Find the point below that lies on the line y-7=4(x-2)
Phantasy [73]

Step-by-step explanation:

y-7=4(x-2)

we need to simplify the y to het a

y-7=4x-8 (i did 4x-8 because of 4(x-2)

now y= 4x-8+(-7)

after calculating -8+(-7) IT becomes

y=4x-15

okay we have the guide Line

y=4x-15

the a is 4

because

a = {y=a.x+b}

now we need to find the points using this guide Line

y=4x-15

x= 2(you can add any number here ,we Just need to know where the point is )

y= 4(2)-15

y=8-15

y= -7

points are (2,7)

Crecimiento de arboles
denpristay [2]

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.
