1 hour = 3,600 seconds and 1 mile = 5,280 feet. Make a conjecture about how you could convert a speed of 15 miles per hour to fe
MrRissso [65]

Answer:

  multiply by feet per mile and divide by seconds per hour

Step-by-step explanation:

To get the desired units, multiply by a factor that is equal to 1, but has the desired units in the numerator and the units you're converting from in the denominator.

For units in the denominator that you want to change, use the inverse of the above multiplier.

We have miles/hour, which has miles in the numerator. We want feet/second, which has feet in the numerator, so we need to multiply by the ratio of feet per mile: 5280 ft/mi.

We also have hours in the denominator, where we want seconds. So, we divide by the factor 3600 s/h.

  \dfrac{15\,\text{mi}}{\text{h}}\cdot\dfrac{5280\,\text{ft}}{\text{mi}}\cdot\dfrac{\text{h}}{3600\,\text{s}}=22\,\text{ft/s}

3. Problema 2: Suponga que un fabricante de radios tiene la función de costo total C (x) = 43x + 1850 dólares y la función de in
allochka39001 [22]

Responder:

$ 11,137

Explicación paso a paso:

Como no se nos dice qué encontrar, también podemos encontrar el beneficio obtenido por la venta de 351 unidades de radio.

Dado

Función de costo C (x) = 43x + 1850

Función de ingresos R (x) = 80x

Obtener la función de ganancias

P (x) = R (x) - C (x)

P (x) = 80x - (43x + 1850)

P (x) = 80x - 43x - 1850

P (x) = 37x - 1850

Si se fabrican 351 radios, la ganancia obtenida se calculará como se muestra a continuación:

P (351) = 37 (351) - 1850

P (351) = 12,987-1850

P (351) = 11,137

<em>Por lo tanto, la ganancia obtenida de las ventas de 351 radios es de $ 11,137</em>
