Answer:
Since weight is directly dependent on the acceleration of gravity, things on the Moon will weigh only 16.6% (≈ 1/6) of their weight on Earth.
Step-by-step explanation:
Being that the moon has a gravitational force of 1.622m/s2, we multiply the object's mass by this quanitity to calculate an object's weight on the moon. So an object or person on the moon would weigh 16.5% its weight on earth. Therefore, a person would be much lighter on the moon.
have a nice day /night\
may i please have a branlliest
Step-by-step explanation:
let
(-7,-8) =(x1, y1)
and (-6,7)=(x2, y2)
by the formula
d=√(y2-y1) ²+(x2-x1) ²
=√(7+8)²+(-6+7)²
=√15²+1²
= √225+1
= √226
<span>43.586 to the nearest tenth is 43.6. That is because 43.586 is greater than 43.55 and we have to increase the tenth value for 1. And 43.586 to the nearest hunderth is 43.59. That is because 43.586 is greater than 43.585. Finally, 43.586 to the nearest whole number is 44 ( 43.586 is greater than 43.5 ). Hope this helps. Let me know if you need additional help!</span>
Answer:
Step-by-step explanation:
Hello!
(5x+4) /( (x-4)( x+2))
(5x+4)/ (x² +2x -4x -8)=
(5x+4) /( x²-2x -8)
