Physics
A person skateboarding with a constant speed of 1.30 m/s releases a ball from a height of 1.25 m above the ground. Given that x0 = 0 and y0 = h = 1.25 m, find x and y for (a) t = 0.250 s and (b) t = 0.500 s. (c) Find the velocity, speed and direction of motion of the ball at t...

ammmmmmmm

french exam tomorrow, WHAT DO I DO?!
Just study i know you should get some sleep but if you don't study you will fail just study study study

math
1/3+ (-5/6)+(-1/2) = 2/6-5/6-3/6 = -6/6 =-1

math
-6/7,-1/2,1/7,2/7,3/7

math
Two odds =even, ex: 1+1=2, 5+9=14, 77+3=80 ... you always get an even when adding two adds 1odd+1even =odd ex: 2+5=7, 11+8=19, 101+2=103 ... you always get an odd,

math
1 is an odd number, but 1 doesnt count for prime number, if this is the rule you were thinking about

math
let spped of current be X, when the boat goes upstream, the actual speed of boat= speed of boat-speed of current;when the boat goes downstream, the speed =speed of boat+speed of current distance=speed x time upstream: (16-X)x 1/3 downstream:(16+X)x1/4 since the total distance ...

geometry
1,2,6,24,120,..[720,5040] 2/1=2, 6/2=3,24/6=4,120/24=5, what you need to find out is a number that can be divided by 24 and gives you 6, 2,4,8,16,32,.. [64,128] each number times 2 gives you next number 1,1/4,1/9,1/16,1/25,.. [1/36,1/49] the denominators are 2 square, 3 square...
