can someone check my answer?!?!
Jane bought a car for $30,303. The value of the car depreciated at a constant rate per year. The table below shows the value of the car after the first and second years:
Year 1 2
Value (in dollars) 25,757.55 21,893.92
Which function best represents the value of the car after t years?
f(t) = 25,757.55(0.85)t
f(t) = 30,303(0.85)t
f(t) = 30,303 (0.15)t
f(t) = 25,757.55 (0.15)t

A is just 2+5 = 7 --- rational
B is 2 + sqrt(2) --- irrational since sqrt(2) is irrational (can't write it as a fraction)
OpenStudy (afloridagirl):
so c

right?

since:
\[3^{\frac{ 3 }{ 2 }} = (3^{\frac{ 1 }{ 2 }})^{3} = \sqrt{3}^{3} = \sqrt{3^{3}} = \sqrt{27}\]
sorry my bad, answer is d
