Step-by-step explanation:

w=241(1.06)^11=457 million

Solution

For this case we can begin dividing both sides by 3500 and we got:

then we can take square root in both sides and we got:

And finally we can subtract 1 in both sides and we got:

and if we multiply by 100 we got:

r= 6.797 and rounded the answer would be:

6.8%

Answer:

b: 8

Step-by-step explanation:

with dilating by 2, the B' figure would be bigger than B

because 4*2 = 8

Answer:

  C.  142°

Step-by-step explanation:

You want the angle between vectors u=3i+√3j and v=-2i-5j.

There are a number of ways the angle between the vectors can be found. For example, the dot-product relation can give you the cosine of the angle:

  u•v = |u|·|v|·cos(θ) . . . . . . where θ is the angle of interest

You can find the angles of the vectors individually, and subtract those:

  u = |u|∠α

  v = |v|∠β

  θ = α - β

When the vectors are expressed as complex numbers, the angle between them is the angle of their quotient:

  \(\dfrac{\vec{u}}{\vec{v}}=\dfrac{|\vec{u}|\angle\alpha}{|\vec{v}|\angle\beta}=\dfrac{|\vec{u}|}{|\vec{v}|}\angle(\alpha-\beta)=\dfrac{|\vec{u}|}{|\vec{v}|}\angle\theta\)

This method is used in the calculation shown in the first attachment. The angle between u and v is about 142°.

A graphing program can draw the vectors and measure the angle between them. This is shown in the second attachment.

__

Additional comment

The approach using the quotient of the vectors written as complex numbers is simply computed using a calculator with appropriate complex number functions. There doesn't seem to be any 3D equivalent.

The dot-product relation will work with 3D vectors as well as 2D vectors.

Answer:

a) 7

b) -1

c) 9

Step-by-step explanation:

a) Substitute -1 into the x's of the function.

f(-1) = -5(-1) + 2

f(-1) = 5 + 2

f(-1) = 7

b) f^-1(7) means: find the inverse of the function with 7 substituted as x.

Let y = f(x)

y = -5x + 2

5x = 2 - y

x = 2 - y / 5

f^-1(x) = 2 - x / 5

f^-1(7) = 2 - 7 / 5

f^-1(7) = -5/5

f^-1(7) = -1

c) We have already found the inverse of the- original function. Substitute -43 into the x's of the inverse function.

f^-1(-43) = 2 - (-43) / 5

f^-1(-43) = 2 + 43 / 5

f^-1(-43) = 45/5

f^-1(-43) = 9

1. so you have $114

weekdays weekends

18. 21

just divide 114 by 18 and 21

114÷18 = 6.3 which means 6 tickets

and 114÷ 21 = 5.4 which gives us 5 tickets

so the answer is

for weekdays the max ticket number I can get is 6 and for weekends is 5

2. we do the same method as above

for the lawn ( weekdays) seat we get 20 tickets

and for the lower box (weekend) we get 6 tickets max.

3. bleachers weekend seats = 20 tickets

line box weekday seats = 19 tickets

4. both of them can give exactly 7 tickets

After conducting a t-test for independent means, if you reject the null hypothesis, you are indicating that those two means are significantly different from each other. Hence option A is  the answer.

What is a t-test?

A t-test for independent means is a statistical test that compares two groups' means. The null hypothesis holds that there is no substantial difference between the means of the two groups, whereas the alternative hypothesis holds that there exist a significant difference between the mean of the two groups.

If the t-test rejects the null hypothesis, this implies that there is sufficient evidence to imply that the means of the two groups differ considerably.

In other words, the observed disparity in means is unlikely to be coincidental. The t-statistic and its accompanying p-value can be used to identify the amount and direction of the difference.

We can see that in the question they are indicating that the two means are having significant difference from each other. So the answer is to reject the null hypothesis.

Answer:

x: 8.75

y: 8.5

Step-by-step explanation:

Since the two triangles are similar, you can find the scale of LJK relevant to TRS by dividing 7/4 = 1.75

This means each side of LJK is 1.75 times greater than the respective side of TRS

Now you can plug this in to the other two sides by doing 5*1.75=8.75 and 6*1.75=10.5

This solves x, but since side LK is y+2, y is 10.5-2=8.5

x=8.75

y=8.5

Since the provided equation is inconsistent, it cannot intersect.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. When this equation is solved, we discover that the value of the variable x is 7.

Here,

we can see that the second set of equation,

4x+2y=12

20x+10y=30

4/20=2/10≠12/30

1/5=1/5≠2/5

So, the fraction of his original marbles he has left as a fraction is 3/7

The Difference in the amounts that Tsion and Ibrahim paid for their watches is £3.85.

To find the difference in the amounts that Tsion and Ibrahim paid for their watches, we need to convert the prices to the same currency. We can use the exchange rates given to convert both prices to pounds.

1 Singapore dollar = £0.58

72 Singapore dollars = 72 x £0.58 = £41.76

1 Hong Kong dollar = £0.09

399 Hong Kong dollars = 399 x £0.095 = £37.91

Therefore, Tsion paid £41.76 for the watch and Ibrahim paid £37.91 for the same model of watch.

To find the difference in the amounts paid, we can subtract the smaller amount from the larger amount:

£41.76 - £37.91 = £3.85

Therefore, the difference in the amounts that Tsion and Ibrahim paid for their watches is £3.85.

The purpose of an entity-relationship (ER) diagram is to visually represent the structure and relationships between entities in a database system.

An entity-relationship diagram is a visual representation that uses various symbols and connectors to depict entities, attributes, and the relationships between them. It is commonly used in database design to model and understand the organization and interactions of data within a system.

Here are the key purposes of an ER diagram:

Entity Representation: An ER diagram helps identify and define entities, which are objects or concepts with distinct characteristics. Entities are represented as rectangles in the diagram, and their attributes are depicted within the rectangles.

Relationship Representation: The diagram illustrates the relationships between entities, showcasing how they are connected or associated. Relationships can be one-to-one, one-to-many, or many-to-many, and they are depicted using different connectors and cardinality indicators.

Data Modeling: ER diagrams provide a blueprint for designing databases by visually representing the structure and organization of data. They help database designers determine the appropriate tables, attributes, and relationships needed to store and retrieve information efficiently.

Communication and Documentation: ER diagrams serve as a communication tool between stakeholders, such as developers, designers, and clients. They provide a clear and concise visual representation of the database structure, making it easier for everyone involved to understand and discuss the system requirements.

The primary purpose of an entity-relationship diagram is to visually represent the entities, attributes, and relationships within a database system.
