solve: 5log (subscript 10^x) + log (subscript 10^5) = 1 + 2log (subscript 10^4)

factorise: a - 2ab - 2bc + c

value of t so that: 9x^2 + 16x + t is a perfect square

I have a basic question on calculus ....please can someone explain to me :


Let f(x) = x^2

y + delta y = f ( x + delta x )

The book says that a small increase in x will cause a small increase in y.

But if I put lets say 3 and 2 for x and dx y is 5^2 which is 25.

But this isn't the same as f(3) + f(2) which equals 13 ?

What have I done wrong ?




Also, can f ( a+b+c ) be treated as f(a) + f(b) + f(c) ?


Thanks a lot for any help

1).u can write a^(n)-b^(n)=c^(2)-d^(2)
here a,b,c&d are natural & real numbers.n is a natural number.
like 7^(3)-4^(3)=48^(2)-45^(2)
2).u can also write for any number say x having any power say
n can also be written as
x^(n)=y^(2)-z^(2)
here x ,y & z are natural & real numbers
like 3^(3)=14^(2)-13^(2)
from this show that it is impossible to write
a^(n)-b^(n)=x^(n) for n>=2.

If my car gets 25 miles per gallon. And gas is $3.00 per gallon. And I travel 3 miles, how much have I spent?

Can you write out the equation/formula. This isn't homework, I'm just not good with math and want to know.

Thanks

Okay, just a wierd question, when making a website you can make it divide the screen up into 2 "frames" each showing a different website, but what if you make the second website show the main website in a frame of it's own? The first website should still show the second... wierd, maybe it's like putting a video camera to a T.V. that is showing the display... fun ^_^

I tries putting a folder in a folder that it contained once on my computer, that didn't work though...

Let P=(3,2,-1) and Q=(-2,1,c) and R=(c,1,0) be points in R3 (3 spaces). For what values of c is PQR a right triangle?

I got 34/8 for one value of c, but I'm not sure if I'm right or not. Can anyone help?
