In problem graph the curve whose parametric equations are given and show its orientation. Find the rectangular equation of each curve. Verify your graph using a graphing utility.
$x = \sqrt{t} + 4, y = \sqrt{t} - 4 t 鈮� 0$

Short Answer

Expert verified

The answer is $y = x - 8 .$

Step by step solution

Step. 1. Given information.

$x = \sqrt{t} + 4, y = \sqrt{t} - 4$ is given.

Step 2. Calculation.

Graph the curve defined by the parametric equations -

t	x	y	(x, y)
$0$	$4$	$- 4$	$(4, - 4)$
$1$	$5$	$- 3$	$(5, - 3)$
$2$	$\sqrt{2} + 4$	$\sqrt{2} - 4$	$(\sqrt{2} + 4, \sqrt{2} - 4)$
$3$	$\sqrt{3} + 4$	$\sqrt{3} - 4$	$(\sqrt{3} + 4, \sqrt{3} - 4)$

We find the rectangular equation by eliminating the parameter t from the parametric equations.

$x = \sqrt{t} + 4 x - 4 = \sqrt{t} {(x - 4)}^{2} = t t = {(x - 4)}^{2}$

Put the value of t-

$y = \sqrt{t} - 4 y = \sqrt{{(x - 4)}^{2}} - 4 y = x - 4 - 4 y = x - 8$

Thus, the equation is $y = x - 8$ .
