3. A biologist is studying the growth of bacteria cells in a culture. She begins with 10 cells of bacteria in a nutrition-rich environment. For the first 24 hours of the study, the cells double in population every hour. The biologist writes the following equation to describe this population growth: y = 10 * 2t Where t is the number of hours since the study began, and y is the number of bacteria cells. a. How many bacteria are in the culture after 5 hours? b. At what time will there be 81,920 cells in the culture?

In 2004 it surfaced in Reader's Digest presented as having happened to a teacher at an unnamed community college. Four students walked in halfway through American history test my father was giving at the local community college. "Sorry," they said, "we had a flat tire." An understanding man, Dad said that if they could answer just one question correctly, he would give them each an "A" for the exam. The students agreed. So my father handed each one a piece of paper, placed them in four separate comers and said, "Write down which tire was flat." Kurt Smith What is the probability that these four students would give identical answers if they hadn't had a flat tire? Why?

The answer is not clear enough, please write in a way that can be read because I only have one try to submit.

3. Which of the following is the location of an asymptote in the graph y = csc x? 37 X = 2 Ox-- X = 2 2 x = 0

I can't tell what the answer is supposed to be. None of the answers are the same as the options and the answer is option -g  There is no g. Can you please clear up the answer by writing it legibly.

A test contains 12 problems. The teacher gives 24 points for each correctly solved problem and withdraws 15 points for incorrectly solved problems. If a problem is not solved it is considered incorrect.   Ron claims he got a zero for the test. That is impossible says Mia. Is there any reason for mia to say that?

That is the first answer I got and it was also marked as incorrect. I am not sure why. I also tried the rounded version and it didn't work.

Dr. Volz gave an exam with 14 questions, but students only had to answer 10 of them. Suppose the exam instructions say that either BOTH questions 1 and 2 may be included among the ten OR NEITHER is to be included.  How many different choices of 10 questions are there?
