There are an infinite number of them.

-- Think of any number.

-- Multiply  4  by your number.  Write it on top.

-- Multiply  5  by your number.  Write it on the bottom.

-- You have a new fraction that's equivalent to  4/5 .

How many different numbers can you think of ?
That's how many new fractions you can create
that are ALL equivalent to  4/5 .

What is the sum of the exterior angles of a convex polygon?
Volgvan

Answer:

A

Step-by-step explanation:

The sum of the exterior angles for each polygon is always 360°.

The sum of the interior angles for each polygon is always 180°(n-2).

If you have n-sided convex polygon, then

\left(\text{Sum of all interior angles}\right)+ \left(\text{ Sum of all exterior angles}\right)=180^{\circ}\cdot n

So,

\left(\text{Sum of all interior angles}\right)+ 180^{\circ}\cdot (n-2)=180^{\circ}\cdot n\\ \\\left(\text{Sum of all interior angles}\right)=180^{\circ}\cdot n-180^{\circ}\cdot (n-2)=180^{\circ}\cdot (n-n+2)=360^{\circ}

A new DVD is available for sale in a store one week after its release. The cumulative revenue, $R, from sales of the DVD in this
AnnyKZ [126]

Solution :

It is given that :

$f'(t) = (350 \ln   t)'$

       $=350(\ln t)'$

        $=\frac{350}{t}$

So, f(5)=350 \ln (5) \approx 563

     $f'(5) = \frac{350}{5}$

              =70

The relative change is then,

$\frac{f'(5)}{f(5)}=\frac{70}{350\ \ln(5)}$

         $=\frac{1}{5\ \ln(5)}$

         $\approx 0.12$

          =12\%

This means that after 5 weeks, the revenue from the DVD sales in $563 with a rate of change of $70 per week and the increasing at a continuous rate of 12% per week.
