Answer:

Following are the solution to this question:

Step-by-step explanation:

Please find the complete question in the attached file.

In the given equation, when the point t=0

So,

\to r(0) = (3 \cos 0)i + (0^4 - 6 \sin 0)j + (2e^{3\times 0})k)

           = (3 \times 1)i + (0 - 0)j + (2e^{0})k)\\\\ = 3i +  0j + (2 \times 1)k)\\\\ = 3i +  0j + 2k \\

The value of the coordinates are 3, 0, 2 . so, the equation of the line is:

\to \frac{(x-3)}{3 \cos \ t} = \frac{(y-0)}{(t^{4}-6 \sin \ t)} = \frac{(z-2)}{2e^{3t}}=k

What occurs when thermal energy is moved from one place to another
sveta [45]
Heat can be moved from one place to another by 3 methods: cunduction, which happends in solids, convection, which happends in fluids, and radiation. Conduction occurs when two objects are touching each other. Heat moves from the hot object to the cold object until the two objects are the same temperature. Convection happends when hotter areas of a liquid or gas rise to the colder areas. Both conduction and convection require some form of matter but radiation does not. Radiation does not rely on things in contact with a heat source and what is being heated. For example, we feel the sun everyday and it feels hot but we never touch it.

Can you bisect an angle using only a compass and a straight edge​
ahrayia [7]

Answer:

yes

Step-by-step explanation:

bisect = dividing it into two equal parts

if you were to line the angle up with the north (or really any line of the compass), you could find the center (you could find where two lines [the same distance from north] are on equal sides of north, or you could just find the center of the angle from sight)

and with the straight edge, you could easily divide the angle into two equal halves

joey made a deposit into an account that earns 6% simple interest.After three years, joey had earned $400. How much was joey's i
Sergio [31]

Answer:

Step-by-step explanation:

To find the amount deposited, we will simply use the formula for calculating simple interest.

Simple Interest = pxrxt/100     (fraction)

Where p = principal

      R= Rate

           T= Time

Principal is the initial amount deposited which we are ask to find.

R is given to be 6%  and T is the time which is given in years

Simple interest is the interest earned over the year which is given to be $400

Lets substitute our variable into the equation

Simple Interest = pxrxt/100    (fraction)

$400  = P × 6 × 3   /     100

$400 = 18p/100    (fraction)

We will then cross multiply

$40 000  =   18 P

To get  the value of P, we divide both-side of the equation by 18

4000/18 = 18p/18     (fractions)

$2222.22 =  P

P = $2222.22
