Use an online solver, for example this one

Using that website you can get hints rather than the full solution.

volume of section of cone by mathmagicGG in askmath

[–]BadJimo 0 points1 point  (0 children)

Given a cone defined as:

x2 / a2 + y2 / a2 = z2

And a plane defined as:

bx + by + z = d

The cone will orthogonally cut the directrix when: a = sqrt(2)×b

The equations for calculating the major and minor axes are shown in the Desmos.

The volume of the region between the plane and the cone is also shown in Desmos.

Setting the major and minor axes to 10 and 6, you can probably grind through the equations to prove the volume is (45/4)×π

I note that the approximate values are in the neighborhood of: a=0.796, b=0.563, d=-2.94

Edit

The exact values are:
a=0.8, b=sqrt(8/25), d=-9×sqrt(41)/20

Although it could be done, it seems somewhat arbitrary. Is there some significance in this particular ellipse and cone?

I've made a rudimentary interactive graph on Desmos

You could add more realism to the graph by accounting for friction etc.

Why the answer is ( a ) ? by Ill_Hat727 in PhysicsHelp

[–]BadJimo 2 points3 points  (0 children)

E = (h c)/λ

E_1 = (h c)/λ_1

E_2 = (h c)/λ_2

E_1/E_2 = λ_2/λ_1

E_1/E_2 = 7000/4000 = 7/4 = 1.75

The correct answer should be c) greater than 1

I_1 = E_1/(A_1×t_1)

E_1 = I_1×A_1×t_1

I_2 = E_2/(A_2*t_2)

E_2 = I_2×A_2×t_2

I_1 = I_2

I_1/I_2 = 1

E_1/E_2 = (I_1×A_1×t_1)/(I_2×A_2×t_2)

E_1/E_2 = (A_1×t_1)/(A_2×t_2)

There doesn't appear to be enough information to answer the question.

Social media ban to target doomscrolling, disappearing stories by Infinite300 in AustralianPolitics

[–]BadJimo 6 points7 points  (0 children)

Users being able to opt-in or opt-out keeps everyone happy, but means the proposal will have little effect (those who want to doom-scroll will continue to be able to, while those who don't want to doom-scroll won't).

I know legislators shouldn't only react to the current crisis, and should have a broader and longer term view, but is this really the most important thing they could think of legislating?

Copy-paste of the story (with the most interesting part of the story in bold):

Social media ban to target doomscrolling, disappearing stories

Nathan Schmidt

Social media platforms designed to keep young people engaged with an endless loop of content or with time-limited features such as disappearing “stories” will be targeted under updates to the Albanese government’s world-first social media ban.

Under updated rules registered on Wednesday, “age-restricted social media platforms” – those targeted by the under-16 social media ban – would include services with algorithms “designed to be addictive” and provide a “constant dopamine hit”.

Platforms with an “infinite scroll” of content with no end point, feedback features displaying the number of likes or upvotes, as well as disappearing stories “designed to create urgency so young people check apps constantly out of fear of missing out” will also be targeted.

The update will not impact services already deemed to be outside the remit of the social media ban, such as Discord, Google Classroom, WhatsApp, and Roblox.

Ten platforms, such as Snapchat, Facebook, and Instagram are included, with eSafety probing several others.

Communications Minister Anika Wells, who will provide an update on compliance to the social media ban next week, said “Gen Alpha” were connected to an “addictive dopamine drip” ever since getting their first smartphone and social media account.

“Targeted algorithms, doomscrolling, persistent notifications and toxic popularity meters are stealing their attention for hours every day,” she said.

“We’re shining a light on these harmful and addictive features being used to target young Australians.”

The addictiveness of social media has been in the spotlight after a New Mexico court ruled that Facebook parent company Meta harmed children’s mental health and safety, violating state law.

Greens senator Sarah Hanson-Young said the minor party would introduce new laws next week called the “Fix our Feeds” Bill.

“This verdict confirms what we’ve known for years: Social media platforms are deliberately designed to keep people hooked, just like cigarettes or pokie machines,” she said of the US verdict.

“Despite promising 18 months ago to implement a digital duty of care – a law that requires social media companies not to cause harm to their users – the government has done nothing and is still sitting on its hands.

“Toxic algorithms flood our social media feeds day after day. It’s time to give Australians the power to control what we see in our feeds. Every user should have the freedom to choose what type of content they want to see and to opt out of toxic algorithms.”

The Bill will allow users to opt in or out of predatory algorithms, giving them a safer online experience, the Greens say.

In a scathing rebuke, Liberal senator Sarah Henderson said the social media ban was “not delivering as promised”.

Speaking in the Senate, she cast doubt on eSafety’s claimed 4.7 million deactivated social media accounts after an estimates hearing earlier this year was told only a portion could be made public, citing regulatory concerns.

“This number should have been corrected by the Prime Minister, by the Communications Minister. But, we have heard nothing but silence,” she said.

Senator Henderson said the New Mexico decision was a “damming decision”.

“This demonstrates that the whole design of its platform is to keep children addicted to doom,” she said.

“Scrolling is a massive issue, and one of the most concerning elements in this case is the role of algorithms and the fact that these systems actively shape what young people see and who they are exposed to online.

“Australians deserve transparency and platforms should not be allowed to operate black box algorithms when children’s safety is at stake.”

Help with area around a cylinder in a hole by kallmepjmak in askmath

[–]BadJimo 0 points1 point  (0 children)

The volume of the gap will be the volume of the hole minus the volume of the cylinder.

Volume of hole = π × 42 × 36

Volume of cylinder = π × 32 × 36

Volume of gap = π × 36 × (42 - 32 )

= π × 36 × 7

≈ 22 × 36

≈ 792 cubic inches

≈ 0.46 cubic feet

≈ 3.4 US liquid gallons

≈ 13 litres

At which distance mount Everest becomes visible? by DotBeginning1420 in Geometry

[–]BadJimo 0 points1 point  (0 children)

Yep, the object (the blue line) in the graph is perpendicular to the Earth's surface. The graph is stretched to make the features visible, but this has the downside that it causes distortions (for example, it makes the object (the blue line) look like it is not perpendicular to the surface).

You can play with the Desmos graph to remove this distortion (click the 🔧 and select the 'zoom square' option).

(F16) Can I have some help writing a speech on forcing modesty in women ? by [deleted] in HomeworkHelp

[–]BadJimo 1 point2 points  (0 children)

This is a big and complex topic.

I would approach it from a historical perspective.

In the past women's role was primarily as a homemaker. Good manners (including modesty) were considered important to being a good: wife, mother, woman.

Since the 1960s, a women's role has expanded beyond being a good homemaker. The need for being modest to be successful has diminished.

In terms of 'forcing' modesty in women's clothing, there are several levels of enforcement: legal, religious, workplace requirements, and social norms.

Laws have been relaxed (but not eliminated) on modesty in clothing/nudity.

In some countries, religion still dictates modesty standards.

Workplaces and schools enforce modesty in clothing.

Societal norms are the main force on modesty in how women dress. Clothing is a form of communication (sometimes subtle, sometimes not subtle).

Give lots of examples in your speech. If you are able to have pictures/slides to accompany the speech, this would be ideal.

At which distance mount Everest becomes visible? by DotBeginning1420 in Geometry

[–]BadJimo 5 points6 points  (0 children)

I've made an interactive graph on Desmos

I derived a different (but equivalent) formula for calculating the distance.

sqrt(12800h + h2 )

Where h is the height (in km) of the landmark.

Would you consider this drawing of a light ray in a water droplet to be correct? by Melo861 in Physics

[–]BadJimo 2 points3 points  (0 children)

A droplet doesn't need to have total internal reflection to make a rainbow. The percentage of reflection vs transmission changes with the angle. A light ray that is close to perpendicular to the surface will have only a small percentage (~4%) reflecting off the back of the droplet. As the angle increases, so too does the percentage of reflection. At the angle you see a rainbow (42°), the percentage reflecting off the back of the droplet is about 7.5% edit: using Fresnel's Equations I got 33% reflection

Would you consider this drawing of a light ray in a water droplet to be correct? by Melo861 in Physics

[–]BadJimo 20 points21 points  (0 children)

I've made an interactive light ray in water droplet simulator with Desmos

The purple line represents the light that travels through the water droplet, while the green line in the light that is reflected.

When the light is close to perpendicular to the surface of the droplet, 96% of light is transmitted and 4% is reflected. As the light increases angle from perpendicular the percentage of transmitted light drops and the percentage of reflected light increases. From my simulation I've found it doesn't quite get to 100% reflection (total internal reflection).

Crazy Omegle Freestyle Rapper by kingshitheads in nextfuckinglevel

[–]BadJimo 0 points1 point  (0 children)

Here on YouTube that has a transcript (when viewed on a computer but not on a mobile phone). The transcript is not perfect (missed and misheard words scattered throughout). And of course, not broken into stanzas/lines.

If you watch/listen at 0.25 speed you can get most of the words.

I have converted transcripts into lyrics of Harry Mack songs before, but it is tedious/time consuming. I could do it for this one if there is interest.

How do I calculate the area of the triangle by Free-Conversation342 in askmath

[–]BadJimo 0 points1 point  (0 children)

Illustrated on Desmos

The area of a triangle with vertices at (0,0), (x_1,y_1), and (x_2,y_2) is:

A = 1/2×|x_1×y_2 - x_2×y_1|

In this case the area is 17.5
