What is the factor of x2y-xyb-abx plus ab2?
(b - x)(ab - xy)
Triangle abc is a right triangle if ac equals 4 and bc equals 10 find ab?
The question is poorly specified, since the given triangle can be right angled at A or C. If it is right angled at A, then bc2 = ab2 + ac2 so that ab2 = 100 - 16 = 84 and ab = sqrt(84) = 9.165 Or it is right angled at C, and ab2 = bc2 + ca2 = 100 + 16 = 116 so that ab = sqrt(116) = 10.770
What is the LCM of 14ab to the second power and 42a to the second power?
The LCM is 42a2b2.
Why does b times ab equal ab squared and not equal ab plus b squared?
b*ab = ab2 Suppose b*ab = ab + b2. Assume a and b are non-zero integers. Then ab2 = ab + b2 b = 1 + b/a would have to be true for all b. Counter-example: b = 2; a = 3 b(ab) = 2(3)(2) = 12 = ab2 = (4)(3) ab + b2 = (2)(3) + (2) = 10 but 10 does not = 12. Contradiction. So it cannot be the case that b = 1 + b/a is true for all b and, therefore, b*ab does not = ab + b2
Why is the long leg the square root of 3 times bigger then the short leg in a 30 60 90 triangle?
I guess you are asking of the two sides which are not the hypotenuse, why the longer is root 3 times the shorter. Consider a 30, 60, 90 triangle ABC with ∠A = 30o, ∠B = 90o and ∠C = 60o and so side AC is the hypotenuse and BC is the shortest side. Reflect the triangle ABC in side BC to create triangle ABE. ∠EAB will be 30o, ∠ABE 90o and ∠BEA 60o. Side AE = AC. ∠EAC = ∠EAB + ∠BAC = 30o + 30o = 60o So triangle ACE is an equilateral triangle and thus side EC = AC Since EC = AC and EB = BC, EC=EB + BC ⇒ AC = BC + BC ⇒ AC = 2BC Using Pythagoras on triangle ABC to find length AB gives: AB2 + BC2 = AC2 ⇒ AB2 + BC2 = (2BC)2 ⇒ AB2 = 4BC2 - BC2 ⇒ AB2 = 3BC2 ⇒ AB = √3BC ie the shortest side is root 3 times the other non-hypotenuse side.
How is the VSEPR theory what molecular geometries are associated with the following types of molecule's AB2?
Linear
According to the vsepr theory what molecular geometries are associated with AB2?
The molecular geometry associated with AB2 molecules according to VSEPR theory is linear. This means that the two bonding pairs are arranged in a straight line with a bond angle of 180 degrees.
For a molecule with the formula AB2 the molecular shape is it a-linear b-trigonal planar c-bent d-t-shaped E-tetrahedral?
Can't tell u in general if a or b, depends on what AB2 is, e.g. CO2 is linear, H2O is tent shaped (corner at midst atom: 105o) but not trigonal as you'd call it.Anyhow c, d, E are unusual for tri-atomic.H2O is not in the form AB2. When in the form AB2 the ideal bond angle is 180 degrees or linear.See the link below.
What is the squared root of ab2?
√(ab2) = (√a)*b
What is 1574 to base twelve?
AB2
What is the gcf of 3ab3c and a3b2?
The GCF is ab2
How Gibbs adsorption isotherm equation used in a graphical method to determine surface excess concentration of AB2?
In the graphical method using the Gibbs adsorption isotherm equation, the surface excess concentration of AB2 can be obtained by plotting the surface excess Gibbs free energy against the bulk concentration of AB2 at equilibrium. The intercept of the linear plot on the y-axis gives the surface excess concentration of AB2 at the surface. This method helps quantify the extent of the surface concentration of AB2 in the system.
How can you find the base of a triangle if you know the height and hypotenuse?
Let consider the right triangle ABC with hypotenuse AB and heigth AC then base is BC Pythagorean theorem states that AB2=AC2+BC2 so BC2=AB2-AC2 then BC=sqrt(AB2-AC2)
What is the greatest common factor of a3b2 and ab2c4?
ab2
How do you factor sum or difference of two cubes and why does this process make sense?
(a -b) · (a2+ab+b2) = (a3+a2b+ab2) - (a2b+ab2+b3) = a3 -b3 (a+b) · (a2 -ab+b2) = (a3 -a2b+ab2) +(a2b -ab2+b3) = a3+b3 More generally: (a ∓ b) · (an-1 ±an-2b +an-3b2 ±an-4b3 +±...+a(±b)n-2 +(±b)n-1) = an ± bn. The mixed terms cancel out themselves.
