Answer:
D)   
Step-by-step explanation:
First we have to factorize and then cancel the like terms.
Given,

Now, we got the like term  (x-1).
Canceling this like term we get

 
        
                    
             
        
        
        
A. 
the starting point is where t=0
d(0)=-16(0)^2+96(0)+112
D(0)=112
started from 112 feet 
b. max height is vertex 
for 
y=ax^2+bx+c
the x value of the vertex is -b/2a
so
D(t)=-16t^2+96t+112
t value of vertex is -96/(2*-16)=3
it reaches after 3 seconds
C. simpliy evaluate D(t) for t=3
D(3)=-16(3)^2+96(3)+112
D(3)=-16(9)+288+112
D(3)=-144+400
D(3)=256
max height is 256ft
        
             
        
        
        
=3ax-11a-9x
Hope this helps
        
             
        
        
        
Answer:Coming out like this the normal vectors are going to be parallel to one another. So it's easier for me to test to see whether the normal vectors are parallel.
