Question

Help please thanks please. Solve for the value of d to the nearest tenth place

Answer 1

d = √74

d = 8.6 (to the nearest tenth place)

Explanations:

Given the expression to calculate the distance between the coordinates (-2, 1) and (5, -4) as shown:

`d=AB=√((5-(-2))^2+(-4-1)^2)`

Simplify

`\begin{gathered} d=√((5+2)^2+(-5)^2) \\ d=√(7^2+5^2) \\ d=√(49+25) \\ d=√(74) \\ d\approx8.6 \end{gathered}`

Hence the simplified form of the expression is √74 or 8.6
