Answer:

1) yes

2) No

3) No

4) yes

5) No

Step-by-step explanation:

1) f(0)=0, f(1)=1, f(2)=2, f(3)=3, then $f[\{0, 1, 2, 3\}]=\{0, 1, 2, 3\}$

2) f(0)=0, $1^2=1\equiv 1 \text{mod 4}$ , then f(1)=1; $2^2=4\equiv 0 \text{ mod 4}$ , then f(2)=0; $3^2=9\equiv 1 \text{mod 4}$ , then f(3)=1

Then $f[\{0, 1, 2, 3\}]=\{0, 1, 3\}$ , this means that f isn't onto.

3.

f(0)=0;

$1^1-1=0$ , then f(1)=0
$2^2-2=2$ , then f(2)=2
$3^2-3=6\equiv 2 \text{ mod 4}$ , then f(3)=2

Then $f[\{0, 1, 2, 3\}]=\{0, 2\}$ , this means that f isn't onto.

4. $f[\{0, 1, 2, 3\}]=\{0, 1, 2,3\}$ , then f is onto.

5. $f[\{0, 1, 2, 3\}]=\{1, 2\}$ , this means that f isn't onto.

Find the sum of the measures of the interior angles:

Tresset [83]

The sum of the measures of the interior angles

The sum of interior angles of any polygon can be foud wuth the following general formula

Sum of interior angles = (n-2) \ times 180^{\circ}

where n is the number of sides

<u>1. Nonagon</u>

The Nonagon is a polygon with 9 sides. then,

n = 9

Sum of interior angles of Nonagon

= $(9-2) \times 180^{\circ}$

= $(7) \times 180^{\circ}$

= $1260^{\circ}$

<u>2.Pentagon</u>

The Pentagon is a polygon with 5 sides. then,

n = 5

Sum of interior angles of Pentagon

= $(5-2) \times 180^{\circ}$

= $(3) \times 180^{\circ}$

= $540^{\circ}$

<u>3. 11-gon</u>

The 11-gon is a polygon with 11 sides. then,

n = <u>11</u>

Sum of interior angles of 11-gon

= $(11-2) \times 180^{\circ}$

= $(9) \times 180^{\circ}$

= $1620^{\circ}$

<u>4. 18-gon</u>

The 18-gon is a polygon with 18 sides. then,

n = 18

Sum of interior angles of 18-gon

= $(18-2) \times 180^{\circ}$ <u></u>

= $(16) \times 180^{\circ}$

= $2880^{\circ}$

<u>5. 38-gon</u>

The 38-gon is a polygon with 38 sides. then,

n = 38

Sum of interior angles of 38-gon

= $(38-2) \times 180^{\circ}$

= $(36) \times 180^{\circ}$

= $6480^{\circ}$

<u>6.56-gon</u>

The 56-gon is a polygon with 56 sides. then,

n = 56

Sum of interior angles 56-gon

= $(56-2) \times 180^{\circ}$

= $(54) \times 180^{\circ}$

= $9720^{\circ}$
