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.

How many roots does y equals x square-4x plus 4 have?
Have you done factoring? If you do, factor it, y = (x - a1)(x - a2)......(x - an)
n is the number of solutions and ai as i run through all natural numbers from 1 to n are the roots.
If you can't factor it, message me.
What is the equation of torqe?
The net torque is equal to moment of inertia times angular acceleration. (Στ=Ia)
How much fabric to cover 36 x 2 x 4?
You don't say what units you're using for the measurements - However, the answer is 288 units (whichever you use)
What is 2 out of 3 plus 3 out of 8?
When adding or subtracting Fractions you need "A Common Denominator (The Denominator is the bottom number and Numerator is the top) "
For example 3 and 8 are the denominators and they both go into 24, so you would do 3x8=24 and 8x3=24
Then what ever you do to the bottom you do to the top
2x8=16 and 3x3=9
The question would be 16/24 + 9/24
When adding you do not change the denominator ,but you add the numerator. The answer would be 16/24 + 9/24 = 1 and 1/24
Can you solve for a variable in an equationWhy?
YOU CAN SOLVE FOR A VARIABLE IN AN EQUATION, BUT NOT AN EXPRESSION.. FOR EXAMPLE: RIGHT WAY: 4u+6=26
-6 -6
So you are left with 4u=20
now you divide the 4u by 4 because you want to do the
opposite of multiplying. also, you divide the 20 by 4.
So... u=5
Given these kind of questions, there are often several answers, if we are allowed to freely use the four normal ways of calulating. We will focus on one answer here, however.
We have four cars; two nines and two aces. Remember that the ace card is allowed two values: 1 and 14.
We don't need to complicate matters further, though. We can give one possible answer by simply adding the two aces with the highest value (14) and subtract the two 9's:
(14 + 14)-( 9 + 9) = 10
Written out: 28 - 18 = 10
I assume the question is about cos x = -1.
While it is true that cos x is negative in both the second and third quadrants, it reaches the value of -1 where the two quadrants meet, not inside the quadrants. The point where they meet is on the [negative] horizontal axis and x is -pi radians.
What is the rise over run of y equals 2x plus 5?
Well, y= mx + b, and y is y, m is slope (aka rise over run), x is x, and b is the y-intercept (aka where the line hits the vertical axis). So is y = 2x + 5, 2 means the same thing as b, and b is rise over run. So your answer is 2. Sorry if that's really confusing. I've made it as simple as I can, but at least to me math is confusing. Best of luck!
