Question

use the distance formula to find the distance between c(-10,1) and D(5,5). Thanks

Answer 1

d = sqrt((x2-x1)^2+(y2-y1)^2)

in this case:

sqrt((5 - -10)^2 + (5-1)^2) =

sqrt((15)^2 + 4^2) =

sqrt(225+16) = sqrt(241) ~ 15.52

Answer 2

i would use the pythagareom(sp) formula

a^2 + b^2 = c^2

15^2 + 4^2 = c^2

225 + 16 = c^2

c = 15.524

Answer 3

= √(-10-5)² + (1-5)²   (note: the whole thing is squarerooted.)

= √(-15)²  + (-4)²

= √241

= 15.524

Answer 4

d= square root of x2-x1 squared plus y2-y1 squared so if you plug in the numbers you get

(5-(-10) squared + (5-1) squared which works out to the square root of 241 which is 15.4
