Which of these expressions will give the unpaid balance after 7 years on a $60,000 loan with an apr of 8. 4%, compounded monthly, if the monthly payment is $516. 90?.

Answers

The option c will give the unpaid balance after 7 years on a $60,000 loan with an apr of 8. 4%, compounded monthly, if the monthly payment is $516. 90.

The profit you receive on money is known as compound interest. The interest that is calculated using both the principal and the interest that has accrued during the previous period is called compound interest.

For the given situation,

Principal value, p = $60000

Rate of interest, r = 8.4% = 0.084

Monthly payment, pm = $516.90

Number of years, T = 7 years

Compounded monthly, n= 12

The formula of unpaid balance on loan is

[tex]B = p\left(1+\frac{r}{n}\right)^{nT}+pm\left(\frac{1-\left(1+(r/n)^{nT}\right)}{r/n}\right)[/tex]

Now putting the values

[tex]B = 60,000\left(1+\frac{0.084}{12}\right)^{12\cdot 7}+516.90\left(\frac{1-\left(1+(0.084/12)^{12\cdot7}\right)}{0.084/12}\right)[/tex]

Simplifying

[tex]B = 60,000\left(1+0.007\right)^{84}+516.90\left(\frac{1-\left(1+0.007^{84}\right)}{0.007}\right)[/tex]

Hence, the option c is correct.

The unpaid balance after 7 years on a $60,000 loan with an APR of 8.4% compounded monthly, if the monthly payment is $516.90, is $1,163.53.

This can be calculated using the formula for future value of an annuity. The formula is FV = PMT(1 + i)^n - 1/i where FV is the future value, PMT is the periodic payment, i is the interest rate per period and n is the total number of payments.

Calculate the interest rate per period:

i = 0.084/12 = 0.0070

Calculate the total number of payments:

n = 7 * 12 = 84

Calculate the future value of the annuity:

FV = $516.90 (1 + 0.0070)^84 - 1/0.0070

FV = $516.90 (1.0070)^84 - 1/0.0070

FV = $516.90 (2.5408) - 1/0.0070

FV = $1,306.39 - 142.86

FV = $1,163.53

Therefore, the unpaid balance after 7 years on a $60,000 loan with an APR of 8.4% compounded monthly, if the monthly payment is $516.90, is $1,163.53.

13. The consecutive integers are -46 and -45

What is an equation?

An equation is a statement which indicates the equivalence between two expressions.

10. 18·y - 10 = 2 + 18·y

18·y - 18·y - 10 + 10 = 2 + 18·y - 18·y + 10

0 = 12

The equation 18·y - 10 = 2 + 18·y is a contradiction with no solution.

11. 2·(6·x - 4) - 16x = 4·(3·x - 2)

2·(6·x - 4) - 16x = 12·x - 8 - 16·x = -8 - 4·x

4·(3·x - 2) = 12·x - 8

2·(6·x - 4) - 16x = -8 - 4·x = 4·(3·x - 2) = 12·x - 8 therefore

-8 - 4·x = 12·x - 8

16·x = 0

x = 0 ÷ 16 = 0

x = 0

What is the measure of each base angle of an isosceles triangle if its vertex?

Answers

The measure of each base angle of an isosceles triangle is is 65 degree.

In an isosceles triangle, the two base angles are congruent, or equal in measure. To find the measure of one of the base angles, we can use the fact that the measures of the angles in a triangle always add up to 180 degrees. This means that if we know the measure of the vertex angle, we can use this information to find the measures of the base angles.

we have an isosceles triangle with a vertex angle that measures 50 degrees. To find the measure of a base angle, we can use the following formula:

(180 - measure of vertex angle)/2 = measure of base angle

Plugging in the given value of 50 degrees for the measure of the vertex angle, we get:

(180 - 50)/2 = measure of base angle

Solving this equation, we find that the measure of a base angle is 65 degrees. Therefore, if the vertex angle of an isosceles triangle measures 50 degrees, the measure of a base angle is 65 degrees.

A line has a slope of 6 and includes the points (-7, v) and (-4, 9). What is the value of v?

Please help me!

I really want to have time to study for my unit test tomorrow.

Answers

Answer:

To solve this problem, we can use the formula for the slope of a line: slope = (y2 - y1)/(x2 - x1).

Plugging in the given values, we get: slope = (9 - v)/(-4 - (-7)).

We can simplify this to: slope = (9 - v)/3.

Since the slope is given as 6, we can set this expression equal to 6 and solve for v:

6 = (9 - v)/3

Multiplying both sides by 3 gives us: 18 = 9 - v

Adding v to both sides gives us: 18 + v = 9

Subtracting 9 from both sides gives us: v = 9 - 18

Finally, we can simplify this to: v = -9

So the value of v is -9.

Answer:

-9

Step-by-step explanation:

(9 - v)/(-4+7)= 6

9 - v = 18

-v = 9

v = -9

If the measure of interior angle of a regular polygon is 108°,then find the number of sides.​

Answers

Answer: If the measure of interior angle of a regular polygon is 108°,then the number of sides are 5.

Step-by-step explanation:

Given:

108° equals one internal angle of a regular polygon.

The sum of an regular polygon's internal angles = (n - 2) 180°.

The interior angle of a regular polygon equals [(n - 2) 180°] divided by n.

By equating them, we obtain

108 = [(n - 2) × 180°]/n

By additional simplification

108n = 180n - 360

180n - 108n = 360

So we get

72n = 360

n = 5

Therefore, it is a pentagon, a polygon with five sides.

Are there 4 types of task analysis?

Answers

In general, there are five kinds of task analyses:

job or performance analysis learning analysis cognitive task analysis content or subject matter analysis activity analysis

What is Task Analysis

Task analysis is the process of learning about ordinary users by observing them in action to understand in detail how they perform their tasks and achieve their intended goals. Tasks analysis helps identify the tasks that your website and applications must support and can also help you refine or re-define your site’s navigation or search by determining the appropriate content scope.

Purpose of Task Analysis

In their book User and Task Analysis for Interface Design, JoAnn Hackos and Janice Redish note that performing a task analysis helps you understand:

What your users’ goals are; what they are trying to achieveWhat users actually do to achieve those goalsWhat experiences (personal, social, and cultural) users bring to the tasksHow users are influenced by their physical environmentHow users’ previous knowledge and experience influence:How they think about their workThe workflow they follow to perform their tasks

In a game involving a standard deck of 525252 playing cards, an individual randomly draws 777 cards without replacement. Let y=y=y, equals the number of kings drawn. Is yyy a binomial variable? why or why not?.

Answers

For y = the number of kings drawn,  y a binomial variable

In this question we have been given that in a game involving a standard deck of 52 playing cards, an individual randomly draws 7 cards without replacement.

Also, y represents the number of kings drawn

We need to determine whether y a binomial variable or not.

y = "number of kings drawn"

We know that in the standard deck of 52 playing cards there are 4  King cards(each from the 4 suits:; Diamonds, Clubs, Hearts, Spades)

If we draw 7 cards from a standard deck of 52 playing cards, there would be 5 possible values of y.

y = 0     (there would be no king card)

y = 1      (there would be 1 king card)

y = 2     (there would be 2 king cards)

y = 3     (there would be 3 king cards)

y = 4     (there would be 4 king cards)

We know that a binomial variable is a variable that represents two outcomes.

Assume that x = "drawing a king" 7 times, then x is a binomial variable, because it has two outcomes, or you draw a king, or you don't.

Also, as we know a binomial variable can also represent the number of outcomes of each type for several events.

Hence, y is a binomial variable.

No, yyy is not a binomial variable. A binomial variable is a discrete random variable that follows a binomial distribution and has two possible outcomes - success and failure.

In this case, yyy is not a binary outcome, since it can take on any number from 0 to 777.

To calculate the probability of yyy, we can use the formula P(y) = (n! / ((n-y)!*y!)) * (p^y * (1-p)^(n-y)), where n is the total number of trials (in this case, 777), y is the number of successes (in this case, number of kings), and p is the probability of success (in this case, 4/52). Therefore, the probability of drawing yyy kings from 777 cards is:

P(y) = (777! / ((777-y)!*y!)) * ((4/52)^y * ((48/52)^(777-y))

For example, if y=3, then the probability of yyy is:

P(3) = (777! / (774!*3!)) * ((4/52)^3 * ((48/52)^(774))

= 0.00307%

Imagine that the stone is part of an arch, and that there is an isosceles triangle JEF formed by extending sides GE and HF downward.

Use the measure of the angles of the trapezoid to find to measure of the base angles JEF and JFE. Add these measurements to your drawing

(USE PICTURED TO HELP ANSWER THE PROBLEM)

Answers

The measure of the base angles of the isosceles triangle ∠JEF and ∠JFE are;

m∠JEF = m∠JFE = 80°

What is an isosceles triangle?

An isosceles triangle is a triangle that has a pair of congruent sides and a pair of congruent angles.

The trapezoid in the question, based on the drawing in a similar online question, is formed by dividing the semicircular arc into 9 smaller (congruent) arcs.

The number of arcs the semi circular arc is divided by the dimensions and radial location of the stone = 9

The vertex angle of each isosceles triangle = 180° ÷ 9 = 20°

The measure of the base angles of the triangle ΔJEF = (180° - 20°) ÷ 2 = 80°

The base angles of the isosceles triangle ΔJEF = ∠JEF and ∠JFE

The measure of the base angles of the isosceles triangle are;

m∠JEF = m∠JFE = 80°

Fair tickets for 2 adults and 3 children cost $34. An adult ticket costs $2 more than a child ticket. What is the price of an adult ticket

Answers

The price of an adult ticket is $8.

An algebraic expression is the combination of numbers and variables in expressing and solving a particular mathematical question.

Let x = price of an adult ticket

If an adult ticket costs $2 more than a child ticket, then

price of a child ticket = x - 2

If fair tickets for 2 adults and 3 children cost $34, then

2x + 3(x - 2) = 34

Simplify the equation and solve for the value of x.

2x + 3(x - 2) = 34

2x + 3x - 6 = 34

5x = 40

x = 8

price of an adult ticket = $8

price of a child ticket = x - 2 = $6

Hence, the price of each ticket is $8 and $6 for adult and child, respectively.
