Answer:
The vertex is the point (6,-31)
Step-by-step explanation:
we have
This is a vertical parabola open upward
The vertex represent a minimum
Convert to vertex form
Complete the square
Rewrite as perfect squares
-----> equation in vertex form
therefore
The vertex is the point (6,-31)
Using continuous compounding, we have:
90000=65452 x e^.091t
1.3750534743017784024934303000672=e^.091t
ln 1.3750534743017784024934303000672=ln e^.091t=.091t ln e=0.091t
t=3.5 years
A) 1.75p + 12 = 54
1.75p = 42
p = 24 bags
b) 1.75(70) + 12 = b
122.5 + 12 = b
b = $134.50
