If your PCR product size was 172 and there were 130 base pairs next to a 14 base pair repeat, then there are 3 repeats.
Given that the newly used primer amplifies 130 base pairs that are near
(a) 14 base pair and
(b) the size of the pcr product is 172
Size = (number of base pairs * number of repetitions) + Initial/Primer Amplicon Value
172 = (14 * x) + 130
172 -130 = 14x
42 = 14x
3 = x
Therefore, we can say that the PCR product has 3 repeats.

Answer: The answer is D
Step-by-step explanation:
If you read all the answers only D is true
The Pythagorean theorem formula for a triangle is A^2 + B^2 = C^2 where A and B are the sides and C is the hypotenuse.
The sides of the triangle shown are AB and BC and the hypotenuse is AC,
so the correct answer would be:
(AB)2 + (BC)2 = (AC)2, because 25 + 144 = 169
Using FOIL (First, Outer, Inner, Last):
(x+3)(x-4)
FIRST: multiply x times x to get x^2.
OUTER: multiply x times -4 to get -4x.
INNER: multiply 3 times x to get 3x.
LAST: multiply 3 times -4 to get -12.
Your expression now looks like:
x^2-4x+3x-12
Combine like terms.
x^2-x-12
The answer is D. x^2-x-12.
I hope this helps :)
Answer:
OPTION B
Step-by-step explanation:
Geometric series : 
where 
is the first term of the series and
is common difference.
A geometric series is convergent if |r| < 1.
It is divergent otherwise.
Since the first term of the series is a and the second term is ar, the ration of second term and first term, 
= r.
OPTION A:
.
Here, 
and 
r > 1. So, this series is divergent.
OPTION B:
a = 1; ar = 
.
.
Since, r < 1, we can say that the series is convergent.
OPTION C:
We can easily see that |r| =4. So, it is not convergent.
OPTION D:
Again |r| = 2. So, the series should be divergent.
