Answer 4

What is the context of this question? Seems its incomplete

Answer 5

wdym

Answer 6

If it is just what you attached, then the solution is:
v(t) = the sum of f(t) and g(t)

Answer 7

1 business day is 8 hours
t represents time in hours
f(t)=12(1.20)^t
g(t)=-4.5t

Answer 8

Add the two functions and call the resulting function v(t).

Answer 9

?

Answer 10

Yes

Answer 11

Can you add the two?

Answer 12

how

Answer 13

14.4^t + 4.5t

Answer 14

f(t)=12(1.20)^t
g(t)=-4.5t
v(t) = f(t) + g(t) = 12(1.20)^t + (-4.5t) = 12(1.20)^t - 4.5t

Answer 15

huh?

Answer 16

The first function is exponential and the second one is linear. If you are looking for simplification then there is no further simplification

Answer 17

so

Answer 18

im confused

Answer 19

There is no value at this stage, just an equation

Answer 20

so what is the answer

Answer 21

v(t) = 12(1.20)^t - 4.5t

Answer 22

so if i were to put this equation on a graph how would I

Answer 23

is the equation linear, quadratic, exponential, or logarithmic

Answer 24

You better use a graphing tool like desmos. It is a mixed function

Answer 25

they want us using this edmentum graphing tool

Answer 26

Can you copy the equation into this tool?

Answer 27

no

Answer 28

It would be a custom function

Answer 29

Does it allow manually adding/typing the function?

Answer 30

typing

Answer 31

But not copy-paste?

Answer 32

we can copy and paste

Answer 33

Ok, then you can copy here and paste into your tool

Answer 34

If i paste this v(t) = 12(1.20)^t - 4.5t it will say it cannot be plotted

Answer 35

Have you tried?

Answer 36

.. as custom

Answer 37

I am not familiar with this tool, sorry

Answer 38

i got this

Answer 39

This is the line and there is no variable in your equation. It is not what you need

Answer 40

Try x instead of t, see if it works

Answer 41

so

Answer 42

v(x) = 12(1.20)^x- 4.5x
or
12(1.20)^x- 4.5x

Answer 43

Either should do

Answer 44

?

Answer 45

Yes, good job

Answer 46

so do you know what the initial value of the graph is

Answer 47

It should be the value of v when t = 0
v(0) = 12(1.20)^0- 4.5(0) = 12*1 = 12

Answer 48

so do i solve this equation

Answer 49

It is solved for you:
v(0) = 12 is the initial value

Answer 50

oh thank you

Answer 51

do you know how to find the final value

Answer 52

Substitute t with 8 into equation and find the value of v(8). Remember it says 8 hours. The initial one was v(0) and the final should be v(8)

Answer 53

which equation

Answer 54

12(1.20)^x- 4.5x

Answer 55

12(1.20)^8-4.5(8)?

Answer 56

Yes

Answer 57

Let me know what you get

Answer 58

I got 15

Answer 59

It is close but not the exact answer

Answer 60

we dont need the exact answer we need to know a answer close to it

Answer 61

they asked "about" how much

Answer 62

15.6 is the rounded number

Answer 63

You may put 15 or 16. But you did it, congrats

Answer 64

its too late i already submitted it 0.0
