Answer:

C

Step-by-step explanation:

The measure of angle BC of the triangle is given by BC = 130°

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔBCD , where it is isosceles

And , the measure of BC ≅ BD

where Isosceles triangle C B D has points on the circle.

The measure of arc CD = 100°

Now , arc length is twice the inscribed angle.

2 x ∠B = CD

2 x ∠B = 100

∠B = 100/2

∠B = 50

Now, in an isosceles triangle, the angle opposite to the equal sides must be equal.

The sum of the three angles must be 180.

x + x + 50 = 180°

2x = 180 - 150

2x = 130°

Hence , the measure of angle BC = 130°

Final answer:

Order of magnitude provides an estimation of the scale of a value expressed in powers of 10. For the number of states in the United States, the order of magnitude is approximately 10¹.

Explanation:

Order of magnitude refers to the scale of a value expressed in the metric system. Each power of 10 represents a different order of magnitude. For example, 10¹, 10², 10³ are all different orders of magnitude. We can estimate that the number of states in the United States is of the order of magnitude 10¹. This means there are approximately 10 to the power of 1 states in the United States.

Answer:

B. ΔABD, ΔADC, ΔDBC

Step-by-step explanation

Step -1 In ΔABD and ΔADC (from figure).

∠DAB=∠CAD (common in both triangles) ,

∠DBA=∠CDA =90 degree, and

∠BDA=∠DCA (rest angle of the two triangles).

therefore ΔABD similar to ΔADC (by AAA similarity theorem).

Step -2 In ΔDBC and ΔADC (from figure).

∠DCB=∠ACD (common in both triangles) ,

∠DBC=∠ADC =90 degree, and

∠CDB=∠CAD (rest angle of the two triangles).

therefore ΔDBC similar to ΔADC (by AAA similarity theorem).

Step -3 In ΔABD and ΔDBC (from figure).

∠BDA=∠BCD (because , ∠ACD=ADB from stap-1 and ∠ACD=∠BCD from figure) ,

∠DBA=∠CBD =90 degree, and

∠BAC=∠BDC (rest angle of the two triangles).

therefore ΔABD similar to ΔDBC (by AAA similarity theorem).

In the above step- ΔABD similar to ΔADC, ΔDBC similar to ΔADC and ΔABD similar to ΔDBC.

Hence ΔABD, ΔADC, ΔDBC similar to each other in the given figure.

Based on the diagram shown above, the three similar right triangles are: B. ΔABD, ΔADC, ΔDBC.

The Right Triangles Similarity Theorem states that when the altitude of a  triangle is drawn to the hypotenuse of a right angled triangle, then, the two triangles that are formed would be similar to each other, as well as the original triangle.

Based on triangles ABD and ADC, we can logically deduce the following congruent angles;

m∠DAB ≅ m∠CAD

m∠DBA ≅ m∠CDA = 90°

m∠BDA ≅ m∠DCA

ΔABD ~ ΔADC (AAA similarity theorem).

You didn't provide all the possible answers.  In this case we don't need to see all answers to help you... but because you didn't provide all the choices for answer, we can't give the exact answer, only the possible range of values.

The question asks for a possible taxable income for someone filing under the 28% bracket.

If we look at the table, we see the 28% bracket is for income ranging from $82,250 (exclusively) to $171,550 (inclusively)

So, your answer has to be within the range:

$82,250 < x <= $171,550

It cannot be $82,250 but it can be $171,550 and any number in between.

Since you didn't provide all the answer choices, we can't tell you if it's B, C, D, and so on... but we can tell you it's not A.

A new borrower cannot achieve a perfect credit score, but the number of points missed is not specific and varies individually. Fair credit decisions are based on facts, not personal attributes. Late payment fees and interest on carried balances also affect your credit score.

When you are building your payment history, it's essential to understand the impact of your actions on your credit score. A perfect credit score is typically seen as 850. As a new borrower, lacking a lengthy credit history, you may not have a perfect score, but the exact number of points you may miss cannot be precisely determined without considering individual credit activities. However, every lender has different criteria for evaluating credit scores, and it is fair practice that race, gender, religion, and other such attributes are not considered in credit scoring.

If you carry a credit card balance from month to month, you will incur interest charges, which can quickly accumulate and affect your credit utilization ratio, thereby potentially lowering your credit score. Promptly paying off credit card balances and keeping a low utilization rate are key strategies to maintain and improve your credit score.

Remember that late payments can result in additional charges, as in the case where a credit card company charges a $10 late fee and $5 daily until the payment is settled. Such penalties not only burden you financially but can also impact your credit score if late payments are reported to credit bureaus.

Final answer:

When starting to build your payment history, it's not possible to achieve a perfect credit score instantly due to the short credit history length and other factors. Payment history is the most significant component, affecting 35% of the FICO score. Keeping accounts in good standing and credit utilization under 30% are key steps to improving your score.

Explanation:

When you're building your payment history, establishing a perfect score immediately is not typically possible. A perfect FICO score is 850, and payment history is the most influential factor, accounting for 35% of your score. As a new credit user, your credit history length is shorter, which negatively affects your score. Unfortunately, it's not possible to quantify exactly how many points you'll miss from a perfect score as it varies depending on the individual credit report and the scoring model used.

It's important to keep your accounts in good standing to build a strong credit history over time. Also, being mindful of your Amounts Owed, which makes up 30% of the FICO score, can help improve your standing. Striving to utilize no more than 30% of your available credit is recommended. Over time, with good financial habits such as these, your credit score will naturally improve, moving closer to the ideal score of 700 or higher.

Other factors influencing your score include the length of your credit history (15%), new credit, and the mix of credit types you have. It's crucial to avoid opening too many new accounts at once, as this can lower your average account age and result in hard inquiries, both of which can reduce your score somewhat.

Answer:

f ^-1 (x) = 2x+28

Step-by-step explanation:

f(x) = 1/2x-14

Replace f(x) with y

y = 1/2 x -14

Exchange x and y

x = 1/2 y -14

Solve for y

Add 14 to each side

x+14 = 1/2 y -14+14

x+14 = 1/2 y

Multiply each side by 2

2(x+14)= 1/2 y*2

2x+28 = y

The inverse function is

f ^-1 (x) = 2x+28

Each x value has its own y value, so it is a function

Option D is correct. The inverse of the given function is a function since all the element in its co-domain has a unique element in the domain.

For a mapping to be called a function, it must have but the input values called the domain and the output values known as the co-domain.

All the domains must also have a corresponding co-domain, else it is not a function.

From the given mapping, we can see that all the values in the domain have corresponding values in the co-domain and vice versa(in the case of its inverse).

Hence we can conclude that the inverse of the given function is a function making other options incorrect.

The value of the expression 3/8 divided by 1 and 1/2 is calculated by converting the mixed number into an improper fraction, changing the division to multiplication by using the reciprocal, and simplifying the multiplication to get the final answer, which is 1/4.

The question is asking for the value of the mathematical expression 3/8 divided by 1 and 1/2. To solve this problem, first, we need to convert 1 and 1/2 into an improper fraction.  The result is 3/2. Next, we should remember that division by a number is the same as multiplication by its reciprocal. Therefore, we turn the equation into a multiplication problem by multiplying 3/8 by the reciprocal of 3/2, which is 2/3.

Solving this gives us the answer: (3/8) * (2/3) = 1/4. So, the value of the expression 3/8 divided by 1 and 1/2 is 1/4.
