Answer:
cos ∅ = 15/17
Step-by-step explanation:
hypotenuse² = 15² +8² = 225 + 64 = 289
hypotenuse = √289 = 17
cos ∅ = 15/17 =
Answer:
1/49
Step-by-step explanation:
Y-axis symmetry=(r, theta)=(-r,theta)
-5-5cos(theta)=r
-r=5+5cos(theta)
no y-axis symmetry
x-axis symmetry=(r,theta)=(r,-theta)
cosine is an even function, so yes it is symmetric around x-axis
origin symmetry=(r,theta)=(-r,theta) or (r, theta+pi)
no, as there is no y-axis symmetry
Suppose the integers are n , n+2 , n+4 and n+6.
84=n+(n+2)+(n+4)+(n+6)=4n+12.
Subtract 12 from both ends to get.
72=4n.
Divide both ends by 4 to get.
n=18.
So the integers are: 18 , 20 , 22 , 24.
5 milligrams are equal to .005 grams.
