1 answer:

7 0

First answer, both functions are parabolas (bowl shaped) that curve upward. The 3 makes (1/3)f(x) = g(x) the graph narrower.

36 = a(3)^2
36 = 9a
36/9 = a
4 = a

f(x) = 4x^2

Kerry purchased a used car for 14,4000. And had to pay 8% sales tax how much did she pay

saul85 [17]

Answer:

Kerry should pay = 155520

Step-by-step explanation:

Total amount paid = 14,4000 + 8% of 14,4000

It is given that,

Kerry purchased a used car for 14,4000. And had to pay 8% sales tax

To find the 8% of 14,4000

8% of 14,4000 = (8*144000)/100 = 11520

To find total amount paid

Total amount paid = 14,4000 + 8% of 14,4000

= 14,4000 + 11520 =155520

Therefore Kerry should pay = 155520
