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.

-3y+5=-4 subtract 5 from each side of the equation: -3y=-9 Divide by -3 to get the variable alone:
y=3
No.
Remember: sin2 + cos2 = 1
So, in place of (1 - 2 sin2) we can write (sin2 + cos2 - 2 sin2).
Massage that around slightly: (sin2 + cos2 - 2 sin2) = cos2 - sin2
That's not equal to (sin2 - cos2), which is the original question we were asked.
How do you solve the equation 81t3 - 81t equals 0?
You factor it.
81t3 - 81t = 0
Divide by 81:
t3 - t = 0
Take out the common factor t:
t (t2 - 1) = 0
Here we have a difference of two squares, therefore:
t (t + 1) ( t - 1) = 0
If the product is zero, that means that one of the factors must be zero, so you have to solve the three equations:
t = 0 OR t + 1 = 0 OR t - 1 = 0.
In summary, t can be 0, -1, or 1.
What mistake do people make to solve for 1 equals 2?
Most people who believe that 1 = 2 make the mistake of dividing by zero:
If 1 X 0 = 2 X 0,
then you might suppose that 1 = 2, by cancelling the common factors, namely the factor of zero.
But you would be *absolutely* wrong to think this.
If it were correct, then all numbers would be equal. That would probably suit the Ministry of Education very well; not to mention the teachers' unions, as well as some nihilist philosophy students. But the bankers will never have it, and, so, the Indiana state legislature is in no danger of passing it. At last report, Indiana has not legislated the value of pi, either.
What is 10.99 x 5 and 2 thirds?
(10.99) x (5 2/3) = (10.99) x (17/3) = 186.83/3 = 62.27666 (rounded, repeating)
Does light from the sun travel at 186282 miles per second?
Yes. And it takes about 8 1/2 minutes for it to reach the earth.
How do you log in to kidspace?
write kidspace then if you have it do the second one.next write your username and password.last press log in press agree when a different thing comes up and there you have it.

Because when collated together the discriminant of b2-4ac = -32 i.e. 144-(4*2*22) = -32
In order for the parabolas to make contact with each other the discriminant must equal zero or be above zero.
Would the function x4 plus 1 over x3 minus 2x be even or odd and how would you solve it?
For a function to be even, f(x)=f(-x) for all x
For a function to be odd: -f(x) = f(-x) for all x
Applying this to your formula,
assume that the function is even. Then for x = 2
2^4 + 1/2^3 - 2(2) = (-2)^4 + 1/(-2)^3 - 2(-2)
simply this cannot be true and therefore it is not even. This approach should be done using x and -x in the place of a number but a number indicates the result clearly and will prove it false. To prove a function. You would need to ensure that the statement holds for all x
Similarly for odd a similar process is taken.
How will you compare 3x 4y equal to less than 12 and 3x 4y equal to greater than 12?
They are two regions of the Cartesian plane with the straight line 3x + 4y = 12 defining their boundary. That line is not part of either region.
