What is compound interest?
When you earn interest on your interest earnings as well as the money you have saved, this is known as compound interest. The interest you get is referred to as compound interest. Using simple math, you can see how this works: if you have $100 and it generates 5% interest annually, you will have $105 at the end of the first year. You'll have $110.25 at the conclusion of the second year.

What is a multiplicity example?
A multiplicity example in mathematics is when a function has multiple solutions to a given equation.
For example, when solving the equation x2 + 4x + 3 = 0, there are two solutions, x = -3 and x = -1. This means that the equation has a multiplicity of two. This can be seen in the graph of the equation, which has two points of intersection on the x-axis.
The multiplicity is a measure of how many solutions a given equation has. It can be determined by using the discriminant, which is the difference between the square of the coefficient of the highest degree term, and four times the product of the coefficients of the lower degree terms, and the constant. In the example above, the discriminant is 16 - 12, which is 4. The multiplicity of the equation is determined by the sign of the discriminant: if it is positive, the equation has two solutions; if it is zero, the equation has one solution; and if it is negative, the equation has no solutions.
The multiplicity of an equation can also be used to determine the nature of the graph of the equation. If the equation has a multiplicity of two, the graph is a parabola, which is a curved line that has two points of intersection on the x-axis. If the equation has a multiplicity of one, the graph is a line, which has only one point of intersection on the x-axis. If the equation has a multiplicity of zero, the graph is a circle, which has no points of intersection on the x-axis.
The concept of multiplicity is important in mathematics, as it can be used to determine the number of solutions an equation may have, as well as the nature of the graph of the equation. Knowing the multiplicity of an equation can help to simplify the process of solving the equation.

SSS:side,side,sideSAS:side,angle,sideAAS: angle, angle,sideASA: angle,side, angleSort the following steps into ones that are required, and ones that are not required, to show that △abc ≅ △dbc.
Each corresponding side of the two triangles is equal, we can conclude that △abc ≅ △dbc.
Required:
1. Show that angles ∠A and ∠D are equal.
2. Show that angles ∠B and ∠D are equal.
3. Show that sides AB and BD are equal.
Not Required:
1. Show that angles ∠C and ∠D are equal.
2. Show that sides AC and CD are equal.
To show that △abc ≅ △dbc,
we need to use the Side-Side-Side (SSS) Congruence Theorem. This theorem states that if three sides of one triangle are equal to the three corresponding sides of another triangle, then the two triangles are congruent.
Therefore, to show that △abc ≅ △dbc, we have to show that each corresponding side of the two triangles is equal. Additionally, we have to show that the angles opposite of the corresponding sides are equal. This can be done using the Angle-Angle-Side (AAS) Congruence Theorem. This theorem states that if two angles and the side between them in one triangle are equal to the same two angles and the side between them in another triangle, then the two triangles are congruent.
To show that △abc ≅ △dbc, we must show that angles ∠A and ∠D are equal, angles ∠B and ∠D are equal, and sides AB and BD are equal. The other steps (showing that angles ∠C and ∠D are equal and sides AC and CD are equal) are not required, since they are implied by the equal angles and sides already established.
Once all of these equalities have been established, we can conclude that △abc ≅ △dbc.

The talent show committee is anticipating selling 300 tickets to the talent show. They expect 180 adults to attend, and 120 children to attend. They hope to raise $1,440 from ticket sales to purchase classroom supplies. Adult tickets will be twice as expensive as child tickets. For what prices should the committee sell adult tickets and child tickets to the show?
Step-by-step explanation:
The committee should sell adult tickets for $10 and child tickets for $5 to raise $1,440 from ticket sales.
Let x be the price of adult tickets in dollars and y be the price of child tickets in dollars. We can set up the following system of equations to represent the given information:
x + y = 300 (the total number of tickets sold)
180x + 120y = 1440 (the total amount of money raised)
x = 2y (the price of adult tickets is twice the price of child tickets)
Substituting the third equation into the first equation, we get:
2y + y = 300
3y = 300
y = 100
Substituting this value for y into the third equation, we get:
x = 2*100
x = 200
Substituting these values for x and y into the second equation, we get:
180200 + 120100 = 1440
This equation is true, so the solution x = $200 and y = $100 is valid. Therefore, the committee should sell adult tickets for $10 and child tickets for $5 to raise $1,440 from ticket sales.

The domain and the slope are the same thing. To find slope you use the slope formula which is y2-y1 over x2-x1. Once you set up your equation you should get -4-(-3) over 1-0. When you solve it you should get -1/1 and -1 divided by 1 is -1. So then the slope is -1....

How long will it take to fill the pool if two hoses are used, one that fills at a rate of 40 gallons per hour and one that fills at a rate of 60 gallons per hour? 100 hours 150 hours 180 hours 200 hours.
It will take 180 Hours to fill the pool if both hoses are used.
In our question, one data is missing. You require the pool's volume or some information that enables you to calculate it. The same statement given by you is part of a problem where you know a series of data that shows the time required to fill the pool at different flow rates:
flow rate time
60 gal/h 300 h => 60 gal/h * 300 h = 18,000 gal
45 gal/h 400 h => 45 gal/h * 400 h = 18,000 gal
36 gal/h 500 h => 36 gal/h * 500 h = 18,000 gal
30 gal/h 600 h => 30 gal/h * 600 h = 18,000 gal
So for this pool to calculate (several times) that the volume is 18,000 gal.
You now possess two hoses, one of which has a flow rate of 40 gals per hour and the other of which has a flow rate of 60 gals per hour.
The total flow rate is the sum of the two flow rates"
total flow rate = 40 gal/h + 60 gal/h = 100 gal/h
And you just must divide the volume of the pool (18,000 gals) by the total flow rate (100 gal/h) to get the time to fill the pool:
time = volume / flow rate = 18,000 gal / 100 gal/h = 180 hours.
So, finally, our answer to fill the pool will be about 180 hours.
