Question

What is the distance between points S and U ? Round to the nearest tenth of a unit

Answer 1

The answer too this problem is C.

Answer 2

Answer

Find out the distance between points S and U .

To prove

Formula

$Distance\ formula = \sqrt{{(x_{2} - x_{1})^{2} +{(y_{2} - y_{1})^{2} }$

Two points be S(2, 1) and U(6,8) .

Put in the formula

$Distance\ formula = \sqrt{{(6- 2)^{2} +{(8- 1)^{2} }$

Solving the above

$Distance\ formula = \sqrt{{4^{2} +{7^{2} }$

$Distance\ formula = \sqrt{16+49}$

$Distance\ formula = \sqrt{65}$

$\sqrt{65} = 8.1units (approx)$

Distance formula = 8.1 units (approx)

Therefore the length from S to U be 8.1 units (approx) .

Option (c) is correct .
