Let c be parametrized by x = et sin (10t) and y = et cos (10t) for 0 ≤ t ≤ 2. find the length l of

marysya [2.9K]

$C:x(t)=e^t\sin10t;\,y(t)=e^t\cos10t;\,0\le t\le2$

$\displaystyle\int_0^2\sqrt{x'(t)^2+y'(t)^2}\,\mathrm dt$
$\displaystyle=\int_0^2\sqrt{(e^t\sin10t+10e^t\cos10t)^2+(e^t\cos10t-10e^t\sin10t)^2}\,\mathrm dt$
$\displaystyle=\int_0^2e^t\sqrt{\sin^210t+20\sin10t\cos10t+100\cos^210t+\cos^210t-20\sin10t\cos10t+100\sin^210t}\,\mathrm dt$
$=\displaystyle\int_0^2e^t\sqrt{1+100}\,\mathrm dt$
$=\displaystyle\sqrt{101}(e^2-1)$

Which one is 2/3 real rational irrational integer whole natural

mixas84 [53]

$\frac{2}{3}$ is real and rational.

For it to be an integer, whole, or natural number, it would have to be a whole number. Since it can be written as a repeating decimal (.6666666...) it is not irrational either.

Please answer correctly

Answer:

Graph B

Step-by-step explanation:

the "x" and "y" represent $\frac{rise}{run}$

so therefore, it's $\frac{-2}{-2}$ , $\frac{-1}{-1}$ , $\frac{1}{1}$ , $\frac{2}{2}$

you would start at (0,0) or the origin

and count over one and up one, or however many units the fraction/chart tells you to count up
