The value of the investment will be lesser by $26325.30 $25657.08 $668.22 $26325.30 −$25657.08 = $668.22 if the interest is compounded daily rather than annually.
What's composite interest?
emulsion interest is the interest you earn on interest. This can be illustrated by using introductory calculation if you have$ 100 and it earns 5 interest each time, you will have$ 105 at the end of the first time. At the end of the alternate time, you will have$110.25.emulsion interest is calculated by multiplying the original loan quantum, or star, by the bone plus the periodic interest rate raised to the number of emulsion ages minus one. This will leave you with the total sum of the loan including emulsion interest.It's calculated by multiplying the first star quantum by one and adding the periodic interest rate raised to the number of emulsion ages abate one. The total original quantum of your loan is also abated from the performing value. P is top, I is the interest rate, n is the number of compounding ages.The investment compounded annually will be worth $16,640 after 16 years, while the investment compounded periodically with 4 interest periods per year will be worth $16,383.84.
To calculate the investment compounded annually, we can use the formula:
A = P * (1 + r/n)^(nt)
where:
A = the future value of the investment
P = the principal amount (i.e., the initial deposit)
r = the annual interest rate as a decimal
n = the number of times the interest is compounded per year
t = the number of years the money is invested for
So for this example, we would have:
A = $10,000 * (1 + 0.04)^(16) = $16,640
For the investment compounded periodically, the formula is a little different:
A = P * (1 + r/n)^(nt)
where:
A = the future value of the investment
P = the principal amount (i.e., the initial deposit)
r = the annual interest rate as a decimal
n = the number of times the interest is compounded per year
t = the number of years the money is invested for
So for this example, we would have:
A = $10,000 * (1 + 0.04/4)^(4 * 16) = $16,383.84
As you can see, the investment compounded annually is worth slightly more than the investment compounded periodically with 4 interest periods per year.

Lincoln invested $6,500 in an account paying an interest rate of 3^3/4%
compounded quarterly. Savannah invested $6,500 in an account
paying an interest rate of 4^1/8% compounded continuously. After 20
years, how much more money would Savannah have in her account
than Lincoln, to the nearest dollar?
Answer:
To the nearest dollar, Savannah would have $8,007 more in her account than Lincoln.
Step-by-step explanation:
To find out how much more money Savannah would have in her account than Lincoln after 20 years, we need to calculate the future value of both investments using the appropriate interest rate and compounding period.
For Lincoln's investment:
Future value = $6,500 * (1 + (3^3/4/100) / 4)^(4*20) = $6,500 * (1 + 0.046875)^80 = $6,500 * 2.611 = $16,917.50
For Savannah's investment:
Future value = $6,500 * e^(0.041875*20) = $6,500 * 3.843 = $24,924.50
To find the difference between the two investments, we can subtract Lincoln's future value from Savannah's:
$24,924.50 - $16,917.50 = $8,007
To the nearest dollar, Savannah would have $8,007 more in her account than Lincoln.

Divide the following polynomials using synthetic division, then place the answer in the proper location on the grid. Write answer in descending powers of x.
(x4 + 81) / (x + 3)
The division of the given polynomial would be (x^4) + 81.
What is the synthetic division?
Synthetic division is a method for dividing polynomials that allows you to divide a polynomial by a linear factor (a factor in the form of (x-c) where c is a constant) without actually performing the long division process. It is a short cut method that simplifies the process of dividing polynomials.
To divide the polynomials using synthetic division, we will use the following steps:
Write the polynomials in descending order of exponents. In this case, the given polynomials are already in descending order:
(x^4+ 81) / (x + 3)
Create a grid with the dividend on the left and the divisor on the right.
x^4 81
x 3
Bring down the leading coefficient of the dividend, which is x^4 in this case. Write it in the next row of the grid.
x^4 81
x^4 x 3
Multiply the divisor (x + 3) by the leading coefficient (x^4) and write the result in the next row.
x^4 81
x^4 x 3
x^5 x^5 3x^4
Subtract the second row from the third row and write the result in the next row.
x^4 81
x^4 x 3
x^5 x^5 3x^4
0 81-3x^4
Bring down the next coefficient of the dividend (81) and write it in the next row of the grid.
x^4 81
x^4 x 3
x^5 x^5 3x^4
0 81-3x^4
81
Now we repeat the steps 4-6 for the rest of the coefficients of the dividend, but there is no more coefficients in this example.
The quotient is x^4 and the remainder is 81
So the final answer is:
(x^4)+(81)
Hence, the division of the given polynomial would be (x^4) + 81.

Answer:
360 kilometres
Step-by-step explanation:
To find the distance a car would have to cover if it has been traveling for four and a half hours, you can use the formula:
distance = speed x time
In this case,
distance = 80 km/hour x 4.5 hours
To calculate the distance in kilometers, we multiply the speed in kilometers per hour by the time in hours.
distance = 80 x 4.5
distance = 360 kilometers
So, the car would have to cover 360 kilometers if it has been traveling for four and a half hours at 80 km/hour.
NO is dilated by a scale factor of to form N'O'. NO measures 40. What is the

N'O' is a transformation of NO. The measurement of N'O' is 30.
What is a line segment?
A line segment is a section of a straight line that is bounded by two distinct end points and contains every point on the line between them. The Euclidean distance between the endpoints of a line segment determines its length.
A scale factor is defined as the ratio of the scale of a given original object to the scale of a new object that is its representation but of a different size (bigger or smaller). For example, we can enlarge a rectangle with sides of 2 cm and 4 cm by multiplying each side by a number, say 2.
Given that NO is dilated by a scale factor of 3/4 to form N'O'.
The length of NO is 40.
To find the length of N'O', multiply the scale factor by the length of NO.

find the value of x in both examples
For 1, since the exponential decay formula is a*(1-r)^x, a is still the same as the base value and r would replace 1-r with r being the decay rate, so r would be 1-the decay rate.
For 2, applying that formula, getting 52500*(1-2.5%)^10 (because it's for 10 years and compounded annually). Since 100% is 1, 2.5% is 0.025, and
1-0.025=0.975. Putting that in, we get 52500*(0.975)^10=around 40757 people.
For inverse functions, what we do is have y=2x+1, so we switch x and y and solve for y, so in x=2y+1 we subtract one from both sides to get x-1=2y. Next, dividing both sides by 2, we get (x-1)/2=y as our inverse. Since we want positive integers less than 10, (x-1) has to be even and therefore x has to be odd. Hence, we get that x can be 9 while y can be 4 for (9, 4)

Answer: Tina has read 16 pages and reads 22 pages per day until the book is finished.
Zuri has read 24 pages and reads 18 pages per day until the book is finished.
We can use this information to set up an equation to represent the number of pages read by each student over a certain number of days.
Let's call the page number they are on when they read the same amount of the book "p"
We can set up the equation as follows:
16 + 22d = 24 + 18d = p
Now we can solve for p by combining like terms:
16 + 22d = 24 + 18d
4d = 8
d = 2
Now we know that it takes 2 days for Tina and Zuri to read the same amount of the book.
Now we can use this value of d to find out what page they are on when they read the same amount of the book.
p = 16 + 22*2 = 16 + 44 = 60
So Tina and Zuri are on page 60 when they have read the same amount of the book.

the interest the bond paid off is $7507.8125.
What is simple interest?
A quick and simple way to figure out interest on money is to use the simple interest technique, which adds interest at the same rate for each time cycle and always to the initial principal amount. Any bank where we deposit our funds will pay us interest on our investment. One of the different types of interest charged by banks is simple interest. Now, before exploring the idea of basic curiosity in further detail,
The formula for simple interest is:
S = p*t*r/100
where P is the principal amount of money, R is the interest rate as a decimal, T is the time.
a bond that paid 7.75% simple interest earned $3,875 interest.
S = (3875*7.75*25)/100 = $7507.8125
Hence the interest the bond paid off is $7507.8125.

A game room has a floor that is 450 feet by 20 feet. A scale drawing of the floor on grid paper uses a scale of 1 units feet. What are the dimensions of the scale drawing? Enter your answer as length by width. The scale drawing is units by units.
A scale drawing is a representation of an object or space that is reduced or enlarged in proportion to the actual object or space. In this case, the scale of the drawing is 1 unit = 1 foot. To find the dimensions of the scale drawing, we need to divide the actual dimensions of the room by the scale of the drawing.
The actual dimensions of the floor are 450 feet by 20 feet.
So, the dimensions of the scale drawing are:
450 feet / 1 unit = 450 units (length)
20 feet / 1 unit = 20 units (width)
Therefore, the dimensions of the scale drawing are 450 units by 20 units. So, the scale drawing is 450 by 20.

m ∠PQS = 3x + 5
m ∠SQR= 2x + 25
Setting these expressions equal to each other:
3x + 5 = 2x + 25
Subtract 2x from both sides
3x - 2x + 5 = 25
x + 5 = 25
Subtract 5 from both sides
x = 20
Therefore m ∠PQS which is 3x + 5:
m ∠PQS = 3(20) + 5 = 65°
m ∠SQR = ∠PQS =65° also
Adding the two together we get
m ∠PQR = 65 + 65 = 130°

Let w=2+i and z be nonzero complex number. If the argument of z is pi/4 and |x-w| =sqrt(5) , what is | z |^2
Answer:
Step-by-step explanation:
?
|z|^2 = |z|*|z| = (|z|)^2
Since the argument of z is pi/4, z can be written as z=r*(cos(pi/4)+i*sin(pi/4)) where r is the magnitude of z.
We also know that |x-w| =sqrt(5).
This means that |z-w| = sqrt(5).
Substituting the expression for z, we get:
|r*(cos(pi/4)+i*sin(pi/4))-w| = sqrt(5)
Simplifying this equation, we get:
|r-2-i| = sqrt(5)
Squaring both sides, we get:
(r-2-i)(r-2+i) = 5
Simplifying, we get:
r^2-4+i(2r-2)=5
Equating the real and the imaginary parts, we get:
r^2-4 = 5
and
2r-2=0
Solving these equations simultaneously, we get:
r = sqrt(9)
Therefore,
|z| = sqrt(9)
Hence,
|z|^2 = (sqrt(9))^2 = 9
