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.

Are the fractions 43 and 21 equal or not equal?
well, if you mean 43/100 and 21/100, no. because obviously neither can be simplified any more. I am guessing you didnt mean hundredths. sorry
Phi is, above all things, the 21st letter in the Greek alphabet, so it's hard to say who created it. However, the number commonly attached to it, the golden ratio, has a long history, starting with the mathematicians of Ancient Greece, and has been studied, used, and approximated ever since. Just a few of the mathematicians who studied Phi are Euclid, who gave the earliest known definition of the golden ratio; Kepler, who described it as one of the two greatest feats of mathematics (along with the Pythagorean Theorem); Michael Maestin, who was among the first to give a rough approximation of the golden ratio's value; and Mark Barr, who first used the letter Phi to describe the ratio.
So, I guess in the end the creation of Phi was sort of a group effort.
How do you factor x³ plus 5x² plus 6x?
(x3+5x2+6x)/x to get x(x2+5x+6)
find numbers that multiply to 6 and add to five (2 and 3)
your factors are x, x+2, and x+3
Is y equals 2x 5 a Linear equation?
It is not possible to answer the question due to deficiencies in the browser used by WA for posting question. We cannot see most symbols. Please resubmit using words such as "plus", "minus", "equals".
-15 = 3 + 3x is an equation in one variable, x, which can be easily solved, by simple algebraic manipulation...
-15 = 3 + 3x
-18 = 3x {subtract 3}
-6 = x {divide by 3}
... so, x = -6.
Which of these equations is a direct variation y equals -8x plus 1?
There is only one equation that is given in the question and that equation is not a direct variation.
if you mean to plot it on a graph like this:
y = 4x2
Then yes. It opens upward away from the x-axis, with it's focal point at (0, 0)
No, the Roman numeral for 5 is V.
X is the Roman numeral for 10.
What does x equal when -38-10x equals 9x plus 19?
-38-10x = 9x+19
-38-19 = 9x+10x
-57 = 19x |: 19
-3 = x
Therefore x equals -3
4x plus 1 equals 52x how do you solve this?
Subtract 4x from each side getting 1 = 48x so x = one forty-eighth
In the equation 2 plus 34 what should be done first?
There is only one thing to do in this equation; add 2 to 34
Evaluate 132ft s x 1mi 5250 x 3600 s h?
First, multiply all the top numbers together:
132ft * 1mi * 3600s = 475200 ft*mi*s
And put that over top of all the bottom numbers multiplied together:
1s * 5280ft * 1h = 5280 s*ft*h
By dividing the numbers together, we get:
475200 / 5280 = 90
Now we have to divide the units:
(ft*mi*s) / (s*ft*h) = mi/h
So your answer is 90 miles per hour.
