Question

Can someone please help me with this question?

Answer 1

PQ = 9.4

Explanation:

to solve for PQ, use the distance formula

d =
`\sqrt{(x2-x1)^(2) + (y2-y1)^(2) }`

use two points

(x1,y1) = (4,3)

(x2,y2) = (-4,-2); and substitute into distance formula

d = PQ =
`\sqrt{(4+4)^(2) + (3+2)^(2) }` =
`\sqrt{8^(2) +5^(2) }` =
`√(64+25)` =
`√(89)` = 9.4
