collection and statistical analysis, would be necessary to determine the most likely explanation for the observed association between sunscreen use and sunburn.

(b)To solve the differential equation, we have to find the roots of the characteristic equation. So, the characteristic equation of the given differential equation is: r² + r = 0. Therefore, we have the roots r1 = 0 and r2 = -1. Now, we can write the general solution of the differential equation using these roots as: y(t) = c₁ + c₂e⁻ᵗ, where c₁ and c₂ are constants. To find these constants, we need to use the initial conditions given in the question. y(0) = 1, so we have: y(0) = c₁ + c₂e⁰ = c₁ + c₂ = 1. This is the first equation we have. Similarly, y'(t) = -c₂e⁻ᵗ, so y'(0) = -c₂ = 0, as given in the question. This is the second equation we have.

Solving these two equations, we get: c₁ = 1 and c₂ = 0. Hence, the general solution of the differential equation is: y(t) = 1. (c)Now, we can use the result obtained in part (b) to solve the initial value problem y" + y' = 2t with y(0) = 1 and y'(0) = 0. We can rewrite the given differential equation as: y" = 2t - y'. Substituting the general solution of y(t) in this equation, we get: y"(t) = -e⁻ᵗ, y'(t) = -e⁻ᵗ, and y(t) = 1. Therefore, we have: -e⁻ᵗ = 2t - (-e⁻ᵗ), or 2e⁻ᵗ = 2t, or e⁻ᵗ = t. Hence, y(t) = 1 + c³, where c³ = -e⁰ = -1. Therefore, the solution of the initial value problem is: y(t) = 1 - t.

Part (b) of the given question has been solved in the first paragraph. We have found the roots of the characteristic equation r² + r = 0 as r₁ = 0 and r₂ = -1. Then we have written the general solution of the differential equation using these roots as y(t) = c₁ + c₂e⁻ᵗ, where c₁ and c₂ are constants. We have then used the initial conditions given in the question to find these constants.

Solving two equations, we got c₁ = 1 and c₂ = 0. Hence, the general solution of the differential equation is y(t) = 1.In part (c) of the question, we have used the result obtained from part (b) to solve the initial value problem y" + y' = 2t with y(0) = 1 and y'(0) = 0. We have rewritten the given differential equation as y" = 2t - y' and then substituted the general solution of y(t) in this equation. Then we have found that e⁻ᵗ = t, which implies that y(t) = 1 - t. Therefore, the solution of the initial value problem is y(t) = 1 - t.

So, in conclusion, we have solved the differential equation y" + y' = 2t and the initial value problem y" + y' = 2t with y(0) = 1 and y'(0) = 0.

Using the remainder theorem, the value of P(3) for the polynomial P(x) = 2x^4 - 4x^3 - 4x^2 + 3 is 48. The quotient and remainder for the associated division are not required.

Explanation:

The remainder theorem states that if a polynomial P(x) is divided by x - a, then the remainder is equal to P(a).

In this case, we want to find P(3), which means we need to divide the polynomial P(x) by x - 3 and find the remainder.

Performing the division, we get:

        2x^3 - 10x^2 - 22x + 57

x - 3 ) 2x^4 - 4x^3 - 4x^2 + 3

        2x^4 - 6x^3

                    2x^3 - 22x^2

                    2x^3 - 6x^2

                              -16x^2 + 3

                              -16x^2 + 48x

                                        45x + 3

                                        45x - 135

                                                 138

Therefore, the remainder is 138, and P(3) = 138. The quotient is not necessary for finding P(3).

The probability expression is n/10 * (n - 1)/9 and the single fraction is n(n - 1)/90

We understand that there are 10 sweets in the box

Such that

Jelly beans = n

This means that

The rest = 10 - Jelly beans

So, we have

The rest = 10 - n

The probability of 2 jelly bean sweet is represented as

P(2 jelly bean sweets) = P(First jelly bean sweets) * P(Second jelly bean sweets)

The length of the straw is 3.74 inches.

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

In rectangular box,

Length (l) = 2 inches

Width (w) = 1 inches

Height (h) = 3 inches

Here, The straw is said to fit into the box diagonally from the bottom.

So, the length (s) of the straw is calculated as:

⇒ s = √ l² + w² + h²

⇒ s = √ 2² + 1² + 3²

⇒ s = √ 4 + 1 + 9

⇒ s = √ 14

⇒ s = 3.74 inches

The general solution for the third-order homogeneous Cauchy-Euler differential equation with roots m1=-1, m2=-1, and m3=2 is y(x) = \(c_{1}x^{-1} + c_{2}x^{-1}ln(x) + c_{3}x^{2}\).

The characteristic equation for the given differential equation is (m + 1)^2(m - 2) = 0. Solving this equation gives us the roots m1=-1, m2=-1, and m3=2. Since we have a repeated root of -1, we need to include an ln(x) term in our general solution.

Therefore, our general solution will have the form y(x) = c1x^m1 + c2x^m2ln(x) + c3x^m3. Substituting the values of the roots, we get y(x) = \(c_{1}x^{-1} + c_{2}x^{-1}ln(x) + c_{3}x^{2}\), which is the general solution to the given differential equation.

The constants c1, c2, and c3 can be determined by using initial or boundary conditions if provided.
