3/8 cross multiply x/800 8x and 2400 divide both sides by 8 to get 300. 300 is the answer

Is √6/8. rational or irrational?

Ipatiy [6.2K]

<h2>Answer:</h2>

The number is irrational.

<h2>Step-by-step explanation:</h2>

<h3>1. Convert to decimal.</h3>

$\sqrt{\frac{6}{8} } =\sqrt{0.75} =0.8660254038...$

<h3>2. Conclude.</h3>

Since this number shows to have infinite decimal figures, it cannot be represented as the ratio of 2 integers. Hence, the number is irrational.

-------------------------------------------------------------------------------------------------------

Note. In case the number expressed in the question was $\frac{\sqrt{6} }{8}$ , the answer would still be irrational, for the same reasons explained above.

Consider f and c below. f(x, y) = (7 + 8xy2)i + 8x2yj, c is the arc of the hyperbola y = 1/x from (1, 1) to 3, 1 3 (a) find a fu

KonstantinChe [14]

$\dfrac{\partial f}{\partial x}=7+8xy^2$

$\dfrac{\partial f}{\partial y}=8x^2y$

The first equation gives

$f(x,y)=7x+4x^2y^2+g(y)$

Differentiating with respect to $y$ gives

$8x^2=8x^2y+\dfrac{\mathrm dg}{\mathrm dy}\implies\dfrac{\mathrm dg}{\mathrm dy}=0\implies g(y)=K$

for some constant $K$ . So

$f(x,y)=7x+4x^2y^2+K$

and by the fundamental theorem of calculus,

$\displaystyle\int_C\nabla f\cdot\mathrm d\vec r=f\left(3,\frac13\right)-f(1,1)=25-11=\boxed{14}$
