To calculate the TIME that a maximum height occurs, you should use: 

• -b/(2a) 

• Quadratic formula 

• the c value 

• 0

For that same projectile, at what TIME does the maximum height occur? 
h(t) = -16t² + 20t + 6 

• 0 seconds 

• 625 seconds 

• 160 seconds 

• 2 seconds 

To calculate the maximum height, you should: 

• Use the time you got from -b/(2a) and plug it in for each "t" 

• -b/(2a) 

• use the c value 

• use the b value
