My fellow math brodas, help

A. Depending on which variable you choose to integrate with, you can capture the total bounded region with either -2 ≤ x ≤ (-1 + √5)/2 or 1 ≤ y ≤ (5 + √5)/2, where the upper endpoints correspond to the coordinates of the appropriate intersections:

y = x² + 1

⇒   x = (x² - 2)² - 2

⇒   x⁴ - 4x² - x + 2 = 0

⇒   (x - 2) (x + 1) (x² + x - 1) = 0

⇒   x = 2, x = -1, x = -1/2 ± √5/2

⇒   y = 5, y = 2, y = (5 ± √5)/2

On the other hand, we can compute the areas of A and B separately, then sum those integrals. Area A is easier to compute by integrating with respect to y over 2 ≤ y ≤ (5 + √5)/2, while area B is easier to find by integrating x over -1 ≤ x ≤ (-1 + √5)/2.

B. I'll stick to the split-region approach.

First, we find equations for the appropriates halves of either parabola:

• y = x² + 1   ⇒   x = ± √(y - 1)

and x = -√(y - 1) describes the left half of the blue parabola;

• x = (y - 3)² - 2   ⇒   y = 3 ± √(x + 2)

and y = 3 - √(x + 2) describe the bottom half of the red parabola.

Now we can set up the integrals.

Area of A:

\displaystyle \int_2^{(5+\sqrt5)/2} \left(\left(-\sqrt{y-1}\right) - \left((y-3)^2-2\right)\right) \, dy \\ ~~~~~~~~ = -\int_2^{(5+\sqrt5)/2} \left((y-3)^2 - 2 + \sqrt{y-1}\right) \, dy

Area of B:

\displaystyle \int_{-1}^{(-1+\sqrt5)/2} \left(\left(3-\sqrt{x+2}\right) - \left(x^2+1\right) \right) \, dx \\ ~~~~~~~~ = - \int_{-1}^{(-1+\sqrt5)/2} \left(x^2 - 2 + \sqrt{x+2}\right) \, dx

Alternatively, one can prove that the regions A and B are symmetric across the line y = x + 3, so we can simply pick one of these integrals and double it.

C. Computing the integrals, we find

area of A = 2/3

area of B = 2/3

and so the total area is 2/3 + 2/3 = 4/3.

Which word, if it occurred in a true/false question, would give you a hint at the correct answer?
Anton [14]
Hey there

<span>The first step is to carefully read every single word of the question and answers,keeping in mind that the some small detail can affect the answer.

You should also pay great attention to negative words and prefixes. Words such as "un" can make your answer wrong if unread properly. If an event is "unlikely to happen," that means it is most likely an occurrence.</span>

mars1129 [50]

Answer:

"I can't concentrate—it's really hard to focus on  school work!" --------------->

I will find a way to concentrate on school work

"I am too disorganized and I never have enough time." "Some subjects are really hard for me to learn." ---------------->

I will make out time to learn these subjects that give me a tough time

"I get  discouraged and stressed out." "I'm bad at taking tests." ---------------->

This may take some time, but I'm sure I'll ace those tests with proper practice

Explanation:

A growth mindset is a belief that intelligence can be developed and negative circumstances can be overcome.

Instead of using negative and defeatist statements, growth mindset emphasizes on never giving up, trying multiple ways to succeed and staying positive

What is the central idea of the article Elephants Attack as Humans Turn Up the Pressure?
docker41 [41]

Answer: c) Researchers think that stresses created by humans are the reason behind increasing numbers of elephant attacks.

Explanation:

The aforementioned article by National Geographic shows that the higher number of elephant attacks on humans are as a result of human activities that are placing stress on elephants.

Humans are increasing in population and as a result need more land for farming. This is resulting in a shrinking habitat for elephants who then encroach on human farms and are killed for it which leads to some elephants having Post Traumatic Stress Disorder and killing other humans which then continues the cycle.
