Answer:
12750
Step-by-step explanation:
The sequence of visitors is
50, 100, 200, 400, .....
This is a geometric sequence
with common ratio r = 2
The sum to n terms is found using
= 
( a is the first term )
= 
= 50 × 255 = 12750
Answer:
A. 20,000 square feet
Step-by-step explanation:
The description is that of a rectangle 200 ft long and 100 ft wide. The area is the product of those dimensions:
area = (200 ft)(100 ft) = 20,000 ft²
Answer:
Order the numbers from least to greatest.
75, 83, 89, 94, 98, 101, 105, 108, 111, 122, 125, 130
Minimum is 75
Q1 is 91.5
The median is 103.
Q3 is 116.5
Maximum is 130
Now, look at the answer choices.
B has the incorrect median
D has incorrect Q1.
A has incorrect Q3.
C is the answer.
The point-slope equation of a line that cointains the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
so
point (-2,3) and slope -4
y-3=-4(x-(-2))
y-3=-4(x+2) is da equation
Answer:
A = $10,441.68
A = P + I where
P (principal) = $10,400.00
I (interest) = $41.68
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 0.02/100
r = 0.0002 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 10,400.00(1 + 0.0002/2)(2)(20)
A = 10,400.00(1 + 0.0001)(40)
A = $10,441.68
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $10,400.00 at a rate of 0.02% per year compounded 2 times per year over 20 years is $10,441.68.
