1. Rakesha claims that the equation f(n) 5 5n 2 7 is the function notation for the sequence that is
represented by the explicit formula an 5 22 1 5(n 2 1). James doesn’t understand how this can be
the case.
a. Help James by listing the steps to write the explicit formula of the given sequence in function
notation. Provide a rationale for each step.
b. Graph the function. Label the fi rst 5 values of the sequence on the graph.
2. Determine whether each table of values represents a linear function. For those that represent
linear functions, write the function. For those that do not, explain why not.

Select each correct answer.
Worker A earns less per hour than Worker B.
Worker B earns more after 10 hours than worker A.
Worker A earns $12.50 per hour.
After 20 hours of work, Worker A earns more than Worker B.
Answers
1st statement is correct
2nd statement is correct.
finding the average hours worker A does and then the average amount paid i got
average hrs = 22.6 hrs and average amount paid= $250
so comparing them to one hr i got the amount paid to worker A in one hr which is $1.11
so compare to worker B earnings and find the true statements

What is angle KNL
Enter your answer in the box
[]
Answers
Answer:
20
Step-by-step explanation:
So in case you did not know, MNJ and KNL have the same angle measure, so to find x you would just set each of the eqautions equal to each other. distribute the 3 to (x + 14) and get 5x+ 2 = 3x + 42. subtract 2 from one side and do the same on the other side. this would leave your eqaution looking like this: 5x-40= 3x, next subtract 5x from both sides and you will get -2x=-40, then vide by -2 and x will equal 20

You go to the store and notice the people standing in line. 7 adults and 4 children. If this ratio stays the same and there 55 people in the store. how many would be children?
Answers
Answer:
20
Step-by-step explanation:
7+4=11
11*5= 55
4*5=20 :)
The number of children and adults will be 35 and 20, respectively.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
You go into the store and observe the folks in queue. There are 7 adults and 4 children. If this ratio remains constant and there are 55 people in the store.
7x / 4x = constant
Then the equation is given below.
7x + 4x = 55
11x = 55
x = 11
Then the number of adults is given as,
7x = 7 (5) = 35
Then the number of children is given as,
4x = 4 (5) = 20
The number of children and adults will be 35 and 20, respectively.

feet, what is the width in simplest form?
Answers
Answer:
So, the length (L) = 7 3/4 ft = 31/4 (as an improper fraction)
the width (W) = (1/3)xL
So the width = 1/3 x (31/4) =

Environmentalists estimate an annual population decrease of giraffes in the wild of 3.5% due to development. This can be modeled by the function p(x) = 140,000(0.965)^x, where x is the number of years of tracking the populations. Conservationists have developed a sanctuary that has shown the ability to increase the population by 0.85% per year. The increase can be modeled by the function S(p) = p(1.0085)^x.
Which function represents S(p(x)), rounded to the nearest ten thousandth?
A. S(p(x)) = 135,100(0.9732)^x
B. S(p(x)) = 135,100(1.9735)^x
C. S(p(x)) = 140,000(0.9732)^x
D. S(p(x)) = 140,000(1.9735)^x
Answers
Answer:
S(p(x)) = 140,000(0.9732)^x
Step-by-step explanation:
Given the population functions:
ENVIRONMENTALIST: decline by 3.5% annually
p(x) = 140,000(0.965)^x
CONSERVATIONISTS: Increase by 0.85% annually ;
S(p) = p(1.0085)^x
Formulate S(p(x)) rounded to the nearest ten thousand
p(x) = 140,000(0.965)^x
S(p) = p(1.0085)^x
S(p(x)) = p(1.0085)^x
Where p(x) = 140,000(0.965)^x
S(p(x)) = 140,000(0.965)^x(1.0085)^x
S(p(x)) = 140,000(0.9732025)^x
S(p(x)) = 140,000(0.9732)^x

Anne owns a used car lot and in order to get cars to sell, she buys used cars at an
auction place. It costs $200 to attend the auction and she buys used cars at
$2,000 each. Last Tuesday, she purchased 10 cars. Which of the following
functions correctly represents this situation in function notation?
f(x) = 10x + 200
f(x) = 200x + 2,000
f(x) = 2,000x + 10
f(x) = 2,000x + 200
Answers
Answer:
It would be 2,000x+200
Step-by-step explanation:
okay it costs $200 to attend so that's a cost you are going to have to pay regardless. The $2,000 depends on how many cars you buy. So it would be 2,000 (times how ever many cars you buy) plus the $200.
