Consider the following vector function. R(t) = 9 2 t, e9t, e−9t (a) find the unit tangent and unit normal vectors t(t) and n(t)

garik1379 [7]

The unit tangent vector is T(u) and the unit normal vector is N(t) if the vector function. R(t) is equal to 9 2 t, e9t, e−9t.

<h3>What is vector?</h3>

It is defined as the quantity that has magnitude as well as direction also the vector always follows the sum triangle law.

We have vectored function:

$\rm R(t) = (9\sqrt{2t}, e^{9t}, e^{-9t})$

Find its derivative:

$\rm R'(t) = (9\sqrt{2}, 9e^{9t}, -9e^{-9t})$

Now its magnitude:

$\rm |R'(t) |= \sqrt{(9\sqrt{2})^2+ (9e^{9t})^2+ (-9e^{-9t})^2}$

After simplifying:

$\rm R'(t) = 9 \dfrac{e^{18t}+1}{e^{9t}}$

Now the unit tangent is:

$\rm T(u) = \dfrac{R'(t)}{|R'(t)|}$

After dividing and simplifying, we get:

$\rm T(u) = \dfrac{1}{e^{18t}+1} (\sqrt{2}e^{9t}, e^{18t}, -1)$

Now, finding the derivative of T(u), we get:

$\rm T'(u) = \dfrac{1}{(e^{18t}+1)^2} (9\sqrt{2}e^{9t}(1-e^{18t}), 18e^{18t}, 18e^{18t})$

Now finding its magnitude:

$\rm |T'(u) |= \dfrac{1}{(e^{18t}+1)^2} (9\sqrt{2}e^{9t}(1-e^{18t})^2+ (18e^{18t})^2+( 18e^{18t})^2)$

After simplifying, we get:

$\rm |T'(u)|= \dfrac{9\sqrt{2}e^{9t}}{e^{18t}+1}$

Now for the normal vector:

Divide T'(u) and |T'(u)|

We get:

$\rm N(t) = \dfrac{1}{e^{18t}+1} ( 1-e^{18t}, \sqrt{2}e^{9t}, \sqrt{2}e^{9t})$

Thus, the unit tangent vector is T(u) and the unit normal vector is N(t) if the vector function. R(t) is equal to 9 2 t, e9t, e−9t.

Pani-rosa [81]

Answer:

0.1513

Step-by-step explanation:

mean= 15.4

SD=4.5

P(20<X<28)

P((20-15.4)/4.5 < Z < (28-15.4)/4.5)

P(1.022 < Z< 2.8 )

From Z distribution table,

P(Z<2.8)= 0.99744

P(Z<1.022)= 0.84614

P(1.022 < Z< 2.8 )= P(Z<2.8)- P(Z<1.022)

= 0.99744-0.84614

= 0.1513

OLEGan [10]

The comparison of shoes placed on the floor by Helena next to each other change from reflection to translation.

<h3>What do you mean by reflection?</h3>

The reflection of a plane or shape is flipping the original figure with respect to a reference line.

The rule of reflection are given below,

Reflection about x-axis (x,y)-->(x,-y)
Reflection about y-axis (x,y)-->(-x,y)

Before training for the obstacle course, Helena bought a new pair of athletic shoes.

She placed the shoes on the floor next to each other and noticed that the right shoe looked just like a reflection of the left shoe.
This is because, the separating line works as the symmetry line between both the shoes.

Now she had accidentally purchased two left shoes. Now, if she puts a left shoe to another left shoe, then it looks like the translated image of the first shoe.

Hence, the comparison of shoes placed on the floor by Helena next to each other change from reflection to translation.
