Find the present value​ (the amount that should be invested now to accumulate the following​ amount) if the money is compounded as indicated.
​$6800 at ​4% compounded quarterly for 3 years

Answers

The present value​ the amount that should be invested now to accumulate is $7662.24.

What is meant by compound interest?

Compound interest is the adding of interest to the principal amount of a loan or deposit, or interest on interest + principal. It is the outcome of reinvesting interest, or adding it to lent capital, rather than paying it out or requesting payment from the borrower, so that interest is received on the principle sum plus previously accumulated interest in the next month. In finance and economics, compound interest is common.

Compound interest differs from simple interest in that previously collected interest is not added to the current period's main amount, resulting in no compounding. The simple annual interest rate is calculated by multiplying the interest amount per period by the number of periods in a year.

Given,

Principle P=$6800

T=3 years

And also given that the money is compounded quarterly.

Present value=P[tex](1+(R/4)^{4t}[/tex]

=6800[tex](1+(4/400)^{12}[/tex])

=6800[tex](1+(1/100))^{12}[/tex]

=6800[tex](101/100)^{12}[/tex]

=6800[tex](1.01)^{12}[/tex]

=6800×1.1268

=$7662.24

The present value​ the amount that should be invested now to accumulate is $7662.24

A fence is to be built to enclose a rectangular area of 1250 square feet. The fence along three sides is to be made of material that costs $6 per foot. The material for the fourth side costs $18 per foot. Find the dimensions of the rectangle that will allow for the most economical fence to be built

Answers

The dimensions of the rectangle for the most economical fence are length, L = 50 feet and width, W = 25 feet

How to find the dimensions of the rectangle for the most economical fence?

Given: Area =  1250 square feet, , cost of material along three sides = $6 per foot, cost of material for fourth sides = $18 per foot

In order to calculate the dimension of the fence

Let L and W represent the length and width of the fence respectively

Thus, the area of the fence can be represented as:

A = L × W = 1250  ---- (1)

L = 1250/W

Let the total cost to construct the fence be 'C' can be obtained if we construct the shorter side with material with a cost of $18 per foot

C = 6×(2W + L) + 18×L

C = 12W + 24L  ---- (2)

Substituting the value of L from equation 1 into equation 2 we have:

C = 12W + 24×(1250/W)

To minimize the cost we differentiate both sides with respect to W and equate the result to zero:

C = 12W + 24×(1250/W)

dC/dW = d/dW (12W + 30000/W)

0 = 12 - 30000/W²

12W² = 30000

W² = 2500

W = 50 feet

Since L = 1250/W

L = 1250/50

L = 25 feet

Therefore, the dimensions of the rectangle are length of 25 feet and width of 50 feet

Susan has a collection of 60 nickels and dimes. If the number of nickels is four times the number of​ dimes, how many nickels and how many dimes does she​ have?

Answers

Answer: 12 dimes, 48 nickles.

Step-by-step explanation:

Let x = the number of dimes

Let 4x = the number of nickels

x + 4x = 60

5x = 60

x = 12 dimes

4x = 48 nickles

She has 48 nickels and 12 dimes.

Equation

At first, we have to express the sentence into equation:

Given:

x = nickels

y = dimes

Susan has a collection of 60 nickels and dimes  --> x + y = 60 ............. (1)

the number of nickels is four times the number of dimes --> x = 4y ......(2)

then we must input the equation (2) into the equation (1):

x + y = 60

4y + y = 60

5y = 60

y = 60/5

y = 12

As we know the value of y, we can calculate the value of x from the equation (2):

x = 4y

x = 4 * 12

x = 48

Thus, Susan has 48 nickels and 12 dimes

The x-intercept is (5,0)

The y-intercept is (0,10)

What is intercept ?

A y-intercept, also known as a vertical intercept, is the point where the graph of a function or relation intersects the y-axis of the coordinate system in analytical geometry, using the widely used convention that the horizontal axis represents a variable x and the vertical axis represents a variable y. As a result, x = 0 is satisfied at these sites.

A line's x-intercept and y-intercept are the points at which the x- and y-axes cross, respectively.

To find x-intercept we put y = 0 to the equation

4x + 2y = 20

4x = 20

x = 5

To find y-intercept we put x = 0 to the equation

4x + 2y = 20

Here the detail

The formula for rectangled-shaped area is multiply length and width

Area = Length x Width

In this case, we know that the area is 36.25 ft2 and the width is 5 feet

so we can divided the area and the width to solve the length

Area = Length x Width

36.25 = Length x 5

Length = 36.25 : 5

In an animal rescue facility are 21 animals.14 cats and 7 dogs. During the day 5 animals were adopted.what is the probabity that 3 cats and 2 dogs were adopted? Review ch 7 on probability

Answers

Answer:

0.3756

Step-by-step explanation:

I believe this is a combinatorics probability problem.

We first figure out in how many ways we can choose 3 cats out of 14 cats

Then we figure out how many ways we can choose 2 dogs out of 7 dogs

The total number of ways to select 3 cats and 2 dogs will be the product of these two

We then figure out in how many ways we can select 5 animals out of a total of 21 animals

The product we computed divided by the above number will give the probability

The number of ways we can choose k items out of n items is given by nCk i.e n Choose k

The formula is rather complicated but almost all calculators should be able to compute this given n and k

Let's deal with the selection of 3 cats from the population of 14 cats

This is given by 14C₃ which works out to 364

Number of ways for selecting 2 dogs from 7 dogs = 7C₂ = 21

Number of ways of selecting 5 animals from 21 = 21C₅ = 20349

The probability of selecting 3 cats and 2 dogs is therefore:

[tex]\dfrac{364 \times 21}{20349} = 0.3756[/tex]

That, I believe is the answer. Please let me know if it is correct and if you need more info.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example: 2x + 4 = 5 is an equation.

We have,

Cost of each chair = x

Cost of each table = y

Now,

2x + 6y = 54 _____(1)

5x + 3y = 36 ______(2)

From (1) we get,

2x = 54 - 6y

x = (54 - 6y)/2 ______(3)

Now,

Putting (3) in (2) we get,

5(54 - 6y)/2 + 3y = 36

270/2 - 30y/2 + 3y = 36

135 - 15y + 3y = 36

99 = 12y

y = 99/12

y = 8.25 ______(4)

Now,

Putting 4 in (3) we get,

x = (54 - 6 x 8.25) / 2

x = 4.5/2

x = 2.25

Thus,

The cost of each chair is $2.25.

The cost of each table is $8.25.
