My college instructor is asking me to define and discuss one of the themes the entire class read about for homework. I've chosen to do a paper on Americanization of the Mexican American woman. However I don't understand how I should define and discuss the...

Given: f(x)=2 cos x and g(x)=sin x. Which of these expressions is equivalent to (fxg)(π/16)? a) cos π/8 b) sin π/8 c) cos π/4 d) sin π/4 Please explain the answer, thank you.

What is 0.7 x 10 = x 10 = 0.07 x 10 = x 10 = 0.23 x 10 = 0.023 x 10 = 0.004 x 10 = 0.404 x 10 =

I have to solve a few systems through elimination, but I'm still not quite sure how to do it.. The first is y=x^2 and y=x+2 Can someone show me how exactly it is worked out so I can try the second one myself?

Hi! I was wondering after you simplify a radical, can you add the rest of the equation to whats outside of the radical? ex. 20 + 10√35 Would that be 30√35 or would it stay as 20+10√35 Thank you in advance, this is really bugging me! :)

(x/x-2)+(x-1/x+1)=-1 So far I was able to get it to x + (x-1) = -(x-2)(x+1) through cross multiplying, but I'm kinda lost with what to do now. Should I convert the right side to a polynomial and add the left side, then bring it all to 1 side so it = 0? Th...

What is Musk’s other energy-based company? Why does he feel this is an equally important company to his electric car innovation? I need help with this question, I don't quite get what its asking

8>7n+1 8-1>7n+1-1 7>7n 1>n * You do not change the sign because you did not divide by a negative. You only change the sign when you do divide by a negative number.

I understand how to do that, thats substitution. How can I solve it with elimination?

Sorry :) I must've gotten something confused. I think I get it now. Thank you!

Ok.. I understand how to eliminate y and everything, then you factor it as normal. The solutions to that equation were (-1, 1) and (2,4). I'm working on another one and used the same steps. y=48x+20 -(y=-x^2+200x+20) and i ended up with : 0=x^2-152x This...

*facepalm* That tricked me. I think it's (152, 7316) & (0,20)? I guess ANY number times 0 is a factor of 0... So I did -152 x 0=0 and -152+0 = -152. That gave me (x-152)(x+0)

Ohhh! Thank you so much!

Thanks. My problem from there is figuring out how to factor it.. I have x^2+x-3=0. Theres no factors of -3 that add up to 1. -3+1 = -2 -1+3= 2 When i try to use the quadratic formula I end up with: (-1+/1(sqrt)13)/2 Am I missing something?

Ahhh! That makes a lot more sense, thanks for the breakdown. I knew I was doing SOMETHING wrong haha. Thanks again :D
