Question

A wrestling match has eliminations each round. The table below shows the number of wrestlers in each of the first 4 rounds of the tournament:


Round (x) 1 2 3 4
Wrestlers f(x) 64 32 18 9


Compute the average rate of change of f(x) from x = 1 to x = 4 and identify the meaning of that rate.
A)55; there were 55 fewer wrestlers between rounds 1 and 4
B)3; there were 3 rounds between rounds 1 and 4
C)negative fifty five over three; on average, there were 55 fewer players for every 3 rounds
D)negative three over fifty five; on average, there were 3 fewer players for every 55 rounds

Answer 1

@muscrat123 HEY CAN YOU HELP ME PLEASE

Answer 2

@campbell_st

Answer 3

WHY DO U KEEP TAGGING ME AFTER I SAY I DONT KNOW HOW TO ANSWER THE QUESTION????

Answer 4

i sorry i dont see you comment

Answer 5

if im not sure, I WILL NOT ANSWER. i dont want to give anybody an incorrect answer

Answer 6

i recommend @horsegirl27 @dan815 @jim_thompson5910 @misssunshinexxoxo @campbell_st and @nerlineg

Answer 7

average rate of change is the slope of the line

use the points (1, 64) and (4, 9)

Answer 8

yup campbell is right

Answer 9

yea so what i need to do next?

Answer 10

so what did you get as the slope...?

Answer 11

(1*64)(4*9)= 2304? is right?

Answer 12

i'm not good at math :(

Answer 13

slope = (change in y)/(change in x)

sometimes referred to as slope = rise/run

Answer 14

slope is x2-x1/ y2-y1

Answer 15

so the points need to match for x and y

slope = (64 - 9)/(1 - 4)

what do you get

Answer 16

-18.3

Answer 17

?

Answer 18

so for your question its

avg change = (change in wrestlers)/(change in rounds)

Answer 19

well why not leave it as a fraction.... seeing some of the answer choices are fractions

Answer 20

you have two points plug the x valule with the x vaule and y value with y

Answer 21

so as an improper fraction.. what do you thing the avg change of slope would be..?

Answer 22

i dont know :(

Answer 23

@campbell_st ???

Answer 24

are you there?

Answer 25

please i really need help on this

Answer 26

well you had a decimal value

avg change = (change in wrestlers)/(change in rounds)

= (64 - 9)/(1 - 4)

Answer 27

=-18.3?

Answer 28

can you give the answer as in improper fraction

Answer 29

how? i dont know how

Answer 30

what number is the change in wrestlers

what number is the change in rounds...?

Answer 31

Round (x) 1 2 3 4
Wrestlers f(x) 64 32 18 9

Answer 32

change in wrestlers 64 - 9 =
avg change = ------------------------------------ --------------
change in rounds 1- 4 =

what do you think the missing numbers in the fraction are..?

Answer 33

-55/ 3

Answer 34

wrestlers= 55
rounds= -3

Answer 35

great so you are looking at choices C or D

so read the choices and decide which should be your answer

Answer 36

-55/-3= 18.3

Answer 37

D?

Answer 38

but your answer choices don't contain a decimal... that's why I asked you to
write it as an improper fraction.

Answer 39

so you are saying the avg change is

\[avg ~change = \frac{-3}{55}\]

is that the same as you answer above

\[Avg~ change = \frac{-55}{3}\]

Answer 40

YES

Answer 41

well I Think you should choose C

the avg change = -55/3

Answer 42

Yea, thank you so much! can you help me with one more?

Answer 43

Which of the following options is an equivalent function to f(x) = 3(2)3x?

f(x) = 3(8)x
f(x) = 24x
f(x) = 27(8)x
f(x) = 3(8x)
