Can't figure out this problem can anyone help if so thank you

Answer:

10th term of the sequence = 0.537

Step-by-step explanation:

First three terms of the sequence are → 5, 4, $\frac{16}{5}$ ..........

Ratio of 2nd and 1st term of the sequence = $\frac{4}{5}$

Ratio of 3rd and 2nd term of the sequence = $\frac{\frac{16}{5} }{4}$

= $\frac{4}{5}$

Therefore, ratio between every successive term to the previous term is common.

Common ratio 'r' = $\frac{4}{5}$

First term of the sequence 'a' = 5

nth term of a geometric sequence = $a(r)^n$

Therefore, nth term of the given term will be $T_n=5(\frac{4}{5})^n$

Now we have to find the 10 term of the given sequence.

For n = 10,

$T_{10}=5(\frac{4}{5})^{10}$

= 0.53687

≈ 0.537

Therefore, 10th term of the sequence is 0.537

Use a linear approximation to estimate the number (125.07)2/3

Ivahew [28]

Let $f(x)=x^{2/3}$ . You have $f(125)=(125)^{2/3}=(5^3)^{2/3}=5^2=25$ .

Taking the derivative, you get

$f'(x)=\dfrac2{3x^{1/3}}\implies f'(125)=\dfrac2{3(125)^{1/3}}=\dfrac2{3\times5}=\dfrac2{15}$

The linear approximation to $f(x)$ near $x=125$ is given by

$L(x)=f(125)+f'(125)(x-125)\approx f(x)$

So the value of $(125.07)^{2/3}$ can be estimated as

$L(125.07)=f(125)+f'(125)(125.07-125)$
$L(125.07)=25+\dfrac2{15}(0.07)=25.009333\ldots$
