Math
So I just round it ? Yep thanks

Math
Btw related to the question I asked: how long would it take him to return to his starting point in a direct line if he can run at 10 km per hour?

Math
Thank you so much ! :D

Math
A runner is 22 km east and 15 km south of his starting point. How far is he in a direct line from his starting point?

Physics
A 1.9 kg ball is attached to a ceiling by a string. The distance from the ceiling to the center of the ball is 1.13 m, and the height of the room is 3.00 m. (a) What is the gravitational potential energy associated with the ball relative to the ceiling? J (b) What is the gravi...

Physics
An object with a weight of 30 newtons is placed on a flat, level surface. What is the normal force that the surface pushes on the object with?

Math
Another way to write 44n would be 44 x n because you are multiplying 44 by n, not dividing them.

Fractions
I'm pretty sure it would have traveled 18.5 miles. Try drawing it out on a graph (7.5 down, 3.5 right, etc.). Then add up all the distances it traveled right up to where it reaches a position where it already went. Hope this makes sense.

Math- Calculus
Locate the absolute extrema of the function on the closed interval: y= 4/x+tan(pix/8), [1,2]

Math
First you have to find the derivative of g(x). Then set that equal to 0 and solve for the value(s) of x. Then plug your critical #'s into the original equation. The largest # will be your relative max and the smallest # will be the relative min.
