Micheal and Peter pratise motocross racing. Michael completes one lap in 22s. Peter does 1 lap in 17 seconds. Michael gets a 176 s head start.

Write the rules expresing the number of laps completed by each racer in terms of the time since the race began.

Please help? This problem has me SO frustrated, even though it sounds so easy. So basically they are asking you for TWO equations dirived from the info.

My Tshirt I was wearing today was bright red. now its laying on the floor in the dark its a dark blacky brown colour...so..what is my t shirts true colour?

Light is the variable so if you take that away you are left with black. This implies that everything is actually black... confused.

I am doing a report for science and one of the parts is the dead sea. I am pretty sure I know how it formed (you can include that if you want), but I don't know when it formed/how old it is. I found one website that said it is 3 million years old, one that said 27 million years old and another that said 5-23 million years old. Please Help!!!!!

hi,, thanks for helping..
so my question involes sine, cosine and tangent.

using a calucaltor how would i find .. lets say sinx = 45 int he interval 0 < x < 560

i cant rember how to do it using that stupid postive quadrent thing,, so do you know the forumla..

like for sin it is 180+x or 360-x (i cant rember this)

so my question... what is the forumula for sin, cos, tan...

A man drops a baseball from the edge of a roof of a building. At exactly the same time, another man pitches a baseball vertically up toward the man on the roof in such a way that the ball just barely reaches the roof. Does the ball from the roof reach the ground before the ball from the ground reaches the roof, or is it the other way around?

An object is in free fall as soon as it is released whether it is dropped from rest, thrown up, or thrown down so I believe they will touch the roof and the ground at the same time.

Any other suggestions?
