I added this video because, as John says, students will get the wrong answer. I did.
A quadratic equation has four parts. Count them. The 16th letter pi—which is written as the Greek letter for p, or π—is the ratio of the circumference of any circle to the diameter of that circle. Regardless of the circle’s size, this ratio will always equal pi. Ratio...picture a fraction.
Tourbillon
Part of speech noun; origin French, 15th century; definition 1. Any part of a machine with a spiral movement, or 2. A whirlwind. Turbine Part of speech noun; origin French, attested 1838; definition “waterwheel driven by the impact or reaction of a flowing stream of water.” Turbō Part of speech noun; origin Latin; definition “spinning top, eddy, whirlwind, that which whirls.” Originally applied to a wheel spinning on a vertical axis driven by falling water, later of mechanisms driven by the flow of air, and still later, “turbo” in reference to gas turbine engines is attested from 1904. There’s the Fibonacci spiral again. Noun zephirum
Leonardo is famous for the Fibonacci Sequence, which is pictured in geometric form above and in arithmetic form below. 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55 … The next number is found by adding up the two numbers before it. Word Sense Dictionary, Math is Fun, Wikipedia, and Quora helped me affix Latin to English to math, my favorite subjects. What comes next is unbelievable. Add asongscout of YouTube and Patreon.
This method is good for those nasty national exams of about one minute per question, the section without a calculator. “Because there are 12 reports to compile each month, the total number of reports in a year is the zenzic of 12.” The square root of 144 is a perfect square, thus no need for the shortcut.
Seeing the flower, missionaries took heart. It reminded them of Christ’s Passion and the compelling reason they were toiling about looking for souls in moist jungles. This is what they saw in the physical aspects of flower and plant:
Purple: the color of penance and sacrifice Five sepals and five petals: the ten Apostles who neither betrayed Our Lord like Judas nor publicly denied Him like Peter (note that the missionaries weren’t trying to slur Peter—who, unlike Judas, repented and became a great saint!) Three stigma: the nails piercing Jesus’ hands and feet Five anthers: His five wounds Circlet of corona filaments: the crown of the thorns Three-pointed leaves: the Holy Trinity Vine: God’s attachment to the earth The missionaries used the flower to teach people about the Passion. They sent descriptions of this miraculous plant back home. The Spanish people came to know it as, “The Flower of the Five Wounds.” Since then, the flower’s name in almost every language has reflected its beautiful representation of the Passion.

College founded in 1917 by the Dominicans (Aquinas was a Dominican) Engineering-Physics Faculty, Areas of Expertise: Theoretical Particle Physics (Particle Colliders); Philosophy of Science/Philosophy of Nature; Relationship between Faith and Science Mach 1 = 767.269 mph/767.269 mph. The Mach number is the ratio of the speed of the aircraft to the speed of sound. Any number over itself is equal to one.
An airplane flying at less than Mach 1 is traveling at subsonic speeds; at about Mach 1, or transonic, it is at the speed of sound; and greater than Mach 1 is supersonic. The root of the English word is sonus [Latin for sound]. The prefixes are sub [under], trans [across], and super [beyond]. What is the origin of the term conservative?
Conservatism is a political position that emphasizes tradition and relies primarily on the individual to maintain society. The term was first used by François-René de Chateaubriand in 1818 during the Bourbon Restoration. Conservatives sought to reverse the policies of the French Revolution. The Latin word for conservative is optimatium, from optimum, incomparable, the best or most advantageous, surpassing all others. synonyms: best, ideal, optimal Click on ideal and you will be taken to math concepts by Wiktionary. Math builds. One concept rests upon the previous. Not so for grammar. Once you have learned grammar, and you can learn it in a year, there is nothing more. I lie. I look at my grammar book frequently, but that is different, for my mind is a sieve. I subscribe to TabletClass.

What are the next three letters in this combination? OTTFFSS
Choose one OTT TEN ENT FFS Answer ENT eight nine ten Riffraff – The Mississippi River was the main thoroughfare from north to south. Riverboats carried passengers and cargo, but they were expensive, so most people used rafts. Everything had the right of way over rafts, which were considered cheap. The steering oar was called a “riff”, which transposed into “riffraff.”
Showboat – This was a floating theater built on a barge that was pushed down the Mississippi. The boat did not have an engine, and the boat was gaudy and attracted attention, which is why we say that someone who is the life of the party is “showboating.” Barge in – Heavy freight was moved along the Mississippi in large barges pushed by steamboats. The barges were hard to control and would sometimes swing into piers or other boats. People would say, “They barged in.” Shot of whiskey – In the old west a .45 cartridge for a six-gun cost 12 cents, and so did a glass of whiskey. If a cowhand was low on cash, he would often give a bartender a .45 cartridge for a drink. This became known as a “shot of whiskey.” Math trivia – No piece of paper can be folded in half more than seven times. Alexander, nine, and I discussed parallax. I thought that parallax was in a stealth fighter jet, but no. Parallax has to do with our perception of a distant object, such as a jet. Try this. Put your finger in front of you and look at an object. I chose a picture on the wall. I closed my left eye and then my right eye, and the finger moved to the right when I closed my right eye. We said we would teach each other about parallax. using the sexagesimal system, not the decimal system
The tools needed are a protractor, compass, and ruler; a mini drafter is recommended. Alternate meaning of involute - involved or intricate. “From the second chapter to the end, the detective novel grew more and more involute.”
“In 1969, NASA’s Apollo missions installed reflective panels on the moon. These have shown that the moon is currently moving 3.8 cm away from the Earth every year.” The USA is one of the few countries still using the Imperial system of measurement, where things are measured in feet, inches, pounds, ounces, and so forth. Divide the length value by 2.54. Thus, 3.8/2.54 = 1.49606299. Round up to a tenth, which is 1.5, or 1 ½ inches. https://www.space.com/moon-drifting-away-from-earth-2-5-billion-years
I forgot what a logarithm is, so I checked. A logarithm is the power to which a number must be raised to get some other number. For example, the logarithm of 100 is two, because 10 to the power of two is 100. Thus, written mathematically, log 100 = 2. That's all.
Bees make hexagonal cells. A hexagon has six sides, six edges, and six vertices. The sum of the interior angles is 720 degrees (6 x 120). A hexagon has nine diagonals. The formula for the number of diagonals is n(n-3)/2, where n represents a side. If there are six sides, by using the formula, we determine that there are nine diagonals: 6(6-3)/2 = 9. image above courtesy of study.com
Fr. Pierre Jacobs, S.J., taught me geometry in 10th grade. Observed bee geometry arises only if cells are previously arranged in a way that each one is surrounded by six other similar cells. We had a hiccup in our parish bulletin on Sunday. It read Sexuagesima Sunday II. That should be Sexagesima. The Latin word for six is sex, and 60 is sexaginta. Sexagesimal, also known as base 60 or sexagenary, is a numeral system with sixty as its base. It originated with the ancient Sumerians in the 3rd millennium BC, was passed down to the ancient Babylonians, and is still used—in a modified form—for measuring time, angles, and geographic coordinates. An analog clock has three hands. The short hand indicates the hour, the long hand indicates the minute of the current hour, and the thinnest hand indicates the second of the current minute. I have one in the house that runs on a battery in case there is a blackout. Because of digitalization, young students today struggle with this concept.
Once you have had some trigonometry, you can find azimuth. Though spaceship instruments automatically calculate azimuth, space explorers must understand what it means. The cosine function in a triangle is the ratio of the length of the adjacent side to the length of the hypotenuse. The cosine function is one of the three main trigonometric functions, and it is itself the complement of sine (co + sine). About 500 glaciers out of 200,000 have disappeared in the last 50 years.
500/200,00 = .0025 .0025 X 100 = 0.25% 0.25% = 1/4 of 1% Memorize your times tables up to 20. Solutions come faster. Gotcha! You can't shortcut the solution by subtracting the exponents, as in exponent 20 minus exponent 2 (4 being 2 squared). Subtracting the bases results in zero. Don't go there.
One could have guessed two and been right, but this solution is more like a proof demonstrating the use of the quadratic equation, root quattuor, Latin for four because there are four terms, including the zero. I have a friend whose last name is Ekk. If one saw his family approaching, one could say, “Here come the Ekks.” X
The square root of -9 is 3i. What is i? It is an imaginary number. The answer has to do with complex numbers, not just with the real numbers on the number line.
