Answer:Since the integers are closed under addition, . m C n C 1/ is an integer, and hence the last equation shows that x C y is even. Therefore, we Page 3 Appendix C. Answers for Exercises 539 have proven that if x and y are odd integers, then x C y is an even integer. P1 There exists an integer k m D 2k.

What are the sizes of angles a, b, c and d?

Lilit [14]

Answer:

a = 26°

b = 48°

c = 26°

d = 106°

Step-by-step explanation:

$c + {154}^{o} = {180}^{o} \\ c = {180}^{o} - {154}^{o} \\ c = {26}^{o}$

a = c (Alternate angles)

$a = {26}^{o}$

$b = {48}^{o}$

Corresponding angles

(a + d) + b = 180° (Interior angles)

${26}^{o} + d + {48}^{o} = {180}^{o} \\ d + {74}^{o} = {180}^{o} \\ d = {180}^{o} - {74}^{o} \\ d = {106}^{o}$

The graph shows the temperature of ice cream in an ice chest during an overnight trip. What is the domain of this function?

mariarad [96]

Let

x-------> the number of hours

y------> the temperature in degrees Fahrenheit

we know that

For $x=0\ hours$

$y=-10\°\ F$

For $x=30\ hours$

$y=30\°\ F$

The domain of the function is the interval----------> $[0,30]$

$0\ hours \leq x\leq 30\ hours$

The range of the function is the interval----------> $[-10,30]$

$-10\°\ F \leq y\leq 30\°\ F$

therefore

<u>the answer is</u>

The domain is all real numbers 0 through 30

Answer:

200 cm^2

Step-by-step explanation:

Add up all areas

4 x 6 x 1/2 = 12

4 x 6 x 1/2 = 12

3 x 11 = 33

3 x 11 = 33

6 x 11 = 66

12 + 12 + 33 + 33 + 66 = 200
