Each week he earns $142.5 from his partime job plus $25 from chores and then saves 85% of that total ($167.5). 85x167.5 = 14237.5 divided by 100 = 142.375 which is 85% of what he earns each week. Then multiply that by 8 weeks to find his total on August 25th. The answer should be $1,139

Answer:

D. $x^{-3/2}$

Step-by-step explanation:

<u>Given function:</u>

$f(x) = \frac{1}{x\sqrt{x} }$

<u>Equivalent expression is:</u>

$\frac{1}{x\sqrt{x} } = x^{-1}x^{-1/2} = x^{-1 - 1/2} = x^{-3/2}$

PLS HELP<br><br> f(x)=x^3−2x^2+12x−6<br><br> g(x)=4x^2−6x+4<br><br> What is (f−g)(x)?

vodomira [7]

Answer:

$(f - g)(x) = {x}^{3} - 6 {x}^{2} + 18x - 10$

Step-by-step explanation:

The given functions are:

$f(x) = {x}^{3} - 2 {x}^{2} + 12x - 6$

and

$g(x) = 4 {x}^{2} - 6x + 4$

We want to find

$(f - g)(x)$

Recall that:

$(f - g)(x) = f(x) - g(x)$

This implies that:

$(f - g)(x) = {x}^{3} - 2 {x}^{2} + 12x - 6 - (4 {x}^{2} - 6x + 4)$

$(f - g)(x) = {x}^{3} - 2 {x}^{2} + 12x - 6 - 4 {x}^{2} + 6x - 4$

We combine similar terms to get:

$(f - g)(x) = {x}^{3} - 6 {x}^{2} + 18x - 10$
