We are given a function y = -4x^3 - 9x^11, and we need to find its first and second derivatives.

To find the first derivative, we apply the power rule and the constant multiple rule. The power rule states that the derivative of x^n is nx^(n-1), and the constant multiple rule states that the derivative of kf(x) is k*f'(x), where k is a constant. Applying these rules, we can find the first derivative of y = -4x^3 - 9x^11.

Taking the derivative term by term, the first derivative of -4x^3 is -43x^(3-1) = -12x^2, and the first derivative of -9x^11 is -911x^(11-1) = -99x^10. So, the first derivative of y is dy/dx = -12x^2 - 99x^10.

To find the second derivative, we apply the same rules to the first derivative. Taking the derivative of -12x^2, we get -122x^(2-1) = -24x, and the derivative of -99x^10 is -9910x^(10-1) = -990x^9. Therefore, the second derivative of y is d^2y/dx^2 = -24x - 990x^9.

Answer:

Step-by-step explanation:

For students getting an A there are 5 out if 90 total. 5/90 is the fraction getting an A. The pie chart will be a whole entire circle, which is 360°.

So,

For A: 5/90(360) = 20°

For B: 15/90(360) = 60°

For C: 40/90(360) = 160°

For D: 20/90(360) = 80°

For E: 10/90(360) = 40°

Drawing the accurate pie chart, well, here's a tip-- remember you know what 90° looks like. In half, that's 45° or in three pieces its 30° . A straight line is 180° so use these guides and grow or shrink the angles to get the approximate sizes you need (20°, 60°, 160°, 80°, 40°)

Answer:

Sale price:  $722.50

Step-by-step explanation:

Subtract 15% from 100%, obtaining 85%.  The computer is sold for 85% off.

Converting this 85% to a mixed decimal, we get 0.85, and then we multiply the original price ($850) by this 0.85:  0.85($850) = $722.50

The product of a rational and an irrational number can be either rational or irrational, depending on the specific numbers involved.

To illustrate this, let's consider an example:

Let's say we have the rational number 2/3 and the irrational number √2.

Their product would be (2/3) * √2.

In this case, the product is irrational.

The square root of 2 is an irrational number, and when multiplied by a rational number, the result remains irrational.

However, it's also possible to have a product of a rational and an irrational number that is rational. For example, if we consider the rational number 1/2 and the irrational number √4, their product would be (1/2) * 2, which equals 1. In this case, the product is a rational number.

Therefore, we cannot make a definitive statement that the product of a rational and an irrational number is always rational or always irrational. It depends on the specific numbers involved in the multiplication.

Answer:

C

Step-by-step explanation:

Here, Statement a) B is more stable than A  is correct, while statements b), c), and d) are incorrect.

Lindane, also known as gamma-hexachlorocyclohexane, exists as a mixture of two stereoisomers. These stereoisomers have different chair conformations, often referred to as conformer A and conformer B. I will describe these conformations to help you analyze the statements provided.

Conformer A: In conformer A, one of the chlorine atoms is positioned in an axial (up) position, while the other five chlorine atoms are in equatorial (outward) positions. This arrangement is less stable due to steric hindrance caused by the axial chlorine atom, which experiences stronger interactions with neighboring groups.

Conformer B: In conformer B, the axial and equatorial positions of the chlorine atoms are interchanged compared to conformer A. The chlorine atom that was previously axial is now equatorial, and vice versa. This arrangement reduces the steric hindrance, leading to a more stable conformation.Now, let's analyze the provided statements:

a) B is more stable than A:

This statement is correct. Conformer B is indeed more stable than conformer A because it minimizes steric hindrance by placing the chlorine atoms in more favorable positions.b) A is more stable than B:

This statement is incorrect. As explained above, conformer B is more stable than conformer A.

c) A is not the correct representation of Lindane:

This statement is incorrect. Both conformers A and B are valid representations of Lindane, and the compound exists as a mixture of these conformations.

d) The two chair conformations of Lindane are degenerate:

This statement is incorrect. Degenerate conformations have the same energy level. In the case of Lindane, conformer B is more stable than conformer A, indicating that they have different energy levels and are not degenerate.

The child passes through 18π radians in the course of the carousel ride.

To determine the number of radians the child passes during the 6-minute ride on the carousel, we need to know the distance traveled in terms of radians.

Since there are 20 horses spaced evenly around the carousel, each horse is separated by an angle of 360/20 = 18 degrees or π/10 radians.

Therefore, during one rotation of the carousel, the child passes through 20π/10 = 2π radians. And since the carousel completes one rotation every 40 seconds, the angular velocity is 2π/40 = π/20 radians per second.

To find the total distance traveled in radians during a 6-minute ride, we need to multiply the angular velocity by the time elapsed.

6 minutes is equal to 360 seconds,

so the child passes through π/20 x 360 = 18π radians during the ride.

Answer:

x=120 and y=60

Step-by-step explanation:

As we know, a straight line is 180 degrees.

To find x, you would do 180= 60 + x to get 120.

I forget how but I know y= 60 because its the same angle as 60 degrees.

Answer:

i may be wroung but it should be 90

Step-by-step explanation:

Answer:

x=35

Step-by-step explanation:

The sum of angles in a triangle is equal to 180. In the triangle given, we have to add all the angles to find x.

So,

\(3x+x+40=180\)

to find x, we must isolate it:

combine common terms:

\(4x+40=180\)

subtract the 40 to both sides:

\(4x+40-40=180-40\)

divide by three to isolate the variable:

\(4x/4=140/4\)

and the resulting would be our x:

\(x=35\)

to check if our answers make sense, substitute.

\(3(35)+35+40=180\)

solve:

\(180=180\)

The perceptual constancy that recognizes objects despite changes in angle, distance, or illumination is shape constancy.

Shape constancy is a perceptual phenomenon where our brain recognizes and maintains the perceived shape of an object, even when it is viewed from different angles or distances. It allows us to identify and understand objects based on their familiar shapes, regardless of the variations in how they appear due to changes in viewing conditions. Shape constancy helps us perceive objects as having a consistent shape, providing stability and continuity in our visual perception. The perceptual constancy that the brain recognizes, despite the angle, distance, or illumination of how the object is viewed, is size constancy. Size constancy refers to the ability to perceive the true size of an object regardless of its distance from the observer or the viewing angle. Our brain compensates for changes in distance and angle to maintain a consistent perception of the object's size. This allows us to accurately perceive the size of objects even when they appear smaller or larger due to their distance or perspective.
