notka56 [123]

Answer:

Square Root of 40 to the Nearest Tenth

Square Root to the nearest tenth

Square Root of 40 to the nearest tenth, means to calculate the square root of 40 where the answer should only have one number after the decimal point.

Here are step-by-step instructions for how to get the square root of 40 to the nearest tenth:

Step 1: Calculate

We calculate the square root of 40 to be:

√40 = 6.32455532033676

Step 2: Reduce

Reduce the tail of the answer above to two numbers after the decimal point:

6.32

Step 3: Round

Round 6.32 so you only have one digit after the decimal point to get the answer:

6.3

To check that the answer is correct, use your calculator to confirm that 6.32 is about 40.

Given the below sequence:

kvasek [131]

Answer:

a) The next three terms are -1,-3,-5,-7,-9,-11,-13

b) This is arithmetic sequence

C) The difference of second term and first term is -2 in given sequence so the given sequence is an arithmetic sequence.

d) The 27 th term is -53

Step-by-step explanation:

a) the given sequence is arithmetic sequence

the difference of second term and first term is -2

given sequence is -1,-3,-5,-7.....

the nth term in arithmetic sequence

$t_{n} = a+(n-1)d$

First term is a = -1 and difference is d = -2

finding fifth term is

$t_{5} = -1 +(5-1)(-2)$

$t_{5} = -1-8 =-9$

finding sixth term is

$t_{6} = -1 +(6-1)(-2)$

$t_{6} = -1-10 =-11$

finding seventh term is

$t_{7} = -1 + (7-1)(-2)$

$t_{7} = -1 -12 =-13$

The next three terms are -9,-11,-13

The given sequence is -1,-3,-5,-7,-9,-11,-13

b) This is arithmetic sequence.

C) because the difference of second term and first term is -2 so the given sequence is arithmetic sequence.

d) by using nth term formula in arithmetic sequence

$t_{n} = a+(n-1)d$

a= -1 and d =-2

find 27 t h term :-

$t_{27} = -1 + (27-1)(-2) = -1-52=-53$
