Hello!</h2>
The answer is:
The simplified fraction is:
<h2>Why?</h2>
To solve this problem we must remember the following:
- Addition or subtraction of fractions, we add or subtract fractions by the following way:
- Product of fractions, the multiplication of fraction is linear, meaning that we should multiply the numerator by the numerator and denominator by denominator, so:
- Convert mixed number to fraction,
So, solving we have:
Hence, the simplified fraction is:
Have a nice day!
Answer:
1. acute angle with 74°
2. acute angle with 55°
Step-by-step explanation:
any angles less than 90° is acute
any angles that are 90° are right angles
any angles over 90° above are obtuse
Answer:
The Answer to 17 1/3 x 8 is 138.67
There is not enough context to answer the second question.
<span>we have that
the cube roots of 27(cos 330° + i sin 330°) will be
</span>∛[27(cos 330° + i sin 330°)]
we know that
e<span>^(ix)=cos x + isinx
therefore
</span>∛[27(cos 330° + i sin 330°)]------> ∛[27(e^(i330°))]-----> 3∛[(e^(i110°)³)]
3∛[(e^(i110°)³)]--------> 3e^(i110°)-------------> 3[cos 110° + i sin 110°]
z1=3[cos 110° + i sin 110°]
cube root in complex number, divide angle by 3
360nº/3 = 120nº --> add 120º for z2 angle, again for z3
<span>therefore
</span>
z2=3[cos ((110°+120°) + i sin (110°+120°)]------ > 3[cos 230° + i sin 230°]
z3=3[cos (230°+120°) + i sin (230°+120°)]--------> 3[cos 350° + i sin 350°]
<span>
the answer is
</span>z1=3[cos 110° + i sin 110°]<span>
</span>z2=3[cos 230° + i sin 230°]
z3=3[cos 350° + i sin 350°]<span>
