Answer 2

Omg thanks for being here :D @misty1212

Answer 3

HI!!

Answer 4

what do you need help with? you are supposed to plug in a bunch of numbers
use a calculator

Answer 5

I did that that is in the document. Here is what I have- 4.

a.


x 100 + 23x 90(1.2x)

0 100 90

2 146 129.6
 
 
3 169 155.5
 
 
4 192 186.6
 
 
5 215 223.9
 

b.

Approximately between x=4 and x=5 so when x=4.5 both functions will have the same value. Because, m(x) goes from being smaller than s(x), to larger than s(x) between x=4 and x=5, so somewhere in that interval of numbers, both functions must intersect and have the same value.

c.






d. The x axis= the week #, week 0 (initial value through week 5
The y value represents the # of organisms present.
So each point on the graph (x,y)= (week #, population of organisms)

e.
To determine the solution from the graph, I have to estimate the intersection point (x,y).

f.
I need help on C and F

Answer 6

C

Answer 7

DO i choose the plot one and copy it or no ?

Answer 8

so there are two points where both lines intersect ????

Answer 9

I thought so but I'm still not 100% sure wait do I need to put this in desmos?

Answer 10

but what are the points? like I have to show them so in desmos how do i do this

is it right misty ???

Answer 12

i guess so, i used wolfram

Answer 13

looks like about \(4.43\)

Answer 14

wait so its right?

Answer 15

you don't want the negative answer, you want the positive one
take a look at the link i sent

Answer 16

ahhh so

Answer 17

that would be c right

Answer 18

ohh okay so i used desmos to graph this
that's why ....................
i had tooo zooooooooO.Oooooooooooooooooom out to see the other intersection points :'/

Answer 19

alright so to clarify XD That is the one i put for c right ? SO now we can do F lol ok @Nnesha

Answer 20

best of luck!! @Sparklestaraa if i work like this
like previous 2 hour i'll probably get medal in real life :D :PD
bye :P :D

Answer 21

XD haha true u would :P I would love to give u a million @Nnesha

Answer 22

nope i'm not saying for that medal
i mean we r almost on right tra k
like if i work hard in real life :P :Dlol

Answer 23

@misty1212 thanks for wolfram
but pretty complicated to use that

Answer 24

for part C u need both intersection point

Answer 25

Lol i know :P but i was giving u one anyway :P Yes u have to pay to almost use wolfram alpha. :D WAIT hold on xD Are there 2 points of intersection xD

Answer 26

IS this what i need to put for C?

Answer 27

nope both points where lines intersect

Answer 28

Answer 29

ahhh ok so can we go f @Nnesha

Answer 30

yes wo now we need positive order pair which is ( 4.43 , 201.960)

Answer 31

:) ok :)

Answer 32

so what do we need to do?

Answer 33

y represent number of organism

Answer 34

Well i think what is best is to take the points like what are the numbers for the points and then describe what they refer too. Because I still only understood the picture of C not what the actual points are

Answer 35

@Nnesha

Answer 36

for example like this
both order pair have x and y values

oaky so two times lines intersect
both have x and y values
