Is speed and velocit y the same thing?
Speed is how fast something is going. Velocity is the speed and direction something is going.
[ 3x + 3x + y + y ] isn't a question, so it doesn't need an answer. But you can clean it up and make it shorter. -- Remember that 3 of anything plus another 3 of the same thing is 6 of them, so 3x + 3x = 6x . -- Then remember that 1 of anything plus another one of the same thing is 2 of them, so y + y =…
A motor boat can go 2 miles downstream on a river in 3 minutes it takes 15 minutes for the boat to go upstream the same 2 miles find the speed of the current?
Let boat speed = X and current speed = Y Downstream speed = boat speed plus current speed = X + Y Upstream speed = boat speed minus current speed = X -Y Downstream speed = 2 miles divided by 3 minutes = 2/3 miles per minute Upstream speed = 2 miles divided by 15 minutes = 2/15 miles per minute X + Y = 2/3 X - Y = 2/15 add equations 2X =…
A sailor goes 8km downstream in 40 minutes and returns in 1 hours Determine the speed of the sailor in still water and speed of the current?
No, it is not. The y-intercept is the point where a function is evaluated as x=0. The point symmetrical to that is the one the same distance from the origin along the y-axis. For example, in the function y = 3x + 2, the y=intercept is (0,2) and the point symmetrical to that is (0,-2) Also, the x-intercept is when y=0 (solving for x) ■
What is the effect on the graph of the equation y equals x2 plus 1 when it is changed to y equals x2 plus 5?
The actual definition of Addition is when you total the amount of objects you have in your possession. So when you take the addition of one thing to another, you have x + y. x, being the one thing, y being another. In simple terms. If Another and One Thing are the same object, then you could also say this... x + x = 2x. Meaning, you have two of those things in your possession…
In most case statements you cannot be certain how the data will be presented; both n and N mean essentially the same thing, as do y and Y. Therefore, the case statement will check for both variations of the information because they mean the same thing (but in Unix they are case sensitive and would be considered different values otherwise).
