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 is the direction opening of y equals -3x2 plus 6x-13?
The coefficient of x2 is -3 which is negative. Therefore the curve is downward opening.
How do you know when a fraction isn't in it's simplest form?
When you can divide the Numerator and the Denominator by something other than 1 or itself
How do you log in for the tenth time?
That depends on where you are trying to log in. Usually it is done the same way as the 9 previous times.
But if the thing you are trying to log in for the tenth time has some sort of restricted access, it might require some hacking skills or a bypass. Unfortunately I cannot help you with that, especially not knowing where you are trying to log.
Where is Roman numerals used this days?
Roman numerals can still be found on such things as... clocks and watches, sundials, old mile stones, the dates in the credits of movies, dates in books, sequals of movies (Jurassic Park III etc), the names of chemical compounds (such as Iron (II) chloride), the regnal numbers of kings and queens (Edward VI etc), and on some coins.
8x to the 6th plus 24x to the 5th plus 16x to the 4th?
8x6 + 24x5 + 16x4 = 8x4 ( x2 + 3x + 2) = 8x4 (x + 2) ( x + 1)
How do you prove that sinθ plus cosθ2 plus sinθ-cosθ2 equals 2?
Sinθ plus cosθ2 plus sinθ-cosθ2 equals 2 does not equal 2. It equals 2sinθ. The cosθ2 terms cancel out and you are left with sinθ + sinθ which is 2sinθ.
What is the nature of the solutions of the equation x2 plus 11 equals 0?
The two solutions are the conjugate complex numbers, +i*sqrt(11) and -i*sqrt(11), where i is the imaginary square root of -1.
How do you graph x plus 5y equals 55?
Massage the equation into the standard form [ y = f(x) ] so that you can read off the slope and y-intercept.
x + 5y = 55
Subtract x from each side:
5y = -x + 55
Divide each side by 5:
y = -(1/5)x + 11
Now you know that the slope of the graph is -(1/5), and the y-intercept is 11.
That should help a lot.
What is the answer to x plus 5y equals negative12?
x + 5y = -12 is not a question, and thus has no answer. This is equivalent to asking "What is the answer to yellow?"
- If you want to know the nature of the equation, it describes a line with a slope of -1/5, an x-intercept of -12/5, and a y-intercept of -12
- If you wish to solve that equation for x, the answer is x = -12 - 5y
- If you wish to solve that equation for y, the answer is y = (12 + x) / -5
- If you wish to find the rate of change of y with respect to x, the answer is -1/5
- If you wish to find the rate of change of x with respect to y, the answer is -5
- If you wish to find the indefinite integral of the function for y, the answer is -12x/5 - x2/10 + C
- If you wish to find the indefinite integral of the function for x, the answer is -12x -5y2/2 + C
What is the answer to x plus 3 equals 10?
X+3=10
X= 7
But I'm sure I understood your question incorrectly, since I don't expect someone to ask such an easy question. (No offense!)
3/10. If you multiply by 10 yo divide by 10 to maintain the consistency.
Solve this equation using subtitution x plus 2y equals 7 and 2x plus y equals 8?
x + 2y = 7
So x = 7 - 2y
Substitute this value for x in the second equation
which then is: 2(7 - 2y) + y = 8
Simplify: 14 - 4y + y = 8
-3y = -6
y = 2
Put this value of y back into the first equation:
x + 2*2 = 7
ie x + 4 = 7
x = 3
The gradient of the line y equals 4 plus 3 is?
Zero, the line is parallel to the x-axis at a distance 4+3 = 7
