Answer:
B.) f(x) = 3(4)x − 1
Step-by-step explanation:
A) f(x) = 12(4)x
B.) f(x) = 3(4)x − 1
C.) f(x) = 4(12)x
D.) f(x) = 4(3)x − 1
Given:
f(x+1) = 4f(x)
f(2)=12
f(2) = 12
f(3) = 4f(2) = 4 * 12 = 48
f(3)=48 and f(2)=12
From f(3)=48 and f(2)=12
r=48/12
=4
r=common ratio
Recall,
f(2)=12=ar
r=4
f(2)=ar=12
a*4=12
a=12/4
a=3
an=ar^(n-1)
For x term
an=3*4(x-1)
B.) f(x) = 3(4)x − 1
Answer:
TOTAL TAX IS: $19.25
TOTAL PRICE IS: $294.25
MONEY LEFT IS: $135.75
Step-by-step explanation:
First, you do a proportion:
?/275 = 7/100
the ?/275 represents how much money in $275
the 7/100 represents 7% (7 hundredths)
then you cross multiply:
275 x 7 = 1925
then you divide:
1925 divided by 100 = 19.25
<em><u>So $19.25 is the tax amount.</u></em>
<em><u></u></em>
To get the total price, you add:
Tax ($19.25) + Cost($275) = $294.25
<u><em>$294.25 is the total amount that Anna has to pay.</em></u>
<u><em></em></u>
To get what Anna has left over, you subtract:
Has($430) - Spend($294.25) = $135.75
<u><em>Anna has $135.75 left.</em></u>
<u><em></em></u>

Plug in the value of t in the function
g(30)=2/3*(30)
=2*10
=20 (answer)
