Step-by-step explanation:
f(x) = −16x^2 + 24x + 16
Set equal to zero to find the x intercepts
0 = −16x^2 + 24x + 16
Factor out -8
0 = -8(2x^2 -3x-2)
Factor
0 = -8(2x +1) (x-2)
Using the zero product property
2x+1 =0 x-2 =0
x = -1/2 x=2
The x intercepts are -1/2 ,2
Since the coefficient of x^2 is negative the graph will open down and the vertex will be a maximum
The x value of the maximum is 1/2 way between the zeros
(-1/2+2) /2 = 1.5/2 =.75
To find the y value substitute into the function
f(.75) = -8(2x +1) (x-2)
=-8(2*.75+1) (.75-2)
= -8(2.5)(-1.25)
=25
The vertex is at (.75, 25)
We have the zeros, and the vertex. We know the graph is symmetrical about the vertex
Answer:
The amount <u>$20.00</u> is the overdraft fee.
Step-by-step explanation:
Given:
Katie's bank statement shows a closing balance = $178.11.
Her checkbook shows a balance = $198.11.
Now, to get what might account for the different balances?
Closing balance of Katie's bank statement = $178.11
Balance of her checkbook shows = $198.11.
As, there are no outstanding checks or deposits.
So, to get the difference of amount:
Thus, $20.00 is the overdraft amount.
Therefore, the amount $20.00 is the overdraft fee.
