Credit sales are collected as follows:65 percent in the month of the sale.25 percent in the month after the sale.10 percent in t

Vitek1552 [10]

Answer:

Step-by-step explanation:

a) November sales = (Total Uncollected Sales - Uncollected Sales from December) / Collection rate after two months

= ($121,100 - $87,300) / 0.20

November sales = $169, 000.00

b) December sales = Uncollected sales from December / Collection rate of the previous month sales,

Therefore: December sales = $87,300 / 0.45 = $194,000

December sales = $194,000.00

c) Each month's collection for the company are:

Collections for ech month = 0.20(Sales from 2 months ago) + 0.25(Last month's sales) + 0.55 (Current sales)

January collections = 0.20($169000.00) + 0.25($194,000.00) + 0.55($132,000)

January collections = $154,900.00

February collections = 0.20($194,000.00) + 0.25($132,000) + 0.55($149,000)

February collections = $153,750.00

March collections = 0.20($132,000) + 0.25($149,000) + 0.55($164,000)

March collections = $153,850.00

The diameter of a bacteria colony that doubles every hour is represented by the graph below. What is the diameter of the bacteri

vlada-n [284]

Option B: 256 is the diameter of the bacteria after 8 hours.

Explanation:

From the given, it is obvious that the graph is an exponential function.

The general formula is given by,

$y=a(b)^x$

Where a is the initial population,

b is the growth rate and

x is the number of hours.

It is given that the diameter of the bacteria doubles every hour.

Then, we have,

$b=2$

Let us substitute the coordinate (0,1) and $b=2$ , we get,

$1=a(2)^0$

$1=a$

Thus, substituting $a=1$ and $b=2$ in the general formula $y=a(b)^x$ , we have,

$y=1(2)^x$

We need to determine the diameter of the bacteria after 8 hours.

Let us substitute x = 8 in the equation $y=1(2)^x$ , we get,

$y=1(2)^8$

$y=1(256)$

$y=256$

Thus, the diameter of the bacteria after 8 hours is 256

Hence, Option B is the correct answer.

On a graph where the y-axis and x-axis jump from 1 to 10 to 100, with approximately equal space between 1-10 and 10-100. Which o

otez555 [7]

Answer:

d-all of these options are valid interpretations of this graph

Step-by-step explanation:

Logarithmic scales are not linear, and they are used for large range of possitive numbers. The value represented by each equidistant mark on the scale is the value at the previous mark multiplied by a constant, in this case 10.

So, in large islands, large incresaes have a small effect ( the distance is the same from islands thas has 100 to 90 square miles, than for 2 islands measuring 10 to 9).
