How do you find the length of the curve x=3t−t3x=3t-t^3, y=3t2y=3t^2, where 0≤t≤3√0<=t<=sqrt(3) ?

taurus [48]

It's simple, you just have to do this:

$L=\int\limits_{a}^{b}\sqrt{\left(\frac{dx}{dt}\right)^2+\left(\frac{dy}{dt}\right)^2}~dt$

$x=3t-t^3$

$\frac{dx}{dt}=3-3t^2$

$y=3t^2$

$\frac{dy}{dt}=6t$

replacing

$L=\int\limits_{0}^{\sqrt{3}}\sqrt{\left(3-3t^2\right)^2+\left(6t\right)^2}~dt$

$L=\int\limits_{0}^{\sqrt{3}}\sqrt{9-18t^2+9t^4+36t^2}~dt$

$L=\int\limits_{0}^{\sqrt{3}}\sqrt{9+9t^4+18t^2}~dt$

$L=\int\limits_{0}^{\sqrt{3}}\sqrt{(3t^2+3)^2}~dt$

$L=\int\limits_{0}^{\sqrt{3}}(3t^2+3)~dt$

$L=t^3+3t|_0^{\sqrt{3}}$

$\boxed{\boxed{L=3\sqrt{3}+3\sqrt{3}=6\sqrt{3}}}$

Orhan studied the relationship between temperature and sales of refreshments at the concession stands inside the football stadiu

Temka [501]

The equation for the linear function that relates temperature (x) and refreshment sales (y) from the considered option can be given by: Option C: y = 11x- 55

<h3>What is linear equation?</h3>

Linear equation is equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form y = mx + c

Linear equation with two variables, when graphed on cartesian plane with axes of those variables, give a straight line.

For this case, we see that the option C: y = 11x - 55 is such that each term is having at max one variable (therefore 1 degree) or no variable (therefore 0 degree).

Thus, option C represents a linear equation. Its graph is given below.

Option A has $x^2$ which is two degree, Option B has two degrees in y, and in Option D, there is x with three degrees.

Thus, the equation for the linear function that relates temperature (x) and refreshment sales (y) from the considered option can be given by: Option C: y = 11x- 55
