Answer:
$471.65
Step-by-step explanation:
-The value of the laptop after each year is calculated by the formula:
![P_t=P_o(1-d)^t](https://tex.z-dn.net/?f=P_t%3DP_o%281-d%29%5Et)
where:
is the value at time t
is the initial value
is the rate of depreciation
is the time
#We substitute the values to solve for the value after 3 years(2010-2007=3):
![P_t=P_o(1-d)^t\\\\=1500(1-0.32)^3\\\\=\$471.65](https://tex.z-dn.net/?f=P_t%3DP_o%281-d%29%5Et%5C%5C%5C%5C%3D1500%281-0.32%29%5E3%5C%5C%5C%5C%3D%5C%24471.65)
Hence, the value of the laptop in 2010 is $471.65
Let's assume time taken by plane on one way distance as 't'
The total flying time in both directions was 10.5 hr
so, time taken in other direction =10.5-t
now, we are given
A plane averaged 500 mph on a trip going east
so, total distance of one way is
![=500t](https://tex.z-dn.net/?f=%3D500t)
total distance of other way is
![=200(10.5-t)](https://tex.z-dn.net/?f=%3D200%2810.5-t%29)
now, we can that distance is same from both sides
so, we get
![500t=200(10.5-t)](https://tex.z-dn.net/?f=500t%3D200%2810.5-t%29)
now, we can solve for t
![500t=2100-200t](https://tex.z-dn.net/?f=500t%3D2100-200t)
![700t=2100](https://tex.z-dn.net/?f=700t%3D2100)
![t=3](https://tex.z-dn.net/?f=t%3D3)
now, we can find one way distance
![=500\times 3](https://tex.z-dn.net/?f=%3D500%5Ctimes%203)

Answer:
-3x + 9
Explanation:
Because these two integers that is - and - is said to be added and write the sign of of greater or bigger number.
Nonagon - 9 sides
Sum of interior angle of a polygon is (n-2)180 = x
N is the number of sides, so when you plug in 1260 for x, you get 9 for n
Answer:
This is true.
Step-by-step explanation:
Step 1: see that √27 is the same as √3*3*3 and thus 3√3
Step 2: remove parenthesis so that 2(1-3√3) becomes 2 - 6√3
Step 3: observe that the equation now becomes 6√3 + 2 - 6√3 = 2
if you simplify any further, you are left with 0=0, which is true.
