Answer:
Step-by-step explanation:
Given that a referral code is 2 letters (A-Z, no lowercases) followed by 4 digits (0-9), or it is 2 digits (0-9) followed by four letters (A-Z, no lowercases).
Digits are not allowed to repeat but letters can repeat.
Thus we find that 2 letters can be selected in
Since for numbers repitition is not allowed, 4 digits can be arranged in 9P4 ways
= 9*8*7*6
Total no of ways for I type=
For II type numbers are 2 and letters are 4.
So no of ways =
total referral codes possible =
Answer: $44,518
Step-by-step explanation:
Using the formula:
PV = P( )
PV = present value
P = Principal
r = rate
n = number of periods
From the question :
PV = ?
P = $10,000
r = 0.04
n = 5
Substituting into the formula , we have
PV = 10,000 ( )
PV = 10,000 ( )
PV = 10,000 (
PV = 10,000 ( 4.451822331 )
PV = 44518.22331
Therefore :
PV≈ $ 44,518
Answer:
X->-infinite, graph is positive +(infinite)
X-> + infinite, graph is negative (-infinite)
Step-by-step explanation:
When you study end behaviour of a polynomial, you verify it's highest exponent. If it is odd, like this exercise, it's Y values come from negative infinity to positive infinity. If the coefficient is negative, it is the opposite, it comes from positive infinite to negative infinite.
Answer:
Length: 12 meters
Step-by-step explanation:
Step 1:
Let us start with the formula of the perimeter of a rectangle, , where <em>l</em> represents the length of the rectangle, and <em>w</em> represents the width of the rectangle.
We can set width as variable <em>x</em>. We are also given that the length is three times the width, hence it can be represented as <em>3x</em>.
Step 2:
We can now write our equation and solve for <em>x</em> :
We set <em>x</em> as width, so the width is 4 meters. However, in this problem we are looking for the length. The length is three times the width, so it would be meters.
