(20 points) consider the complex valued function f( which is called inversion. calculate a few examples and then describe the effect of this function. you are encouraged to calculate the function for more values of z on your own. if z-e", where te [0, 2t then the points of the unit circle are mapped to the (describe by words, will be graded manually later) 2. itz-0.9eit, where t e [o, 2? ] then-- the points inside of the unit circle are mapped to the (describe by words, will be graded manually later) 3. itz 50eil, where t c 10, 2 then- the points outside of the unit circle are mapped to the (describe by words, will be graded manually later) in addition, compared to the angle of z, the angle of is

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

they go with it happens or they mite give a chance?

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
