Me . i need with this. i’m getting very very frustrated ! you can get 35 points !

Notes:

 4) maximum

               5) 20.1 ft

               6) 2 seconds

Step-by-step explanation:

4) h(t) = -16t² + 256t

            ↓

            the coefficient is negative so it looks like ∩.  

            Therefore, it has a maximum.

5) h(t) = -16t² + 30t + 6

6) h(t)=-16t²+64t+80

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !
