Answer:
Option D
Step-by-step explanation:
- You have to first find 4^x and then multiply it with two .
Not like this
(×)
Hence the variable has coefficient 4 as 4^x is multiplied.
C. 480
Explanation: I’m pretty sure you’re looking for the perimeter. Therefore, since you have a rectangle, you’ll have 4 sides. The measures are 100 by 140 so you’ll put 100 and 140 on the other sides and simply add them up.
To solve that question we can think by the following way:
- The first letter can be any of the letters (A, C, T or G). Therefore there are 4 possibilites.
- To choose the second letter of the sequence, any letter also can be chose. So, one more time, there are 4 possibilites.
Using the fundamental principle of counting, we will find out that can be formed differents sequences (for example, AA, AG, TT, TG, CT...).
Know we know that, we can generalize. If I have elements and I must choose one of them times to do a sequence, the total number of sequence that I can form will be .
In our question, we want to know how many DNA sequence are exactly 29 letters long. As indicated above, the answer for that is (29 times) .
Therefore, there are DNA sequences with exactly 29 letters long.

Answer:
The function will be: f(n) = 2n
Step-by-step explanation:
An arithmetic sequence is a sequence where the common difference between consecutive terms is same
The sequence according to given information is:
2,4,6...
Here
a_1 = 2
a_2 = 4
a_3 = 6
the common difference will be:
The arithmetic sequence is given by:
Putting the values
Hence,
The function will be: f(n) = 2n
