Answer:
y = 400(1.01)^t
Step-by-step explanation:
Firstly find the rate
(Take any balance for two years, e. g 400 and 404,412.12 and 416.24,etc to get simple interest)
408.04-404= 4.04
I=(P*R*T)/100
From which R=(100*I)/PT
R= 100*4.04/404*1
R=1%
Using compound interest formula
A =P(1+r/100)^n
where n is time
substituting each value
y = 400(1+1/100)^t
y= 400(1.01)^t

Step-by-step explanation:
it has 8 subsets.
>Remember< : the number of subsets that set A have if set A has n elements
equal to 2ⁿ
In this case we A have 3 elements then its number of subsets is 2³=8

:)
(3w-8)-4(2w+3)(3w-8)-4(2w+3)
(3w-8)-(8w+12)(3w-8)-4(2w+3)
(3w-8)-(24w-96)-4(2w+3)
(3w-8)-(24w-96)-(8w+12)
(-21w-104)-(8w+12)
-29w-92
So the simplified form of this expression is -29w-92. When you look at the answer choices you have, pick the one that would make equal value with the simplified form of the one you gave here.
