A. triangle is isosceles in several ways. We will show that |AC|=|BC|. We can use the Pythagorean Theorem to check that these both have length 22+32−−−−−−√. In the calculations below M=(3,1) is the midpoint of AB¯¯¯¯¯¯¯¯.
|AC|2|BC|2=|AM|2+|MC|2=22+32=|BM|2+|MC|2=22+32.
We can also observe that to get from A to C we go over (to the right) by two units and then up three units. To get from B to C we go over (to the left) by two units and then up three units. We travel the same distance to get from A or B to C so A and B are equidistant from C. Finally, we can draw the horizontal line of symmetry for △ABC:

Answer: After 7 years, the value of the sailboat is $3045.49.
Step-by-step explanation:
Since we have given that
Original value of the sailboat = $9500
Depreciation rate = 15%
Number of years = 7
As we know the formula for "Compound Interest "i.e
where,
A denotes Amount
P denotes original value
r denotes rate of depreciation,
n denotes number of years.
So, our equation becomes ,
Hence, after 7 years, the value of the sailboat is $3045.49.
