Answer:
2
Step-by-step explanation:
i think
The first thing we are going to do in this case is to rewrite the function:
f (x) = - 16x ^ 2 + 48x
We look for the first derivative:
f '(x) = - 32x + 48
We match zero:
0 = -32x + 48
We clear x:
32x = 48
x = 48/32 = 24/16 = 12/8 = 6/4 = 3/2
x = 3/2
We verify if this value is a maximum or minimum with the second derivative:
f '' (x) = - 32
We evaluate in x = 3/2:
f '' (3/2) = - 32 (<0 Is a maximum)
Therefore the maximum height is reached in:
x = 1.5 s
The height is:
f (1.5) = - 16 * (1.5) ^ 2 + 48 * (1.5)
f (1.5) = 36 feet
Answer:
The maximum height of the ball is:
36 feet
and it takes the ball to reach that height about:
1.5 s

Answer:
The answers that apply are A (x=-2) and C (x=1),

Step-by-step explanation:
Actually , x= -2 apply because
If you look at the graph you will see that f(-2)=1.
See the point with coordinates (-2 , 1).

Stack 1 : 2^0 = 1 quarter.
Stack 2 : 2^1 = 2 quarters.
Stack 3: 2^2 = 4 quarters.
Stack 4: 2^3 = 8 quarters.
Stack 5 : 2^4 = 16 quarters.
Stack 6: 2^5 = 32 quarters.
1 + 2 + 4 + 8 + 16 + 32 = 63
Answer: She used 63 quarters.
