BF2S Forums Geometry Help!!!! Please!!!!

d) 2/3 times x minus 17/6 = 5/2
so x(2/3)= 5/2 +(17/6)
x(2/3) =(15/6)+(17/6)
x(2/3)= 5 and 1/3
x= 5 and 1/3 divided by 2/3
x= 8

I forgot to change my minus earlier

the answer is 8

To calculate your triangles, you need to know about Pythagore's triangle. Do you know this?

No, look closely, I "x" the "6" on the other side.
I am completely confused.

Zimmer, if you're gonna multiply, you need to multiply on both sides of the equation. in yours, you only multiplied on the right side (the 5/2) but not the left(the 2/3)

Shit, I fail at maths. Hmmmmmmmmmmmmmm. I went wrong somewhere. Wait....I went wrong everywhere.

Why did you get suspended naughty little boy?

hahaha, this little freshman was fucking with my brother and calling him names and threatining to beat him up. So I just beat him up a little (He had to go to the hospitol and get 15 stiches next to his eye and he got a broken jaw) You know nothing major!!!

How did you get that?
2/3x - 17 = 5/2 x 6
2/3x - 17 = 15
2/3x = 32
2x = 96
x = 48

Look at mine.

so is it 8 or 48?

Try using parantheses

2/3x -17/6 = 5/2
so
4/6x - 17/6 = 15/6
so
4/6x = 15/6 + 17/6
so
4/6x = 32/6
(6/4)(4/6)x = (32/6)(6/4)
**** (6/4)(4/6) cancels out and the 6s cancel out here (32/6)(6/4)****
so
x= 32/4
so
x=8


plug 8 into the calculator to check
((2/3)(x)) - 17/6 = 2.5 (or 5/2)

check
done

by the way this is a cake walk. i'll set you up, but i won't finish them. you've heard of SOHCAHTOA right?
you may need to study a bit if you're running into trouble with this stuff.

D) first of all, add the 17/6 to 5/2 on the right side. divide by 2/3 to solve for x. this problem had nothing to do with trig.

G) sin 57 = 239/x

H) tan y = 36.8/22

2. draw a triangle. tan32.8 = x/40.

3. same triangle as (2). sin64 = x/65

eh heggs has set you up right here. These are all right. Complete these and you're golden.

so do i just put that into the calculator to get the answers? I can find a calculator online

Trig = easy shit. I took my differential equations final yesterday. You guys wanna try problems like:

Given the matrix
      -2  1  -1
A = 1  -3  0
      3  -5  0

i) find the eigenvalues
ii) for each eigenvalue find the algebraic and geometric multiplicities
iii) for each eigenvalue [lambda] find the smalles integer k such that the dimension of the nullspace of (A - [lambda]I)^k is equal to the algebraic multiplicty
iv) for each eigenvalue find q linearly independent generalized eigenvectors, where q is the algebraic multiplicity
v) verify that the collection of the generalized eigenvectors you find in part iv for all of the eigenvalues is linearly independent
vi) find a fundamental set of solutions for the system y' = Ay

Or how about...

given

y'' + 3y' + 2y = 3e^(-4t) , y(0) = 1, y'(0) = 0

find the homogenous equation, and then find the particular solution. Use these to find the general solution. Then find the solution satisfying the particular given initial conditions.

Cheers

Haha I know I'm just messing with ya! Do you still need to find out how to set up those problems? I could start typing them up in word or something.

Ok, I am going by what you gave me. Anybody else argue with these answers?

60.4 is right> how do you put a degrees symbol?

yeah, all of those problems can be solved with a scientific calculator, just so you know. If you don't have one get one.

Hehe BBCode superscript. I just put the letter O in superscript.
