Answer 2

For the equation:
y = 20,646 ·  0.86^x
When: x = 11
y = 20,646 · 0.86^11 = 20,646 · 0.19 = 3,929.33 ≈ 3,929
Answer: D ) $3,929
For y = - 5.131 · x²  + 31.821 x - 3.3333
7 am - 5 am = 2 , so: x = 2
y ( 2 ) = - 5.131 · 2² + 31.821 · 2 - 3.3333 =
= - 5.131 · 4 + 63.642 - 3.3333 = -20.524 + 63.642 - 3.3333 = 39.78 ≈ 40
Answer: B ) 40.
