Find the length of segment JK with endpoints J(4, 8) and K(-1, -2). Leave the answer as a radical. Simplify if necessary

The length of segment JK is 5 ⇒ C

Step-by-step explanation:

The formula of the distance between the two points (x1, y1) and (x2, y2) is

d =

Let us use the formula above to solve the question

∵ Jk is a line segment

∵ J = (4, 8) and K = (-1, -2)

∴ x1 = 4 and y1 = 8

∴ x2 = -1 and y2 = -2

→ Substitute them in the formula above

∵ JK =

∴ JK =

∴ Jk =

∴ Jk =

→ Simplify the root

∵ 125 = 5 × 5 × 5

∴ = 5

∴ JK = 5

∴ The length of segment JK is 5

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )
