Your parents have a credit card with a balance of $3,287.90 at an interest rate of 14.5% APR. They pay $1,200.00 each month on the due date until the card is paid off. How many months does it take to pay off the card, and what is the total amount paid including interest?
Each month, the interest for the current balance is calculated as:
$3,287.90 * 14.5% / 12 = $48.22
How Do Interest Rates Work?
The amount a lender charges a borrower is called an interest rate, and it is expressed as a percentage of the principal, or the loaned amount. Typically, a loan's interest rate is expressed as an annual percentage rate, or APR (APR).
The new balance after each payment is:
$3,287.90 + $48.22 - $1,200.00 = $2,147.12
Repeat the calculation until the balance is zero:
Month 1:
Balance: $3,287.90
Interest: $48.22
New Balance: $2,147.12
Month 2:
Balance: $2,147.12
Interest: $31.14
New Balance: $1,178.26
...
Month 26:
Balance: $0.00
So, it takes 26 months to pay off the credit card, and the total amount paid including interest is $31,622.68.

suppose a pipe containing water with 0.2 kg of sugar per liter runs into a tank filled with 400 liters of water currently containing 10 kg of sugar. the flow from the pipe enters the tank at 10 liters per minute. the solution is kept thoroughly mixed and drains from the tank at the same rate. setup and solve an initial value differential equation.
An initial value differential equation is S(t) = 10 * e^(-0.005t).
Sugar Amount Differential EquationThe initial value differential equation for the amount of sugar in the tank can be modeled as:
dS/dt = (0.2 kg/L) * 10 L/min - (S/400 L) * 10 L/min
where S is the amount of sugar in the tank in kg and t is the time in minutes.We can solve this equation using separation of variables:dS/S = -0.005 dt
Integrating both sides:ln(S) = -0.005t + C
Using the initial condition that S = 10 kg at t = 0:ln(10) = C
So the solution is:S(t) = 10 * e^(-0.005t)

Is it ever possible to have a graph of a function that is symmetric about the y-axis AND the origin? Explain your thinking. (say yes or no and explain in more detail)
Yes, it is possible to have a graph of a function that is symmetric about both the y-axis and the origin. This means that if (x, y) is a point on the graph, then (-x, y) and (x, -y) are also points on the graph.
In other words, the function has both reflectional symmetry about the y-axis and rotational symmetry about the origin. An example of such a function is y = x², which is a parabolic function that opens upwards and is symmetric about both the y-axis and the origin.
What is the function about?A graph is symmetric about the y-axis if the graph is unchanged when reflected over the y-axis. This means that for any point (x,y) on the graph, the corresponding point (-x,-y) will also be on the graph. A graph is symmetric about the origin if the graph is unchanged when reflected over the origin.
Therefore, This means that for any point (x,y) on the graph, the corresponding point (-x,y) will also be on the graph. When a graph is symmetric about both the y-axis and the origin, it means that the graph is unchanged when reflected over either the y-axis or the origin.

What is Pythagorean theorem?Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.
here, we have,
this is a Pythagorean theorem problem, and it involves right triangles.
If this is the case, then we can use the formula: a² + b² = c².
In this case, it gives us the values of a and b,
so we have 3² + 4² = c².
This is equal to 9 + 16 = c², and further simplified, 25 = c².
So we can then find the square root of 25,
written as √25, which would equal 5,

75° 30’ convert into radian
When 75°30' converted into radian it will be 1.309 radians.
What do you mean by radian?A radian is a unit of measurement for angles in mathematics. It is defined as the angle formed at the center of a circle by an arc that is equal in length to the radius of the circle. In other words, a radian is the angle that subtends an arc equal in length to the radius of the circle.
The radian is used as a unit of measurement because it provides a convenient and natural way to describe angles in terms of their relationship to circles. It allows for the calculation of angles in terms of lengths, making it easier to solve problems involving circular motion and trigonometry. The conversion between degrees and radians is given by the formula: 1 radian = 180/π degrees, where π is the mathematical constant pi.
To convert degrees to radians, use the formula: radians = (degrees × π) / 180.
For 75° 30', the conversion to radians is:
radians = (75° 30' * π) / 180 = (75 + 30/60) * π / 180 = 1.309 radians.

Hudson bought snacks for his team's practice. He bought a bag of apples for $1.59
and a 10-pack of juice bottles. The total cost before tax was $7-39.
Write and solve an
equation which can be used to determine r, how much each bottle of juice cost.
Answer:
Step-by-step explanation:
Let r be the cost of each juice bottle.
The total cost of the juice bottles is 10 * r = 10r.
The total cost of the apples and the juice is $1.59 + 10r = $7.39.
We can set up an equation using the above information:
$1.59 + 10r = $7.39
10r = $7.39 - $1.59 = $5.80
r = $5.80 / 10 = $0.58
Therefore, each juice bottle costs $0.58.

The city is building a rectangular parking lot. The city wants the width of the parking lot to be 8 yards. The area of the parking lot must be at most 80 square yards. (These are city regulations.) Write an Inequality that describes the possible lengths (in yards) of the parking lot.
Use l for the Length of the rectangular parking lot.
Answer:The area of the parking lot is length * width. If the width of the parking lot is 8 yards, the area of the parking lot can be represented by the inequality:
Area <= 80
length * 8 <= 80
To get the possible lengths of the parking lot we need to divide both sides by 8:
length <= 10
Therefore, the inequality that describes the possible lengths of the parking lot (in yards) is:
length <= 10 yards
The possible lengths of the parking lot is any value less than or equal to 10 yards.
