Really, you should consult with your teacher or a tutor. Simply doing these will show you nothing. You need someone right there explaining things as they go along.

That won't help you. E.G. Science and medicine the kinetic energy of praticle of mass m is found by taking one half of the product of the mass and the square of the velocity V Write an expression for the kinetic energy of a particle. m=1/2 [color=#FF0000] KE = (1/2)mv^2[/color] Compare that with what you have written. As I said, you need a complete course of study/ a teacher/a tutor, not just our written solutions to these problems. October 24th, 2008, 08:20 AM   #6

The expression 0.08t + 5.25 represents the monthly long distance bill for a customer who makes t minutes (min) of long distance calling on this plan. Find the monthly bill for a customer who makes 173 min of long distance calls on this plan. You need to work out 0.08(173) + 5.25, i.e., 13.84 + 5.25. The answer is therefore$19.09.

You need to work out 20 - 4(1.5), which is 20 - 6, i.e., 14. The speed of the car will be 14 m/s. October 24th, 2008, 12:27 PM #7 Newbie   Joined: Oct 2008 Posts: 12 Thanks: 0 Re: Can you solve that problems? Thank you very much Tags problems, solve can u solve (0000)=24 algebra
