Answer:

-x^2+x+1 will be the remainder generated when we divide x^7+x^5+1 by x^3+1,we will use simple division method or the prime factorization.

Answer:

The answer is 1011 in 1's complement.

Explanation:

Checksum is the process of summing the characters during the transmission.Adding the sum of the characters in the message end and transmit that character message.If both sums are equal , then there is no error during transmission of data. If both the sums are not equal , then there is error during the transmission data.

0010

    10

0100 =

Take one's complement 1100.

1's complement 0100 is 1011.

A man on a 135-ft vertical cliff looks down at an angle of 16°13' and sees his friend.
iren2701 [21]
A) Use the trigonometric function and ratio cos(x) = A/H. (Adjacent/Hypotenuse)
1. cos(x) = 135/H
2. H*cos(16°) = 135
3. H = 135/cos(16°)
***Make sure calculator is in degree mode***
4. H = 140.44 ft (rounded to two decimal places)
________

b) Use the function and ratio tan(x) = O/A (Opposite/Adjacent)
1. tan(x) = O/A
2. tan(16°) = O/135
3. 135*tan(16°) = O
4. O = 38.71 ft (two decimal places)

Good luck!

Danny wants to buy a truck in 4 years. He is going to put away $2,500.00 into his savings account that will pay him 6.75% intere
aniked [119]

Answer:

b $3,272.43

Step-by-step explanation:

A = p(1+r/n)^nt

Where

A= future value

P= principal = $2500

r= interest rate = 6.75% = 0.0675

n = number of periods = 12

t = time = 4 years

A = p(1+r/n)^nt

= 2500(1+0.0675/12)^12*4

= 2500(1+0.005625)^48

= 2500(1.005625)^48

= 2500(1.3089737859257)

= 3272.4344648144

Approximately

A= $3272.43

He will have $3272.43 to give as down payment in 4 years
