a) Differential equation (initial value problem) for the mass of the copper sulfate would be dm/dt = 0
b) m(t)=0
What is Differential equation?
A differential equation in mathematics is an equation that connects the derivatives of one or more unknown functions. Applications typically use functions to describe physical quantities, derivatives to indicate the rates at which those quantities change, and differential equations to create a relationship between the two.
a) Solution is flowing out of the tank. This can be expressed mathematically as:
dm/dt = (flow rate of solution into tank) - (flow rate of solution out of tank)
= (2 l/min) - (2 l/min)
= 0
Therefore, the differential equation for the mass of the copper sulfate in the tank is:
dm/dt = 0
This is a simple differential equation with a constant coefficient of 0, and it can be easily solved by integrating both sides of the equation with respect to time.
b. To solve the differential equation, we can write:
m(t) = integral(0, t, dm/dt)
= integral(0, t, 0)
= 0
Since the coefficient of the derivative is 0, the solution to the differential equation is a constant function with a value of 0. This means that the mass of the copper sulfate in the tank will remain constant over time, regardless of the flow rates of the solution into and out of the tank.

The equation of f(x) from the graph if, G(x) = x², is F(x) = 2x² + 3, so option A is correct.
What is a graph?A graph is a structure made up of a collection of things, where some object pairs are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.
Given:
G(x) = x²,
As you can see from the graph, the vertex of the parabola is (0, 3),
Write the equation of a parabola as shown below,
y = a(x - 0)² + 3
y = ax² + 3
Here a is the slope of the parabola,
slope = 4 / 2 (from the graph),

A cargo ship left port a and is headed across the ocean to shipping port b. After one month, the ship stopped at a refueling station along a path described by a vector with components leftanglebracket 14, 23 rightanglebracket. After another month, on the same path, the ship reached port b, twice the distance from port a as the fueling station. What are the characteristics of the vector representing the path of the ship?.
Answer:
Step-by-step explanation:
The vector representing the path of the ship from port A to the refueling station has components <14, 23>, and the vector representing the path from the refueling station to port B has twice the magnitude as the vector from port A to the refueling station.
To find the characteristics of the vector representing the path of the ship from port A to port B, we can add the two vectors together.
The sum of two vectors <a, b> and <c, d> is given by <a+c, b+d>. Therefore, the vector representing the path of the ship from port A to port B is given by:
<14, 23> + 2*<14, 23> = <14+214, 23+223> = <42, 69>
The vector representing the path of the ship from port A to port B is <42, 69>. This vector has a magnitude of √(42^2 + 69^2) = √(1764 + 4761) = √(6525) = 81 and a direction given by the angle theta, where tan(theta) = 69/42.

Kim purchased a new phone for $410, she put down $50 when she purchased it. If she pays a monthly bill of $35, which equation can used to determine how many months, m, it will take her to pay it off?
A 50m + 35 = 410
B 360 = 35 + m
C 35m + 50 = 419
D 50m - 35 = 410
Answer:
C
Step-by-step explanation:
I'm guessing you misspelled 410 as 419, but the equation is y=mx+b
Kim wants the money amount she puts in to pay off her $410 phone, or in other words, add up to $410.
The constant, or b, is 50. The m is 35, and the x is the months.
35m + 50 = 410
Answer: C. 35m + 50 = 410
Step-by-step explanation:
We know the cost is 410, so it will be = 410
We know that she pays 35 each month, which mean it is 35m
She put down 50 at the beginning, so it is + 50
So our equation is
35m + 50 = 410
How do you tell if the inverse of a function is a function?
The process by which we can tell that if the inverse of the function is also a function is the Horizontal Line Test .
The Inverse of the function is defined as a function, which can reverse into another function.
If the graph of the function does not pass the Horizontal Line Test, then the graphed function's inverse will not be a function; and
If all horizontal lines cross at most one spot on the original graph, then the inverse of the function will be a function.
Therefore , the horizontal line test is used to check whether the inverse is a function or not .

Answer:
Step-by-step explanation:
Lea wants to make two pillows for her new couch. She needs 314 square yards of fabric for the first pillow and 112 square yards of fabric for the second pillow. Lea wants to know how much fabric she will have to buy for both pillows. Which expression represents the total number of square yards of fabric she needs for both pillows?.
The equation for the total square yards of cloth she needs for both pillows is 314+112=426.
The total number of square yards of fabric Lea needs for both pillows is the sum of the fabric needed for the first pillow and the fabric needed for the second pillow. This can be represented by the expression:
314 square yards + 112 square yards = 426 square yards
Therefore, the expression that represents the total number of square yards of fabric Lea needs for both pillows is:
314 + 112 = 426
This expression would simplify to 426 square yards. This expression uses the addition operator (+) to add the two quantities of fabric that Lea needs for each pillow. The result is the total number of square yards of fabric that she needs for both pillows.

1. Reasoning What is the advantage of using coordinates O(0,0),
E(0, 2b), and F(2a, 0) rather than O(0, 0), E(0, b), and F(a, 0)?
Using coordinates O(0,0), E(0, 2b), and F(2a, 0) rather than O(0, 0), E(0, b), and F(a, 0) has the advantage of allowing the graph to be stretched or shrunk uniformly in both the x- and y-directions by a factor of 2. This can be useful if the scale of the graph needs to be adjusted, or if the graph needs to be compared to another graph with a different scale. It can also make the graph easier to read if the values of the variables being plotted are very large or very small.
By using coordinates that are multiples of the original coordinates, the shape of the graph is preserved, but the scale is changed. This can be useful if the purpose of the graph is to compare the relationships between different variables, rather than to provide an accurate representation of the actual values of the variables.
How do you describe a line on a graph?
A line on a graph is a series of points connected by a straight line. It is used to show continuous change or a relationship between two variables.
A line on a graph is a visual representation of a continuous change or a relationship between two variables. It is made up of a series of points connected by a straight line, making it easy to compare changes in data over a period of time. The points on the line represent the values for the two variables being graphed, with the horizontal axis (x-axis) representing one variable and the vertical axis (y-axis) representing the other. The points on the line can be joined with either a straight line or a curved line, depending on the type of data being graphed. For example, a straight line will be used to show a linear relationship between two variables, while a curved line might be used to show a non-linear relationship. By examining the line, it is possible to determine the rate of change or the correlation between the two variables being graphed.

Daniel has a yearly income of $41,300 and claims 4 exemptions. The amount allowed for each exemption is $900. His local tax is4 3/4%. How much local income tax should be withheld from his weekly earnings? (Round your answer to the nearest cent.)
Answer:
$34.37.
Step-by-step explanation:
To calculate Daniel's local income tax withholding, we first need to determine his taxable income. To do this, we subtract the value of his exemptions from his yearly income: $41,300 - (4 x $900) = $37,500.
Next, we need to convert the local tax rate of 4 3/4% to a decimal by dividing it by 100: 4 3/4% = 0.0475.
Finally, we can calculate Daniel's local income tax withholding by multiplying his taxable income by the local tax rate: $37,500 x 0.0475 = $1,793.75.
To find the amount of local income tax that should be withheld from Daniel's weekly earnings, we simply divide his total local income tax by the number of weeks in a year: $1,793.75 / 52 = $34.37. Therefore, Daniel's local income tax withholding from his weekly earnings should be $34.37.
