(2N)3 x (N3+1) - (2N2)3

the 3's are little ones, cubed and the last 2 in the end is squared!



also

2 radians nearest degree?

4=10k solve for K

 

[skaman607]

2 radians is 360 degrees k=2/5 I'll take a look at the other one later

 

[KAYNE]

THE ANSWER IS "C"

4=10k solve for K

man, the basic algebra ones are too simple;
you need to understand the basics, or fail the class

I don't think the radian answer above is correct; there are 2 * pi radians in a circle.

4=10k solve for K

1.

8N^3 x N^3 +1 - 8N^6

-8N^6 + 9N^3 + 1

-1N^3(8N^2 - 9) +1

2.

I hated trig.

3.

10k = 4

k = 2/5

YUP its me Ray from Kingston now in Ottawa.

 

[ray_ivory]

Hey guys??


The question 4=10k, The K is a little one like squaring it or cubing it.
I had to find out the answer for K?

 

[ray_ivory]

another one need help with?


(3^-3)^2

4answers to choose from ?

0.3333

0.0014

Ray -- hope all is well and that you are enjoying Ottawa. I am moving to Sydney Australia for good in 2 days and am pumped!

As for the math, I can't remember exactly but I know it is a LOG question.

4 = 10k

therefore Log4 = KLog10
therefore k= Log4/Log10

I am pretty sure that is it ......

HELP GUYS???????????????????????????????

 

[Warik]

HELP GUYS???????????????????????????????

They just gave you all of the answers - how could you possibly need anymore help?

-Warik

 

[ray_ivory]

Warik

There is a new question!!!

Also the question #1 is wrong on the answer.

I had 4 choices on the test to choose from!!!

2N^6+2N^3-2N^5

8N^6+8N^3-8N^5

2N^3

8N^3

 

[Warik]

Why don't you try actually doing the problem before you ask for help?

(3^-3)^2

3^-3 is the same as 1/(3^3)

3^3 is 27

So, 3^-3 = 1/27

What's (1/27)^2?

1/729

which is: 0.0014

I mean shit dude, try doing the problem. It's not like you have to think.

And

2N^6+2N^3-2N^5

8N^6+8N^3-8N^5

2N^3

8N^3

Is not even a question. What are you trying to find?

-Warik

 

[ray_ivory]

Warik,

I did a math exam today for the military communications course.
Those 4 choices are the answers to the question that I had to choose from.I guessed as I couldn't find the right answer.

 

[Warik]

OK - but if you don't tell us what the question is, it will be difficult to tell you whether or not you answered it correctly.

 

[ray_ivory]

(2N)3 x (N3+1) - (2N2)3

the 3's are little ones, cubed and the last 2 in the end is squared!


That is the question.

These are the 4 answers to choose from:
I guessed as I didn't know which was the right one.

2N^6+2N^3-2N^5

8N^6+8N^3-8N^5

2N^3

8N^3

 

[AustinTX]

the last one

once you multiply out the terms you have
+8n^6 at the front which cancels out the -8n^6 at the end, which just leaves the 8n^3

 

[ray_ivory]

FUCK

8N^6+8N^3-8N^5

That was the answer I guessed as I didn't know the right one.

I guess I got it wrong if 8N^3 was the correct answer.

 

[ray_ivory]

Come on guys help out.

 

[slowmoven]

no problem bro,

1) (2n)3 x (n3+1)-(2n2)3 already been done

ans = 8N^3


2) 2 radians = closest degrees

2(pie)r=360degrees
r=360/(2(pie))
r=180/(pie)
radian=57.296degrees
multiple by 2
2 radians = 114.59 degrees

ans = 115 degrees

3) 4=10^k

formula is a^y=X is y=logaX

therefore k=log10 4
k=0.60206

4) (3^-3)^2

=3^(-3 x 2)
=3^(-6)
=1/(3^6)
=1/729

=0.0014

 

[skaman607]

yeah I forgot, in math we take pi as a given so it just slipped my mind
and in the third question I thought you meant 10*k I was wondering why you needed help on that one, and the answer by a ball is correct
