A winch at the top of a 12 meter building pulls a pipe of the same
length to a vertical position. the winch pulls in rope at a rate of -
.2 meter per second. Find the rate of vertical change and the rate
of horizontal change at the end of the pipe when y=6.

[Difficulty]
can't get the amswer the book says.

[Thoughts]
S^2=y^2+X^2
2S(ds/dt)=2y(dy/dt)+0
2S(-.2)/2y= dy/dt
2/5= dy/dt
but the Answer is 1/4 and -.1154700

IQ tests are used to determine your mental age and express this as a value proportionate to your actual age; resulting in an expression known as an Intelligence Quotient [IQ]

I am 18; my IQ is 136. [I am assuming you understand principles of algebra]:

IQ = mental age ÷ physical age x 100
136 ÷ 100 = mental age ÷ 18
1.36 = mental age ÷ 18
1.36 x 18 = mental age
24.48 = mental age

Mentally I am 24.48 years old

Use this formula to work out your mental age. What is your mental age AND real age?

how do you find the critical points of an equation if it has both x and y variables. For instance.

f(x,y) = 3x - (x^3) - 2(y^2)+(y^4)

I just don't know how to get the critical points because when you take the derivative and split it up into x and y components, there is no way to get the value of the other component.

What are the various confidence intervals for 2 Standard Errors v. 2 Standard Deviations from a Linear Regression Trendline or Simple Moving Average?

For instance, if I determine the value that is Two Standard Errors from a 50-day Linear Regression Trendline and I determine the value that is Two Standard Deviations from that same 50-day Linear Regression Trendline, they can't both have a Confidence Interval of 95% if they are dramatically different values; can they? By way of example, in most stock trading software, Standard Error Bands are used most often in combination with a Linear Regression Trendline and Standard Deviation Bands are used most often in conjunction with a Simple Moving Average. Can someone explain why this might be and what the different confidence intervals represent?
