8 11/12 To solve this you have to convert 8 1/6 to 8 2/12 and 3/4 to 9/12. 8 2/12 + 9/12 =8 11/12

What is the length of LM if L(3,4) and M(1,-2)? Round to the nearest tenth.

kari74 [83]

Answer:

We conclude that the length of LM if L(3,4) and M(1,-2) will be:

$d = 6.3$

Hence, option D is correct.

Step-by-step explanation:

Given

L(3,4)

M(1,-2)

Determining the length of LM

(x₁, y₁) = (3, 4)

(x₂, y₂) = (1, -2)

The length of the distance between (x₁, y₁) and (x₂, y₂) can be determined using the formula

$d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

substituting (x₁, y₁) = (3, 4) and (x₂, y₂) = (1, -2)

$=\sqrt{\left(1-3\right)^2+\left(-2-4\right)^2}$

$=\sqrt{2^2+6^2}$

$=\sqrt{4+36}$

$=\sqrt{40}$

$=\sqrt{4\times 10}$

$=\sqrt{2^2\times \:10}$

$=2\sqrt{10}$

$=6.3$

Therefore, we conclude that the length of LM if L(3,4) and M(1,-2) will be:

$d = 6.3$

Hence, option D is correct.
