Answer:
Option D. 
Step-by-step explanation:
using a graphing tool
Graph and determine the vertex in each case
we know that
If the equation has a maximum value at x=-2, then the x-coordinate of the vertex must be equal to -2 and the parabola open downward
case A) 
The vertex is the point 
case B) 
The vertex is the point 
case C) 
The vertex is the point 
case D) 
The vertex is the point
-------> is the answer
see the attached figure
Answer:
40
Step-by-step explanation:
Answer:
The area of the circle is 95.03.
Step-by-step explanation:
Diameter is double the radius.
Using the formula for circumference from diameter (c=pi(d)), we find that the circumference of the ferris wheel is about 197.97 feet. We then multiply that number by the revolutions to get 2,374.64 feet, which is the answer.
We can express the recurrence,

in matrix form as

By substitution,

and continuing in this way we would find that

Diagonalizing the coefficient matrix gives us

which makes taking the
-th power trivial:


So we have

and in particular,
