The answer is: 2 + (6 * y)

Why?

It's asking for 2 more than, which is generally 2 +, the product, which signifies multiplication, of 6 and y, the numbers that are being multiplied.

Put all those terms together, you end up getting 2 + (6 * y).

Parameterize the path $\mathcal C$ by

$\mathbf r(t)=x(t)\,\mathbf i+y(t)\,\mathbf j$

with

$x(t)=3\cos t$
$y(t)=3\sin t$

and $0\le t\le\pi$ . Then

$\displaystyle\int_{\mathcal C}\mathbf f(x,y)\cdot\mathrm d\mathbf r=\int_{t=0}^{t=\pi}\mathbf f(x(t),y(t))\cdot\dfrac{\mathrm d\mathbf r}{\mathrm dt}\,\mathrm dt$
$=\displaystyle\int_0^\pi(9\cos^2t\,\mathbf i+9\sin^2t\,\mathbf j)\cdot(-3\sin t\,\mathbf i+3\cos t\,\mathbf j)\,\mathrm dt$
$=27\displaystyle\int_0^\pi(\cos t\sin^2t-\sin t\cos^2t)\,\mathrm dt=-18$

How do I do this I really need to know!

Nostrana [21]

Answer:

Step-by-step explanation:

I'm doing seven.

x = -2

y = 2^(-2 -1) + 2

y = 2^(-3) + 2

y = 1/2^3 + 2

y = 1/8 + 2

y = 2.125 which is a guess on the graph.

x = - 1

y = (2)^(-1 -1) + 2

y = (2)^-2 + 2

y = 1/4 + 2

y = 2.25

x = 0

y = 2^(0 - 1) + 2

y = 2^(-1) + 2

y = 1/2 + 2

y = 2.5

x = 1

y = 2^(1 - 1) + 2

y = 2^0 + 2 If the power of a number = 0 then the result = 1. The only exception to that is 0^0

y = 1 + 2

y = 3

Eight

x = -1

y = (1/2)^(-1 + 1) + 2

y = 1 + 2

y = 3

x = 0

y = (1/2)^(0 - 1) + 2

y = (1/2)^-1 + 2 Turn the 1/2 upside down

y = 2 + 2

y = 4

x = 1

y = (1/2)^(1 + 1) + 2

y = (1/2)^2 + 2

y = 1/4 + 2

y = 2.25

x = 2

y = (1/2)^(2 + 1) + 2

y = (1/2)^3 + 2

y = 1/8 + 2

y = 2.125
