The number of boxes in an airmail shipment is it continuous or discrete?

trasher [3.6K]

Answer:

The number of boxes in an airmail shipment is discrete.

<em>Here is the trick:</em> If you can count it with your fingers, it is discrete, otherwise it is continuous.

*Assume you have a lot of fingers sometimes.

An example of something discrete would be the number of people in a room, because you cannot ever have half a person it means you will always have a whole number and thus discrete.

Something continuous would be how tall you are. You may tell everyone that you are 5'8 but really you are probably 5 foot 8.10444124(some crazy long decimal) inches. Additionalyl people are constantly growing and shrinking at all times throughout their lives due to the gravity, bad posture and natural growth thus it is variable that is varying and continous.

Nicolet wants to buy a new state of the art computer for R35 000. She decides to save by depositing an amount of R500 once a mon

sineoko [7]

Answer:

54.72 months

Step-by-step explanation:

Given:

Future value = R35,000

Annuity = R500

Interest = 11.32% per year

Interest per month, r = $\frac{11.32}{12}$ = 0.943% = 0.00943

Let 'n' be the total time in months taken

Now,

Future value of annuity is calculated using the formula as:

$\textup{Future value}=\textup{Annuity}\times[\frac{(1+r)^n-1}{r}]$

on substituting the respective values, we get

$35000=500\times[\frac{(1+0.00943)^n-1}{0.00943}]$

or

$70=[\frac{(1.00943)^n-1}{0.00943}]$

or

1.6601 = 1.00943ⁿ

taking log both sides, we get

log(1.6601) = n × log(1.00943)

or

0.22= n × 0.00402

or

n = 54.72 months

Writing an equation of a probably given the vertex and focus

White raven [17]

The equation of the vertical parabola in vertex form is written as

$y=\frac{1}{4p}(x-h)^2+k$

Where (h, k) are the coordinates of the vertex and p is the focal distance.

The directrix of a parabola is a line which every point of the parabola is equally distant to this line and the focus of the parabola. The vertex is located between the focus and the directrix, therefore, the distance between the y-coordinate of the vertex and the directrix represents the focal distance.

$p=1-6=-5$

Using this value for p and (3, 1) as the vertex, we have our equation

$y=-\frac{1}{20}(x-3)^2+1$
