which question are you stuck on?

hushed token Jun 28, 2023, 5:21 AM

#

all of them

fervent walrus Jun 28, 2023, 5:23 AM

#

start by finding lengths you don't know

#

other than that, this is just rectangles and trapezoids
which you can get the area of with formulas

#

for the carpet one and the tile one, multiply the area by the price per area to get the price

hushed token Jun 28, 2023, 5:28 AM

#

how do i solve number 1

#

and 2

#

what r the equations for 3 and 4

fervent walrus Jun 28, 2023, 5:30 AM

#

hushed token how do i solve number 1

the den is a trapezoid + a rectangle

#

find area of each and add

fervent walrus Jun 28, 2023, 5:31 AM

#

fervent walrus for the carpet one and the tile one, multiply the area by the price per area to ...

this is for 3 and 4

okay thank you

#

can you please help me with this too

fervent walrus Jun 28, 2023, 5:35 AM

fervent walrus Jun 28, 2023, 5:36 AM

#

ah

hushed token Jun 28, 2023, 5:36 AM

#

and for part 2 i need help w 2

fervent walrus Jun 28, 2023, 5:37 AM

hushed token

you already have this one right

#

the pizza one

hushed token Jun 28, 2023, 5:38 AM

#

yeah i have the graph

#

i need help w questions 2 and 3

#

#

this is the graph for the pizza one

fervent walrus Jun 28, 2023, 5:39 AM

#

ok

#

that's right

hushed token Jun 28, 2023, 5:39 AM

#

this is the graph for the candle one

hushed token Jun 28, 2023, 5:40 AM

#

hushed token

these r the questions i need help w

hushed token Jun 28, 2023, 5:40 AM

#

hushed token

as well as this

fervent walrus Jun 28, 2023, 5:40 AM

#

you have the scatterplot, you have the equation and graph already, just put m(9) + b to get the expected cost for 9 toppings

#

for the candle one, "burning out" means its height is 0

#

find the x value where the y value of the line is 0

hushed token Jun 28, 2023, 5:42 AM

#

i scrolled through the graph snd it didnt show me

#

for the candle one

#

wait how do i do that

fervent walrus Jun 28, 2023, 5:43 AM

#

what

hushed token Jun 28, 2023, 5:43 AM

#

mbmb i didnt understand

hushed token Jun 28, 2023, 5:43 AM

#

fervent walrus find the x value where the y value of the line is 0

how do u do that

fervent walrus Jun 28, 2023, 5:43 AM

#

by...
-dragging right until you find the x intercept
-solving 0 = mx + b

hushed token Jun 28, 2023, 5:44 AM

#

is it ok if i can send u the link bc when i tried doing it it didnt work

fervent walrus Jun 28, 2023, 5:45 AM

#

#

one sec

#

oh ok i got it

#

how would i write the best-fit equation

fervent walrus Jun 28, 2023, 5:50 AM

#

desmos should put below the y1 ~ mx1 + b its values of m and b

#

write y = [insert value of m]x + [insert value of b]

hushed token Jun 28, 2023, 5:50 AM

#

oh ok

#

can u help me w this too

#

@fervent walrus

hushed token can u help me w this too

ok what are the rates you got

hushed token Jun 28, 2023, 5:58 AM

#

idk

#

how do i find the rates @fervent walrus

fervent walrus Jun 28, 2023, 6:07 AM

#

you just literally go to their website and find the highest 2 rates

#

bankrate.com/banking/cds/cd-rates

hushed token Jun 28, 2023, 6:08 AM

#

ok what do i do after that

#

@fervent walrus

fervent walrus Jun 28, 2023, 6:10 AM

#

you start with $1000

#

if you see the apy, to calculate the value after 5 years, what would you do? well, apy is annual compounding interest

#

so you multiply your starting amount by (1 + r) 5 times

#

or in other words, 1000(1 + r)^5

hushed token Jun 28, 2023, 6:11 AM

#

oh okok thank you

#

how do i do part 2

fervent walrus Jun 28, 2023, 6:12 AM

#

fervent walrus or in other words, 1000(1 + r)^5

*if it says term = 1 year

hushed token Jun 28, 2023, 6:12 AM

what

fervent walrus Jun 28, 2023, 6:12 AM

#

hushed token how do i do part 2

do you have the 2022 price and 2021 price

hushed token Jun 28, 2023, 6:12 AM

#

no i dont

fervent walrus Jun 28, 2023, 6:13 AM

#

follow the instructions they give you, then??

hushed token Jun 28, 2023, 6:14 AM

#

sry im not doing it rn i want to first understand the steps

fervent walrus Jun 28, 2023, 6:14 AM

#

let's say the 2022 price is 5 million dollars

#

and the 2021 price was 6 million dollars

#

use the formula they give in the image

#

to find the percentage decrease

#

(6 million - 5 million)/6 million * 100

#

= 17%

hushed token Jun 28, 2023, 6:17 AM

#

oh ok

#

how do i do number 3 and 4

fervent walrus Jun 28, 2023, 6:23 AM

#

use originalprice(1 - decayrate)^t/years

#

the reason this works is if t = 0 then you get the value is originalprice

#

and if t = 1 year then the value is (1-decayrate)originalprice

#

which is also correct

hushed token Jun 28, 2023, 6:27 AM

#

whats t

fervent walrus Jun 28, 2023, 6:29 AM

#

time

hushed token Jun 28, 2023, 6:30 AM

#

oh ok thank you

#

can you help me w this one

fervent walrus Jun 28, 2023, 6:36 AM

#

google the distance formula

hushed token Jun 28, 2023, 6:38 AM

#

ik the distance formula

#

what do i do after

#

@fervent walrus

fervent walrus Jun 28, 2023, 6:42 AM

#

plug in the points

hushed token Jun 28, 2023, 6:43 AM

#

ok how do i do number 2

fervent walrus Jun 28, 2023, 6:44 AM

#

midpoint is found by averaging the x coordinates and averaging the y coordinates

#

for example, (0,4) and (2,2) have a midpoint of (1,3)

hushed token Jun 28, 2023, 6:45 AM

#

oh ok

#

can you help me with these

#

@fervent walrus

fervent walrus Jun 28, 2023, 6:50 AM

#

i can't help you with every problem

#

spend some time trying to figure it out

hushed token Jun 28, 2023, 6:54 AM

#

okok this is the last one can u explain this one to me

#

@fervent walrus

fervent walrus Jun 28, 2023, 6:55 AM

#

they have not given you enough information but what you can do is say "these 2 things are the same" to make the SSS, SAS, and ASA work

hushed token Jun 28, 2023, 6:59 AM

#

ok ty how do i do part 2

#

@fervent walrus

fervent walrus Jun 28, 2023, 7:01 AM

#

what's wrong with concluding they're the same by AAA

#

it's that AAA is not a congruence rule
