Answer:

Step-by-step explanation:
Since you are doing
squared, you have to multiply the exponents.
4 * 2 = 8

Answer:1/30 page per minute
Step-by-step explanation:
2 1/2 pages =3/2 pages.
3/4 hrs=45 minutes
Hence the number pages he can type per minute =3/2 pages/45 minutes=3/2×1/45=1/30page per minute
Answer:
48
Step-by-step explanation:
The mean of a number is the sum of all the numbers divided by how many numbers there are. We can set up this formula:
.
When we plug our values into this equation, we get:
. Solving this equation gets us sum = 6 * 8 = 48
If n is an integer, then cos(n(2<span>π))=1.
Take n=0, cos(2</span>π)=cos(0)=1, n=1, cos(2π)=1, n=2, cos(2(2π))=cos(4<span>π)=cos(0)=1...
If n is not an integer, well, ..... we don't know the value, which depends on the value of n.</span>
