For 15 you divide 6 by 12 which is two so she takes 2 quizzezs a week so 2 x 3 is 6 so the other three weeks she took 6 quizzes add 12 and 6 and you get 18 :)
Plug in 4 for the value of x.
f(4)= 1/2(4)-2
f(4)= 2-2
f(4)= 0
Final answer: 0

Answer:
Step-by-step explanation:
For some growth factor f each year, the growth factor over 20 years is given as ...
f^20 = 1 +0.51 = 1.51
Then the growth factor in 10 years is ...
f^10 = (f^20)^(1/2) = √1.51 ≈ 1.22882
__
a) In the 10 years between 1998 and 2008, the price of a basic haircut would rise to ...
$18 × 1.22882 ≈ $22.12 . . . price in 2008
__
b) In the 10 years between 2003 and 2013, the price of a basic haircut would rise to ...
$19.95 × 1.22882 ≈ $24.51 . . . price in 2013
