Answer:
vertex is (4,-25)
Step-by-step explanation:
To find out the vertex we use formula
From the given f(x), the value of a=1, b=-8 and c=-9
Plug in the values in the formula
x=4
Now find the value of y
plug in 4 for x in f(x)
The value of y is -25
The vertex is (4,-25)
C)5.40
The answer is $5.40 because 5 x 8=40 and the sales tax is 8% so you just add 2 decimal places so 5.00 + .40 =5.40.
P.S. You put the answer in your question.
I think the answer is C because I had da same one in I got it Righ
To find the future value the formula is
A=p e^rt
A future value?
P present value 8906.54
R interest rate 0.06
T time 9 years
E constant
A=8,906.54×e^(0.06×9)
A=15,283.68
To find the interest earned the formula is
I=A-p
I=15,283.68−8,906.54
I=6,377.14
