3.1415... is not a rational number because it is continuous.

Hope I helped :)

Ratinonal numbers can repeat as long we can see the repeating part with a line over it (called a vinculum)
rational numbers can be written in form a/b where b is not equal zero

1.33333333333333 is repeating, it is 4/3

3.1415... is obviously an attempt to represent pi or π, the most famous irrational number

5.25 is easy, 5.25/1 or 525/100

0.6666666666666=2/3

the answer is 3.141592...

Solve 8[7-(6x-6)]+6x=0

bazaltina [42]

8[7 - (6x - 6)] + 6x = 0

8[7 - 6x + 6] + 6x = 0

56 - 48x + 48 + 6x = 0

104 - 42x = 0 .

- 42x = - 104 .

x = 52 / 21

x ≈ 2.476

Consider f and c below. f(x, y) = x2 i + y2 j c is the arc of the parabola y = 2x2 from (−1, 2) to (1, 2) (a) find a function f

Korvikt [17]

If there is some scalar function $f(x,y)$ such that

$\nabla f(x,y)=\mathbf f(x,y)=x^2\,\mathbf i+y^2\,\mathbf j$

then we want to find $f$ such that

$\dfrac{\partial f}{\partial x}=x^2\implies f(x,y)=\dfrac{x^3}3+g(y)$
$\dfrac{\partial f}{\partial y}=y^2=\dfrac{\mathrm dg}{\mathrm dy}\implies g(y)=\dfrac{y^3}3+C$
$\implies f(x,y)=\dfrac{x^3}3+\dfrac{y^3}3+C$

So the vector field $\mathbf f(x,y)$ is conservative, which means the fundamental theorem applies; the line integral of $\mathbf f$ along any path $\mathcal C$ parameterized by some vector-valued function $\mathbf r(t)$ over $a\le t\le b$ is given by

$\displaystyle\int_{\mathcal C}\mathbf f\cdot\mathrm d\mathbf r=\int_{t=a}^{t=b}\mathbf f(\mathbf r(t))\cdot\dfrac{\mathrm d\mathbf r}{\mathrm dt}\,\mathrm dt=f(\mathbf r(b))-f(\mathbf r(a))$

In this case,

$\displaystyle\int_{\mathcal C}\mathbf f\cdot\mathrm d\mathbf r=f(1,2)-f(-1,2)=\dfrac23$
