Answer: 
Step-by-step explanation:
The acceleration
of the satellite can be calculated by the following equation:

Where:
is the final speed of the satellite
is the initial speed of the satellite (it was "stationary" before the release)
is the time
Isolating
:


Finally:

1. The answer would be about 20.72, or 20.7142 if you don’t want the rounded version
2. The answer is -12.8
44 inches.
All you have to do is find out what 10% of 40 is then add it back to 40. In the case of finding 10% of something you just “chop” of the back number (or move the decimal place forward) so 10% of 40 is 4. The. 40+4=44.
You can also multiply fractions to find the percent of a number but that is not necessary in this case.
71290 because the ones are 0 and zero is lower than 5
so it wouldn't add anything to the tens
the rule is if the number is more than 5+ it will add 1 to the next number
for example if we have this number 189 and we want to round it to the nearest 10 ..
we will see the ones place is it more than 5+ ? YEAH bcz its 9 ...
so 9 will add one to the tense and the answer will be 190 :)
hope you got the point .
1. 4 times 6
2. 8 divided by 2
3. 4 squared 2
