What is y cubed minus two y squared plus 4 y?
y^(3) - 2y^(2) + 4y
Factor out 'y'
Hence y(y^2 - 2y + 4)
This will not factor any further.
What are the exact solutions of x2 equals 5x plus 2?
x^(2) = 5x + 2
x^(2) - 5x - 2 = 0
This does NOT factor so apply the Quadratic Eq;n
x = { - - 5 +/- sqrt[(-5)^2 - 4(1)(-2) }} / 2(1)
x = { 5 +/- sqrt[25 + 8]} / 2
x = { 5 +/- sqrt(33)} / 2
x= { 5 +/- 5.7445... } / 2
x = 10.7445... / 2 = 5.37228....
&
x = -0.7445626... / 2 = -0.37228...
NO!!!
Sine40 = Cosine50 = 0.64278...
Sin30 = Cos 60 = 0.5
Sin 0 = Cos 90 = 0
Sin 90 = Cos 0 = 1
From Latin the word 'Sine' means 'curve'. Cosine means 'Complimentary Sine' or Complimentary curve'.
The 'awkward' decimal numbers are based on a the radius of a circle, that radius being the hypotenuse of a right- triangle based at the circles origin/centre.
y^2 + 4y + 4 = 7
Hence
y^2 + 4y -3 = 0
Apply the Quadratic Eq'n
y = { - 4 +/- sqrt[(4)^(2) - 4(1)(-3)]} / 2(1)
y = { -4 +/- sqrt[ 16 + 12]} / 2
y = { 4 +/- sqrt(28)]}/ 2
y = {4 +/- 5.2915....} /2
y = 9.2915/// / 2 = 4.64575....
&
y = -1.2915... / 2 = -0.64575....
What is the answer to a x a x a plus b x b x b equals c x c x c?
well it could be anything, but I think you are thinking of Pythagoras' theorem.
a(2) x b(2) = c(2) (2) = squared
What is x squared plus 12x plus 36 equals?
x2 + 12x + 36 = 0(x + 6) (x + 6) = 0
x+ 6=0 ;x + 6 = 0
x = -6 ; x = -6
the ratio 8:19 and the qoutient is 2 and the percent is 30
If the population of a country increases by 2.5% yearly, then that is a multiplicative factor of 1.025. Between 1960 and 2000, there are 40 years, so raise that factor to the power to 40, 1.02540, and you get 2.685. If the starting population in 1960 were 25 million, then, with a population growth of 2.5% per year, the population in 2000 would be 2.5 million times 2.685, or 6.7 million.
There are 24 hours in a day and 60 minutes in an hour. So,
24 * 60 = 1440 minutes in a day
================================================you can figure out othe month lengths yourself now
x0.5 is the same as x1/2
Any number or variable to a fraction power can be written as a form of a radical.
In this case it would be written as √(x)
To actually solve you would need to know what x is.
What are tha elements of science?
There are 92 elements that naturally occur and several others that are man made. Things like gold, silver, oxygen, hydrogen, mercury. Look at the periodic table of elements. That will show you all of them.
Sounds like you're referring to the chemical elements. These elements are the most basic categories of matter. They include Oxygen, Hydrogen, Silicon, Gold, Silver, Carbon, Uranium, etc. Most matter we found in nature is a combination of these elements. For example, steel is a combination of Carbon and Oxygen. Sand is a combination of Silicon and Oxygen. Water is a combination of Hydrogen and Oxygen.
See an introductory Chemistry textbook for more.
What percentage of high school teach Latin?
In Britain, around 60% of independent schools and 15% of state schools offer lessons in Classics, including Latin.
In 2008:
- over 130,000 students in the US took the National Latin Exam.
- around 3 dozen schools in New York City taught Latin
In 2009, 7 schools in Washington State offered Latin.
What is x in x3 equals 5.231010?
x^(3) = 5.1231010
Take the cube root
Hence
x = 5.231010^(1/3)
x = 1.735915243
Pre-calculus honors covers more advanced topics than algebra 2, such as trigonometry and limits. To prepare, focus on strengthening your algebra skills, particularly with functions, graphs, and equations. Additionally, familiarize yourself with trigonometric functions and properties to ease the transition.
Where did Ada lovelace do most of her work at?
Ada had no job, after her father died when she was nine years of age, her mother tried to force her into slavery. Ada fought it for quite a while, until there was no use. Her aunt from her fathers side, took her and turned her into a slave, used to fix other computers, with that and the knowledge she had with math, she learned how to make a program for her computer. As soon as she made one, she fled the country to become famous. And died at the age of 36, because she had a bad case of measles. :) Your welcome!
Calculus, like any math, is best learned by practice. You can use a Study Deck - see the link to learn how to make and use one! - for the formulae and definitions, but the key to learning is to work problems until you really understand it.
To find the area of the Norman window, you need to divide the perimeter by 2 to get the width of the rectangle, which is 22.5 feet. The radius of the semicircle is half of the rectangle's width, so it's 11.25 feet. The area of the rectangle is 11.25 * 22.5 = 253.13 square feet, and the area of the semicircle is 0.5 * pi * 11.25^2 = 198.93 square feet. So, the total area of the window is 253.13 + 198.93 = 452.06 square feet.
Is a piecewise graph a function?
Yes, a piecewise graph can represent a function as long as each piece of the graph passes the vertical line test, meaning that each vertical line intersects the graph at most once. This ensures that each input has exactly one output value.
Explain how to do the basic math to determe 3.14 x diameter 2squared?
Your question doesn't make sense. The area of a circle is Pi (approximately 3.14) times the RADIUS squared. An example would be a circle with a diameter of 6 inches and thus the circle would have a radius of 3 inches. Three squared (3 times 3) is 9, and 9 times Pi is approximately 28.3 square inches.
Who are the most tested students in the world?
There is no concept of 'most tested students'. This is a misnomer.
Yes, all over the world, the student community is tested on their learning and experieinces. Some topics may need direct testing and some indirect testing. The two types of evaluation- formative and summative come into the picture here.
How long would it take to count a million?
Naturally, it depends on how fast you count.
If you count 1 every second and you don't take any breaks,
it would take you
11days 13hours46minutes 40seconds
to reach 1 million.
Example of exponential function?
Any function of the form aebx - for non-zero a and b - is exponential. For examples, just replace "a" and "b" with any non-zero number.
Equivalently, any function of the form cdx - once again, for non-zero c and d - is exponential. Here, too, you can replace c and d with any number to get examples.
