Answer: 511

Step-by-step explanation:

53.

For this problem simply plug in the numbers: 1 through 9 for n

the n=1 on the bottom represents the start and the 9 at the top represents the end

and the 2^n-1 represents the rule

solving for a1: plugging in one for n

a1=2^1-1

a1=1

a2=2^2-1

a2=2

a3=2^3-1

a3=4

a4=2^4-1

a4=8

a5=2^5-1

a5=16

a6=2^6-1

a6=32

a7=2^7-1

a7=64

a8=2^8-1

a8=128

a9=2^9-1

a9=256

after finding all these values add them all together and you should get your answer

1+2+4+8+16+32+64+128+256

=511

To save money, you put $200 in your bank account each week. After saving for 4 weeks, you have $1,700$ dollars in your account.
kozerog [31]
Let's say the savings in your account are given by $V, the number of weeks by n and the starting balance by $x:
V = x + 200n

Now if after saving for 4 weeks you have $1700 in your account, then:
1700 = x + 200*4
1700 = x + 800
x = 900, thus your starting balance is $900

Using this information we can now write up the general equation for the savings at the end of each week:
V = 900 + 200n

Which one of these equations match the graph?
beks73 [17]

Answer:

C   y = 2sin(1/3) x

Step-by-step explanation:

It's a sin function since y = 0 at x = 0

The amplitude is 2

There are 2 cycles in 12π

so the period is 6π

The x coefficent is then 2π/6π  = 1/3

Answer

C   y = 2sin(1/3) x
