Liono4ka [1.6K]

Answer:

The answer is "0".

Step-by-step explanation:

Please find the correct question in the attached file.

Given value:

\to f(x) =\frac{x^2}{x^2+5}\\\\

Formula:

\bold{\frac{d}{dx} \frac{u}{v} = \frac{ v \frac{du}{dx} - u \frac{dv}{dx}}{v^2}}

\to f'(x) =\frac{(x^2+5) 2x -2x^3 (2x)}{(x^2+5)^2}\\\\\to f'(0) =\frac{(0^2+5)2(0) -4(0)^4}{(0^2+5)^2}\\\\\to f'(0) =\frac{(0)(5) -2(0)}{(5)^2}\\\\\to f'(0) =\frac{0 - 0}{(5)^2}\\\\\to f'(0) =\frac{0}{25}\\\\\to f'(0) = 0

You buy hamburgers at a fast food restaurant. A hamburger costs $0.49. You must have at most $3 to spend. Write an inequality fo
KIM [24]

Answer:

x ≤  6.12

Step-by-step explanation:

If the cost of 1 hamburger in a restaurant is $0.49, the amount of hamburger $3 can buy is expressed as shown .

$0.49 = 1

$3 ≤ x (since you have maximum of $3 to spend. It cant be more than that)

cross multiply to find the expression for x.

$0.49 * x  ≤  $3 * 1

$0.49x  ≤  $3

Divide both sides by $0.49

$0.49x/$0.49  ≤  $3/$0.49

x ≤  $3/$0.49

x ≤  6.12

The number of hamburgers you can buy is represented by the inequality x ≤  6.12
