How do polynomial time vs. exponential time algorithms compare?
An algorithm that completes in "polynomial time" is faster to solve than an algorithm that completes in "exponential time" in most of the important cases where it needs to be solved. An algorithm that completes in "polynomial time" the time to solve is always determinable by a polynomial equation (e.g. x^2, x^4+7*x^3+12*x^2+x+19, x^8392). An algorithm that completes in "exponential time" the time to solve can only be determined an exponential equation (e.g. 2^x, e^x, 10^x, 982301^x). Exponential equations give larger value answers than polynomial equations after a certain input value and then increase progressively faster. This makes "exponential time" algorithms take much longer than "polynomial time" algorithms to solve, often making many of them effectively unsolvable for certain cases. Many of the most important algorithms needed to solve real world problems are "exponential time" algorithms.
What is the formula for calculating distance when speed and time are known?
Distance = speed x time
What is x time x?
x times x = x2 (it's like 6 times 6. it would be 62. not 6 times 2. 2x means x times 2)
Value of the impulse equals the force x the?
Time
What can be represented by coordinates x and y?
You could show the y-axis by distance and the x-axis by time.
What is 2yz x 3z?
6yz2.(Confirmed and Seconded)
What are the factors of 2yz?
factors of 2yz - 1y, 2z, 1z, 2y, 1, 2yz
What is the gcf of 4y2z2 and 10ya2z?
The GCF is 2yz.
What is the step of square of trinomial?
(x + y + z)2 = x2 + y2 + z2 + 2xy + 2yz + 2zx
What does 8x2yz plus 16xy2z2 - 24xyz2 equal?
8x2yz + 16xy2z2 - 24xyz2Factor out Greatest Common Factor (GCF), which is 8xyz:8xyz ( x + 2yz - 3z )
X plus y plus z squared?
If th equestion meant: (x+y+z)^2The expansion is:(x+y+z)^2= x^2+2xy+y^2+2yz+z^2+2zx
What are joint variation equations?
Joint variation equations are equations that have a variable equal to the product of two or more other variables and usually a coefficient. For example, an equation like x=2yz.
3 terms multiply by 3 terms?
9
What is a simplified form of -8x-4z-5x 2y z-3y?
To simplify the expression (-8x - 4z - 5x + 2yz - 3y), combine like terms. The terms (-8x) and (-5x) combine to (-13x). Thus, the simplified form is (-13x - 4z + 2yz - 3y).
How do you find the missing parts of an oblique triangle which 3 sides are given?
Let the sides be x, y, z. Let the angles opposite those sides be X, Y, Z You can use the Cosine Law which states cos X = (y^2 + z^2 - x^2)/2yz Then calculate cos^-1(or arccos X) and this will give you the angle in degrees. then do the same for Y cos Y = (x^2 + z^2 - y^2)/2xz Do the same to get Y. Then add X and Y and subtract for 180° and you have your three angles.
What is the factor of 6xyz plus 9abx?
To find the common factor of the terms (6xyz) and (9abx), we first identify the coefficients and the variables. The greatest common factor of the coefficients 6 and 9 is 3. The common variable in both terms is (x). Thus, the factor of (6xyz + 9abx) is (3x), and we can express it as (3x(2yz + 3ab)).
If x2 is an integer divisible by 3 then x is divisible by 3?
Yes. If x is not divisible by 3 then x leaves a remainder of 1 or 2 when it is divided by 3. That is, x is of the form 3y+z where z = 1 or 2. Then x2 = (3y+z)2 = 9y2 + 6yz + z2 = 3(3y2 + 2yz) + z2 The first part of this expression is clearly a multiple of 3, but z2 is not. Whether z = 1 or 2, z2 leaves a remainder of 1 when divided by 3.
