Answer:
the value of x is twenty nine
Answer:
The expression in standard form is -3 + 6i
Step-by-step explanation:
Writing complex equation in standard form we have;
-3 + yi = x + 6i
We transfer the real and imaginary parts to be on different sides of the equation as follows;
yi - 6i = x + 3
We factorize the imaginary part;
i(y-6) = x + 3
We note that the real portion on the left hand side of the equation is zero, therefore, we have;
i(y-6) + 0= x + 3
x + 3 = 0
Therefore, x = -3
Substituting the value of x in the first equation, we have;
-3 + yi = -3 + 6i
Comparing gives;
y = 6
The expression in standard form is -3 + 6i.
Answer:
Step-by-step explanation:
<u>Solving</u>
- 3tanx = -4
- tanx = -4/3
- tan values are negative in the 2nd and 4th quadrant
- The base value is x = 53°
In <u>Quadrant II</u>,
- 90° + 53°
- ⇒ <u>x = 143°</u>
In <u>Quadrant IV</u>,
- 270° + 53°
- ⇒ <u>x = 323°</u>
You do 100 times .3 and that equals 30.
