Consider the following. x = et − 5, y = e2t (a) Eliminate the parameter to find a Cartesian equation of the curve. (b) Sketch the curve and indicate with an arrow the direction in which the curve is traced as the parameter increases.

The Cartesian equation is

y = x² + 10x + 25

Step-by-step explanation:

Given the parametric equations:

x = e^t - 5

y = e^(2t)

We are required to obtain the Cartesian equation by eliminate the parameter 't'. To do this, let us rewrite the equation y = e^(2t) by taking square roots of both sides as

√y = e^t.

This can be easily subtracted from x = e^t - 5

Subtracting, we have

x - √y = e^t - 5 - e^t

x - √y = -5

√y = x + 5

Squaring both sides, we have

y = (x + 5)²

y = x² + 10x + 25.

And this is the Cartesian equation of the curve.

step-by-step explanation: liner would mean in a line and the only one that doesn't look like it's even thinking about forming a line would be the third one
