Carmen and Matt are conducting different chemistry experiments in school. In both experiments, each student starts with an initial amount of water in a flask. They combine two chemicals which react to produce more water. Carmen's experiment starts with 30 milliliters of water in a flask, and the water increases in volume by 8.5 milliliters per second. Matt's experiment starts with 10 milliliters of water and increases in volume by 28% each second.
Which two conclusions can be made if f represents the volume of water in Carmen's flask and g represents the volume of water in Matt's flask?
The volume of water in Carmen's flask is increasing at a faster rate than the volume of water in Matt's flask over the interval [6, 8].
The volume of water in Carmen's flask is increasing at a slower rate than the volume of water in Matt's flask over the interval [4, 6].
The volume of water in Carmen's flask will always be greater than the volume of water in Matt's flask.
The volume of water in Matt's flask will eventually be greater than the volume of water in Carmen's flask.
The volume of water in Carmen's flask is increasing at a slower rate than the volume of water in Matt's flask over the interval [0, 2].

Real life applications of chain rule
Answer:
The Chain Rule can also help us deduce rates of change in the real world. From the Chain Rule, we can see how variables like time, speed, distance, volume, and weight are interrelated. A horse is carrying a carriage on a dirt path.
One real-life application of the chain rule is the study of motion in a car that is traveling along a curved path.
What is the chain rule?The chain rule is a fundamental concept in calculus that enables us to calculate the derivative of composite functions.
Composite functions are functions that are constructed by combining two or more functions. The chain rule tells us how to calculate the derivative of a composite function by breaking it down into simpler parts.
One real-life application of the chain rule is in physics, specifically in the study of motion.
For example, suppose we have a car that is traveling along a curved path. We want to know the rate at which the car is changing its speed at a particular point on the path. To do this, we need to find the derivative of the car's speed with respect to time.

Marcy needs 150 feet of fabric for her project. She uses 20% of it. How many feet of fabric did she use for her project so far? You may use a bar model or double number line.
Answer:
The answer is 120 feet of fabric
Answer:
30 feet.
Step-by-step explanation:
Steps
First, convert the percentage discount to a decimal. 20 percent of 150 is 0.20 in decimal format.
Secondly, multiply the decimal discount by the price of the item to determine the savings in dollars.
In this case, the original fabric needed equals 150 feet, you would multiply 0.2 by 150 to get the answer.
Solution
20 percent *150 =
(20:100)*150 =
(20*150):100 =
3000:100 = 30
Therefore, she used 30 feet for her project so far.
All edge are 8 cm in length. What’s the surface area?
Answer:
192
Step-by-step explanation:
This is because its a square and all the sides on a square are equal so it would be:
top/bottom= 8*8
left/ right= 8*8
front/ back= 8*8
all equal 64 then you do 64*64*64 to get 192!
Hope this helped!

On her 21st birthday, Sydney deposited $400 in a new bank account that earns 3.7% interest compounded continuously. If there are no other deposits or withdrawals, how much interest will she have earned by her 60th birthday
Answer:
$1,649.80
Step-by-step explanation:
Sydney will have earned $1293.35 in interest by her 60th birthday.
How to find interest?To solve this problem, we need to use the formula for continuously compounded interest:
A = P [tex]e^{rt}[/tex]
Where:
A is the final amount of money in the account (including principal and interest)
P is the initial principal (in this case, $400)
r is the interest rate (in this case, 3.7% per year)
t is the number of years the money is invested (in this case, 39 years)
e is the mathematical constant approximately equal to 2.718
Plugging in the values from the problem, we get:
A = $400[tex]e^{0.037 \times 39}[/tex]
Calculating this, we find that A = $400[tex]e^{1.443}[/tex] = $1693.35
Therefore, he will have earned $1693.35 - $400 = $1293.35 in interest by her 60th birthday.
