75 million people died in World War 2 spread over 6 years. Right now in the World 13 000 people have died due to the pandemic. If the doubling time is 5 days (many people think it will decrease to 3 days) how long before the death toll will be greater than World War 2?

There are 2 different catalogs sent to customers. One of the catalogs costs 50 cents to make and is 50 pages long. The conversion rate for the catalog is 5% and each customer brings in 315 dollars. The second catalog costs 95 cents to make, is 100 pages long and each customer brings in 300 dollars from it. The profit margin is 30%. What should the conversion rate for the second catalog be to make at least the same amount of profit as the first one.

I am submitting this for the second time, because the person that answered the first time definitely did not read my last two paragraphs. I need to DISCUSS, why the theorem works when adding a point D. I cannot draw a triangle and throw point D on it. I understand up to a certain point, but I have no idea what my professor is looking for in my answer. I have included her comments to hopefully help you help me. Thank you.

My question is based on the following:

Consider the axiomatic system and theorem below:

Axiom 1: If there is a pair of points, then they are on a line together.

Axiom 2: If there is a line, then there must be at least two points on it.

Axiom 3: There exist at least three distinct points.

Axiom 4: If there is a line, then not all of the points can be on it,

Theorem 1: Each point is on at least two distinct lines.

I have proven and understand up to 3 points, but I am struggling with explaining what happens with the 4th point.

If I use Axiom 3 to create 4th point D (the first 3 being A, B, and C), this will give me distinct lines AD, BD, CD, ADB, ADC, and BDC.

ADB, ADC, and BDC were all previously existing lines, and AD, BD, and CD are new lines, correct?

These are two separate cases because I cannot have point D on a previously existing line, and a new line, at the same time. I feel I understand up to this point. I need to discuss these two possibilities separately, but I am confused on how to go about that.

My professor states that I need to "discuss the different possibilities for how many distinct lines those are, we do not know if those are 3 distinct lines or not, this is where the different cases come in". I don't understand AT ALL what she is looking for.

A company produces individual resistors and transistors as well as computer chips. Each set of resistors requires 2 units of copper, 2 units of zinc, and 1 unit of glass to manufacture. Each set of transistors requires 3 units of copper, 3 units of zinc and 2 units of glass. Each set of computer chips requires 2 units of copper, 1 unit of zinc, and 3 units of glass. If there are 150 units of copper, 110 units of zinc, and 160 units of glass available, how many sets of resistors, transistors, and computer chips should the company manufacture to use all of its available supplies or raw materials? how many resistors, transistors and computer chips?

Holly Krech is planning for her retirement, so she is setting up a payout annuity with her bank. She wishes to receive a payout of $1,700 per month for twenty years. (Round your answers to the nearest cent.)

(b) How large a monthly payment must she make if she sets the ordinary annuity up twenty years before her retirement? $

Use a software program or a graphing utility to solve the system of linear equations. (If there is no solution, enter NO SOLUTION. If the system has an infinite number of solutions, set x5 = t and solve for x1, x2, x3, and x4 in terms of t.) x1 − x2 + 2x3 + 2x4 + 6x5 = 16 3x1 − 2x2 + 4x3 + 4x4 + 12x5 = 33 x2 − x3 − x4 − 3x5 = −9 2x1 − 2x2 + 4x3 + 5x4 + 15x5 = 34 2x1 − 2x2 + 4x3 + 4x4 + 13x5 = 34 (x1, x2, x3, x4, x5) =

After a weekend of lucrative gigs, a singer finds herself with an extra $ 1,500. She currently has $4350 of credit card debt, on which she is charged an annual yield of 24%. Putting $1,500 toward this would cut that debt to $1,850. Calculate the annual rate of return if she does this. Round, if necessary, to the nearest 0.1%.
