Answer:
4
Step-by-step explanation:
circumference = 2πr
or, 20 = 2π r
or, π r = 10
or, r= 10/π
72 ° = 2π/5
length of arc = r∅ = 10/π × 2π/5
= 4
The answer is 27.1 degrees. because 11.4+15.7 = 27.1.
cos(3x) = cos(2x+x)
= cos(2x) cos (x) -sin(2x)sin(x)








Answer:
23 pets
Step-by-step explanation:
If Susy has 14 dogs and 9 cats she has 23 pets in all.
14 dogs
9 cats
14 dogs + 9 cats = 23 pets
Therefore, Susy has 23 pets.
1 - y = 1.5x - 3
2 - y = 2x - 1
3 - y = 8/3x - 3
4 - y = -3x - 2
5 - y = 5 - 8/5x
6 - y = 5+x/3
