Several hundred years in the future, humans discover an alien world named Noveria. On Noveria, time is measured in pjokas, which is equivalent to 5.93 seconds, There are 7 pjok in every pjokas (much like there are 60 seconds in a minute). If a Noverian alien watches 40 mok of cat videos, how many minutes is this?
The population of India can be modeled by the function
P(t) = 1462(1 +0.0177)
where P(t) measures the population in millions andt represents the number of years since 2000.
1. Using this model, what was the population of India in 2009?
2. Predict the population of India in 2019.
3. If this growth rate continues, in what year will the population of India reach 2 billion people?
Hint:
How many times longer than the mean life of an extremely unstable atomic nucleus is the lifetime of a human? (Hint: The lifetime of an unstable atomic nucleus is on the order of 10s.)

- Roughly how many times longer than the mean life of an extremely unstable atomic nucleus is the lifetime of a human?arrow_forwardThe initial mass of a certain species of fish is 2 million tons. The mass of fish, if left alone, would increase at a rate proportional to the mass, with a proportionality constant of 5/yr. However, commercial fishing removes fish mass at a constant rate of 12 million tons per year. When will all the fish be gone? If the fishing rate is changed so that the mass of fish remains constant, what should that rate be? When will all the fish be gone? Inco The fish will all be gone in years. (Round to three decimal places as needed.)arrow_forwardA unit called the beard-second is the length the average beard grows in 1 second. A beard-second is defined as 10 nanometers (10 nm). The volume of the earth is approximately 259,875,159,532 cubic miles. What is this volume expressed in cubic beard-seconds? Some possibly useful conversions: 5280 feet = 1 mile, 1 quart = 0.946 liter, 2.54 cm = 1 inch, 1 week = 7 days, 12 inches = 1 foot. %3D The prefix nano means 10-9.arrow_forward

The order is for 25 mg of the medicine. The nurse walks in with a liquid and you ask to see the bottle. The bottle says 100 mg of medicine per 15 ml of liquid. How many millilitiers should she give you? Would she need to bring that to you in a dropper, a little cup, a glass or a large bottle?arrow_forwardThis year 116 kangaroos were adopted from a shelter.

From her results, she estimates that a chimpanzee from location A will have an average lifespan was 27 ± 4 years and a chimpanzee from location B will have an average lifespan was 35 ± 4 years. Part A.I: Based on the life spans (with uncertainties) above, can one argue that primates from both locations have the same lifespan? Show work to prove your point. Part A.2: Assume the researcher studied chimpanzees in Location B first. What is the percent difference in chimpanzee life span between Location A and B? You will not need uncertainties for this part. Please finish both. thanksarrow_forwardTropical rainforests covers 2% of the earth’s land surface.
