A <em>function </em>is a rule that assigns each vale of the independent variable to exactly one vale of the dependent variable.

The missing word is the function.

Point to remember:

The definition says that two values of x(independent variable ) may correspond to one value of y(dependent variable) but the vice versa is not true( means two values of y(dependent variable ) does not correspond to one value of x(independent variable) ). This explanation is very powerful tool to check that whether a relation is a function or not.

What is 328.618 round to the nearest hundredth<br><br>A. 300<br>B. 328.60<br>C. 330<br>D. 328.62

son4ous [18]

Answer:

D. 328.62

Step-by-step explanation:

328.618 round to the nearest hundredth

Rounding to the nearest hundredth means 2 numbers after the decimal point

Numbers that rounds to 1 are 5, 6, 7, 8, 9

Number that rounds to 0 are 0, 1, 2, 3, 4

When rounding up, to the nearest hundredth, you will consider the next number after the two figures after the decimal point

Here, the next number after the two figures after the decimal point is 8

8 is a number that rounds to 1

Therefore, add 1 to 1 to have

gtnhenbr [62]

Answer:

a) t = 4

b) v = pi j + 5 k

c) rt = 1i + (pi t) j + (20 +5t )k

Step-by-step explanation:

You have the following vector equation for the position of a particle:

$r(t)=cos(\pi t)\hat{i}+sin(\pi t)\hat{j}+5t\hat{k}$ (1)

(a) The height of the helix is given by the value of the third component of the position vector r, that is, the z-component.

For a height of 20 you have:

$5t=20\\\\t=\frac{20}{5}=4$

(b) The velocity of the particle is the derivative, in time, of the vector position:

$v(t)=\frac{dr(t)}{dt}=-\pi sin(\pi t)\hat{i}+\pi cos(\pi t)\hat{j}+5\hat{k}$ (2)

and for t=4 (height = 20):

$v(t=4)=-\pi sin(\pi (4))\hat{i}+\pi cos(\pi (4))\hat{j}+5\hat{k}\\\\v(t=4)=-0\hat{i}+\pi\hat{j}+5\hat{k}$

(c) The vector parametric equation of the tangent line is given by:

$r_t(t)=r_o+vt$ (3)

ro: position of the particle for t=4

$r_o=cos(\pi (4))\hat{i}+sin(\pi (4))\hat{j}+20\hat{k}\\\\r_o=\hat{i}+0\hat{j}+20\hat{k}$

Then you replace ro and v in the equation (3):

$r_t=(1\hat{i}+20\hat{k})+(\pi \hat{j}+5\hat{k})t\\\\r_t=1\hat{i}+\pi t \hat{j}+(20+5t)\hat{k}$
