physics
Acceleration is the change in velocity over time: Acceleration = (Final velocity - initial velocity)/time Since there are no directions involved, speed is used instead of velocity. So you know the initial speed: Initial speed = 53800 m/s And you know the final speed: Final spe...
MATH
Just start at 2 and divide 255 which is (2^8)-1. 255/2 =127.5 Not divisible by 2. 255/3 = 85 We have one prime number, 3. 255/5 = 51 We have two prime numbers - 3,5. 255/7 = 36.43 Not divisible by 7 255/9 = 28.33 Not divisible by 9 255/11 = 23.18 Not divisible by 11 . . . 255/...
MATH
You have to break 1260 down into it's number tree. Start by dividing the number by 2 until you can't do it evenly, then divide by 3, and so on until no more divisions can be made: 1260/2 = 630 So we have one prime factor, 2 and are left with 630: 630/2 = 315 Now we hav...
MATH URGENT
In either case though, you have to think. How many even or odd numbers are there between 1-100? The answer is 50. So in order to guarantee the removal of an even number 51 integers must be randomly removed.
MATH URGENT
You may have to clarify, do you mean how many times will this have to be done to guarantee the removal of an even or odd integer? Because just removing one integer guarantees the removal of an integer.

Again, we start with the question: What would the final speed of a car be after 5.0 seconds with a starting speed of 50 mi/hr? What is needed to solve this equation: Acceleration of the car. Yes that is all that is necessary. To find the acceleration, this is where the 0-60 mi...
