Question

Point P has coordinates (-4,-2)and point Q has coordinates (4,3). ( on a 1cm grid )

Answer 1

Answer:

PQ ≈ 9.4 cm

Step-by-step explanation:

Calculate the distance d using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = P(- 4, - 2) and (x₂, y₂ ) = Q(4, 3)

PQ = $\sqrt{(4+4)^2+(3+2)^2}$

     = $\sqrt{8^2+5^2}$

     = $\sqrt{64+25}$

     = $\sqrt{89}$

     ≈ 9.4 cm ( to 1 dec. place )

Answer 2

Answer:

the square root of 89 is 9.4 so thats your answer
