Answer:

As the wheel makes this 270 degree counterclockwise rotation about the origin, the y-coordinate of the first car decreases from 80 to 0 and then further from 0 to -80, and finally increases to 0.

The x-coordinate decreases from 0 to -80 and then increases to 0; from there it increases further to 80.

Thus, the coordinates of the first car, after this 270-degree rotation, are (80, 0).

Find an equation of the tangent to the curve at the given point by both eliminating the parameter and without eliminating the pa
konstantin123 [22]

Answer:

y=2x-8

Step-by-step explanation:

The given parametric equation is;

x=6+ln(t),y=t^2+3

<h3><u>BY ELIMINATING THE PARAMETER</u></h3>

To eliminate the parameter we make t the subject in one equation and put it inside the other.

We make t the subject in x=6+ln(t) because it is easier.

\Rightarrow x-6=ln(t)

\Rightarrow {e}^{x-6}=e^{ln(t)}

\Rightarrow {e}^{x-6}=t

Or

t={e}^{x-6}

We now substitute this into y=t^2+3.

This gives us;

y=(e^{x-6})^2+3.

\Rightarrow y=e^{2(x-6)}+3.

We have now eliminated the parameter.

The equation of the tangent at (6,4) is given by;

y-y_1=m(x-x_1)

where the gradient function is given by;

\frac{dy}{dx}=2e^{2(x-6)}

We substitute x=6 into the gradient function to obtain the gradient.

\Rightarrow m=2e^{2(6-6)}

\Rightarrow m=2e^0

\Rightarrow m=2

The equation of the tangent becomes

y-4=2(x-6)

We simplify to obtain

y=2x-12+4

y=2x-8

<h3><u>WITHOUT ELIMINATING THE PARAMETER</u></h3>

The given parametric equation is;

x=6+ln(t),y=t^2+3

For x=6+ln(t)

\frac{dx}{dt}=\frac{1}{t}

For y=t^2+3

\frac{dy}{dt}=2t

The slope is given by;

\frac{dy}{dx}=\frac{\frac{dy}{dt} }{\frac{dx}{dt} }

\frac{dy}{dx}=\frac{2t }{\frac{1}{t} }

\frac{dy}{dx}=2t^2

At the point, (6,4), we plug in any of the values into the parametric equation and find the corresponding value for t.

Notice that

When x=6, 6=6+\ln(t)

6-6=\ln(t)

0=\ln(t)

e^0=e^\ln(t)

1=t

when y=4, 4=t^2+3

4-3=t^2

1=t^2

t=\pm1

But the slope is the same when we plug in any of these values for t.

\frac{dy}{dx}=2(\pm1)^2=2

The equation of the tangent becomes

y-4=2(x-6)

We simplify to obtain

y=2x-12+4

y=2x-8

ololo11 [35]
The rectangular part is 30 cm^2 and the triangular part is 10 because the base is the top of the trapezium subtracted from the base of 10.

So the overall area is 30 cm^2
