19.7136 :)  If you are using a calculator just do this - (the #)^2  :)

Thank you Nataszaa for ur points!a point for u from me too!

No its all okay!i too answer a question twice(only if i havent seen)!

i was just telling anonymous to stop posting that quetion so many times!

Sorry, rosala....I didn't see this had already been answered.....let me make the answer clear......

0.0529 ......!!!!!!!!!!!!

OK...so we have  (-0.23)² = 0.0529

No problem :)

Thank you!:)  I have been really trying to understand them and I think I got the concept down!  Thanks for all the help :)

thanks

Yep...your setup and answer are correct....I think you're getting the hang of these trig problems!!!

i think u should stop posting them again and again!

I just went off of the diagram.  We have one angle and the opposite side, and we are trying to find x (the adjacent side) I belive. :)

Hey....Rose98....give us the whole question....I don't see what is being asked for....

Well first we have to convert 8.30 GB to MB

8.30 GB = 8300 MB

Then add 8300 MB to 15.2 MB

8300+15.2=8315.2MB

and if you need your answer in GB then it would be 8.3152GB

:) hope this helps!

Good then!becoz u dont seem happy without those sunglasses!

Yeah, rosala.......kitty<3 has "borrowed" a lot of them from me, too!!!!!!

That's OK........I have an endless supply!!

See???

Convert MB to GB. 1 GB= 1,024 MB

9-5(-3z(6) + 8k(-2))

4+(-9+(-16))

4+(-25)

-21

-0.23^2=529/10000

529/10000=-0.0529 :)

Hope this helps 

Someone please correct me if I am wrong but I belive the equation should be set up like this - tan(33)=7000/x

0.649407593198=7000/x

x=10779.0547466939433696

and then simplify it too x = 10,779feet :)

i think becoz many people including me have borrowed ur sunglasses!

Yes!We are!

Sorry....I always forget about that, Nataszaa....I always assume the variables are positive, but I shouldn't!!! ......Your instuctor is correct!!!

To see why this is, suppose we have:

√(a²)  where "a" is negative.......If we evaluate this as just "a," we will get a negative value out of a positive square root, which is impossible!!!....

So the correct thing is......... l a l

Thanks for reminding me about this.....I'll have to put this one in my "memory bank" so I don't repeat that error!!!   

No sunglasses for this one!!!

Exactly :) we are a good team ;)

Ya ur right!And thats called a team work!

Hahaha thats ok.  Everybody makes mistakes :)  I actuly did the same thing fist time I calculated it :P hahaha  At least we got it figured out!
