Question

Medal And Fan

Answer 1

Take the month you were born in. Multiply it by 4, add 13, multiply by 25, subtract 200, add the day you were born, multiply by 2, subtract 40, multiply by 50, add the last two digits of your birth year, subtract 10500…. viola! Your birth date! Impress your friends!

Now, use your birthday for some more math fun.

You can locate graph paper here.

Create a quadratic function, f(x), in vertex form. The a should be between 4 and –4, the h will be your birth month, and the k will be your birth day. Write your equation below.

Using complete sentences, explain how to convert your birthday function into standard form.

Graph your function. Include your graph below.

Using complete sentences, explain how to find the average rate of change for f(x) from x = 4 to x = 7.

Answer 10

:O didn't feel like psh

Answer 11

lol can u help?

Answer 12

i can try not really understanding what it's saying

Answer 13

read it and i think you use this formula

Answer 14

whats the question lol read 2 or 3

Answer 15

create a function, explain from function to standard, graph, and rate of change?

Answer 16

igtg soon can we speed this up and so f(x)=8x+12

Answer 17

they want you to know what
quadratic function, f(x), in vertex form.
means

it means the equation looks like this:
f(x)=a(x−h)2+k

they want you to replace the letters "a", "h", and "k" with numbers (based on your birthday)
except for "a".
The a should be between 4 and –4,

Answer 18

\[f(x)=a(x-h)^{2}+k\]

Answer 19

h is your birth month k is your birth day

Answer 20

aug 12 my birthday which was tuesday :DD

Answer 21

8/12

Answer 22

pick a number between 4 and -4

Answer 23

2 igtg in like 3mins can we speed this up

Answer 24

oh and happy bday btw

Answer 25

ty

Answer 26

this will take longer than 3 minutes to explain being theres multiple parts to the question

Answer 27

can u just give the answer i will figure it out later

Answer 28

\[f(x)=2(x-12^{2})+8\]

Answer 29

i dont know the answer myself i im reading while doing this and i dont even have all this information that will be your function tho

Answer 30

part 1 is done now we need to convert that to standard form which means expanding (x-12)^2

Answer 31

so whats the answer for part 1

Answer 32

(x-12)(x-12)
x^2-12x
-12x+144
so standard form is \[f(x)=2(x^2-24x+144)+8\]

Answer 33

part 1 is \[f(x)=2(x-12)^2+8\]

Answer 34

oh ok i understand

Answer 35

part 2 will be the next equation i gave you

Answer 36

yea i get that

Answer 37

now we need to graph this can you do that on your own?

Answer 38

not really

Answer 39

this is what i got on a quadratiic function calculator

Answer 40

now for part 4
\[f(x)=\frac{ 4-7 }{ 4 }×100\]

Answer 41

\[f(x)=\frac{ -3 }{ 4 }×1000\]

Answer 42

\[f(x)=-.75×100\]

Answer 43

\[f(x)=-75%\]

Answer 44

it told me to graph

Answer 45

i posted a screenshot of the graph i got

Answer 46

i cant send that let me give u a graph

Answer 47

Answer 54

dude just give me the points to plot and i will do it

Answer 55

@KlOwNlOvE

Answer 56

please help man i really gtg soon

Answer 57

.6x^2
.3x
.9Y

(-.3,.9)
(0,9)

Answer 58

what isnt it like 5 points to plot

Answer 59

ok skip that part lets do number 4

Answer 60

@KlOwNlOvE

Answer 61

#3 is confusing me very so
#4 rate of increase from 4-7
\[rateofincrease=\frac{ new number-old number }{old price }\]

Answer 62

\[\frac{ 7-4 }{ 4 }\]

Answer 63

\[\frac{ 3 }{ 4 }\]

Answer 64

divide numorator by denominator \[3\div4=.75\] to get the percent of increase we multiply by 100 \[.75*100=75\]
75%

Answer 65

thx
