Pre-calc 12 problem? Need help?
HI everyone, I'm not sure how to start this question and I need some help!
B) Solve this equation algebraically where 0<x<2pi. Give answers as exact solutions.
Sqrt(2)Cos^2x - cosx =0
Can I factor a Cosx out? Or does the Root 2 prevent me from doing that? I'm so confused! Thanks for any help.
1 AnswerMathematics7 years agoFinding Y-intercept of y=(3x/x+4)-5?
I made x=0
So I end up with:
y= (0/4)-5
Does the divide by zero mean the graph doesn't cross the y-axis? Would I say y is undefined?
Thanks for your help!

1 AnswerHair7 years agoWhen I google my name, another person's profiles w/ the same name appear. Worried employers will see her profiles instead?
I'm applying for jobs right now and I wanted to google my name to make sure all my social media was clean (making sure an employer wouldn't see any off colour jokes in my profile etc.) but when I type in my full name another girl's profiles appear b/c she has the same name as me. However all her profiles are racist/ have extensive profounities/ reference taking illegal drugs, etc. I'm worried potential employers will google my name and come across her profiles thinking that it's me! I don't know what to do, any advice?

1 AnswerMathematics7 years agoIf the job description for sales associate and keyholder are EXACTLY the same, is it safe to assume I can apply for Keyholder?
A place I'm looking at apply for is hiring a keyholder and nothing else. I'm not really sure I qualify because I've never been a keyholder before. However I looked at the job description of a sales associate from their job openings in other cities and the job description was word for word the same as the keyholder. Is it safe to assume that I can apply to be a keyholder?

1 AnswerDiet & Fitness7 years agoSimplifying Rational Expression?
The Question is:
6a^2 - 15a / 6a - 15a^2
Basically as far as I got was factoring 'a' from the numerator and denominator to get
a(6a-15) / a(6-15a)
but now I'm confused because I can't cancel the top and bottom term, if you could explain that would be really helpful... could you help me out? Thanks :)

3 AnswersOther - Outdoor Recreation8 years agoWhat would be a good everyday lip colour for me?
It seems whatever lip colour I try it always looks wrong on me and I'd like to get a fun lipstick shade that I can wear everyday and have it look right. I like deep red lipsticks but they're a little dapper for the daytime. Here are same pictures of me:
What lip colours would work for me? My hair is naturally dirty blonde but I've dyed it red with henna. I've tried Coral lipstick but it makes my lips look like I have an infection!

I began working out my arms a few months ago because I've always been uncomfortable how I gain weight in my upper arms and it makes them look disproportionally large.

1 AnswerDiet & Fitness8 years agoToo late to start computer programming?
I'm 18 years old and female, so growing up my parents never got me into computers but instead more "girly" ventures. But now I'm starting to become more interested in the field of programming but I'm worried that if I choose to make it my career I won't be able to compete with people who have been programming since their early teens. Is it too late to start? If not, where should I start? I'm interested in HTML and CSS mostly... More web design.
