Given:
The vertices of a polygon are A (−1, 1), B (4, 1), C (4,−2), and D(−1,−2).
To find:
The perimeter of ABCD.
Solution:
Distance formula:
Using distance formula, we get
Similarly,
Now, perimeter of ABCD is
Therefore, the perimeter of ABCD is 16 units.
I’m not sure tbh,but you can use the app photomath and it should tell you!
Answer:
x =196
Step-by-step explanation:
A) You can drop hammer and a feather, both will reach ground at the same time ( it was actually done in Apollo mission)
b) i. Yes, it is similar to weightlessness experienced by astronauts
ii. The phenomenon of "weightlessness" occurs when there is no force of support on your body. When your body is effectively in "free fall" in roller coaster, accelerating downward at the acceleration of gravity, then you are not being supported.
Just like astronauts in space feel no force of support that we on earth feel due to gravity.
