Can anyone help me with this problem ?

Come now !  I'm sure you could unravel it if you look at it and think about it
for a minute or two.

What's an angle bisector ?  It's a line that splits an angle exactly in half.
The two little angles on each side of it are EQUAL.  Each of them is exactly
half of the big angle.

So in this drawing,    (3/2 x - 6)    is equal to    (1/4 x + 4) .
Do you think you could find 'x' ?

3/2 x - 6  =  1/4 x + 4

Add 6 to each side of the equation:    3/2 x = 1/4 x + 10

Multiply each side by 4 :                     6 x = x + 40

Subtract 'x' from each side:                  5 x = 40

Divide each side by 5 :                          x = 8

Angle  CBD  is  1/4 x + 4 .  That's  1/4 (8) + 4 = 2 + 4 = <u>6 degrees </u>

You invest $3000 in an account that pays simple interest of 7% for 30 years. how much will you have at the end of 30 years?
nekit [7.7K]
$9,300
First, multiply your beginning amount by the percent of interest: 3,000x0.07 = 210
Then, multiply your interest times the number of years:
210x30 = 6,300
Add you interest to your initial amount:
3,000 + 6,300 = 9,300

Multiplication in GF(24 ): Compute A(x)B(x) mod P(x) in GF(24 ) using the irreducible polynomial P(x) = x 4 + x + 1, where A(x)
tankabanditka [31]

Answer:

Step-by-step explanation:

hello,

i advice you check the question again if it is GF(2^{4}) or GF(24). i believe the question should rather be in this form;

multiplication in GF(2^{4}): Compute A(x)B(x) mod P(x) = x^{4} + x+1, where A(x)=x^{2}+1, and B(x)=x^{3} + x+1.

i will solve the above question and i believe with this you will be able to solve any related problem.

A(x)B(x)=(x^{2} +1) (x^{3}+x+1) mod (x^{4}+x+1  ) = (x^{5} +x^{3}+x^{2}  ) + (x^{3}+x+1  ) mod (x^{4} + x+1 )

= x^{5}+2x^{3} +x^{2}  + x + 1 mod(x^{4}+x+1  )

=2x^{2} +1

please note that the division by the modulus above we used

\frac{x^{5}+2x^{3}+x^{2} +1  }{x^{4}+x+1}= x+\frac{2x^{3} +1}{x^{4}+x+1}
