Find f/g for the functions provided. 10 points Help needed.

-BARSIC- [3]

ANSWER

$( \frac{f}{g} )(x) = \frac{1}{3} ( {x}^{2} + 3x + 9)$

EXPLANATION

The given functions are

$f(x) = {x}^{3} - 27$

and

$g(x) = 3x - 9$

$( \frac{f}{g} )(x) = \frac{f(x)}{g(x)}$

$( \frac{f}{g} )(x) = \frac{ {x}^{3} - 27}{3x - 9}$

$( \frac{f}{g} )(x) = \frac{ (x - 3)( {x}^{2} + 3x + 9) }{3(x -3 )}$

Cancel the common factors,

$( \frac{f}{g} )(x) = \frac{ {x}^{2} + 3x + 9 }{3}$

$( \frac{f}{g} )(x) = \frac{1}{3} ( {x}^{2} + 3x + 9)$

Please help I have no clue what this is I give brainly :)

196 + x = 500

Subtract 196 from both sides:
196 on the left is cancelled out, and you’re left with x = 304

Given: △FKL, FK=a, m∠F=45°, m∠L=30° Find: FL

drek231 [11]

The best way to do this is to draw a picture of ΔFKL and include line segment KM that is perpendicular to FL. This creates ΔFKM which is a 45°-45°-90° triangle and ΔLKM which is a 30°-60°-90° triangle.

Find the lengths of FM and ML. Then, FM + ML = FL

FM

ΔFKM (45°-45°-90°): FK is the hypotenuse so FM = $\frac{a}{\sqrt{2}} = \frac{a\sqrt{2} }{2}$

ML

ΔLKM (30°-60°-90°): from ΔFKM, we know that KM = $\frac{a\sqrt{2} }{2}$ , so KL = $\frac{a}{\sqrt{6}} = \frac{a\sqrt{6} }{6}$

FM + ML = FL

$(\frac{3}{3})\frac{a\sqrt{2} }{2} + \frac{a\sqrt{6} }{6}$

= $\frac{3a\sqrt{2} + a\sqrt{6} }{6}$

A shopper paid$67.36 including tax for an item marked $62.95. What should she pay for another item marked $82?

Jlenok [28]

Answer:

153.77

Step-by-step explanation:

First, you subtract the item's original price from the price with tax. Then, you use the tax price from the subtraction, (your answer) and add it to the 82$. Last, add the $67.36 with $86.41 (the tax added to the $82) and you will get your answer, $153.77
