Its different because when u add 645 and 738 it equals 1,382 and when u add 645 and 649 it equals 1,294 so 1,382 is the greater number and its different from 1,294<span />
Answer:
Graphs 1, 2, 3
Step-by-step explanation:
Graph 1 represents a <u>linear function</u> with a domain containing all real numbers, as any input substituted into the equation or function will produce a corresponding output. The arrows on the opposite ends of the line represents the infinite input values that have its corresponding output values.
Graph 2 represents a <u>quadratic function</u> with a domain containing all real numbers, as it does not have any constraints in terms of input values. As it opens up, the graph of the parabola infinitely widens (horizontally).
Graph 3 represents an <u>absolute value function</u> with a domain containing all real numbers. Similar to the explanation for graph 2 on quadratic functions, the downward-facing graph of the given absolute value function widens infinitely horizontally, as it does not have any constraints on input values.
They are right except for 12. i think it is C but i could be wrong.
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

I hope this helps. If you need another explanation just message me
