Square root of 164 is 12.8062485, so each side is around 12.8 inches.
(if you have multiple choice then hopefully there is an answer like this XD)

Hope i helped :)

the length of a side of a square is the square root of the area

side length = sqrt(164)

side length = 12.8062

Round the answer as needed

since it asks for approximate, it is probably going to be 13 inches

Write a recursive formula and an explicit formula for the following arithmetic sequence: -1,6,13,20,27

Luden [163]

Answer:

Recursive formula is: $a_1=-1 ; \ \ a_n=a_{n-1}+7$

Explicit formula is: $a_n=7n-8$

Step-by-step explanation:

We need to find recursive formula and explicit formula for arithmetic sequence -1,6,13,20,27

In the given sequence First term a₁= -1

Common difference d = 7

Finding Recursive Formula

The recursive formula is of type: $a_1= First \ term$ and $a_n=a_{n-1}+d$

Since the First term a₁ is -1 and common difference d is 7 so, the recursive formula for given arithmetic sequence will be:

$a_1=-1 ; \ \ a_n=a_{n-1}+7$

Finding Explicit Formula

The explicit formula is of type: $a_n=a_1+(n-1)d$

We have

First term a₁= -1

Common difference d = 7

So, explicit formula will be:

$a_n=-1+(n-1)7\\a_n=-1+7n-7\\a_n=7n-8$

So, explicit formula is: $a_n=7n-8$

If a polynomial function f(x) has roots 0, 4, and 3 + StartRoot 11 EndRoot, what must also be a root of f(x)? 3 + i StartRoot 11

serg [7]

Answer:

3 − √11

Step-by-step explanation:

For polynomials with rational coefficients, any radical roots must come in conjugate pairs. To find the conjugate, simply reverse the sign of the radical.
