What is the difference between infinity and forever?

VikaD [51]

When you say something goes on forever, it means that it is going on to infinity. Infinity is something that can be used as a mathematical concept, but forever is not. Forever is something people say if they don't know how infinity is used.

Find all values of m so that the function y = xm is a solution of the given differential equation. (Enter your answers as a comm

blagie [28]

Answer:

m = 6,9

Step-by-step explanation:

We are given that $y = x^m$ is a solution to given differential equation.

$x^2y'' - 14xy' + 54y = 0$

First we 3evaluate the value of:

$y'' = m(m-1)x^{(m-2)}$

$y' = mx^{(m-1)}$

Putting these value in the above differential equation, we get,

$x^2m(m-1)x^{(m-2)} + 14xmx^{(m-1)} + 54x^m = 0$

$x^m[m(m-1) -14m + 54] = 0$

$x^m(m^2 - 15m + 54) = 0$

$(m^2 - 15m + 54) = 0$

$(m-9)(m-6) = 0$

$m = 9,6$

Thus, for m = 9,6 , the function $y = x^m$ is a solution of given differential equation.

Steps to finding the line in the diagram with the format 'ax + by = c

1. Find the slope

To find the slope, we need any two points on the line --> (0,4) and (3,0)

$Slope = \frac{y2-y1}{x2-x1} =\frac{4-0}{0-3} =-\frac{4}{3}$

2. Set up, with any one point on the line and the slope, in point-slope form

$(y-y0)=m(x-x0)\\(y-4)=-\frac{4}{3} (x-0)\\y-4 = -\frac{4}{3} x\\\frac{4}{3}x+y = 4$

<u>Answer</u>: $\frac{4}{3}x+y = 4$

Hope that helps!

More help, im still confused

nevsk [136]

Answer:

a) $\frac{1}{3}$

b) $\frac{4}{5}$

Step-by-step explanation:

a) the exponent is 2, therefore the value of $\sqrt[2]{9}$ would go in the place of the base.

b) the exponent is 2, therefore the value of $\sqrt[2]{\frac{16}{25} }$ would go in the place of the base => $\frac{\sqrt{16}}{\sqrt{25}}$ = $\frac{4}{5}$
