f(n) = 5.77(0.98ⁿ)

The function above can be used to estimate the number of farms, f(n), in millions, in the United States for 0 ≤ n ≤ 72, where n is the number of years after 1940.

We began an ambitious program at visible and near-infrared wavelengths as a natural successor to HUDF: the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS), 30 pronounced "candles." We designed CANDELS primarily to document the first one-third of galaxy evolution. The program also would enable astronomers to search for the most distant Type Ia supernovae— exploding white dwarf stars that are the 35 best-known standard candles for measuring the universe's recent expansion rate. CANDELS could thus test whether Type la supernovae are also a valid yardstick for the early universe.

The answer is 8x = -16. The steps to simplify are below.

10 = 2x + 14 -4 = 2x -2 = x

Once solving for x, check the answer choices for one that is true given the value of x.

4x = 8 -> 4(-2) = -8 -> incorrect 10x = 16 -> 10(-2) = -20 -> incorrect 8x = -16 -> 8(-2) = -16 -> correct 12x = -144 -> 12(-2) = -24 -> incorrect

The answer is no change. The SAT will never ask you to choose between using and excluding an Oxford comma (nice!).

The second option includes an extraneous comma; you don't want to include a comma after the conjunction, but before the final list term. The third option is unnecessarily verbose. The last option uses a semicolon where you shouldn't use one, as it's not dividing two otherwise-complete independent clauses.

A recent paper published by the Trust for Public Land notes that parks are a boon to communities in terms of both health and social development. Exercise, play, and exposure to green space have all been linked to improved health. The report also notes that community spaces, such as gardens and sports fields, are linked to reduced crime and a stronger bond among neighborhood residents.

The answer is .6. For any value x, it holds that sin(x) = cos(90º - x). This means that, in a right triangle, the sine of one acute angle will always equal the cosine of the other acute angle.

Land formerly used for garbage is usually inexpensive to buy. It is also prolific: the Environmental Protection Agency estimates that the United States has at least 10,000 closed municipal landfills. By restoring the landscape, these parks also hold tremendous benefits for the environment; because they transform a blemish into an attractive asset, they have the added benefit of raising property values.

When Arthur Conan Doyle introduced the brilliant and eccentric London detective Sherlock Holmes in the 1887 novel A Study in Scarlet, relatively few readers took notice. Beginning in 1891, though, a steady stream of short stories published in the London magazine The Strand caused Holmes's fan base to grow exponentially, and by 1893, the character was an international sensation. With Holmes at the height of his popularity, readers who purchased The Strand's December 1893 issue were taken aback by the shocking conclusion of the latest installment: Holmes, having plunged from a waterfall in Switzerland while fighting his enemy Moriarty, was dead.

Having introduced Moriarty in the same story, Conan Doyle in fact had long desired to end the series. "I am weary of his name," the author declared: devising the intricate plots of the stories took a great deal of time and effort, and Conan Doyle wanted to dedicate his energies elsewhere. Believing the Holmes stories to be lowbrow work, he wanted to focus on writing historical epics instead. Lucrative publishing contracts had made it difficult to walk away from the series, but by 1893 the author had made up his mind. "If I had not killed him, he would certainly have killed me," Conan Doyle remarked ominously.

Built in southern Greece in the fourth century BCE and rediscovered in the late nineteenth century CE, the outdoor amphitheater of Epidaurus is renowned for allowing performers' voices to carry even to the last of its fifty-five rows. The source of this acoustic quality, therefore, has long been misunderstood.

Welcome to SAT-a-day!

I'm MJ (@catstrophysics)! This blog is a result of my side gig as a standardized test/physics tutor, and I thought it would be fun to post SAT multiple choice questions as polls on here to sate the Tumblr user desire to click buttons.

Each question will be open for 3 days, after which I'll reblog with the correct answer and a brief explanation of how to do it/any tips and tricks.

If you're a high school student looking for an actual SAT/ACT/physics tutor, please feel free to DM me, and I'd love to work with you!
