Find the distance between the points (6, 5 square root 2) and (4, 3square root 2).

Answers

For this case we use the distance formula between two points.

We have then:

$d=√((x2-x1)^2+(y2-y1)^2)$

Substituting values in the given equation we have:

$d=\sqrt{(6-4)^2+(5√(2)-3√(2))^2}$

Rewriting the equation we have:

$d=\sqrt{(2)^2+(2√(2))^2}$

$d=√(4+8)$

$d=√(12)$

$d=√(3*4)$

$d=2√(3)$

Answer:

The distance between the points is:

$d=2√(3)$

The distance would be 2√3 , in other words it is 2 square root 3

• Machine s is cleaned every 12 weeks. •Machine that is cleaned every 8 weeks. What is the fewest number of weeks that will pass before both machines are cleaned again in the same week?

Answers

Week 24,assuming that both machines are cleaned at week 0, because multiples of 12 are 12, 24,36. And multiples of 8 are 8, 16, 24. 24 is also the LCM.
