The average rate of change for the height of the plant measured in centimeters per day between day 0 and day 20 is 1.32 cm per day.
<h3>What is average height?</h3>
The average height is the ratio of change in height of the plant and the time taken taken for that change.
Given is the height of a plant in centimeters is modeled as a function of time, in days.
For day 0, the height is 18cm and the height for day 20 is 42 cm, then the average height change is
height per day = 42 - 18/ 20 -0
height per day = 1.2 cm/day
Thus, the average height of plant is 1.2 cm/day.

Future value with annuity:
The future value formula, for an annuity, is:
An annuity means that a number of payments happen during the period(an year, for example.
P is the value of the deposit, r is the interest rate, as a decimal, and n is the number of deposits.
In this question:
1000 € each year, so 
Interest rate of 6%, so 
One application per year for 8 years, so 
Total amount:
There will be 9897.47€ in the account.
La cantidad será de 9897.47€.

Answer: 87 c
Step-by-step explanation:
To evaluate the cost per juice box, we must first factor out the bag of apples from the equation. So we will disregard the price of the apples from the total price and also disregard the existence of the apples altogether.
Our new subtotal is $15.66 for eighteen juiceboxes. To find the cost for one juicebox, we divide the price & the # of juiceboxes by 18.
15.66÷18=0.87, therefore each juicebox is 87 cents.
The total tickets sold at the fair = 50 tickets.
Kayla and Bianca each bought one ticket, it could be any numbered. We can start with anyone and find their probability.
If Kayla got ticket numbered #7, its probability would be 1 out of 50.
Then there would be 49 tickets remaining for Bianca at the fair.
If Bianca got ticket numbered #10, it probability would be 1 out of 49.
Total probability of (Kayla getting #7 AND Bianca getting #10) would be 1/(50x49) = 1/(2,450) = 0.0004081 = 0.0408%.
Hence, final answer is
