Anna purchased a new car for $25,000. The car will decrease in value 15% each year.
The value of Anna's car is modeled on the graph by function f where x is the time in years after Anna purchases her car.
Answers
I will assume that we want to find the function that predicts the value of the car after x years, which likely is an exponential decay.
The function is: f(x) = $25,000*(0.85)^x
And the graph can be seen at the end of the answer.
We know that the value of the car decreases by 15% each year, then we can model this with an exponential decay.
The general exponential decay is given by:
f(x) = A*(1 - r)^x
Where:
A is the initial value, then we have A = $25,000
x is the variable, in this case, would represent time in years.
r is the rate of decay, in this case, is the quotient between the percentage that decreases and 100%, so we will get: r = 15%/100% = 0.15
Then the exponential equation is:
f(x) = $25,000*(1 - 0.15)^x
= $25,000*(0.85)^x
This is the function that models the value of the car after x years, the graph can be seen below.

Answer:
Grape juice has 180 containers.
Step-by-step explanation:
Given that the ratio of containers of orange juice to containers of grape juice in a store is 5 orange juices to 4 grape juices.
i.e.
Orange Juice containers : Grape Juice containers = 5 : 4
Total containers = 405
It means if we divide 405 by 9, we get the 9 equal parts of 45.
i.e. 405 / 9 = 45
as
Orange Juice containers : Grape Juice containers = 5 : 4
It means the share of Grape Juice containers is 4 parts out of 9 parts.
Thus, multiply 45 by 4 to determine the number of containers grape juice have:
45 × 4 = 180 containers
Therefore, grape juice has 180 containers.

By calculating on the basis of compound interest, after 12 years Logan will have $242.9 in his account.
What is a compound interest?Compound interest is a type of interest that is compounded after time period it is said to be compounded. After that particular period, the interest is calculated and then added with the principle. For the next duration, the interest is calculated on the sum.
Here, the amount of money after n years as per compound interest,
S = P(1 + r)ⁿ.
Where, P = Principle = $180, r = rate of interest = 2.6%, n = time period = 12 years
Now, S = $180(1 + 2.6/100)¹² = $180(1 + 0.026)¹² = $180(1.026)¹² = $242.9
Hence, after 12 years, Logan will have $242.9 in his bank account.

There are 425 vegetables at a farmers market stand. Of the vegetables, 125 of them are carrots. What is the ratio of the number of carrots to the number of other vegetables at the stand?
Answers
Answer:
the ratio of the number of carrots to the number of other vegetables is 25 : 12
Step-by-step explanation:
The computation is shown below:
Given that
Total vegetables = 425
Out of which 125 vegetables represent carrot
the other vegatables should be
= 425 - 125
= 300
Now the ratio of the number of carrots to the number of other vegetables is
= 125 : 300
= 25 : 12
Hence, the ratio of the number of carrots to the number of other vegetables is 25 : 12

Five out of eight birds that visited the feeder ate the birdseed. If 60 birds ate the birdseed today, how many birds visited the feeder?
Answers
Answer:
Therefore, the birds visited the feeder = 96
Step-by-step explanation:
Five out of eight birds that visited the feeder ate the birdseed.
i.e. the ration is: 5/8
Given that 60 birds ate the birdseed today.
Note that if we multiply '5' by '12', we get the number 60.
Now, all we need to is to also multiply '8' by '12' to maintain the initial ratio which is 5/8.
i.e. (5×12) / (8×12) = 60/96
Therefore, the birds visited the feeder = 96
