Find the arc length of the partial circle..

Gala2k [10]

Answer:

The arc length of the partial circle is $6\pi\ units$

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

In this problem we have a 3/4 of a circle

the circumference is equal to

$C=(\frac{3}{4})2\pi r$

$C=\frac{3}{2}\pi r$

we have

$r=4\ units$

substitute

$C=\frac{3}{2}\pi (4)$

$C=6\pi\ units$

Consider the tables created using an initial investment of $1,000 and quarterly compounding of interest.

Andru [333]

Answer:

(d) The functions are not inverses because for each ordered pair (x, y) for one function, there is no corresponding ordered pair (y, x) for the other function.

Step-by-step explanation:

If functions are represented by a table of ordered pairs, their inverse function is the set of ordered pairs with the x- and y-values swapped.

Here, for (x, y) = (0.75, 1038.18), the pair from the other table that begins to correspond is (y, x) = (0.75, 1057.81). These reversed pairs are not the same, so the functions are not inverses of each other.

_____

<em>Comment on the tables</em>

Table A is for a 5-year investment; table B is for a 7.5 year investment. They cannot be inverses of each other.
