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.

Is 4.8 x 6.2 greater than 10 and less than 20?
4.8 x 6.2 = 29.76
The product is greater than 10, but not less than 20. So, the answer is no because the statement has the word 'and' in it which means both conditions must be true.
One condition is true: 29.76 is greater 10; other is false: 29.76 is less than 20.
What is the function of x and y?
The function of X is verticity (up and down). The function of Y is horizontal (left and right).
no because if you dont have a number after the X, it wont equal anything.
How do you graph the function y equals 2x minus 3?
-- Set 'y' equal to zero, find 'x', and make a dot at that point on the x-axis. (x = 1.5)
-- Set 'x' equal to zero, find 'y', and make a dot at that point on the y-axis. (y = -3)
-- Lay your ruler along the two points and draw the line.
What is the indefinite integral of 3sinx 5cosx?
With respect to x, this integral is (-15/2) cos2x + C.
The Bernoulli equation was formulated by Daniel Bernoulli who was a Swiss mathematician. The Bernoulli equation is basically a statement of the conservation of energy in fluid dynamics.
What are the steps to solving a proportion?
Confused? Don't be!!! Proprotions are easy once you understand them. :) Let's take a math problem:
A baby giraffe casts a 3.2-foot shadow and an adult giraffe casts a 8-foot shadow. The adult is 15 feet tall.
The easiest way is to think this: Put the shadow heights over the height of the giraffe. So the proportion is:
3.2/x = 8/15 Cross multiply. (3.2 x 15) equals 48. (8 x (x) ) equals 8x.
48 divided by 8 equals 6. 6 is the answer!!! :) now u are set for solving

What is 5x -9 when x equals 4?
5x-9
Substitute 4 in for x
5(4)-9=
Solve.
9-9=0
the answer is zero.
The answer is not zero you added when you were supposed to multiply so the real answer is 11.
Can you solve an variable in an equation?
You may want to be a little more specific about what your question is asking.......
you can solve a variable in an equation or expression. For example: 1+2=y
just remember, you arnt necessarily "solving" a variable, but I guess you could say that considering a variable can change continuously. Be sure to consider that if you do "solve" a variable you end up with a constant ( a never-changing number) therefore, it is no longer a variable, but just an answer.
Hope that helped! :-)
What is the answer to 2x - 3 equals 10x - 99?
2x-3 = 10x-99
start by moving the terms with variables (x) on one side of the equal sign, and the constants (regular number, with no variables) to the other side. Do this by addition and subtraction.
2x-3 = 10x-99
+99 +99
now you have
2x +96= 10x
now get both of the variables on the right side
2x+96 = 10x
-2x -2x
now you have
96 = 8x
now solve for x by dividing each side by 8
96/8 = 8x/8
x= 12
What is the form for y equals mx plus b?
y=mx+b
is commonly referred to as slope-intercept form. It is one way to show a linear equation, where:
y = the y part of an ordered pair,
x = the x part of an ordered pair,
m= the slope of a line-rise over run is slope, so your numerator is how many you go up, and your denominator is how many you go over-you draw these dots and then connect them, and
b = the y intercept-that is, the ordered pair where the line crosses over the y axis.
