6. -√ 2 / 2
8. -√3 / 2
If you look at the chart provided, it gives you the unit circle, which has every angle in degrees, radians, and precise values.
the given is ordered as such: (cos, sin)
Let the 3 sides of a triangle be a,b and c
For it to be a triangle then
a + b > c , a + c > b , b + c > a
12 , 12 , 20
12 + 12 > 20
24 > 20
12 + 20 > 12
32 > 12
Hence is a triangle
10,3,7
3 + 7 .....10
10 = 10
Hence is not a triangle since it does not satisfy the rules above
7,7,11
7 + 7 .... 11
14 > 11
11 + 7 ..... 7
18 > 7
Hence the figure formed is a triangle
24,9,12
9 + 12 .... 24
21 < 24
Hence is not a triangle
The rule is that for 3 numbers to form the sides of a triangle then the sum of any 2 of the numbers should be equal to the third
Answer:
c 17
Step-by-step explanation:
You make 23 a day plus 3.60 per sale
Income = 23+ 3.6 s
You want to make at least 84
84 ≤ 23+ 3.6 s
Subtract 23 from each side
84 -23 ≤ 23-23 +3.6s
61 ≤ 3.6s
Divide by 3.6 on each side
61/3.6 ≤ 3.6s/3.6
16.94444 ≤ s
You must make more than 16.94444 sales
But you cannot make part of a sale so
You must make at least 17 sales
