Answer:
D
Step-by-step explanation:
a perfect square trinomial is
factorized is
so as you can see option A and B can't be, because they have -49y^2 and it has to be plus
so the other options are C and D
in the trinomial a=4 and b=\pm 7
the roots of a^2 and b^2
so it's option d with b=-7
The series is a convergent p-series with p = 3
<h3>How to know it is a divergent or a convergent series</h3>We would know that a series is a convergent p series when we have ∑ 1 np. Then you have to be able to tell if the series is a divergent p series or it is a convergent p series.
The way that you are able to tell this is if the terms of the series do not approach towards 0. Now when the value of p is greater than 1 then you would be able to tell that the series is a convergent series.
The value of
The formular for this is
∑
where n = 1
we know it is convergent because p is greater than 1. 3>1
