Answer:
131.95
Step-by-step explanation:
C=2πr=2·π·21≈131.94689
1. The domain of the sequence shown is {1, 2, 3, 4, 5}. This is best matched by the description Natural numbers.
2. The common ratio is 3/1 = 9/3 = 3.
3. The first term of this geometric sequence is 1. The common ratio is 3. So, the explicit formula is f(x) = 1(3)^(x-1)
Answer:
The factor form is:

Step-by-step explanation:
Here we have to find the factor of the expression:

So we need to take out the common terms, as we do for finding the greatest common factors.
Now the expression that is given can be re-written as:

Next, we will find the common terms, as follows;

Now we will factorise the expression:

as follows;

So the final factor form is:

Perimeter = 2*(L + W) = 2*(12 + 5) = 2*17 = 34
Perimeter = 34 m
Option D.
45*6 = 270
280-270 = 10
45 can go into 280 , only 6 times, and their is a remainder of 10.
