Answer:
a = -1.
Step-by-step explanation:
y = ax^2 - 4x + 3
Convert to vertex form:-
= a(x^2 - 4/a) + 3
= a [ (x - 2/a)^2 - 4/a^2 ] + 3
From this we see that the line of symmetry is y = 2/a so
2/a = -2
-2a = 2
a = -1.
It means that has four of those cubes inside one prism... it's hard to explain but x^3 is ONE CUBE not prism, YOU HAVE FOUR of them, hope this helpz
Answer:
The change in elevation=2,400 feet
Step-by-step explanation:
The expression to determine the change in elevation after 6 minutes is a s follows;
D=S×T
where;
D=change in elevation in feet
S=speed/ descending rate
T=time
In our case;
D=unknown
S=400 feet/minute
T=6 minutes
replacing;
D=400×6=2,400 feet
The change in elevation=2,400 feet
