The answer is:
By definition, a point is a local minimum if it has the smallest <em>y</em> coordinate in that interval and the graph goes from decreasing to increasing.
Based on this information, you can graph the points given in the problem above, as you can see in the figure attached. Then, you can notice that the ordered pair that is closest to a local minimum of the function is the last option shown in the problem.
Answer:
Step-by-step explanation:
<u>Complex Numbers</u>
They are expressed as the sum of a real part and an imaginary part:
Complex numbers can also be expressed in polar form:
Where r is the modulus of the complex number and θ is the argument.
The argument can be calculated by:
The angle θ must be calculated in the appropriate quadrant depending on the signs of the real and imaginary parts.
The complex number is given as:
Here: a=-3, b=-9
Since both components are negative, the argument lies in the third quadrant (180° < θ < 270°).
The calculator gives the answer 71.6°, we need to adjust the angle to the third quadrant by adding 180°, thus
