La funcion que representa el beneficio obtenido por una empresa si vende x unidades de uno de sus productos es f(x)= -70x^2+2800

DerKrebs [107]

Answer:

$20$

Step-by-step explanation:

La función es

$f(x)=-70x^2+2800x-45000$

Diferenciando con respecto a $x$ obtenemos

$f'(x)=-140x+2800$

Igualar con cero

$0=-140x+2800\\\Rightarrow x=\dfrac{2800}{140}\\\Rightarrow x=20$

Doble derivada de la función

$f''(x)=-140$

Entonces, la función es máxima cuando el número de unidades vendidas, $x=20$ ,

A total of $3800 is invested into two accounts paying 4% and 7% annual interest. In one year the combined interest on the accoun

Sedaia [141]

To find the money you make, take:

x(1 (+ or -) % interest rate) * Time

So in this case, it would be:

3800(1+0.04)(1) = Ans
and
3800(1+0.07)(1) = Ans

Assumably, combining those totals would give you $218. If you take the total of 3800(1+0.04)(1), subtract that from $218.

218 - (3800(1+0.04)(1)) = Your Answer

To travel 100 miles,

1/35 * 100

= 0.0286 * 100

= 2.86 gallons

Therefore, the car needs 2.86 gallons of gas to travel 100 miles
