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, $x=20$ ,

Can someone help me plzzzz

PSYCHO15rus [73]

Answer:

279 feet

Step-by-step explanation:

To find x, we solve using the Trigonometric function of Tangent

tan θ = Opposite/ Adjacent

θ = 64°

Length of the shadow = Adjacent = 136 feet

Height of the building = Opposite = h

Hence,

tan 64 = h/136 feet

Cross Multiply

h = tan 64 × 136 feet

h = 278.84132245 feet

Approximately, h to the nearest foot ≈ 279 feet

Therefore, the height of the building = 279 feet

Given a point A(-3,-1), it is dilated by some scale

Sidana [21]

Answer:

$B' = (-3, -15)$

Step-by-step explanation:

Given

$A = (-3,-1)$

$A' = (-9,-3)$

$B = (-1,-5)$

Required

Determine the coordinates of B'

Since A' is the image of A; we need to first calculate the scale factor using

$A' = A * Scale\ factor$

Make Scale Factor the subject

$Scale\ Factor = \frac{A'}{A}$

Substitute values for A' and A

$Scale\ Factor = \frac{(-9,-3)}{(-3, -1)}$

Factorize the numerator

$Scale\ Factor = \frac{3 * (-3,-1)}{(-3, -1)}$

$Scale\ Factor = \frac{3 * 1}{1}$

$Scale\ Factor = 3$

The coordinates of B' is then calculated as follows:

$B' = B * Scale\ Factor$

Substitute values for B and Scale Factor

$B' = (-1,-5) * 3$

$B' = (-3, -15)$

Given vectors u and v, with u = 10 and v = 12, and the angle between the vectors is 53°, what is u v?

Sergio039 [100]

Answer:

So we can compute the angle θ between u and v using the dot product: θ = arccos ( u · v u v ) . u · v = u vcos(0) = u v > 0. , so u · v = u vcos(π/2) = 0.
