Step-by-step explanation:
Permutation
:The number of ways to choose a sample of r elements from a set of n distinct objects where order does matter and replacements are not allowed.
Factorial
: There are n! ways of arranging n distinct objects into an ordered sequence.
Considering a situation when n = r in a permutation, nPr reduces to n!, a simple factorial of n.
Proof: 3P3 = 3!
n = 3 and r = 3
But 0! = 1
3P3 = 3!
You'd have to draw a table of x and y values first to be able to graph.
Step 1: Pick any number for x. Let's pick 2.
Step 2: Plug in 2 into the equation: y = 2^2 + 2(2) - 3
Step 3: Solve for y: 4 + 4 - 3 = 5
Step 4: So the point (ordered pair) would be (x, y) ⇒ (2, 5). You can plot that on the graph.
Follow these steps 2 more times to get at least three ordered pairs.
Make sure you have enough points to know where the graph curves, then you can connect the dots and now there you have a graph and chart :)
In this question, we're calculating how much you're going to need to pay in parking.
We know that it costs 50¢ per hour
We also know that you park for 7 hours.
Note: They're trying to trick you here with the $4 per day, you wouldn't use this information because you're not parking for the whole day.
Calculate how much you're paying per day by multiplying 7 by 0.50
7 × 0.50 = 3.5
Now, multiply how much you pay everyday (3.5) by the amount of days your'e working (5)
3.5 × 5 = 17.50
This means that you will be paying $17.50 for 5 days of parking
Answer:
$17.50
Answer:
53/243
Step-by-step explanation:
there you go!
