Answer:
2.225
Step-by-step explanation:
To find how long the object will be in the air, we just need to find the time when the object reaches the ground, that is, f(t) = 0
So, we have that:
0 = −16t2+32t+8
2t2-4t-1 = 0
Using Bhaskara's formula:
Delta = b2 - 4ac = 16 + 8 = 24
sqrt(Delta) = 4.899
t = (-b + sqrt(Delta)) / 2a
t = (4 + 4.899) / 4
t = 2.2248
Rounding to nearest hundredth, we have t = 2.225
She could have two groups of five (5*2=10), or five groups of two (2*5=10).
