A quantity U is the sum of two terms, one party constant and the other veries directly as the square of V. if V=2 when U=35 and V=5, U=203. Find the value of V and U=515

2 answers

V=7.5
U=515

AAAaannndd the bot gets it wrong yet again!

u = av^2 + b
so
4a+b = 35
25a+b = 203
a=8, b=3
u = 8v^2 + 3
so when u=515,
8v^2+3 = 515
v = 8
