This is a geometric progression  with a1 = 26,000, n = 5 and r = 1.03

Total earnings in 5 years  =  26000 .  1.03^5 - 1
                                                           ------------    =   138,037.53  (answer)

A student thinks that the regular pentagon in the diagram
Nadya [2.5K]

Answer:

A

Step-by-step explanation:

The student must have thought that every single arrowhead is a line of symmetry, so since there are 10 arrowheads, there must be 10 lines of symmetry. This is incorrect because if you look closely at the diagram, each line has 2 arrowheads, so the student is overcounting by a factor of 2. They should have just counted the number of lines, not arrowheads. Therefore, there must be 10/2 = 5 lines of symmetry, not 10. Hope this helps!
