Answer:

  4 in

Step-by-step explanation:

The Pythagorean theorem tells you the square of the hypotenuse is equal to the sum of the squares of the other two sides. Solve this problem by writing that relationship using the given information, then solving the equation for the missing side.

__

  5² = 3² + ?²

  25 = 9 + ?² . . . . . simplify

  16 = ?² . . . . . . . . . subtract 9

  4 = ? . . . . . . . . . . . take the square root

1)Convert the following binary numbwers into decimal number(only a,b,c,f,i)<br>​
kozerog [31]

Answer:

a) 3₁₀

b) 6₁₀

c) 7₁₀

f) 19₁₀

i) 181₁₀

Step-by-step explanation:

<u>Binary to Decimal Conversion (Positional Notation Method)</u>

  • Multiply each digit by the base (2) raised to the power dependent upon the position of that digit in the binary number.
  • Sum all the values obtained for each digit.
  • Express the number as a decimal number by placing subscript 10 after it.

For a binary number with 'n' digits:

  • The right-most digit is multiplied by 2⁰
  • The left-most digit is multiplied by \sf 2^{n-1}

For example, to convert the binary number 111001₂ into a decimal:

\begin{array}{ c c c c c c}1 & 1 & 1 & 0 & 0 & 1\\\downarrow & \downarrow & \downarrow & \downarrow & \downarrow & \downarrow \\2^5 & 2^4 & 2^3 & 2^2 & 2^1 & 2^0\\\end{array}

Multiply each digit by the base (2) raised to the power as indicated above and sum them:

=(1 \times 2^5)+(1 \times 2^4)+(1 \times 2^3)+(0 \times 2^2)+(0 \times 2^1)+(1 \times 2^0)

= 32+16+8+0+0+1

= 57

Finally, express as a decimal number ⇒ 111001₂ = 57₁₀

<u>Question (a)</u>

\begin{aligned}\implies 11_2 & = (1 \times 2^1)+(1 \times 2^0)\\& = 2+1\\& = 3\end{aligned}

Therefore, 11₂ = 3₁₀

<u>Question (b)</u>

\begin{aligned}\implies 110_2 & = (1 \times 2^2)+(1 \times 2^1)+(0 \times 2^0)\\& = 4+2+0\\& = 6\end{aligned}

Therefore, 110₂ = 6₁₀

<u>Question (c)</u>

\begin{aligned}\implies 111_2 & = (1 \times 2^2) +(1 \times 2^1)+(1 \times 2^0)\\& =4+2+1\\& = 7\end{aligned}

Therefore, 111₂ = 7₁₀

<u>Question (f)</u>

\begin{aligned}\implies 10011_2 & =(1 \times 2^4)+(0 \times 2^3)+ (0 \times 2^2) +(1 \times 2^1)+(1 \times 2^0)\\& =16+0+0+2+1\\& = 19\end{aligned}

Therefore, 10011₂ = 19₁₀

<u>Question (i)</u>

\phantom{)))}10110101_2 \\\\=(1 \times 2^7)+(0 \times 2^6)+(1 \times 2^5)+(1 \times 2^4)+(0 \times 2^3)+ (1 \times 2^2) +(0 \times 2^1)+(1 \times 2^0)\\\\=128+0+32+16+0+4+0+1\\\\= 181

Therefore, 10110101₂ = 181₁₀
