Answer:
D. The parallel bases remains parallel
Step-by-step explanation:
Reflection is an example of solid transformation in which an object is turned about a line or point to produce its image. Though the initial orientation of the given object changes, but its shape and size is preserved.
A trapezoid is a quadrilateral. If it undergo reflection across the x-axis, then y-axis; its parallel bases would remain parallel. Though the initial orientation of the trapezoid would have changed.

Answer: Approximately 6.58 years old</h3>
The more accurate value is 6.57881347896059, which you can round however you need. I picked two decimal places.
==================================================
Explanation:
Let's pick a starting value of the car. It doesn't matter what the starting value, but it might help make the problem easier. Let's say A = 1000. Half of that is 1000/2 = 500.
So we want to find out how long it takes for the car's value to go from $1000 to $500 if it depreciates 10% per year.
The value of r is r = 0.10 as its the decimal form of 10%
t is the unknown number of years we want to solve for
---------------------------
y = A(1 - r)^t
500 = 1000(1 - 0.1)^t
500 = 1000(0.9)^t
1000(0.9)^t = 500
0.9^t = 500/1000
0.9^t = 0.5
log( 0.9^t ) = log( 0.5 )
t*log( 0.9 ) = log( 0.5 )
t = log( 0.5 )/log( 0.9 )
t = 6.57881347896059
Note the use of logs to help us isolate the exponent.

Answer: 0.125%
Step-by-step explanation:
Let 1600 corresponds to the 100% value and 2 is a part of the total 100% value 1600.
The formula to find the percent of a part :_

Substitute Part= 2 and Total = 1600 in the formula, we get :-

Therefore, 2 is 0.125% of 1600.
Hence, the percent of 1600 is 2 = 0.125%
