Hey guys! I'm having problems with some problems regarding the distance formula and I am thoroughly stumped, so I kindly ask for help please. I'm fine solving distance without roots but when the roots came in I became lost.
*don't know how to do the square root symbol on here so I will just put, a "*" before the square roots.
1) (0, -*3) and (*5, 0)
Square Roots: negative square root of 3 (the negative is on the outside), and square root of 5
2) (3*3, *5) and (-*3, 3*5)
Square Roots: (3 square root of 3, square root of 5) and (negative square root of 3, 3 square root of 5) Sorry about the lack of square root symbol! Thanks!
for the first one you're trying to find the distance between the pointsand
.
All you have to do is use pythagorus' theorem, you form a right angled triangle with sides of lengthand
find out the length of the hypotenuse (and hence the distance between the points)
so
