This equation shows how the total cost of visiting the science museum as a member is related to the number of visits. c = 9.8v +

LiRa [457]

Well it's giving you what the cost is (42.3), so plug that in for $c$ :

$42.3 = 9.8v + 22.7$

And now you need to solve for the number of visits ( $v$ )!

$19.6 = 9.8v$

$v=2$

So you can visit the museum a maximum of 2 times!

$\displaystyle\int_0^5\int_x^5\sin(y^2)\,\mathrm dy\,\mathrm dx$

The integration region is the triangle in the $x,y$ plane bounded by the lines $y=5$ , $y=x$ , and $x=0$ . Reversing the order of integration, this is equal to
