Geo is
an=a1r^(n-1)
2nd term is 12
4th term is 4/3
a2=a1r^(2-1)=12
a2=a1r=12
a4=a1r^(4-1)=4/3
a4=a1r^3=4/3
we have
a1r=12 and a1r^3=4/3
(a1r^3)/(a1r)=r^2=(4/3)/12=1/9
1/9=r^2
sqrt oth sides
1/3=r
the common ratio is 1/3
Answer:
$120
Step-by-step explanation:
930-570=360 (Price difference in 3 years)
360 divided by 3= 120 (Price difference for each of the 3 years)
Answer:
Step-by-step explanation:
Given
___ 
Required
Fill in the gap
First, we need to solve
So:
___
becomes
3.162 ___ 5
3.162 lies between 3 and 4
So, we can say that
lies between 3 and 4
Since:
3.162 is less than 5, the gap can be filled with <.
So, we have: 3.162 < 5
X > 6 i think is the answer
Gravity is inversely proportional to the square of the distance.
In English:
Your weight at the Earth's surface and your weight 850 miles above the Earth's surface decreases by a factor of
(4,750 / 3,900) ^ 2 =
<span>
<span>
<span>
1.483399080
</span>
</span>
</span>
So your weight would decrease by (your weight /
<span>
<span>
<span>
1.483399080
</span>
</span>
</span>
)
If you weigh 180 pounds, at 850 miles above the Earth your weight is
180 /
<span>
<span>
<span>
1.483399080
</span>
</span>
</span>
which equals
<span>
<span>
<span>
121.3429362515
</span>

pounds.
