Hey /sci/, I could use some help. Im failing calculus right now, and have a quiz tomorrow that could save my life, but have no idea what im doing. I have some practice problems and would really appreciate some help. Here we go, Water flows into a tank at a rate of dW/dt=(1/75)(600+20t+t^2) where dW/dt is measured in gallons per hour and t is measured in hours. if there are 150 gallons of water in the tank at t=0, how many gallons are there at t=24 I have to solve each problem twice, using each method once. first one would be the antiderivative method of plugging in/ solving for a constant and the second is something with f(b)-f(a) pic related, mfw i look at this problem

>Join mensa >First meeting >First thing I hear is some girl saying "My father got me into cambridge I wont be going to the smelly universitys with all the nomies" >Amazed at how arrogant and pretentious she is yet remain optimistic about other members >20 Minutes later >See 2 guys arguing >One of them stands up and says "Listen 133 when my divine wisdom, glory and prestige rubs off onto you, you must know as it transcends into your deviation that was a damn blessing that I would honor you, so humble yourself 133, humble yourself. I am not even making this shit up however the last part is only very slightly paraphrased. Why are mensa members so arrogant?

>TI-83 question I see the solution for the equation (4.50)(7.30)cos(320º – 85.0º) = – 18.8 When i use my calculator and i plug in the numbers i get (4.50)(7.30)cos(320º – 85.0º) = -26.8 Whats going on? Do i have to change something on the calculator or am i not plugging in the numbers properly?

Ok here is a odd one, say i like to have sex with pregnant women, but hate kids, could i use hormones or something to simulate pregnancy, with all the lactating and weight gain my messed up head likes?

Hello Mathpeople! I was recently assigned this problem and have no idea where to begin or what this even means. The professor briefly went over how to use these techniques to solve the tower of hanoi but he spent most of the class playing with a little web application. Suffice to say I have no idea what I am doing. Any help would be greatly appreciated! Thanks. Solve the recurrence y_{n+1} = 2y_n + n for non-negative integer n and initial condition y_0 = 1 using a) Ordinary generating series b) Exponential generating series c) Telescoping d) Lucky guess + mathematical induction e) Any other method of your choice Include the supporting calculations used to arrive at your solutions.

How do you manage your notes? I have notes on school, work, all of my hobbies, to-do lists, etc etc. I used to have them in one big .doc file, but now I have them in separate .txt files, but it still sucks. How do you do it - if you keep any notes at all?

How does an antimatter propulsion rocket work? My idea is a chamber where antimatter is mixed with matter, some sort of gas. The energy produced heats whatever gas is used to extremely high temperatures and expands rapidly. The pressure is relieved by shooting the plasma out the thruster producing force. Is this how most antimatter thrusters work or is there some other design? Are other designs more fuel effecient?

Okay, I'm coming here to you smart motherfuckers because I lack your intelligence. I'm currently watching the Joe Rogan podcast where he has his guest as Neil Degrasse Tyson. Neil said that if he were to ever meet an alien outside of Earth's atmosphere, (like a space-walk) or something, he'd flip them a coin so that if they caught it, he'd know if they're made out of anti-matter and know if they're safe to shake hands with or what-have-you. My question is this: Let's say the aliens were made out of anti-matter, what would happen when they catch the coin? Would that created a black-hole and goodbye Earth? I'm genuinely curious. Pic semi-related.

What does /sci/ think about companies like Deep Space Industries and Planetary Resources Inc. looking into mining asteroids? Does this seem realistic to you?

Silly question, but how do I place data cursors at a designated point on a matlab plot? I know there is a data cursor button but it won't let you put the cursor at the exact spot you want. I'm trying to find and label an x-value given a certain y-value.

Not really sure what I'm doing wrong on this problem. If y' = xy, then y''' = ____ a) xy b) xy(x^2+1) c) xy(x^2+3) d) xy(x^2+5) e) xy(x^2+7) I keep getting xy(x^2+2) which is not one of the choices. I got y'' = (x^2)y + y Anyone care to help? I'm not good at implicit differentiation. Pic unrelated, first image on google for implicit differentiation

I put my liquor outside and now I need to know if it'll freeze or not. It's 500 ml of 10% ethanol and was about 12 Celcius when I put it outside. Current outside temperature is -5 Celcius.
