42 - (-25) = 42 + 27 = 69

33 - (-77) = 33 + 77 = 110

44 + (-18) = 44 - 18 = 26

Evaluate the line integral c y3 ds, c.x = t3, y = t, 0 â‰¤ t â‰¤ 3

Temka [501]

$\displaystyle\int_{\mathcal C}y^3\,\mathrm dS=\int_{t=0}^{t=3}t^3\sqrt{1^2+(3t^2)^2}\,\mathrm dt=\int_0^3t^3\sqrt{1+9t^4}\,\mathrm dt$

Take $u=1+9t^4$ so that $\mathrm du=36t^3\,\mathrm dt$ . Then

$\displaystyle\int_{\mathcal C}y^3\,\mathrm dS=\frac1{36}\int_{u=1}^{u=730}\sqrt u\,\mathrm du=\frac{730^{3/2}-1}{54}$

The width of Zorn's patio is labeled in the diagram below. If the perimeter of the patio is (30x + 26) feet, what is the length

Tems11 [23]

We have that
2x²=450 ----------> x²=450/2----------> x=√225
x1=+15
x2=-15

a reasonable length measurement should be positive
therefore

the answer is
The solutions are -15 and 15, but only 15 is a reasonable side length.
