Answer:

Sqrt of 160

Step-by-step explanation:

The distance, try to think it as a triangle, so you will find out that the distance equals the sqrt of(8-(-4))^2 + (9-5)^2, so it will be sqrt of(144+16) which is sqrt of 160, so the answer will be sqrt of 160

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

$x= s$

$y=1-4s$

$z=0$
