Both have the same denominator
Remove the denominator
5=n
Answer:
2.08%
Step-by-step explanation:
The probability of a snowfall on any given night is 1/8.
The probability that the father is telling the truth is 1 - 5/6, or 1/6.
Then:
1/6 x 1/8=1/48=0.0208, or 2.08% ............
Well, to solve, garph the equation y=x^2+2x-8 and y=0
see where they intersect
anyway the easier way is to factor but anyway
0=(x-4)(x+2)
anyway
solution is x=4 and -2
A and D are answers (they are same)
Answer:5
Step-by-step explanation:
Answer:
3(cos(75°) +i·sin(75°)) and 3(cos(255°) +i·sin(255°))
Step-by-step explanation:
Using Euler's formula, this can be written as ...
x^2 = 9·e^(i5π/6)
Then the square roots are ...
x = (±√9)e^((i5π/6)/2) = ±3e^(i5π/12)
Of course, multiplying by -1 is the same as adding 180° to the angle.
The square roots are ...
3(cos(75°) +i·sin(75°)) and 3(cos(255°) +i·sin(255°))
