Answer:

8 people

Step-by-step explanation:

3 people to do the job in 16 hours so each of the people will mow 1/3 of the lawn during the 16 hours.

So if was a single person was mowing the lawn would take them 3 times longer 16*3 =48 hours

To mow the lawn in 6 hours will need 48 hours to be split in 6 hours so will get 48/6 = 8 people.

What’s the radius of center (-2,1) and contains the point (2,-1)
solniwko [45]
<h2>Radius of a Circle Given Center and Point</h2>

To find the radius of a circle when we're given the coordinates of its center and a point it contains, we can use the following formula for distance:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2

  • (x_1,y_1) is one point and (x_2,y_2) is another

<h2>Solving the Question</h2>

We're given:

  • Center: (-2,1)
  • Point: (2,-1)

Plug these given points into the formula for distance:

d=\sqrt{(2-(-2))^2+(-1-1)^2}\\d=\sqrt{(2+2)^2+(-1-1)^2}\\d=\sqrt{(4)^2+(-2)^2}\\d=\sqrt{16+4}\\d=\sqrt{20}\\d\approx4.47

<h2>Answer</h2>

Therefore, the radius of the circle is \sqrt{20} units, or approximately 4.47 units.
