Amber invest $1,000 for 10 years compounded daily. Jin invests $1,000 for 10 years compounded continuously. If both investments are made at 8% interest rates, determine each of the following. Amber has a total of $ after 10 years. Jin has a total of $ after 10 years. So earns $ more interest.​

Answers

Compound interest is the interest that is compounded daily, weekly, monthly, annually e.t.c on a loan, investment, or an amount of money kept in a financial institution.

Amber has a total of $2,225.35 after 10 years. Jin has a total of $ 2,225.54 after 10 years. So earns Jin $0.19 more interest.​

For Amber:

The formula to find the amount compounded daily after 10 years is:

A = P(1 + r/n)nt

Where

P = Principal ( Initial amount) = $1000

R = Interest rate = 8%

n = Number of times interest is compounded = Daily = 365 days

t = Time in years = 10 years

First, convert R as a percent to r as a decimal

r = R/100

r = 8/100

r = 0.08 rate per year,

Then solve the equation for A

A = P(1 + r/n)^nt

A = 1,000.00(1 + 0.08/365)^(365x10)

A = 1,000.00(1 + 0.000219178)^(3650)

A = $2,225.35

The interest for Amber is:

P (principal) = $1,000.00

A( Amount) = $2,225.35

I (interest) =  P - A

= $$2,225.35 - $1,000.00

= $1,225.35

For Jin

The formula to find the amount compounded continuously after 10 years is:

A = Pe^rt

Where

P = Principal ( Initial amount) = $1000

R = Interest rate = 8%

n = Number of times interest is compounded = Continuously

t = Time in years = 10 years

First, convert R as a percent to r as a decimal

r = R/100

r = 8/100

r = 0.08 rate per year,

Then solve the equation for A

A = Pe^rt

A = 1,000.00(2.71828)^(0.08)(10)

A = $2,225.54

The interest for Jin is:

P (principal) = $1,000.00

A( Amount) = $2,225.54

I (interest) =  P - A

= $$2,225.54 - $1,000.00

= $1,225.54

Comparing the interest for both Amber and Jin, we find the difference to know who earns more.

Jin's interest - Amber's interest

= $1,225.54 - $1,225.35

= $0.19

Jin earns more interest.

Therefore, Amber has a total of $2,225.35 after 10 years. Jin has a total of $ 2,225.54 after 10 years. So earns Jin $0.19 more interest.​

In a study of the television viewing habits of children, a developmental psychologist selects a random sample of 300 first graders - 100 boys and 200 girls. Each child is asked which of the following TV programs they like best: The Lone Ranger, Sesame Street, or the Simpsons.

Complete the following table:

Answers

Answer:

20, 50, 70, 110

Step-by-step explanation:

boys x simpsons: 20

girls x long ranger: 50

girls x simpsons: 70

total x sesame street: 110

have a great day :)

20 girls watch Long Ranger , 110 first graders watch Sesame Street , 20 boys watch Simpsons, and 70 girls watch Simpsons.

What is random sampling?

" Random sampling is a process of observing samples using such technique that each sample has equal probability."

According to the question,

As per the information of random samples given in the table,

Total number of boys are  = 100

Total number of girls = 200

For boys

Long Ranger + Sesame Street + Simpsons = 100

⇒  50 + 30 + Simpsons = 100

Number of boys view Simpsons = 100 - 80

                                                          = 20

In Long  ranger column,

50 Boys + ___girls = 100

Number of girls watching Long Ranger = 100 -50

                                                                   = 50

In Sesame street

30 boys + 80 girls = 110 Total viewers

Number of girls watching Simpsons = 90 -20

                                                            = 70

Hence, 20 girls watch Long Ranger , 110 total boys and girls watch Sesame Street , 20 boys watch Simpsons, and 70 girls watch Simpsons.

Car A is traveling east at a steady speed of 60 miles per hour after 2 hours, it is 130 miles east of Johnstown. car B is traveling east on the same road. its distance east of Johnstown is represented by the graph.
Please help!

Answers

Answer: A

Step-by-step explanation:

Car B was 10 miles east of car A.

What is speed?

The rate of change of position of an object in any direction is called speed.

What is the relation between speed, distance and time?

[tex]speed = \frac{distance}{time}[/tex]

According to the given question

Speed of car A was 60 miles/hour.

⇒ After 2hours the distance covered by car A = 60 × 2 = 120 miles.

But it is given that car travelled total 130 miles.

So, the extra distance covered by the car = 130 - 120 = 10 miles.

From the graph we can say that the distance.

At, Time = 0

The distance travelled by car B is 20 miles.

Now, the extra distance covered by the car A w.r.t B = 20 - 10 = 10 miles

Since, both the cars were travelling in east direction.

Therefore, Car B was 10 miles east of car A.

So the angle measures are
95 and 95

Answer:

x = 11 --> angles = 95 degrees

Step-by-step explanation:

They are equal to each other so

7x + 18 = 8x + 7

Put the like terms together

18 - 7 = 8x - 7x

11 = x

so when we substitute this value of x into the equations, we get that both angles are 95 degrees.

Find the value of tan 6720 with out calculator

Answers

The best thing I can say is use a online scientific calculator.

Answer:

[tex]\sqrt3[/tex]

Step-by-step explanation:

I'm assuming you're dealing with degrees.

If that's the case, then I would first find the closest multiple of 360 to that number.

360*20 = 7200, which is a bit too high; 360*19 = 6840, still a bit too high; 360*18 = 6480, perfect.

Now, just subtract 6480 from 6720 and you will get 240.

The answer is now simplified to tan 240, which can be expressed as sin(240)/cos(240).

240 degrees is 30 degrees away from 270, creating a 30-60-90 triangle.

That means cos(240) is -1/2 and sin(240) is -sqrt(3)/2.

Now, just divide:

[tex]-\frac{\sqrt3}{2}/-\frac{1}{2} = -\frac{\sqrt3}{2}\cdot-2 = \sqrt{3}[/tex]

Therefore, tan(6720 degrees) = [tex]\sqrt3[/tex]
