I don't really understand pls help asap
maria [59]

Answer:

It is not proportional

Step-by-step explanation:

    To figure out if something is proportional they have to equal the same thing.

   As you can see on the problem 0.2 and 0.2 are the same thing, and since one is on the numerator and one is on the demoninator those two can cross out.

    Now we come to the 0.08 and the 0.8.

     They are not the same thing the 0.08 has an extra 0.

So this is not proportional

Answer:

30 hrs

Step-by-step explanation:

Downstream. In water, the direction along the stream is called downstream.

Upstream. In water, the direction against the stream is called upstream. Let the speed of a boat in still water be u km/hr and the speed of the stream be v km/hr, then. Speed downstream = (u + v) km/hr. Speed upstream = (u - v) km/hr

Determine the region of the xy-plane where the solution of the DE would have a unique solution passing through the point (x0,y0)
Virty [35]

Answer:

given equation,

(9-y^2)\dfrac{dy}{dx}= x^4\\(9-y^2)dy = x^4 dx\\\int (9-y^2)dy =\int x^4 dx\\9y -\dfrac{y^3}{3} = \dfrac{x^5}{5}+C

so,

the given point from where the region is passing through is (x₀, y₀)

hence, the unique equation comes out to be

9y_0 -\dfrac{y_0^3}{3} = \dfrac{x_0^5}{5}+C

C = 9y_0 -\dfrac{y_0^3}{3}-\dfrac{x_0^5}{5}

hence unique equation,

9y -\dfrac{y^3}{3} = \dfrac{x^5}{5}+ 9y_0 -\dfrac{y_0^3}{3}-\dfrac{x_0^5}{5}
