Crecimiento de arboles

Mathematics

Queremos encontrar la altura de las plantas luego de t años, dado que conocemos la altura inicial y la velocidad de crecimiento.

La ecuación de la altura es:

h(t) = 0.75*t^2 + 5*t + 12

Con ella veremos que los arbustos miden 69cm cuando son vendidos.

<em>Veamos como resolver esto.</em>

h(t) es la función que modela la altura de las plantas.

Sabemos que:

\frac{dh(t)}{dt} = 1.5*t + 5

Sí integramos, obtendremos:

h(t) = (1/2)*1.5*t^2 + 5*t + c

donde C es una constante de integración, la cual representa la altura inicial (para t = 0) de las plantas, notar que:

h(0) = c

Y sabemos que las plantas miden 12 cm cuando son plantadas, entonces c = 12.

La ecuación de la altura es entonces:

h(t) = 0.75*t^2 + 5*t + 12

Esta ecuación nos da la altura en centimetros a tiempo t.

Sabemos que los arbustos se venden luego de 6 años, entonces la altura que tendran cuando son vendidos es:

h(6) = 0.75*6^2 + 5*6 + 12 = 69

Es decir, los arbustos miden 69cm cuando son vendidos.

Three times a larger number is 30 more than 5 times a smaller number. The sum of the larger number and 5 times the smaller numbe
slava [35]
3y  = 5x + 30

y + 5x = 50 .......(1)

3y - 5x = 30 .....(2)        - rearranging the first equation.

Add (1) and (2):-

4y = 80

y = 20  
Now plug y = 20 into equation (1):-
20 + 5x = 50
5x = 30 
x = 6

The 2 numbers are 6 and 20.
