A certificate of deposit often charges a penalty for withdrawing funds before the maturity date. If the penalty involves two months of interest, what would be tbe amount for early withdrawal on a CD paying 7 percent and valued at $18,000? (Do not round intermediate calculations. Round your answer to 2 decimal places.)
Penalty time = 2 months of interest = 2 x (7/100 x 18,000) = $2520.00
This serves as a deterrent to encourage individuals to leave their money in the CD until the maturity date.
Penalty = 2 months of interest = 2 x (Interest rate/100 x Value of CD)
= 2 x (7/100 x 18,000)
= $2520.00
A certificate of deposit (CD) is a financial product offered by banks and credit unions that allows an individual to deposit a certain amount of money for a fixed period of time, usually a few months to a few years. Most CDs will pay a higher rate of interest than a traditional savings account, but they come with certain restrictions. One of these restrictions is that if you withdraw funds from the CD before it reaches maturity, you will be charged a penalty time. This penalty usually involves two months of interest. Therefore, the amount of the penalty for early withdrawal on a CD with a value of $18,000 and paying 7 percent interest would be 2 x (7/100 x 18,000) = $2520.00. This serves as a deterrent to encourage individuals to leave their money in the CD until the maturity date.

An executive invests $23,000, some at 7% and the rest at 6% annual interest. If he receives an annual return of $1,480, how much is invested at each rate?
Answer:
The investments were made as follows:
$10,000 at 7% interest
$13,000 at 6% interest
Step-by-step explanation:
First remember that percentages are to be divided by 100 before any calculations can be made
So 7% = 0.07
8% = 0.08
Let x be the amount invested at 7% and y be the amount invested at 8%
We have:
x + y = 23000 (total amount is $23000)
Return on x = 0.07x
Return on y = 0.06y
Total return is
0.07x + 0.06y = 1480
The two equations are
x + y = 23000 [1]
0.07x + 0.06y = 1480 [2]
To solve for x and y,
multiply [1] x 0.07
=> 0.07x + 0.07y = 0.07(23000)
=> 0.07x + 0.07y = 1610 [3]
Since the coefficients of x are the same we can subtract [2] from [3] to eliminate the x term and solve for y
[3] - [2]:
(0.07x + 0.07y ) - (0.07x + 0.06y) = 1610 - 1480
0.07x + 0.07y - 0.07x - 0.06y = 130
Collecting like terms
0.07x-0.07x +0.07y - 0.06y = 130
0.01y = 130
y = 130/0.01 = 13000
x = 23000 - 13000 = 10000
Therefore the investments were made as follows:
$10,000 at 7% interest
$13,000 at 6% interest
the length of the hypotenuse h is a right angled triangle is given by the formula h=√9²+b² where a and b are the lengths of the other two sides of the triangle. make a the subject of the formula?
Answer: The formula you provided is the Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse (h) is equal to the sum of the squares of the lengths of the other two sides (a and b). The formula can be written as:
h = √(a^2 + b^2)
To make a the subject of the formula, we can start by squaring both sides of the equation:
h^2 = a^2 + b^2
We can then subtract b^2 from both sides:
h^2 - b^2 = a^2
Now we can take the square root of both sides:
√(h^2 - b^2) = √a^2
a = √(h^2 - b^2)
So, a is the square root of the difference between the square of the hypotenuse and the square of the other side.

Stefan sells Jin a bicycle for $116 and a helmet for $16. The total cost for Jin is 120% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally? How much money did he make by selling the bicycle and helmet to Jin?
Answer:
see below
Step-by-step explanation:
116+16=132 =120% * x
x=110
profit =132-110 =22
He made $12 by selling the bicycle helmet to Jin!
Step-by-step explanation:Let x be the original cost of the bicycle.
The cost of the helmet is $16, so the original cost of the bicycle and helmet is x + $16 algebraically.
Jin pays a total of $116 + $16 = $132 for the bicycle and helmet, which is 120% of what Stefan spent originally, so x + $16 = 1.2 * (x + $16)
Expanding the right-hand side gives x + $16 = 1.2x + 1.2 * $16.
Solving for x, we find that x = $104.
So, Stefan originally spent $104 for the bicycle and $16 for the helmet, for a total of $104 + $16 = $120.
Stefan sells the bicycle and helmet to Jin for $116 + $16 = $132, so he makes a profit of $132 - $120 = $12.

Dr. Leona Williams, a well-known plastic surgeon, has a reputation for being one of the best surgeons for reconstructive nose surgery. Dr. Williams enjoys a rather substantial degree of market power in this market. She has estimated demand for her work to be: Q = 480 – 0.2P where Q is the number of nose operations performed monthly and P is the price of a nose operation. What is the inverse demand function for Dr. Williams’ services? What is the marginal revenue function?
The average variable cost function for reconstructive nose surgery is estimated to be:
AVC = 2Q2 – 15Q + 400
where AVC is the average variable cost (measured in dollars), and Q is the number of operations per month. The doctor’s fixed cost per month is $8,000. If the doctor wishes to maximize her profit, how many nose operations should she perform each month?
What price should Dr. Williams charge to perform a nose operation?
How much profit does she earn each month?
The inverse demand function is P = 2400 + 5Q
The Marginal Revenue function is MR = 5QThe number of nose operations is 15The price per month is $2475Dr. Williams earns $19750 in profit each monthHow to determine the inverse demand functionGiven that
Q = 480 - 0.2P
We simply make P the subject of the formula
So, we have
0.2P = 480 - Q
Divide by 0.2
P = 2400 + 5Q
The marginal revenue functionTo find the marginal revenue function, we can use the inverse demand function P = 2400 + 5Q, and take the derivative of this function with respect to Q.
The derivative of P with respect to Q is dP/dQ = 5. This represents the change in price for a one unit change in the quantity of operations performed.
So the Marginal Revenue function is MR = dP/dQ * Q = 5Q
The number of nose operationsTo maximize profit, the doctor should equate marginal revenue to marginal cost, which is
MC = dAVC/dQ
So, we have
MC = d(2Q² - 15Q + 400)/dQ
Evaluate
MC = 4Q - 15.
So, we have
5Q = 4Q - 15
Q = -15
Take the absolute value
Q = 15
So, the number of operations is 15
The price for each operationWe have
P = 2400 + 5Q
This gives
P = 2400 + 5 * 15
Evaluate
P = 2475
The monthly profitTo find the profit, we need to subtract the total cost from the total revenue.
The total revenue is found by multiplying the price by the quantity of operations performed: TR = P * Q = 2475 * 15 = 37125
The total variable cost is found by multiplying the average variable cost by the quantity of operations performed: TVC = AVC * Q = (2Q^2 - 15Q + 400) * Q = 2Q^3 - 15Q^2 + 400Q
The total fixed cost is the fixed cost that doesn't change regardless of the level of output : TFC = $8000
The total cost is the sum of the total variable cost and total fixed cost: TC = TVC + TFC = 2Q^3 - 15Q^2 + 400Q + $8000
The profit is the difference between total revenue and total cost:
π = TR - TC = 37125 - (2Q^3 - 15Q^2 + 400Q + $8000)
When Q = 15,
profit is π = 37125 - (2(15)^3 - 15(15)^2 + 400(15) + $8000)

d) Maximum = x = 8 in., V = x^3 = 512 in^3
The volume V of a cardboard box with a square base is a function of the length x of each edge of the base. To calculate the volume of the box, we can use the formula V = x^3. This means that for any given base length, we can find the volume by cubing the length. The domain of V is the set of all possible values of x, which must be positive. This means that the domain of V is [0, ∞). We can also graph the function V = x^3. The graph looks like a parabola that opens up, with the vertex at the origin. We can then find the maximum of the function, which will be when x = 8 in. At this value, the volume of the box will be V = 512 in^3

The slope of the line perpendicular to the line whose equation is 15x - 12y = 216 is m{p} = -0.8.
What is the general equation of a straight line?
straight line equation: The general equation of a straight line is -
y = mx + c.
where,
{m}: slope of the line.
{c} : y-intercept
To find the slope of a line perpendicular to the line whose equation is 15x - 12y = 216, we need to find the negative reciprocal of the original line's slope.
To find the original line's slope, we can use the equation of the line in slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.
To convert the equation of the line from standard form to slope-intercept form, we can add 12y to both sides to get 12y = -15x + 216.
Then divide both sides by 12 to get y = -(15/12)x + 18.
So the slope of the original line is -(15/12).
The slope of a line perpendicular to the original line is the negative reciprocal of the original line's slope.
So the slope of the line perpendicular to 15x - 12y = 216 is -12/15 or -0.8
The slope of the line perpendicular to the given line is -
m = -12/15 = -0.8
Therefore, the slope of the line perpendicular to the line whose equation is 15x - 12y = 216 is m{p} = -0.8.

The volume of water which the tank holds when it is full is 136830 cm³.
What is volume?The amount of space a three-dimensional solid shape takes up is referred to as its volume. Though difficult to visualise in any shape, it can be compared to others. In comparison to an eraser placed inside of it, a compass box has a larger volume. The area of any two-dimensional shape can be calculated by splitting it into equal squares. When calculating the volume of solid shapes, equal cubical units will also be divided.
If the both have diameter of 46 cm then the height of hemisphere is
46/2 = 23 cm = radius
Height of the cylinder = 90 - 23
= 67
Volume of hemisphere + Volume of cylinder = volume of water
volume of water = (2/3)πr³ + πr²h
volume of water = (2/3)π(23)³ + π(23)²×67
= 136830 cm³
= 136.83 l
Thus, the volume of water which the tank holds when it is full is 136830 cm³.

What is explicit formula?An explicit formula for f(n), the number of members the creators have a goal of getting n weeks after the website is made available, can be determined by using the information provided that the number of members is tripled every week.
So, we can start with the initial number of members (10) and multiply it by 3 for each week.
Therefore, the explicit formula for f(n) is:
f(n) = 10 * [tex]3^{(n - 1)}[/tex]
A recursive formula for f(n) can be determined by using the information that the number of members is tripled every week, and the initial number of members is 10.
So, we can start with the initial number of members (f(1)=10) and use the previous value of f(n-1) to calculate the current value of f(n).
Therefore, the recursive formula for f(n) is:
f(n) = 3f(n-1) + 10
for n>1
f(1)=10
In this way, we can calculate the number of members for any week using the explicit formula or the recursive formula.
