A. 10p (10 dollars per photo)
b. 75-5
sorry but I can't remember how to do c.:(
Solution for both: (-2,2)
solution for equation one: (0,8)
solution for equation two: (0,6)
Answer:
x is in (0, 17)
Step-by-step explanation:
The compound inequality is ...
0 < x < 17
The "equal to" case is not included on either end, so round brackets are used:
(0, 17)
Answer:
a) X( w ) = 1 /jw - e^-jw / jw
b) X1(t) = 1 for 0.5
X1(t) = 0 for elsewhere
Step-by-step explanation:
x(t) continuous time function = 1
interval ( 0,1 ) also x(t) = 0 outside the given interval
a) Determine the continuous time Fourier transformation of x(t)
x( t ) = u(t) - u(t - 1 )
x ( w ) = 1 /jw - e^-jw / jw
b) supposing x1(t) = x(2t)
x1(t) = u(t) - u ( t - 0.5 )
x1(t) = 1 for 0.5
x1(t) = 0 for elsewhere
One dollar bills size is 2.61 squared inches
and 1 squared inch equals 0.00064516 meter
<span><span>one trillion is: 1,000,000,000,000,000,000
</span>So the size of the dollar bill in meters is:
(2.61)(0.00064516) = 0.0016 squared meters
therefore the area covered by the dollar bills is:
1,000,000,000,000,000,000*<span>0.0016
</span>= 1.6 x 10^15 square meters
that is scientific notation (1.6 followed by 15 zeroes)</span>
