9
Step-by-step explanation:
according to the question
27×⅓

Joan makes $275/week.
In addition to $275, she also makes 4 percent on sales over $1000.
So, 1250 - 1000 = 250.
Then 250(0.04) = 10.
Let t = amount of her paycheck for the week.
t = $275 + $10
t = $285
128
This question requires us to solve an infinite GP
As we can see the first unit is 16 wide, then 8, then 4 and so on; this can be written as
∞
(64 used as 16*4 = 64 is the area of the first rectangle)
We have 
∞
where a is the first term and r is the common ratio of the GP for summing an infinite GP.
here we have
Therefore
∞

Point B is located at (4, -2)
An=a1+d(n-1)
a1=first term
an=nth term
d=common dffernce
given
first term is -5
it increases by 1
an=-5+1(n-1)
a10
a10=-5+1(10-1)
a10=-5+1(9)
a10=-5+9
a10=4
10th term or a10 is 4
