Question

What is the distance between (2,9) and (1,5)

Answer 1

Answer:
`d=√(17)`

Step-by-step explanation: Since the distance formula is
`d=\sqrt{(x_(2)-x_(1 ))^(2) + (y_(2) -y_(1))^(2)`, You need to plug in the values. You'll then get
`d=√((1-2)^2+(5-9)^2)`. (1-2) equals -1 and 5-9 equals -4.
`d=√((-1)^2+(-4)^2)x^(2)` The next step is to solve the exponent.
`d=√(1+16)` Then you just need to simplify.
