A shark jumps out the water. The quadratic function f(x) = −16x2 + 19x models the shark's height, in feet, above the water after x seconds. How long is the shark out of the water?

The answer is c because you turn 17.5% into a decimal which gives you .175 then you times that by $361.35 which gives you 63.23625 but then you round that which gives you 63.24. then you at 63.24 pulse 361.35 and you round it which gives you $425

than do 23.50 times 18 and then divide your answer by 100 than you will get x.
