MATH

Answer 1

@akitav

Answer 2

in form a+bi? multiply and divide by 8+3i ( conjugate of the denominator)

Answer 3

I got 52/73 - 17/73i

Answer 4

remember to use \[(a+b)(a-b) = a^2-b^2\]and \[i^2=-1\]

Answer 5

yes

Answer 6

what did u get akitav

Answer 7

absolutely correct :)

Answer 8

i got the same answer

Answer 9

dude were AWESOME!!!!

Answer 10

Solve for X:

Answer 11

\[x ^{19} -2x ^{18} + 7x ^{17} -12x ^{6} + 6x ^{15} =0\]

Answer 12

0,1 and +/- \[\sqrt{6i}\]

Answer 13

or its 0,1 and +/- 6i

Answer 14

the first one 0,1, \[i \sqrt{6}\]

Answer 15

you forgot the +/-

Answer 16

right, Give me one more then I have to go for my class. will be back in two hours

Answer 17

ok

Answer 18

For the polynomial function ................ find the zeros. Then determine the mutiplicity at each zero and state whether the graph sidplays the behavior of a touch or a cross at each intercept.

Answer 19

\[f(x)= x ^{4} -25x ^{2}\]

Answer 20

zeroes are 0,0,5,-5

Answer 21

x = 0, cross; x = −5, cross; x = 5, touch
x = 0, cross; x = −5, cross; x = 5, cross
x = 0, touch; x = −5, cross; x = 5, cross
x = 0, cross; x = −5, touch; x = 5, touch

Answer 22

crosses the axis at x= 5 and x= -5

Answer 23

A. x = 0, cross; x = −5, cross x = 5, touch
B. x = 0, cross x = −5, cross x = 5, cross
C. x = 0, touch x = −5, cross x = 5, cross
D. x = 0, cross x = −5, touch x = 5, touch

Answer 24

touches at x = 0

Answer 25

option C

Answer 26

ok

Answer 27

one more or no

Answer 28

alright, but really gotta go after this one

Answer 29

Find the local and global extrema for the polynomial function f whose complete graph is provided

Answer 30

No local extrema exist.
The local and global extrema are: (-7, 45), (-4, -20), (0, 3), (4, -20) and (7, 45).
No global extrema exist.
The local and global extrema are: (-4, -20), (0, 3) and (4, -20).

Answer 31

The local and global extrema are: (-4, -20), (0, 3) and (4, -20).

Answer 32

extrema means the largest or the smallest value in a bounded neighborhood
