Find the cube root of 1+¡^5

Alla [95]

¡^5= ¡
so we have cuberoot of 1+¡
x=1 y=1
to find d modulus we have
r=squaroot of 1²+ 1²= 2
r= squaroot of 2
we find the argard diagram by using
tan(tha)=y/x
tan(tha)=1/1
tha=tan-¹ 1
tha=45
using the formula of root of complex number we have
z=r^1/n (cos(tha+2k(180))/n +¡sin(tha+2k(180)/n) when k elemen z+ and n=3
when k=0
we have
z=(squaroot of 2)^1/3 *1/2squaroot of 2
like wise when k=1 and k=2

(Picture) MULTIPLYING POLYNOMIALS AND SIMPLIFYING EXPRESSIONS PLEASE HELP!!!!

Sidana [21]

Answer:

$-2p^2-11p-35$

Step-by-step explanation:

$-2(p+4)^2-3+5p$

First we square the parenthesis. Apply FOIL method to multiply

$(p+4)^2= (p+4)(p+4)= p^2 + 4p+4p+16= p^2+8p+16$

$-2(p^2+8p+16) -3+5p$

distribute -2 inside the parenthesis

$-2p^2-16p-32-3+5p$

Now combine like terms

$-2p^2-11p-35$

A hat is 40% off the discount price of a hat is $50.40 what is the regular price

ratelena [41]

Answer:

The correct answer would be $126.00

Step-by-step explanation:

If you see how many times 40% goes into 100%, it would be 2.5 times. Then you multiply the 40% of the overall price ($50.40) times 2.5 and that gives you $126.

Hope this helps!!

4x-6>22 explain or prove if 5 or 8 is a solution to the inequality

babunello [35]

Answer:

Step-by-step explanation:

4(5) - 6 = 14

14 is not larger than 22, so 5 is not the solution.

4(8) - 6 = 26

26 is larger than 22, so 8 is the solution
