Why did helga the witch sign up for anger management classes

Answers

Helga enrolled in anger management classes to control her temper, realizing it affected others and herself negatively, hoping to improve her witchcraft and life.

Helga the witch signed up for anger management classes because her temper was causing issues not just for others, but also for herself. Constantly flying off the handle and hexing everything in sight led to her feeling isolated and out of control. Plus, her cottage was starting to look like a scene from a horror movie, with all the shattered potion bottles and singed curtains. She realized that mastering her emotions would not only make her a better witch but also improve her quality of life. So, begrudgingly, she enrolled in the classes, hoping to learn some magical techniques for keeping her cool.

Sales fall from 300 per week to 270 per week what’s the percentage change

Answers

Hi there! 

Your question: 

Sales fall from 300 per week to 270 per week what's the percentage change?

My answer:

The formula for calculating percent change is as follows: 

[(y2 - y1)/y1]*100=your percent change 

y2= first value 
y1=second value 

Plug the numbers in: 

[(300-270)/300]*100

[30/300]*100

0.1*100

10 

Therefore, the percent change is 10%

Hope this helps! Let me know if it's incorrect so I can fix it:)

What is the difference between advanced calculus and real analysis?

Answers

The content of any course depends on where you take it--- even two courses with the title "real analysis" at different schools can cover different material (or the same material, but at different levels of depth).

But yeah, generally speaking, "real analysis" and "advanced calculus" are synonyms. Schools never offer courses with *both* names, and whichever one they do offer, it is probably a class that covers the subject matter of calculus, but in a way that emphasizes the logical structure of the material (in particular, precise definitions and proofs) over just doing calculation.

My impression is that "advanced calculus" is an "older" name for this topic, and that "real analysis" is a somewhat "newer" name for the same topic. At least, most textbooks currently written in this area seem to have titles with "real analysis" in them, and titles including the phrase "advanced calculus" are less common. (There are a number of popular books with "advanced calculus" in the title, but all of the ones I've seen or used are reprints/updates of books originally written decades ago.)

There have been similar shifts in other course names. What is mostly called "complex analysis" now in course titles and textbooks, used to be called "function theory" (sometimes "analytic function theory" or "complex function theory"), or "complex variables". You still see some courses and textbooks with "variables" in the title, but like "advanced calculus", it seems to be on the way out, and not on the way in. The trend seems to be toward "complex analysis."  hope it helps

Final answer:

Advanced calculus covers computational aspects and applications of calculus in multiple dimensions, while real analysis focuses on the theoretical fundamentals, such as rigorous development of the real number system and proof-based examination of limits and continuity.

Explanation:

The difference between advanced calculus and real analysis lies in the focus and depth of the subjects. Advanced calculus, also known as calculus III in some curricula, typically extends the study of calculus to multiple dimensions, covering topics such as partial derivatives, multiple integrals, and vector calculus. It focuses more on the computational aspects and applications of calculus.

Real analysis, on the other hand, delves deeper into the theoretical underpinnings of calculus and analysis. It deals with the rigorous development of the real number system, sequences and series, continuity, differentiation, integration, and convergence. Real analysis puts a strong emphasis on proof and logical reasoning, providing a foundation for the truth and logic behind the mathematics used in calculus.

While both subjects are mathematically advanced, real analysis is considered to be more abstract and is often a stepping stone for further study in pure mathematics. Familiarity with calculus is often a prerequisite before studying real analysis as it lays the groundwork for the more complex theoretical concepts.

What is the perimeter of the rectangle shown on the coordinate plane, to the nearest tenth of a unit?

15.3 units
20.4 units
30.6 units
52.0 units

Answers

To calculate the perimeter, consider each side separately. Since this is a rectangle, you have 2 pairs of sides of equal length, so you just have to calculate the length of one of each pair of sides and then double each and add them to find the perimeter.

Top side: If you look carefully, this side is really the hypotenuse of a triangle that is 2 units tall and 10 units long. Using the Pythagorean Theorem, you can calculate the length of the hypotenuse to be 2^2 + 10^2 = c^2 --> c = 10.2

Left side: Just like the top side, this side is the hypotenuse of a triangle that is 5 units tall and 1 unit long. Pythagoras again: 5^2 + 1^2 = c^2 --> c = 5.1

Since you have two of each side that are the same length, double each and add for the final perimeter: 10.2*2 + 5.1*2 = 30.6
firstly, we will name the points as the following:
(-6,4)  will be named as A
(4,2) will be named as B
(3,-3) will be named as C 
(-7,-1) will be named as D 
then we will use the distance formula between any 2 points on the graph which equals=[tex] \sqrt({x}1-{x}2)^2 +({y}1-{y}2)^2[/tex]
So,
AB=[tex] \sqrt[/tex](-6-4)^2+(4-2)^2 =2[tex] \sqrt[/tex]26
BC=[tex] \sqrt[/tex](4-3)^2+(2+3)^2 = [tex] \sqrt[/tex]26

AD=[tex] \sqrt[/tex](-6+7)^2+(4+1)^2 =[tex] \sqrt[/tex]26

A rancher needs to enclose two adjacent rectangular​ corrals, one for cattle and one for sheep. if the river forms one side of the corrals and 180 yd of fencing is​ available, find the largest total area that can be enclosed.

Answers

Refer to the diagram shown below.

x = the width of each rectangular fence
y = the length of each rectangular fence

The amount of fencing available is 180 yards, therefore
2x + 2y = 180
x + y = 90               (1)

The total fenced area is
A = 2xy                 (2)

From (1), obtain
y = 90 -x               (3)
Substitute (3) into (2).
A = 2x(90 - x) = 180x - 2x²

To maximize A,
A'(x) = 180 - 4x = 0   => x = 180/4 = 45 yds
y = 90 -x = 45 yds

The largest total enclosed area is
A = 2*x*y = 2*45² = 4050 yd²

Answer: 4050 yd²

A polynomial function P(x) has a degree n. If n is even is the number of turning points of the graph of p(x) even or odd? What can you say about the number of turning points if n is odd?

Answers

I think the number of turning points if n is even  is odd.
For n = odd it could be odd or even.

The number of turning points if n is odd if A polynomial function P(x) has a degree n, is even.

What is polynomial?

A polynomial is a mathematical expression that solely uses the operations of addition, subtraction, multiplication, and positive-integer powers of variables. It is made up of indeterminate (also known as variables) and coefficients.

Given:

A polynomial function P(x) has a degree n,

A turning point is when the derivative's sign changes. A relative maximum or relative minimum might mark a turning point (also known as local minimum and maximum). A turning point is a stationary point if the function is differentiable, however not all stationary points are turning points.

For example, if the degree is 2 then the number of turning points will be 1

The general formula is, the number of turning points = n - 1

Thus, for odd n, the turning point will be even.

y = -16x² + 32x + 3

Write the equation in the standard form for a parabola.
y = -16[x² - 2x] + 3
   = -16[(x-1)² - 1] + 3
   = -16(x-1)² + 16 + 3
y = -16(x-1)² + 19

Find two numbers whose sum is 49 and whose product is 544

Answers

17 and 32
I know this because,
17+32=49
And,
17×32=544

The two numbers are 16 and 33. They satisfy the conditions that their sum is 49 and their product is 544, as verified by setting up and solving a system of equations.

To find two numbers whose sum is 49 and whose product is 544, we can set up a system of equations based on the information given. Let's call the two numbers x and y. So, we have two equations:

x + y = 49xy = 544

By solving these equations simultaneously, we can find the values of x and y.

The easiest way to solve this might be to express y in terms of x from the first equation: y = 49 - x. Then, substitute this into the second equation:

x(49 - x) = 544

This simplifies to a quadratic equation:

x^2 - 49x + 544 = 0

Factoring this quadratic equation, we get:

(x - 16)(x - 33) = 0

Which gives us two possible values for x:

x = 16x = 33

Plugging these back into the equation for y, we get:

y = 49 - 16 = 33y = 49 - 33 = 16

So the two numbers are 16 and 33.

y = (-6)x + (-3)
