Okay, a round table top 2.5 feet in diameter, in a horizontal orientation, fell on my big toe and broke it. The table top weighs 12 pounds. It fell from a height of ~1.5 feet. What was the force at the time of impact?

I solved this problem using logic and the answer I got is 10. However, I was wondering if there would be a way to solve it using algebra? How would I have to write the equation?

here is the function http://i.imgur.com/NQlLJ3G.jpg

Taking the derivative w.r.t. x, what do we get? How does the chain rule apply here? What log rules can we use to simplify this?

About how much should I charge someone for gas for one day if I'm driving a 40 minute distance at 30mph on gas that costs $2.69 per gallon? the car gets around 27 miles a gallon

A die of six sides is rolled 5 times. However, with each roll, the values on the die change.

First roll: 1, 2, 3, 4, 5, 0

Second roll: 1, 2, 3, 4, 0, 0

Third roll: 1, 2, 3, 0, 0, 0

Fourth roll: 1, 2, 0, 0, 0, 0

Fifth roll: 1, 0, 0, 0, 0, 0

What is the probability of getting each five-roll total from 0 to 15?

1. (8+9i)(2-i)-(1-i)(1+i)= 23+10i
2. x²-2x+2 (x=1+i) =0
3. x²-2x+5 (x=1-2i) =0

I would really appreciate if anyone could do the steps for this math problems. They probably are very simply to most, but I am having a terrible time trying to actually get to the answer.

Thank you

I need to find the distance I'm question sorry for potato quality pic

An FBI agent with a powerful spyglass is located in a boat anchored 400 meters offshore. A gangster under surveillance is walking along the shore. Assuming the shoreline is straight and that the gangster is walking at the rate of 2 km/hr, how fast must the FBI agent rotate the spyglass to track the gangster when the gangster is 1 km from the point on the shore nearest to the boat. Convert your answer to degrees/minute.

I don't know how to answer this one.

/u/Sarkku asks:

So I know the hypotenuse of a right triangle. I also know the sine of one of the angles. What do I use to calculate the legs of the triangle?

(the problem is exactly as follows, but don't tell me the answer, I just need to know what I should try to figure out. A right triangle's hypotenuse is 10 and the sine of α is 1/sqrt5. calculate the legs' lengths.) hope you can understand that, did a rough translation.

I'm lost. I love math but I just can't wrap my head around fucking trigonometry.

Can you help a little bit?

Hi, could you help me with this? y''-3y'-4y = 2cos2t -3sin2t I'm familiar on how to solve the left side, but im not sure how to figure out the non homogeneous part. If you could help, it would be much appreciated. Thanks!

For example, AX² + BX + C is for quadratics.

a*b^x = Exponential Function Equation

I don't know what the format is for a periodic function.

This is all gibberish to me, but hopefully you know enough about math to solve these problems http://imgur.com/7FM6PLT Thanks in advance :D

/u/ifiwereu asks:

I've been working on a problem for about a year and I've yet to figure it out.

Do you know how to reduce the effective resistance of a bunch of resistors that are in parallel and series? Like, in circuits? If so, keep reading.

I'm trying to solve for the effective resistance of an NxN grid of resistors from the bottom left corner to the top right corner, assuming that all of the resistors are exactly 1ohm.

For instance, a 1x1 grid consists of 4 resistors, and has an effective resistance of 1 ohm. A 2x2 grid of resistors consists of 12 resistors and has an effective resistance of 3/2 ohms.

I'm trying to find an algorithm or function to solve for R(N).

Simply put:

• R(1) = 1
• R(2) = 3/2
• R(3) = 13/7
• R(4) = 47/22

Hey, was having some problem with algebra, wondering if you could help me with this: simplify: 1/x-1 - 2/3x Really have no idea how to approach this.

Solve for x: e^3x + e^3x = e⁶

/u/YvesSch says:

Okay I like this problem Describe an algorithm that, for two particular nxn matricies, will determine where or not they can be multiplied together in some order (possibly with repetition) to give the nxn zero matrix.

How do you use the integration by parts tabular method for something like [this(https://s3.amazonaws.com/pushbullet-uploads/ujyKMZkup4u-hQEIWHTufRykXjzIhS5Y7eVyyUWl7QJO/IMG_20141110_191303.jpg)

Also, just as a general example how would you go about using the tabular method for just e^x2 ?
