Answer:
26
Step-by-step explanation:
Use the Pythagorean Theorem: ![a^2+b^2=c^2](https://tex.z-dn.net/?f=a%5E2%2Bb%5E2%3Dc%5E2)
Its very easy
455 means 5*7*13
now divide (5*7*13) by 7
you will easily get 5*13=65
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 ![\sqrt{9}= 3](https://tex.z-dn.net/?f=%5Csqrt%7B9%7D%3D%203)
The formular for this is
∑![\frac{1}{n^p} \\](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bn%5Ep%7D%20%5C%5C)
where n = 1
we know it is convergent because p is greater than 1. 3>1

Lets Anna's age = A
Mr. Goldstein age = G
Mr. Goldstein is 4 times as old as his daughter Anna.
So G= 4A
In 4 years, he will be 3 times as old as Anna
we add 4 with Both their ages
G + 4 = three times of A + 4
G + 4= 3(A + 4)
We know G= 4A, replace it in above equation
4A + 4= 3(A + 4)
4A + 4= 3A + 12
Subtract 3A from both sides
A + 4 = 12
Subtract 4 from both sides
A = 8
So Anna's age = 8 years
