Answer:
<h2>4</h2>
Step-by-step explanation:
A complex number in its rectangular form is expressed as x+iy where x is the real part of the complex number and y is the imaginary because it is attached to the imaginary number i.
Given the complex number 4-5i, comparing the complex number with x+iy
4 = x and iy = -5i
Hence x = 4 and y = -5.
Since x is the real part of the complex number x+iy,<em> hence 4 will be the real part of the complex number 4-5i based on comparison. </em>
Answer:
A
Step-by-step explanation:
For b, the constant term is 3, not -3. B is incorrect.
For c, when the brackets are removed using foil, -3 * - 3 = 9. C is incorrect.
For d, There is no reduction, alteration or math procedure that you can use that will make the constant term anything but 9. The answer is not D.
======================
That means you are left with A which must be right or the question isn't. Turns our that A is the answer -3 * 1 = - 3
Answer:
17.0
Step-by-step explanation:
If you take the sin(39) or cos(51), it is equal to BC/27. Multiply by 27 on both sides to get 27cos(51) or 27sin(39)= x. Plug into the calculator, and voila.
