Find parametric equations for the tangent line to the curve with the given parametric equations at the specified point. x = t, y

DochEvi [55]

Answer:

Step-by-step explanation:

At the point (0, 1,0) t = 0

Find the tangent vector:

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

$\frac{dy}{dt}= -4e^{-4t}$

$\frac{dz}{dt}=5-5t^4$

The tangent vector for all points $\vec v(t)$ is

$\vec v(t) = \hat {i}-4e^{-4t}\hat{j}+(5-5t^4)\hat{k}$

$\rightarrow \vec v (0)= \hat{i}-4\hat{j}$

The vector equation of the tangent line is

$(x,y,z) = (0,1,0)+s(\hat{i}-4\hat{j})$

The parametric equation for this line are

$x= s$

$y=1-4s$

$z=0$

4. ABCD below is a rectangle. BE=6x+2 and ED=4x+6. Find the length of AC.

Nikolay [14]

Answer:

28 units

Step-by-step explanation:

ABCD is a rectangle. AC and BD are diagonals intersecting at point E.

Diagonals of a rectangle bisect each other.

$\therefore BE = ED$

$\therefore 6x + 2 = 4x + 6$

$\therefore 6x - 4x= 6-2$

$\therefore 2x= 4$

$\therefore x= \frac{4}{2}$

$\therefore x= 2$

$\therefore 6x + 2= 6*2+2= 12+2= 14$

$\therefore BE= 14\: units$

$\because BD = 2BE$

$\therefore BD = 2(14)= 28\: units$

$\because AC = BD$ (diagonals of a are equal in measure)

$\therefore AC = 28\: units$
