I am Lyosha [343]

Answer:

Step-by-step explanation:

$f(x) = \frac{3}{x + 2} - \sqrt{x - 3} \\$

To find f(19) , substitute the value of x that's 19 into f(x). That is for every x in f (x) replace it with 19

We have

$f(19) = \frac{3}{19 + 2} - \sqrt{19 - 3} \\ = \frac{3}{21} - \sqrt{16} \\ = \frac{1}{7} - 4 = \frac{1 - 28}{7}$

We have the final answer as

$f(19) = - \frac{27}{7} \\$

Hope this helps you

Find the geometric sum: 40 + 20 + 10 + … + 0.078125

sveticcg [70]

$S=40+20+10+\cdots+0.078125$
$S=40\left(1+\dfrac12+\dfrac14+\cdots+\dfrac1{512}\right)$
$S=40\left(1+2^{-1}+2^{-2}+\cdots+2^{-9}\right)$

$2^{-1}S=40\left(2^{-1}+2^{-2}+2^{-3}+\cdots+2^{-10}\right)$

$\implies S-2^{-1}S=40\left(1-2^{-10}\right)$
$\implies\dfrac12S=40\left(1-\dfrac1{1024}\right)$
$\implies S=80\left(1-\dfrac1{1024}\right)=\dfrac{5115}{64}=79.921875$
