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.

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.
Do rigid transformations result in congruent figures?
Numbers that undergo rigid transformations are congruent. Congruent can always require precise changes even if you could conceive of them as forms that "appear exactly the same."
What is congruence?
A "matching" figure is one that can be placed perfectly on another. The bread has the same size and form when it is stacked. Match refers to objects that are precisely the same size and form. If one of two geometric figures can be consistently overlaid on the other, they are said to be congruent or to be in a congruent relationship.

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.

What are SAS and RHS congruence criterions?
The SAS states that two triangles that have two pairs of corresponding congruent sides and a pair of corresponding included congruent angles are congruent.
The RHS congruence criterion states that two right triangles that have a congruent pair of hypotenuses and a congruent pair of corresponding sides are congruent.
What is the SAS Congruence Criterion?The SAS congruence criterion is a postulate that shows that if two triangles have two pairs of corresponding congruent sides and a pair of corresponding included congruent angles, then both triangles are equal or congruent to each other.
What is the RHS Congruence Criterion?
The RHS stands for "right angle-hypotenuse-side". This congruence criterion states if two right triangles have congruence hypotenuses and a pair of corresponding congruent sides, then the two right triangles congruent to each other.
In summary, SAS congruence criterion proves that two triangles with two pairs of corresponding congruent sides and a pair of corresponding included congruent angles are congruent, while the RHS congruence criterion proves that two right triangles are congruent if they have equal pair of hypotenuses and a congruent pair of corresponding sides.

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.

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.
