Answer:
68km
22miles
240km
Step-by-step explanation:
The question here is how long does it take for a falling
person to reach the 90% of this terminal velocity. The computation is:
The terminal velocity vt fulfills v'=0. Therefore vt=g/c,
and so c=g/vt = 10/(100*1000/3600) = 36,000/100,000... /s. Incorporating the
differential equation shows that the time needed to reach velocity v is
t= ln [g / (g-c*v)] / c.
With v=.9 vt =.9 g/c,
t = ln [10] /c = 6.4 sec.
There are many expressions equivalent, it just needs the answer to also equal 2.
2×1
3-1
4÷2
1+1
so on
Step-by-step explanation:
Multiply $78 by by 65/100 to determine the original price.
78 can be put over 1.
<u>Multiply</u><u>:</u>
<u>Simplify by dividing the numerator and denominator by 100:</u>
The original price was $50.70.
The answer here is B. -16
10 + -16 equals -6 and a negative divided by a negative is a positive so -6 divided by -3 is -2.
Hope this helps!
