1. The statement is false, as the differential equation is of the second order but it is nonlinear.
2. The statement is false, as the differential equation is linear.
3. The third statement is correct, as the differential equation is of the fourth order and nonlinear.
How to classify the differential equations?Regarding to linearity, the differential equations are classified as follows:
Linear: the derivatives of y are multiplied only by terms that do not contain the variable y.Non-linear: the derivatives of y are multiplied by terms that contain the variable y.Regarding the order, it is given by the order of the highest derivative in the differential equation.
For question 1, the differential equation y''y + (y')² = sin(x) is in fact of the second order, as the highest derivative is y'' (second derivative), but it is nonlinear, due to the multiplication of y by y''.
Hence the differential equation for question 2 is linear, as the multipliers to the derivatives are of x and -1, neither of which contains the variable y.
For question 3, we have that:
The differential equation is of the fourth order, as y''' x y' = y''''.The differential equation is nonlinear, due to the multiplication of y by xy'''.More can be learned about differential equations at https://brainly.com/question/18760518

A large rectangular prism is 12 inches long, 9 inches wide, and 6 inches tall. A small rectangular prism is also 12 inches long, but it's only 3 inches wide and 3 inches tall.
How many small prisms would it take to fill the large prism?
The required number of small prism that would be fill in the large prism is given as 6
As mentioned in the question, a large rectangular prism is 12 inches long, 9 inches wide, and 6 inches tall. A small rectangular prism is also 12 inches long, but it's only 3 inches wide and 3 inches tall.
Here,
The volume of the large prism = 12 × 9 × 6
= 648 inches cube
The volume of the small prism = 12 × 3 × 3
= 108 inches cube,
The ratio of the volume of the large prism to a small prism will give the number of small prisms needed to fill the large prism. So,
n = 648 / 108 = 6 / 1
Thus, the required number of small prism that would be filled in the large prism is given as 6.

Are there any circles for which the relationship between the diameter and the circumference cannot be represented by π? explain
Well, the diameter and circumference scale perfectly. Therefore, the ratio will remain the same regardless of how big or tiny the circle is. For all circles, circumference is equal to x diameter. There are no exceptions because this is the definition of.
Give an example of diameter.
If you look at the cycle wheel, the spikes that run through the center from one end to the other are an illustration of diameter. This is comparable to a circle's diameter, which is a line segment that extends from one end of the circle to the other end while passing through the center.

Determine the end behavior of the polynomial function.
f(x)= -2x^3 +3x^2 +2x -1
The correct option is (a)
As x ⇒ ∞, f(x) ⇒ -∞ and As x ⇒ -∞, f(x) ⇒ ∞.
What is Polynomial function ?
The terms poly and nomial combine to form the word polynomial. We can define polynomials as "algebraic expressions with many terms" because "poly" means many and "nomial" denotes the term.
Given : f(x)= -2x^3 +3x^2 +2x -1
In order to determine the end behavior of the polynomial function, we are required to check the highest degree of the polynomial and the coefficient of the term which has highest degree.
Here, The highest degree of the polynomial is 3 and the coefficient of the term which has highest degree is -2.
Since, the coefficient is negative, the graph will move right down which means as x ⇒ ∞, f(x) ⇒ -∞.
Similarly, the degree is odd which states that the sign will be opposite of what the coefficient has. So, As x ⇒ -∞, f(x) ⇒ ∞.
Hence, As x ⇒ ∞, f(x) ⇒ -∞ and As x ⇒ -∞, f(x) ⇒ ∞.

Which expression is equal to 7 + 6X5-2?
A) 13X5-2
B) 7+11-2
C) 13 X 3
D) 37-2
Answer:
So, in the expression 7 + 6X5-2, we must first multiply 6 and 5, which gives 30. Then we must add 7 and 30, which gives 37. Finally, we must subtract 2 from 37, which gives a final score of 35.
Therefore, the expression 7 + 6X5-2 is equal to 37-2. The correct answer is D) 37-2.

The z-score such that the area under standard normal curve to its left is 0.2 is found as -0.84.
Explain the term Z-score?A mathematical table known as the Z table, also known as the Z-score table or the standard normal table, is used to determine the likelihood that the z-score number is below, above, or in between the values just on standard normal distribution.
Z-scores are the most used name for standard scores. Its similar concepts, like as z-values, standardized factors, and normal scores, are utilized in this article.A positive Z score score implies that the raw score is higher than the distribution's mean.For instance, a z-score of 2 indicates that the result is two standard deviations above the mean.If the Z score is negative, the distribution's mean is below the raw score value.For the stated question,
You simply need to discover the location of 0.2 on the z-score table and then its z-score. (The area to the left of a z-score is shown in the table)
