trapecia [35]

Answer:

Yes

Step-by-step explanation:

Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8. and that is something Very similar.

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,

16 m, 21 m, 39 m in geometry tryna find out how to measure the side length that could form a triangle
Lera25 [3.4K]

Step-by-step explanation:

The given measurements are:

16 m, 21 m, 39 m

We know that, it is only possible to form a triangle if sum of the measures of any two lengths is always grater than the measure of third length.

\therefore \: 39 + 21 = 60 > 16 \\  \\  \:  \:  \:  \:  \:  \: 16 + 39 = 55 > 21 \\  \\  \:  \:  \:  \:  \:  \: 16 + 21 = 37   \ngtr39 \\  \\  \because \: last  \: mathematical\: statement \: is  \:\\ defying \: the \: above \: law \\

Therefore, it is not possible to form a triangle with given measurements.
