Part a: Future amount due on a compound interest loan is $12271.78.
Part b: The amount due on the loan would be $12033.64, if the compounding period is increased to monthly.
Explain the term compounding?Compounding is the method through which interest is added to both the principle balance already in place and the interest that has already been paid. Thus, compounding can be thought of as interest on interest, with the result that returns on interest are magnified over time, or the so-called "magic of compounding."The formula for compounding is:
A = P(1 + r/100n)∧nt
P = $12,000
r = 0.07
Part a: compounded semiannually.
t = 4 years.
n = 2
A = 12000(1 + 0.07/100*2)∧2*4
A = 12000*1.00280
A = 12271.78
Thus, future amount due on a compound interest loan is $12271.78.
Part b:
t = 4 years.
n = 12
A = 12000(1 + 0.07/100*12)∧12*4
A = 12000*1.0028038
A = 12033.64
Thus, if the compounding period is increased to monthly, the amount due on the loan would be $12033.64.

What are the 4 method of quadratic equation?
The four methods to solve quadratic equations are factorising, quadratic formula, graphing and completing the square.
Factorising is nothing but the method of equating the given equation to zero.
Quadratic formula method is by placing the coefficients of the given quadratic equation into the formula and obtaining the solutions.
Completing the square method is when a quadratic equation has a square term. We would once more have a linear equation if we could place two square terms on either side of the quality sign.
We can find the solution of a quadratic equation using a graph. Rearrange the equation so that one side corresponds to the graphed function. Plot this function and write y = the other side of the equation. To obtain the answers, draw vertical lines from the intersection spots down to the x-axis.

Jerry tarted doing it-up every day. The firt day he did 15 it-up. Every day after that he did 2 more it-up than he had done the previou day. Today Jerry did 33 it-up. Write an equation that could be olved to find the number of day Jerry ha been doing it-up, not counting the firt day
Jerry has been doing it-up for number of 10 days , not counting the first day.
n + 14 = 33
n = 19 days
We know that Jerry did 15 it-up on the first day and 33 it-up today. Therefore, we can subtract 15 from 33 to get the total number of it-up that Jerry did over the past few days.
33 - 15 = 18e
We know that Jerry did 2 more it-up each day, so we can divide 18 by 2 to get the number of days.
18 / 2 = 9
Finally, we need to add 1 to the result to account for the first day.
9 + 1 = 10 days
Jerry has been doing it-up for 10 days, not counting the first day.

Create the graphical summary.
Write a sentence that describes the data. Write a sentence that describes the data. Choose the correct answer below.
O The distribution is bell shaped.
O The distribution is skewed right.
O The distribution is uniform.
O The distribution is skewed left.
The distribution of the data is skewed right, which means that the data is not evenly distributed across the range of values.
To calculate the skewness, we can use the formula Skewness = (Mean - Mode) / Standard Deviation. In this case, the mean is 599.2 seconds, the mode is 590 seconds, and the standard deviation is 110.88 seconds. Plugging these values into the formula, we get Skewness = (599.2 - 590) / 110.88 = 0.8094. This indicates that the data is skewed right, as the skewness is greater than 0. A right-skewed distribution typically occurs when the majority of data points are closer to the minimum value, while there are fewer data points near the maximum value. This can be seen in the graphical summary, where the majority of the data points are clustered around the lower end of the range and the tail extends to the right.

Octagon Towers is an octagon-shaped condominium building in Miami, Florida. Assuming the base of Octagon Towers is a regular octagon, find the measure of each interior angle of the base of Octagon Towers.
Each interior angle measures ?
Answer: The measure of each interior angle of a regular octagon can be found using the formula:
(n-2) x 180 / n
Where n is the number of sides in the polygon.
For Octagon, n=8
So we can substitute 8 for n in the formula:
(8-2) x 180 / 8 = 6 x 180 / 8
Therefore, each interior angle of the base of Octagon Towers measures 135 degrees.

What is horizontal line test answer?
The horizontal line test is a method used in mathematics to determine if a given function is one-to-one. A function is one-to-one if for every unique x-value, there is a unique y-value.
The horizontal line test is used to determine if a function is one-to-one by drawing a horizontal line through the graph of the function and seeing if the line intersects the graph at most once.
The horizontal line test is based on the idea that if a horizontal line intersects the graph of a function more than once, then there must be at least one pair of x-values that correspond to the same y-value.
This means that the function is not one-to-one and therefore, not invertible. A function that is not invertible is not a function in strict mathematical sense.
It's important to note that the horizontal line test can only be applied to functions that are defined on a closed interval or on all real numbers.
Also, It is only a sufficient condition, meaning that a function that passes the horizontal line test is one-to-one, but not all one-to-one function pass the horizontal line test.
In conclusion, the horizontal line test is a method used to determine if a given function is one-to-one by drawing a horizontal line through the graph of the function and seeing if the line intersects the graph at most once.
If it does, the function is one-to-one, if not, the function is not one-to-one and therefore not invertible. The test is only sufficient and should be used with caution.

The perimeter of a rectangle is 172 feet. Find the length and width if the length is an integer and the width is 2 times the next consecutive integer.
The length of the rectangle is 28 feet, and the width is 58 feet.
How to find the length and width of the rectangle?We know that for a rectangle of length L and width W, the perimeter can be written as:
P = 2*(L + W)
Here we know that the perimeter is 172 ft, then we can write:
172 ft = 2*(L + W)
And we know that the length is an integer:
L = x
And the width is two times the next integer:
W = 2*(x + 1)
Then we can replace these two in the perimeter equation so we get:
172 = 2*(x + 2*(x + 1))
172 = 2*(x + 2x + 2)
172 = 6x + 4
172 - 4 = 6x
168 = 6x
168/6 = x
28 = x
So we have:
Length = x = 28 ft
Width = 2*(x + 1) = 2*(29) ft = 58ft

How to represent a situation with an equation?A roast beef sandwich costs $6.75. A customer buys multiple roast beef sandwiches. Let x represent the number of roast beef sandwiches.
Then we will find the how many sandwiches the customer buys when the amount Used for Payment is $50 and change received is $16.25.

where
x = the number of roast beef sandwichesTherefore, let's find the number of sandwich bought using the equation.
16.25 = 50 - 6.75x
16.25 - 50 = - 6.75x
-33.75 = -6.75x

A local bank is advertising that you can double your money in eight years if you invest with them. Suppose you have $1,000 to invest. What interest rate is the bank offering? Show both compound and simple.
a) The compound interest rate is 75%
b) The simple interest rate is 12.5%
What is the interest?
We know that the interest is the money that accrues to an investment that have been made. We know that we can be able to determine the simple interest by the use of the formula.
A = P(1 + r/n)^nt
A = amount
P = principal
r = rate
n = Number of times compounded
Then we have;
2(1000) = 1000(1 + r)^8
Where n = 1
2 = (1 + r)^8
0.693 = 8 ln(1 + r)
e^0.693/8= (1 + r)
r = 1 - e^0.693/8
r = 0.75 or 75%
For the simple interest rate;
I = PRT/100
I = A - P
I = 2000 - 1000 = 1000
1000 = 1000 * R * 8/100

At noon, a tank contains 5 in of water. After several hours, it contained 3 in of water. What is the percent decrease of water in the tank?
Answer: To calculate the percent decrease of water in the tank, we can use the following formula:
Percent decrease = (Initial value - Final value) / Initial value x 100%
In this case, the initial value of water in the tank is 5 inches and the final value is 3 inches. So, the percent decrease is:
(5 - 3) / 5 x 100% = 2 / 5 x 100% = 40%
So, the percent decrease of water in the tank is 40%.
