Answer:
The following numbers ARE functions:
2, 3, 6, 7, 9, 12
Step-by-step explanation:
A function is only possible if the x values have NO REPEATING NUMBER!!!
Every number that isn't mentioned above has at least 1 number in it's x-values that repeats.
<u>Question 1</u> has the 8 and 4 with 2 numbers.
<u>Question 4</u> the 3 repeating. (There are 2 dots over the 3)
<u>Question 5</u> has numbers 1 and 5 repeating many times
<u>Question 8</u> numbers 1 and 2 are repeated twice
<u>Question 10</u> number 3 repeats twice
<u>Question 11</u> has the 1 repeated
In euros Derek has twenty two dollars and eighty cents
<h2>Solution :- </h2>
Let the number be "x" , then according to the question :
• 2x - 12 = -8
Further solving
→ 2x = -8 + 12
→ 2x = 4 .
→ x = 2
<span>The exact solution of cos (17</span>π<span>/6) is as follows:
First change the angle into degrees.
17(</span>π/6) (180°/π) = 510°
Then we calculate the cosine of the angle above and it as follows:
cos 510° = -(√3)/2
Hope this answers the question. Have a nice day.
