5 - sqrt of 20x + 4 >= -3 5- 20x + 4 >= -3 5-4 - 20x >= -3 1 - 20x >= -3-1 -20x >= -4 x<= -15 Possible answers are x<=3 -1/5 <= x<= 3 x >= -1/5 x >= 0 I think it is -1/5<=x<=3 because both solutions work

Posted by Juliette on Sunday, October 10, 2010 at 4:58pm. Hi-I have a question-we're studying Newton's Laws and my question is: If I have a constant, non-zero force, how does the accleration change as the mass is changed. I think it changes proportionally-because the ...

**Physics-Newton's Law**

Hi-I have a question-we're studying Newton's Laws and my question is: If I have a constant, non-zero force, how does the accleration change as the mass is changed. I think it changes proportionally-yes, or no but I'm not sure why except to say that's the law

A shopper pushes a grocery cart 20m at constant speed on level ground against a 35N frictional force. He pushes in a direction 25 degrees below the horizontal. What is the work done on the cart by gravity? I know you can use W=Fdcos(theta) where F=mass*gravity. BUT, no mass is...

**prob.**

If it is given that P(A)=1/3 and P(B/A)=2/3 (the dividing sign is ment to be a vertical bar), what is P(A and B). I got .07. Is this correct? If it isn't, why not?
