find the internal representation of 531, if the computer uses a 32 bit memory location to store each number
Fudgin [204]

The internal representation of 531 using a 32 bit memory location to store each number is; 00000000000000000000001100100001

<h3>Representation of numbers in the computer</h3>

When representing numbers, they are divided by 2 as follows;

  • 531/2 = 265 remainder 1

  • 265/2 = 132 remainder 1

  • 132/2 = 66 remaining 0

  • 66/2 = 33 remainder 0

  • 33/2 = 16 remainder 1

  • 16/2 = 8 remainder 0

  • 8/2 = 4 remainder 0

  • 4/2 = 2 remainder 0

  • 2/2 = 1 remainder 0

  • 1/2 = 0 remainder 1

Hence, the representation of 531 in a computer using a 32 bit memory is;

  • 00000000000000000000001100100001.

What is the measure of U
iris [78.8K]

Answer:

U = 48

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

x+21 + x+23 + x+61 = 180

Combine like terms

3x + 105 = 180

Subtract 105 from each side

3x+105-105 = 180-105

3x = 75

Divide by 3

3x/3 = 75/3

x = 25

We want angle u

x+23

25+23

Let f(x) = 9x3+ 21x2^ - 14 and g(x) = 3x + 1. Find "<br>f (x) over g (x)​
kondor19780726 [428]

Answer:

\frac{f(x)}{g(x)}=3x^2+6x-2-\frac{12}{3x+1}

Step-by-step explanation:

The first function is f(x)=9x^3+21x^2-14

The second function is g(x)=3x+1.

\frac{f(x)}{g(x)}=\frac{9x^3+21x^2-14}{3x+1}

We perform the long division as shown in the attachment to obtain the quotient as: Q(x)=3x^2+6x-2 and remainder R=-12.

Therefore:

\frac{f(x)}{g(x)}=3x^2+6x-2-\frac{12}{3x+1}

where x\ne -\frac{1}{3}
