<span>Las partes más profundas del océano son totalmente desconocidas para nosotros ", admite el profesor Aronnax a principios de esta novela . " Lo que sucede en esas profundidades distantes ? ¿Qué criaturas habitan , o podría habitar, esas regiones doce o quince millas bajo la superficie del agua? Sus casi más allá de conjeturas " . Julio Verne (1828-1905) publicó la traducción en francés de estas palabras en 1869 , y poco ha cambiado desde entonces. 126 años más tarde, un artículo de portada de tiempo en la exploración en aguas profundas hace la misma admisión : " Sabemos más sobre Marte que sabemos sobre los océanos . " Esta realidad comienza a explicar el poder oscuro y la fascinación de otro de los Veinte Mil leguas de viaje submarino</span>

Plz help w this math problem
Svetllana [295]

Answer:

• for x = 2a√t, make t the subject:

{ \tt{x = 2a \sqrt{t} }} \\  \\ { \tt{ \sqrt{t}  =  \frac{x}{2a} }} \\  \\ { \boxed{ \tt{t =  \frac{ {x}^{2} }{4 {a}^{2} } }}}

• then find y:

{ \tt{y =  {ar}^{2}  - 2at}} \\  \\ { \tt{y =  {ar}^{2} - 2a( \frac{ {x}^{2} }{4 {a}^{2} } ) }} \\  \\ { \boxed{ \tt{y =  {ar}^{2} -  \frac{ {x}^{2} }{2a}  }}}

What is the equation of the graph
AveGali [126]

Answer:

y = 2x^2 + 1

Step-by-step explanation:

The graph you see there is called a parabola. The general equation for the graph is as below

y = a*x^2 + b

To find the equation we need to find the constants a and b. The constant b is just how much we're lifting the parabola by. Notice it's lifted by 1 on the y axis.

To find a it's a little more tricky. Let's use the graph to find a value for a by plugging in values we know. We know that b is 1 from the previous step, and we know that when x=1, y=3. Let's use that!

3 = a * (1)^2 + 1\\2 = a

Awesome, we've found both values. And we can write the result.

y = 2x^2 + 1

I'll include a plotted graph with our equation just so you can verify it is indeed the same.
