Answer:
Sin(460 radians)= .97054
sin(460 degrees)= 0.98480775301
Step-by-step explanation:
I'm not sure where you are from, but usually you are allowed to use a calculator. (At least I was when I took Algebra 2/Trig in 6th grade.)
You never specified radians or degrees so I will answer both.
sin(460 radians)= .97054
sin(460 degrees)= 0.98480775301
If you are not allowed to use a calc, then I suggest looking at unit circle videos on Khan Academy.
Answer:
12
Step-by-step explanation:
h(n)=3n
h(4)
1. Subsitute 4 for n
h(4)=3*4
h(4)=12
Check the picture below.
notice the alternate interior angles in the picture.

A number is divisible by two if you get no remainder when you divide that number by two. Even numbers are divisible by two. Odd numbers are not divisible by two.
