I'm guessing that you want to calculate the middle horizontal line.
The upper left triangle on the left is a 45 45 90 triangle.
The hypotenuse is 12 and so the leg is 12 * (1/square root of 2)
leg = 12 *
<span>
<span>
<span>
0.7071067812
</span>
</span>
</span>
leg =
<span>
<span>
<span>
8.4852813742
</span>
</span>
</span>
So that means the line =

16.9705627485

It should be 23 square foot.
Answer is (B) 6
Reason
3 x 6 = 18 (area)
3 + 3 + 6 + 6 = 18 (perimeter)
Answer:
Step-by-step explanation:
Use the info given in the exponential equation to find the value of b, the rate of decay.
where v(t) is the value of the car after a certain number of years, t, have gone by, a is the initial value, and b is the rate of decay. We have everything we need but b:
a = 20000
v(t) = 16000 after t = 1 year:
so
b = .8 Taken in context, this means that the car depreciates 20% each year. Now we can solve the problem being asked of us, which is to find the value of the car after t = 5 years:
which simplifies down a bit to
v(t) = 20000(.32768) so
v(t) = 6553.60, choice C.
Answer:
37
