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,

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

you spin a spinner numbered from 1 to 6 and spin another spinner with the colors yellow,blue,violet,green, and orange. Both spin

Darya [45]

Answer:

Step-by-step explanation:

Use the fundamental counting principal.

There are 6 possible outcomes on one spinner and 5 possible outcomes on the other spinner. Multiply the possible outcomes together to get the total possible outcomes.

6 x 5 = 30

Find the area of a circle with the radius of 10.

BARSIC [14]

Answer:

about 314.16 units squared

Step-by-step explanation:

The formula for area is A = πr^2. Plugging in r, the radius, we get A = π10^2. Evaluating π*10, we get A = [about] 314.16^2.

If the problem asks you to plug in 3.14 for pi, the answer is 314 units squared.
