Answer:

First statement is correct.

Step-by-step explanation:

In the first statement,

in the left hand side, 10 has -3 as its power but in the right hand side +3 is the 10's power.

$2.06 \times 1.88 = 3.8728 \\\frac{7.69}{2.3} = 3.3435$

According to 10's power, left hand side < right hand side.

Hence, there is no need to check the other statements.

Urgent please help..

The answer is 51.3

Explanation:
You’re finding angle Y, so write the SOH CAH TOA. the two sides your are given are the adjacent side to Y and the opposite side so you use tangent. You then get the equation tanY=10/8 Since you’re finding an angle you use inverse tangent so you get y=tan^-1(10/8) and then put that into the calculator!

Find an expression for the nth term (t_n) in each of the following

Serhud [2]

<h3><u>Answer:</u></h3>

$\boxed{\pink{\tt\longmapsto The \ nth \ term \ of \ the \ sequence\ is \ given \ by \frac{1}{n}}}$

<h3><u>Step-by-step explanation:</u></h3>

A sequence is given to us is , and we need to find expression for nth term of the sequence. The given sequence is ,

$\boxed{\boxed{\blue{\qquad\bf 1 , \dfrac{1}{2},\dfrac{1}{3},\dfrac{1}{4},\dfrac{1}{5},\dfrac{1}{6}}}}$

When we flip the numbers , we can clearly see that the number are in Harmonic Progression.

That is when we flip the numbers they are found to be in Arithmetic Progression .

And nth term of an Harmonic Progression is :-

$\boxed{\purple{\bf T_{(Harmonic \ Progression)} = \dfrac{1}{a+(n-1)d}}}$

Hence here

Common difference = 1
First term = 1 .

<u>Substituting the respective values,</u>

$\bf\implies T_{n}= \dfrac{1}{a+(n-1)d} \\\\\bf\implies T_{n} = \dfrac{1}{1+(n-1)1}\\\\\bf\implies T_n = \dfrac{1}{1+n-1}\\\\\bf\implies\boxed{\red{\bf T_{n}=\dfrac{1}{n}}}$

<h3><u>Hence the nth term of the given sequence is given by ¹/n .</u></h3>
