The last option which says the roots of the auxiliary equation are √6 and -√6 is the correct one.
What are Auxiliary Equations?Auxiliary equation is the equation of characteristic polynomial which is calculated by substituting the right member of a standard differential equation by zero.
The roots of the equation is helpful in determining the nature of the general solution of the given differential equation.
We have the differential equation given in the question,
d²y / dx² - 6y = 0
Now we can replace d²y / dx² as y''.
y'' - 6y = 0, where y'' is the second derivative of y.
Now we have to find the roots of the auxiliary equation.
Let c = y', then c² = y''
c² - 6 = 0
c² = 6
c = +√6 and -√6
So the roots of the equation are √6 and -√6.
Hence the roots of the auxiliary equation of the differential equation given are +√6 and -√6.

Put the numbers in order from least to greatest.
Answer:
0.6 > 0.49 > 0 > -0.2 > -0.32
Step-by-step explanation:
-0.32 is the smallest number because it is farthest to the left of 0.-1/5 is the same thing as -0.2. Therefore it is the second smallest number because it is greater than -0.32 but smaller than zero. 0 belongs in the middle because it has no value and is a neutral number. 0.49 is greater than 0 so it should go to the right of zero. 6/10 is the same thing as 0.6. 0.6 is the greatest number of all these numbers so it should be the farthest to the right from 0.Please let me know if this helped!!!
The price for printing a small photo is $0.19. If the cost per square inch stays constant, how much should the large version of that photo cost, whose dimensions are 140% of the original?
Explain please!!
The cost of the large version of the photo is $0.456.
What is the cost?
Percentage is the fraction of an amount that is expressed as a number out of hundred. The sign that is used to represent percentage is %.
Cost of the large version of the photo = cost of the small photo x (1 + percent/100)
Cost of the large version of the photo = $0.19 x (1 + 140/100)
= $0.19 x (1 + 1.40)
= $0.19 x 2.40

The expected value for the given data set is 1.4.
What is expected value?
The value that will most likely be obtained from the following iteration of a statistical experiment is known as the expected value. In order to calculate the expected value for a random trial of an experiment, the probability of each possible result is taken into account.
From the given table we have to find the expected value.
Since,
Expected value = E(X) = μ = ∑ x*P(x)
E(X) = (0*0.4) + (1*0.05) + (2*0.3) + (3*0.25)
E(X) = 0 + 0.05 + 0.6 + 0.75

what is proportionality ?Relationships that always have the same ratio are said to be proportional. For instance, the number of trees in an orchard and the number of apples in a harvest of apples are determined by the average number of apples per tree. A linear relationship between two numbers or variables is referred to as proportional in mathematics. When the first quantity doubles, the other number does as well. When one of the variables is reduced to 1/100th of its previous value, the other also decreases. If two quantities are proportional, it means that when one rises, the other rises as well, and the ratio between the two quantities remains constant throughout all values. The diameter and circumference of a circle serve as an example.

The trigonometric function y = sin(3x + π) = 0 for -π/3 ≤ x ≤ π/3.
What is a trigonometric function?A trigonometric function is a function that uses one of the trigonometric ratios.
How to find the possible values of the trigonometric function?Given that we have the trigonometric function y = sin(3x + π) for -π/3 ≤ x ≤ π/3.
To find the range of output values for the range of input values given, we insert the given values of the input into the equation.
So, for the minimum value of y, we substitute x = -π/3 into the equation.
So, y = sin(3x + π)
y = sin(3(-π/3) + π)
y = sin(-π + π)
y = sin(0)
y = 0
For the maximum value of y, we substitute x = π/3 into the equation.
So, y = sin(3x + π)
y = sin(3(π/3) + π)
y = sin(π + π)
y = sin(2π)
y = sin2π
y = 0
So, y = 0 for -π/3 ≤ x ≤ π/3.

Side a of the oblique triangle is 25.57 units and side b is 9.42 units.
What is the law of sines?The number of sides of a triangle and how their individual sine angles are equal are determined by the law of sines. Other names for the sine law are sine rule, sine formula, and sine law. The law of sine is used to determine the side or unknown angle of an oblique triangle.
Given:
∠A = 107
∠B = 21
∠C = 52
c = 21
So, using the law of sines
b/sin B = c/ sin C
b/sin 21 = 21/sin 52
b = (21 × sin 21) / sin 52
= (21 × 0.35) / (0.78)
b ≈ 9.42
Similarly, side a of the triangle is given by
a/ sin A = c/ sin C
a/sin 107 = 21/sin 52
a = (21 × sin 107) / sin 52

tomatoes to make spaghetti sauce, how many batches of soup can
Fabian make? Write and solve an equation.
There will be a total of 3 batches of soup can Fabian make.
Explain how to calculate the total weight of ingredients needed for making a specific number of batches of a recipe.
To calculate the total weight of ingredients needed for making a specific number of batches of a recipe, you can multiply the weight of each ingredient per batch by the number of batches you want to make. This will give you the total weight of ingredients needed for the desired number of batches. For example, if a recipe requires 1 pound of flour per batch and you want to make 3 batches, the total weight of flour needed is 1 pound per batch * 3 batches = 3 pounds.
To find out how many batches of soup Fabian can make, we need to divide the total weight of tomatoes by the weight of tomatoes used per batch of soup.
Let x be the number of batches of soup Fabian can make. We know that:
10 pounds of tomatoes - 2.8 pounds of tomatoes = 7.2 pounds of tomatoes are available to make soup
The weight of tomatoes used per batch of soup is 2 2/5 pounds, we can write this as:
x * 2.4 = 7.2
To find the number of batches of soup Fabian can make, we can divide both sides by 2.4
x = 7.2/2.4
x = 3
So Fabian can make 3 batches of soup.

What is probability?The likelihood that an event or several events will occur is known as probability. Utilizing a straightforward formula, probability can be determined and is used to describe the likelihood of obtaining a specific result.Probability can alternatively be defined as the ratio of the number of expected outcomes of an event to its likelihood of occurring. When there are several events, the probability is calculated by dividing each likelihood into a single computation, multiplying the results, and then summing the results to determine the probability of each event.The probability of an event happening is defined by the probability formula. The proportion of favorable outcomes to all possible outcomes serves as the basis for the formula used to determine an event's probability. Always between 0 and 1 are the possible outcomes.
