Given,
x=3 and y=-2
Now,
x^2-3xy+1/2y^2
= 3^2-3×3×(-2) +1/2(-2)^2
= 9+18+4/2
= (18+36+4) /2
= 58/2

Answer:
Sonji is 0.5 miles far from the finish line
Step-by-step explanation:
Data provided in the question:
Distance between the Sonji and the finish line = 0.4 miles
Distance run by Sonji back = one tenth of a mile
i.e =
miles = 0.1 miles
Hence,
The total distance of Sonji from the finish line will be
= Distance between the Sonji and the finish line + Distance run by Sonji back
= 0.4 miles + 0.1 miles
= 0.5 miles
Hence,
Sonji is 0.5 miles far from the finish line
