If f(x) varies directly with x2, and f(x) = 96 when x = 4, find the value of f(2).

Scilla [17]

F ( x ) = k * x²
f ( 4 ) = 96
96 = k * 4²
96 = 16 k
k = 96 : 16
k = 6
f ( 2 ) = 6 * 2² = 6 * 4 = 24
Answer: D ) 24

Suppose F⃗ (x,y)=⟨ex,ey⟩F→(x,y)=⟨ex,ey⟩ and CC is the portion of the ellipse centered at the origin from the point (0,1)(0,1) to

Rudik [331]

Probably the intended ellipse is the one with equation

$\dfrac{x^2}{49}+y^2=1$

We can parameterize $C$ as a piece of this curve by

$\vec r(t)=\langle7\sin t,\cos t\rangle$

with $0\le t\le\frac\pi2$ . Then

$\displaystyle\int_C\vec F\cdot\mathrm d\vec r=\int_0^{\pi/2}\langle e^{7\sin t},e^{\cos t}\rangle\cdot\langle7\cos t,-\sin t\rangle\,\mathrm dt$

etc
