Umnica [9.8K]

Answer:

the handle will end up on the left side

Step-by-step explanation:

The cup is rotated 180 degrees clockwise. Therefore, I assume the rotation is about the center of the bottom of the cup. Also, only the cup is rotated, not the saucer (although this makes no difference in this problem).

The result is that the handle will end up on the left side. The cup will still be right side up.

What is the distance between (−10, −2) and (−4, −2) ? −14 units −6 units 6 units 14 units
Lesechka [4]

Answer:

6 units

Step-by-step explanation:

to calculate the distance d between the points use the distance formula

d = √(x₂ - x₁ )² + (y₂ - y₁)²

with (x₁, y₁ ) = (- 10, - 2) and (x₂, y₂ ) = (- 4, - 2)

d = \sqrt{(-4+10)^2+(-2+2)^2} = \sqrt{6^2+0^2} = \sqrt{36} = 6
