Arc Length Formula [Parametric]: $\displaystyle AL = \int\limits^b_a {\sqrt{[x'(t)]^2 + [y(t)]^2}} \, dx$

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

$\displaystyle \left \{ {{x = t - cos(t)} \atop {y = 1 - sin(t)}} \right.$

Interval [0, π]

<u>Step 2: Find Arc Length</u>

[Parametrics] Differentiate [Basic Power Rule, Trig Differentiation]: $\displaystyle \left \{ {{x' = 1 + sin(t)} \atop {y' = -cos(t)}} \right.$
Substitute in variables [Arc Length Formula - Parametric]: $\displaystyle AL = \int\limits^{\pi}_0 {\sqrt{[1 + sin(t)]^2 + [-cos(t)]^2}} \, dx$
[Integrand] Simplify: $\displaystyle AL = \int\limits^{\pi}_0 {\sqrt{2[sin(x) + 1]} \, dx$
[Integral] Evaluate: $\displaystyle AL = \int\limits^{\pi}_0 {\sqrt{2[sin(x) + 1]} \, dx = 4\sqrt{2}$

PLEASE HELP THIS IS DUE IN AN HOUR!!!

Naily [24]

Answer:

<h2>The x-coordinate after the rotation is -10.</h2>

Step-by-step explanation:

A 810° rotation is equal to a 90° rotation. So, the transformation described gives the same result than rotating 90° only.

A 90° counterclockwise rotation is defined by the rule

$(x,y) \implies (-y,x)$

The given coordinate is $(8,10)$ . Using the rule, we have

$(8,10) \implies (-10,8)$

Therefore, the x-coordinate after the rotation is -10.

Feliz [49]

The answer is: 15 .
__________________________ _____
{Note: If this is a physics problem ; and the formula: "F = m*a" is for:
"Force = mass * acceleration" ; be sure that the correct units are used!}.
_______________________________________________________
Explanation:
_______________________________
F = m * a ;

Given m = 5 ;

a = 3 ;
___________________
F = 5 * 3 = 15 .
