how many unique 3 digit codes can be created from the 5 digits {1, 2, 3, 4, 5} if repeats are possible?
Answer:
53
Step-by-step explanation:
5 choices × 5 choices × 5 choices = 53 possible 3 digit codes including repeats
[tex]\boldsymbol{125}[/tex] unique [tex]3[/tex] digit codes can be created from the [tex]5[/tex] digits.
Number of arrangementsGiven that digits are [tex]=\boldsymbol{\{1,2,3,4,5 \}}[/tex].
Number of digits [tex]=\boldsymbol{5}[/tex]
With repetition" means that repetition is allowed. Thus, in each of the three places, we have five choices.
Therefore,
Number of unique three digit codes can be created from the five digits [tex]=5\times 5\times 5[/tex]
[tex]=\boldsymbol{125}[/tex]
So, [tex]\boldsymbol{125}[/tex] unique [tex]3[/tex] digit codes can be created from the [tex]5[/tex] digits.

Hal owns a printing company. Last Christmas, he charged $8 for a set of 25 greeting cards and $14 for a set of 50. a. Find two ordered pairs that represent the situation. (8,25) (14,50)
Answer:
(8, 25) and (14, 50)
Step-by-step explanation:
Total cost of a set of cards = price per unit x number of cards
= p x n
Thus, the total cost of printing each set of cards depends on the price per unit and number of cards. So that it can be represented in ordered pair as: (p, n).
For the first set of greeting cards,
the cost of printing a card = $8.0
number of cards printed = 25
This can be represented in ordered pair as (8, 25)
For the second set of greeting cards,
the cost of printing a card = $14.0
number of cards printed = 50
This can be represented in ordered pair as (14, 50)
Thus, the two ordered pairs that can represent the situations are (8, 25) and (14, 50).

Answer:
B) 2x-y=5
Step-by-step explanation:
Info we have:
The x-intercept is 2.5
The slope is 2/1=2
Therefore, our equation so far is y=2x+b
We plug in our x-intercept in and make y=0 to get b:
0=2(2.5)+b
0=5+b
-5=b
Therefore, the equation of the line is y=2x-5
Given our found equation, we can see which option works.
A is wrong because 2x+y=-5 -> y=-5-2x -> y=-2x-5
B is right because 2x-y=5 -> -y=5-2x -> y=-5+2x -> y=2x-5
C is wrong because x+2y=-5 -> 2y=-5-x -> y=-2.5-1/2x -> y=-1/2x-2.5
D is wrong because 2y-x=10 -> 2y=10+x -> y=5+1/2x -> y=1/2x+5

Approximately how many more cups can Tony
place on the remainder of the shelf?

16
Answer:
C. 16
Step-by-step explanation:
If you have 44 in space and 2 cups already on there ( 4 in) you now only have, 36 in space left.
So, 16 multiplied by 2 1/4 or 2.25 in decimal is 44 in total.
Therefore you need approximately 16 more cups.

find 2 consecutive integers whose sum is -97
Answer:
The first integer is: -49
The second integer: -49+1 = -48
Solution Check:
-49+(-48) = -97
Step-by-step explanation:
Let the first integer: [tex]x[/tex]
As we are looking for a consecutive integer, so
The second integer would be: [tex]x+1[/tex]
We know the sum of these two integers is -97. Thus, we can write this equation and solve for 'x'.
[tex]x+\left(x+1\right)=-97[/tex]
[tex]x+x+1=-97[/tex]
[tex]2x+1=-97[/tex]
[tex]2x=-98[/tex]
Divide both sides by 2
[tex]\frac{2x}{2}=\frac{-98}{2}[/tex]
[tex]x=-49[/tex]
Therefore,
The first integer is: -49
The second integer: -49+1 = -48
Solution Check:
-49+(-48) = -97
The selling price of a car is $18,000. Each year, it loses 15% of its value. Find the exponential function that gives the value of the car t years after its purchase. Write your answer in the form f(t)=a(b)t.
Answer:
f(t)=18,000(0.85)^t
Step-by-step explanation:
18,000 is the a value, and since it is depreciating 15% becomes -.15
so we are going to set it up like f(t)=18,000(1-0.15)^t
Final answer is f(t)=18,000(0.85)^t
The exponential function that gives the value of the car t years after its purchase is f(t) = $18,000(0.85^t).
What is the exponential function that represents the value of the car?
The car would cost less with the passage of time. This is because it loses its value with the passage of time.
The formula that can be used to determine the value of the car is:
FV = P (1 - r)^n
FV = Future value P = Present value R =rate of decline in valueN = number of yearsf(t) = $18,000 x (1 - 0.15^t)
f(t) = $18,000(0.85^t)

What is the equation written in vertex form of a parabola with a vertex of (5, 7) that passes through (2, -2)?
Answer:
y = - (x - 5)² + 7Step-by-step explanation:
y = a(x - h)² + k - vertex form of the equation of the parabola with vertex (h, k)
So the equation of the parabola with vertex (5, 7):
y = a(x - 5)² + 7
The parabola passes through point (2, -2) so if x=2 then y=-2
- 2 = a(2 - 5)² + 7
- 2 -7 = a(-3)² + 7 -7
- 9 = 9a
a = - 1
So, the equation written in vertex form of a parabola with a vertex of (5, 7) that passes through (2, -2):
y = - 1(x - 5)² + 7

Giovanni justifies whether the expression -4x-8 is equivalent to -2(x+1)-2(x+3) by letting x=3 in both expressions. What is the value of each expression when x=3.
3 and -20
4 and 4
-20 and -20
3 and 4
Answer:
The value of each expression when x=3 will be -20 and -20.
Step-by-step explanation:
Given the expression
-4x-8
setting x=3
= -4(3)-8
=-12-8
=-20
Given the expression
-2(x+1)-2(x+3)
setting x=3
=-2(3+1)-2(3+3)
=-2(4)-2(6)
=-8-12
=-20
so we conclude that the value of both the expressions was -20 when we substituted the value x=3.
Therefore, the value of each expression when x=3 will be -20 and -20.
