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.

310 can be divided by 1, 2, 5, 10, 31, 62, 155, and 310. These are factors of 310, meaning they can divide 310 evenly without leaving a remainder.
significant figures.
For any number, the sf is the number of digits from the first non-zero digit to the last non-zero digit. Any zeros within that range ARE counted.
So, for example,
1.23000 sf = 3
1.0230 sf = 4
00567.5 sf = 4
5.000000001 sf = 10
What is the value of x in the equation 7x - 3 32?
Oh, dude, the value of x in that equation is 5. Like, you just add 3 to both sides, then divide by 7. It's like basic math, man.
Why does the period of tan x equals pi?
If you look at the graph of the tangent function, you will see it has a vertical asymptote at x = pi/2. This is because the tangent approaches infinity as t approaches pi/2. It approaches negative infinity as t approaches -pi/2.
The distance between - pi/2 and pi/2 is pi which is the period.
Another way to see this is tanx is sinx divided by cosx.
We cannot have cosx equal to zero or we would be dividing by zero.
So when does cosx=0? It happens when x=pi/2 or -pi/2. It also equal 0 as
multiples, both positive and negative ones, or pi/2 such as 3pi/2, 5pi/2 etc.
2 x 22 equals 44. Multiplying 2 by 22 gives you the product of 44. In this case, 22 is the number that, when multiplied by 2, equals 44.
Oh, dude, there are so many ways you can get to 41! Like, you could do 20 + 21, or maybe 82 - 41, or even 2 * 20. Like, the possibilities are endless, man. Just throw some numbers together and see what sticks!
Since the scale factor of the moon to the earth is 1:4, then the ratio of their areas will be the scale factor squared or 1:16. The ratio of their volumes will be the scale factor cubed or 1:64.
Well, darling, 2x plus 5 is just an algebraic expression that represents the sum of 2 times a variable x and 5. So, if you want to find the value of that expression, you need to know the value of x. Math can be a real hoot sometimes, can't it?
Ans: ?
But all hope is not lost
You can cheat and do other things you must b3 asking why i beacause the math is too fricking hard 😬😧😦😭
Bye...
And hope this help😇🙋
What percent of increase from 20 to 39?
Well, honey, that's a 95% increase. So, basically, you went from 20 to 39, which is a jump of 19. Divide that by the original number (20) and multiply by 100 to get your percentage. Voila, math magic!
How do you graph y equals - x 2?
This would be an upside-down parabola, with it's apex being at {0,0}. You can graph it by taking a few values of x (-2, -1, 0, 1, and 2 would be enough), finding their corresponding y positions(-4, -1, 0, -1, and -4 respectively), plotting them on the graph paper, and roughly sketching the curve that they follow.
In mathematics, the notation "y3" typically represents the cube of the variable "y," which is equivalent to y * y * y. This is a shorthand way of denoting the result of multiplying y by itself three times. The cube of a number is the number raised to the power of 3.
Why do halogens become less reactive down the column?
It's easier for halogens to gain an electron than to let seven electrons go to become reactive.
---------------------------------------------------------------------------
The further down the column you go the more electron shells in between the nucleus and the outside shell there are and so it has less 'pulling power' to grab that extra electron.
How do you factorise x squared plus 7x?
Oh, what a happy little math problem we have here. To factorise x squared plus 7x, we can first look for a common factor, which in this case is x. So, we can factor out an x to get x(x + 7). And just like that, we've created a lovely little factorised expression.
What is the answer to 3x plus 9?
The answer to the expression 3x + 9 depends on the value of x. If x is a specific number, you would first multiply 3 by that number, then add 9 to the result. For example, if x = 2, the answer would be 3(2) + 9 = 6 + 9 = 15. However, if x is a variable, the expression 3x + 9 remains as is and cannot be simplified further without knowing the specific value of x.
Well, isn't that just a happy little math problem we have here? To find the product of 9x and 5x, you simply multiply the coefficients (9 and 5) to get 45, and then multiply the variables (x and x) to get x^2. So, the answer is 45x^2. Just like painting a beautiful landscape, math can be a joyful experience when you take it step by step.
What does x equal in 10x plus 2 equals 62?
10x + 2 - 62
Subtract '2' from both sides
10x = 60
Divide both sides by '10'/
x = 6 The answer!!!!!
The expression "10 x 10" represents the multiplication of 10 by itself, resulting in 100. Multiplying 100 by itself 100 times can be expressed as 100^100, which is an extremely large number with 201 digits. This number is known as a "googol," which is significantly larger than the total number of atoms in the observable universe.
300 x 300 equals 90,000. This is because when you multiply two numbers, you are essentially adding one number to itself as many times as the value of the other number. In this case, you are adding 300 to itself 300 times, which equals 90,000.
Oh, dude, you're hitting me with some math now? Okay, like, y squared plus y is technically y(y+1). So, like, if you're ever at a party and someone asks you that, you can just drop that knowledge bomb and impress everyone.
What is the derivative of 3cosx?
The derivative of 3cos(x) is -3sin(x). This can be found using the chain rule, which states that the derivative of a composition of functions is the derivative of the outer function evaluated at the inner function, multiplied by the derivative of the inner function. In this case, the derivative of cos(x) is -sin(x), and when multiplied by the constant 3, we get -3sin(x) as the derivative of 3cos(x).
