Calculus
The branch of mathematics that deals with the study of continuously changing quantities, with the use of limits and the differentiation and integration of functions of one or more variables, is called Calculus. Calculus analyzes aspects of change in processes or systems that can be modeled by functions. The English physicist, Isaac Newton, and the German mathematician, G. W. Leibniz, working independently, developed calculus during the 17th century.

What are 5 different values of x?
In algebra, x can have any value as the letter is used to represent any number that is unknown until solved.
e.g. 2x=4
x=2
In Roman Numerals, X is 10.
What does y equal in this equation y equals 2x plus 4?
As the equation plainly tells us, "Wye is equal to two eks plus four".
The value of 'y' completely depends on the value of 'x'. Whenever 'x' changes,
the value of (2x + 4) changes instantly.
Is one point one times ten to the two hundred thirteenth a scientific notation?
Yes. It is scientific notation. If written in standard form it would have an 11 followed by 212 zeros.

There is no visible operator between 2x and 4y in the second equation.
y = -4x is a line with a slop of -4 and a y-intercept of 0 (it passes through the point (0,0).
What is 8x-23 equals 3x plus 2?
8x - 23= 3x + 2
+23 +23
8x=3x + 25
-3x -3x
5x=25
x=5
the answer is X=5
How do you solve x plus 1 equals x plus 2?
The answer would be no solution. x+1=x+2. Subtract 1 from both sides x=x+1. Subtract x from both sides. 1 does not = 0
What is 5 divided by 6x minus 1 divided by 2 equals 7?
Unfortunately we don't know if you mean 5/(6x) -1/2 , or ((5/6) times(x-1) )/2 or any one of several other interpretations of the question.
Can cubic functions have more then one form?
Not in a mathematically significant way. That is, any one should be easily converted to another.
How do you times 2 didit numbers in your head?
You don't really times two numbers, you can however find the product of two numbers. Anyways, there are a number of tricks, but the easiest way is to break the number into easier pieces:
For example:
60 x 90 = (10 x 10) x (6 x 9) = 100 x 54 = 5400
We split the 10's out, because 10 x 10 is easy. And 6 x 9 is also easy.
60 x 12 = (6 x 10) x (4 x 3) = (2 x 3 x 10) x (2 x 2 x 3) = (2x2x2) x (3x3) x 10
=8 x 9 x 10 = 72 x 10 = 720
As you can see on this one, you had to keep breaking the numbers apart to find an easier combination, but ultimately it pans out. The problem is each time you break a number into more numbers, you are more prone to making a mistake trying to keep track of all the numbers.
Also, this method doesn't always work well, but it can still bemanageable:
11 x 12 = 11 x 4 x 3 = 44 x 3 or 33 x 4
You have to carry a digit now, and that's slightly harder to do. But you can still do it in your head. "4x3=12, carry the 1, 4x3=12+1 = 13, the answer is 132."
Sometimes though, it will be nearly impossible using this method:
33 x 77 = 3 x 11 x 7 x 11 = 21 x 112 = ???
Another method to make problems a little easier:
You can reduce a number by one factor:
33 x 7 = 11 x 3 x 7 = 10(21) + (21) = 210 + 21 = 231
If 3x7=21 is the factor, I basically extracted one factor to make the problem 10(21) and then just added that extracted factor back in. This takes a little longer to grasp than the above method.
Would it be ok to put 235 40R18 on a 2004 jaguar x-type instead of the standard which is 225 40R18?
The 235 will be slightly wider than the 225, as long as your tires do not rub when turned from stop to stop it is a good swap.
How do you factor the expression x cubed minus 5x plus 4?
By inspection, the sum of the coefficients is 1 - 5 + 4 = 0Therefore x = 1 is a root. That is (x - 1) is a factor.
Then suppose the other factor is ax^2 + bx + c
SInce the coefficient of x^3 is 1, then a = 1 so that the second factor is x^2 + bx + c
Therefore (x - 1)*(x^2 + bx + c) = x^3 - 5x + 4
x^3 - x^2 + bx^2 - bx + cx - c = x^3 - 5x + 4
Comparing coefficient of x^2 gives -1 + b = 0 so that b = 1
Comparing coefficient of x gives -b + c = -5 so that c = b - 5 = -4
Comparing constant terms gives -c = 4 or c = -4 which confirms above calculations.
Thus, the second factor is (x^2 + x - 4) which does not have rational factors.
What is the least common multiple for 48 and 70?
Taking each number in turn we factor it into primes :- 1) 48 = 2 * 2 * 2 * 2 * 3 = 2 ^4 * 3 ^1 2) 70 = 2 * 5 * 7 = 2 ^1 * 5 ^1 * 7^1 For each prime factor we take the one with the largest number as the index, eg for the factor 2 , we have 4 and 1. The largest is 4 and so on for each prime factor that occurs and then multiply them together so we have all together 2 ^4 * 3 ^1 * 5^1 * 7^1 = 16*3*5*7 = 1680 which is the Lowest Common Multiple of 48 and 70.
There are many different kinds of analyses within mathematics.
How many centimeters are there in 300 millimetres?
There are 10 millimetres in one centimetre. Therefore, 300 millimetres is equal to 300 / 10 = 30 centimetres.
30 cm
