There are 4 quadrants in a grid and 8 octents. I assume that octents 1 and 2 are in quadrent 1, splitting it in half at 45 degrees. Is this correct?

Yep, I successfully defended my thesis for a PhD in statistics today, so you can call me Dr. now!

And so this isn't chatting, what is your stance on frequentist versus Bayesian statsitcs? Which side's got it right?

f(x) = (x^2)(e^x)
I was able to get it down to (x^2)(e^x)+(e^x)(2x) but then I'm not sure what to do. Do I just plug in numbers until I can get it to negative? In which case it would be x < -1, without going into crazy decimals?

Thanks for any help.

I have several math problems that have been troubling me. I have answers for some but Im 100% sure that they are wrong. I've tried tutors but they had trouble with them and their answers were so complex I dont trust them. Any help would be appriciated. ^ = Exponent.

1) Factor y^2 + 8y + 16 - 169t^2

2) Multiply (x^2 + x - 1)(-x^3 + x^2 + 1)

3) The product of the reciprocals of two consecutive integers is 1/90. Find the integers.

4) __6__ - __2__
x^3 - 125 - x^2 - 25

5) One summer, Oscar mowed 4 lawns for every 5 lawns mowed by Luis. Together they mowed 144 lawns. How many did each mow?

6)David can paint a bedroom in 1.75 hr. Jay can paint the same room in 2.5 hr. How long will it take them, working together, to paint the bedroom?

7) Solve 9x^2 + 3x = 0

8) Solve 3x^3 + 4x = -8x^2

9)Left f(x) = 3x2 - 21x + 286. Find a such that f(a) = 286.

10) Find the domain of the function f given by f(x) =
__8-x__
x^2 + 6

If I (n) = Integral (limits pi/2 and 0) e^2x * Sin^n (x) dx

how do i show 2*I (n) = e^pi - n* Intergal (same limits) e^2x * Sin^(n-1) (x) cos (x) dx

Hence, prove

(4+n^2) I (n) = 2e^pi + n(n-1) * Intergrel(version n-2)

I can't quite get there although I have come close. Should I use reduction forumla method first or should i follow the intergration by parts first?

Any help will be appreciated!
