= 8 years * 2 times per year = 16

r = 0.09 / 2 = 0.045

Price (PV) = face / (1 + r)^n

= 1,000 / 1.045^16

= 1000 / 2.02237

= $494.46932, round to $494.47

What is the market price of a Zero Coupon Bond that pays $1,000 face at maturity in 8 years from now?

Current market interest rate (YTM) for such a bond is 9.0% (use semi-annual discounting)
