The real part of given complex number -3 + 9i is -3
<em><u>Solution:</u></em>
We have to find the real part of complex number -3 + 9i
A Complex Number is a combination of real Number and an imaginary Number
<em><u>The general form of complex number is:</u></em>
a + bi
Where "a" and "b" are real numbers and i is the unit imaginary number
The given complex number is:
-3 + 9i
On comparing the above complex number with general form of complex number we get,
Real part = -3
Thus real part of given complex number is -3
Triangle XYZ is equilateral, so the central angle of the sector is 120°, or 2π/3 radians. The area of a sector of central angle β is given by
.. A = (1/2)r^2*β . . . . . . β in radians
Your sector's area is
.. A = (1/2)*2^2*(2π/3) = 4π/3 . . . . square units
7 out of 50 people so to find the whole amount u must multiply 50x8 to =400 and multiply 7x8 =56 therefore 56 out of 400 have traveled to a foreign country. however 56 is not MORE THAN 56. if it said 56 or more he would be correct but because he says more than 56 he is incorrect. hope that helps!
Answer:
Step-by-step explanation:
The given equation is:
so, we first isolate the exponential form that contains the unknown "z" in the exponent, by dividing both sides by 0.5:
Now we bring the exponent down by applying the natural log function on both sides, and then solve for "z":
Is there any choices for it
