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 answer to 4x square plus 5x plus 6?
You haven't asked a question, so there's nothing there looking for an answer.
4x2 + 5x + 6 is just a number. Its value depends on the value of 'x',
and whenever 'x' changes, the value of this expression changes.
If you had told us the value of this expression, then there would have been
an 'equation' there, and we would have had to do some work to calculate
what 'x' must be.
But as it is, there's no equation and no question, so nothing to 'answer'.
If using Avordupois there are 16 ounces (oz) to a pound (lb)
Therefore, 12oz x 3 = 36oz So 36oz / 16 = 3lb 4oz
7lb x 3 = 21lb, so the answer is 21lb + 3lb 4oz = 24lb 4oz
If Troy is used, there are 12oz to a pound (lb).
What is the solution of 5x plus 21-3x equals 97?
2x + 21 = 97
2x = 76
x = 38
Check it.
5 x 38 + 21- 3 x 38
190 + 21 - 114
211 - 114 = 97
It checks.
divide by 2 to give 3.5x = y
That is all you can do without further information about x.
What does a 4inches x 8inches x 16inches hollow concrete block weigh?
you need to have the density of the concrete block. after you find it, use the formula density = mass/volume --> mass = density x volume to calculate the mass. if you want to find the weight in Newtons, use W = mg where m is the mass and g is 9.81N/kg. that will give you the weight of the block.
for this case, the volume is 4m x 8m x 16m ( i assume it is in metres cos no units were given) = 512m^3. find the density in kg/m^3 and use the above formula mass = density x volume to calculate the mass. use W = mg to find the weight of the block in Newtons.
297 x 420 x 2 = 0
(297 x 420) = 124740
(124740) x 2 = 249480
What is the answer to 7x-9 equals 3x plus 5?
7x - 9 = 3x + 5
7x - 3x - 9 = 5
7x - 3x = 5 + 9
4x = 14
x = 14/4
How do you do y equals 2x plus 3 and y equals 3x plus 1?
Both equations are equal and so:
3x+1 = 2x+3
3x-2x = 3-1
x = 2 and by substituting y = 7
Is critical point also an inflection point?
no, a critial point is where the slope (or the derivitive) is 0. the inflection point is when the graph switches from concave up to concave down or vice versa
Is 3 times 6 the same as 18 divided by 6?
No, no the answers 18 and 3differ by factor 6
3 x 6 = 18 (not 3) and
18 / 6 = 3 (not 18)
How do you solve 9X plus 7 equals 4X - 8?
Here are the steps:
-- Write the equation.
-- Subtract 7 from each side of the equation.
-- Subtract 4x from each side.
-- Divide each side by 5.
Why time periods is equal of pendulum?
A simple pendulum, ideally consists of a large mass suspended from a fixed point by an inelastic light string. These ensure that the length of the pendulum from the point of suspension to its centre of mass is constant.
If the pendulum is given a small initial displacement, it undergoes simple harmonic motion (SHM). Such motion is periodic, that is, the time period for oscillations are the same.
What are the zeros of q(x) x(x - 3)(x 5).?
It is difficult to be sure because the browser used for posting questions is pretty much useless and strip out most mathematical symbols. Having made that clear, the answer is probably 0, 3 and -5.
