Write the expression (2x)(4y) + 9x + 10y + (8x)(4y) in a simpler form, if possible. I've tried this problem several times, and have gotten the wrong answer. Someone help?

Thank you very much

Would changing the frequency of a wave cause a change in amplitude? I would say only if the wave velocity remains the same because if the frequency increases, vibrations increase and then amplitude would decrease, correct? If I had a wave diagram will 4 complete waves showing ...

Would changing the frequency of a wave cause a change in amplitude? I would say NO because they don't affect each other, correct? If I had a wave diagram will 4 complete waves showing and it said the diagram represented 4 sec in time the frequency would be 1cycle/ per seco...

Roughly twice the gravitational acceleration of 9.8 to stop in have the time. Given F=MA then F = 48*19.6 or about 950 (kg*m/(S^2)). SOmeone helped on the facebook page: diving news by flipnripcom
