Answer:
4 + 5i
Step-by-step explanation:
To calculate this you have to combine the like terms until they cannot be combined any further:
7 + 10i + 4 - 10i - (7 - 5i)
11 + 0i - 7 - 5i
7 & 4 are liked terms so add them together + subtract 10i and 10i
4 + 5i <--- Final answer
Hope this helps!

The formula of the Trigonometric Identity Sine is,

Answer: P represents -13
Step-by-step explanation:
Since a negative x negative + positive, we know that p has to be a negative.
For me, I added both 21 and -5 (though I made it into a positive), and got 26.

So, you divide 26/-2, which then becomes -13.
Thus, p=-13 :)
Answer:
See below.
Step-by-step explanation:
A. k = 50 * 3.6 = 180.
B. The equation is y = 180/x.
C. When x = 75, y = 180/75
= 2.4.
D. Checking C: 2.4 = 180/75 = 2.4. Correct
