Question

Find the distance between points P(4, 4) and Q(9, 3) to the nearest tenth

Answer 1

Answer:

$5.1$ units

Step-by-step explanation:

(4, 4) & (9, 3)

To find the distance of two points, we use the distance formula:

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

Let's plug in what we know.

$d = \sqrt{(9 - 4)^2 + (3 -4)^2 }$

Evaluate the parentheses.

$d = \sqrt{(5)^2 + (-1)^2 }$

Evaluate the exponents.

$d = \sqrt{(25) + (1)}$

Add.

$d = \sqrt{(26)}$

Evaluate the square root.

$d = \sqrt{26}$ or $5.0990$ units

Round to the nearest 10th.

$5.1$ units
