Re: Problem help
Hi Pinku:
r^2 = 0.924262
Solve for r by taking the square root of both sides.
|r| = ?0.924262
r = ±?0.924262
r can be the square root of 0.924262, or the opposite of the square root of 0.924262, or both, depending upon what the symbol r actually represents.
For example, if r is the radius of a circle, then you want the positive square root because radius is a distance and distance is never negative.
If r is a rate, then it very well might be negative, depending upon the exercise.
If the exercise is purely mathematical, then both roots are required.
To determine the actual decimal value of ?0.924262, use technology (eg: calculator, computer).
