Answer:
|a| = 0.447
|b| = 0.547
|c| = 0.707
Step-by-step explanation:
From available data
Ψ1 = Ee = 10eV probability = 0.2
Ψ2 = Ee = 16eV, probability = 0.3
Ψ3 = Ee = 34eV, probability = 0.5
The magnitude of a
= a² = 0.2
= a = √0.2
|a| = 0.447
The magnitude of b
b² = 0.3
b = √0.3
|b| = 0.547
The magnitude of c
c² = 0.5
c = √0.5
|c| = 0.707
So in conclusion we have magnitude of a = 0.447
b = 0.547
c = 0.707
Answer:
f(x) = 3x² - 12x -135
Step-by-step explanation:
standard form of a quadratic equation is
y = Ax² + Bx + C
You are given 3 solutions for X and Y, i.e( x=-5, y = 0), (x = 9,y = 0) and (x = 8,y = -39)
Substitute each of this equations into the quadratic equation to obtain a system of 3 equations
For ( x=-5, y = 0), 25A - 5B + C = 0 ---------- eq (1)
For ( x= 9, y = 0), 81A + 9B + C = 0 ---------- eq (2)
For ( x= 8, y = -39), 64A + 8B + C = -39 ---------- eq (3)
You have 3 equations and 3 unknowns. Solving this system of 3 equations will give:
A = 3, B = -12, c = -135
Hence the quadratic equation is
y = 3x² - 12x -135
or in function form:
f(x) = 3x² - 12x -135
Answer:
.666666667
Step-by-step explanation:
to get x alone you divide 90 and 60 each by 90. X would be left on the left side and 60 divided by 90 is .666666667
The correct answer is "D".
q+r=p
Because the missing angle would equal 180-q-r, it would be the same as p. The one angle (the unmarked) is supplementary to the missing angle. (180 degrees)
I hope this helps!
