For the radius it is supposed to be r^2. Would I use 10.0cm^2 or 5cm^2? and would I convert that value to meters? Also where did the 1.41s come from? Thank you

Four identical masses of 800kg each are placed at the corners of a square whose side length is 10.0cm. What is the net gravitational force (magnitude and direction) on one of the masses, due to the other three? I think I have to separate the four masses but I'm not sure ...

p. 942 #5 This is a three-part question: a. the graph y = f(x) in the xy-plane has parametrization x=x, y=f(x), and vector formula r(x) = xi + f(x)j. Use this to show that if f is twice-differentiable, then k(x) = ((absvalue f''(x))/[1+((f'(x))^2]^3/2 b. use the ...

The greater of two consecutive even integers is six less than twice the smaller. Find the integers. The greater of two consecutive even integers is six less than twice the smaller. Find the integers How about x + 2 = 2x - 6 almost .. it's x + (x+2)=2x-2

**Math**

The greater of two consecutive even integers is six less than twice the smaller. Find the integers. Let the smaller be x. That means that the larger is x+2. From your statement x+2=2x-6 Solve for x. I hope this helps. Thanks for asking.
