I'll add a picture so it can make more sense to you. :)

We'll use the picture below as an example okay? :)
What you want to do is m<span>ultiply the numerator (top number) of the left-hand fraction by the denominator (bottom number) of the right-hand fraction. Then multiply the numerator (top number) of the right-hand fraction by the denominator (bottom number) of the left-hand fraction. Next step is to set the two products equal to each other. Then s<span>olve for the variable. If you look at the picture while reading the steps, then I think it'll make more sense.
I really hope this helps :)</span></span>

Directions-Write an exponential function to model each situation. Then find the value of the function after the given amount of
nignag [31]

Answer:

We can now write this is a function of time in years leading to

f

(

x

)

=

200

(

.94

)

x

f

(

5

)

≈

147

Explanation:

Firs you should consider that if its exponential then it has some form similar to

3

x

. Where we have some known part (3) and the unknown part (

x

) that we are trying to find out. Mathematically we can say it has the form

a

x

. In this case we know what the

a

is and that is the entire population that was given to us. We know over time it will change but why are we even using the exponential model.

Well it turns out that if you multiply some value over and over again it has this form. Example we multiply

2

⋅

2

⋅

2

⋅

2

=

2

4

. So if something doubled over time then this is what would happen.

Now the problem is that it will continue to decrease at the same rate leading to

a

⋅

(

.94

)

because only

94

%

of the population remains each year. After two years

a

.94

)

⋅

(

)

. We can now write this is a function of time in years leading to

f

x

)

=

A car rental company has two rental rates. rate 1 is $64 per day pluus $.16 per mile. rate 2 is $128 per day plus $.08 per mile.
kvv77 [185]
D is days
m is miles

0.16m + 64d (this is rate 1)
0.08m + 128d ( this is rate 2)

since you plan to rent for one day, input d as 1.

0.16m + 64(1)
0.08m + 128(1)

i hope i gave you enough hints

what is the multiplicative rate of change for the following coordinates (-1, .8) (0,2) (1,5) (2,12.5)
egoroff_w [7]
We can present these coordinates in tabulate form

    x         y
   -1       0.8
   0         2
    1         5
    2      12.5

We work the multiplicative rate of change by finding out the increase ratio

12.5 ÷ 5 = 2.5
5 ÷ 2 = 2.5
2 ÷ 0.8 = 2.5

The ratio results in the same ratio every time, which is 2.5

The multiplicative rate of change = 2.5
