which of the following is not true of the u.s. rule?multiple choicecan involve more than one payment before maturity datecan use 365 days in its calculationsallows borrower to receive proper interest creditscalculate interest on principal from date of loan to date of first payment
None of the above is the correct answer. There is no answer in the given choices.
The U.S. Rule produces no compounding of interest in that any unpaid accrued interest is accumulated separately and is not added to the principal.
At maturity, using the U.S. rule, the interest calculated from the last partial payment is subtracted from the beginning balance and added to the adjusted balance.
Under U.S. Rule, unpaid accrued interest is accumulated separately and is not added to the principal. In addition, interest is not calculated until payment is made.
It also allows the borrower to receive proper interest credits. This rule defines that any partial loan payment first covers any interest that has built up, and the remainder of the partial payment will decrease the loan principal.

The optimal solution to the LP problem is (x,y) = (8,10). The objective function is minimized at this point, with a minimum value of 18.
We can solve this LP problem by using the graphical method.
First, we plot the constraints:
x + 3y <= 28 --> y <= -(1/3)x + 28/3
5x + y <= 28 --> y <= -5x + 28
x >= 0
y >= 0
Next, we find the feasible region formed by the intersection of these constraints. This region is a bounded polygon and is shown in blue in the figure below.
Finally, we find the point in the feasible region that minimizes the objective function c = x + 2y. We do this by plotting the objective function as a straight line with slope equal to 2 and y-intercept equal to 0. The line should pass through the feasible region and intersect it at the point with the minimum value of c.
From the figure, we can see that the line intersects the feasible region at the point (8, 10), which is the minimum value of c = x + 2y, with a minimum value of 18.
Therefore, the optimal solution to the LP problem is (x,y) = (8,10).

Add -12+7 = what is the answer ?
Answer:
-12 + 7 = -5
Step-by-step explanation:
An example of this equation could be if you owe someone $12 and then receive $7 from them, your debt to them would be reduced to $5. Another example could be if you have 12 apples and someone gives you 7 apples, you would have a total of 19 apples.
leonard mccoy is a manager at a coffee shop, and he has to decide how many workers to hire. one worker can make 30 drinks that sell for $2.50 on average in one hour. a second worker can make another 25 drinks in one hour.
McCoy should hire two workers if their total profit is greater than the total profit of one worker.
To calculate how many workers McCoy should hire to make the most profit, he must first calculate the total number of drinks that can be made in one hour. One worker can make 30 drinks in an hour, and a second worker can make 25 drinks in an hour. This means that with two workers, 55 drinks can be made in one hour.
The next step is to calculate the total profit that can be made in one hour. This can be done using the formula Profit = Price x Quantity. Since the drinks sell for $2.50 on average and the total number of drinks made in one hour is 55, the total profit from one hour of work is $137.50.
This means that hiring two workers can make McCoy $137.50 in profit in one hour. To decide if this is the best option, McCoy should compare the total profit of two workers to the total profit of one worker. If the total profit of two workers is greater than the total profit of one worker, then McCoy should hire two workers. If the total profit of one worker is greater than the total profit of two workers, then McCoy should hire one worker.
McCoy should hire two workers if their total profit is greater than the total profit of one worker.

Verify that the indicated function is an explicit solution of thegiven differential equation. Assume an appropriate intervalI of the definition for each solution.
dy/dt + 20y = 24; y = 6/5 - (6/5)e-20t
To verify that the given function is an explicit solution of the given differential equation, we can plug it into the differential equation and see if it satisfies the equation.
Plugging in the given function, we get: dy/dt + 20y = 24; (6/5)e-20t - 6/5 = 24. Simplifying, we get 0 = 0, which is true. This means that the given function is an explicit solution of the differential equation, and it is valid on any interval I.
To find a function solution to a differential equation, you must first identify the type of equation you are dealing with. If it is a linear equation, you can use the method of integrating factors or the method of undetermined coefficients, depending on the equation.
If it is a nonlinear equation, you can use the method of separation of variables, the method of substitution, or the method of series solutions. Once you have identified the equation, you can use the appropriate method to find the solution.

The probability that an adult has a great deal of confidence in both scientists and religious leaders is equal to A x B = (43/100)(17/100) = 0.0721, or p = 7.21%.
I choose option 1. The percent of surveyed U.S. adults who had a great deal of confidence in both scientists and religious leaders is equal to p%.
To calculate p, we use the multiplication rule, which states that the probability of two independent events occurring together is equal to the product of their individual probabilities.
In this case, let A be the probability that an adult has a great deal of confidence in scientists, and let B be the probability that an adult has a great deal of confidence in religious leaders.
A = 43/100
B = 17/100
Therefore, the probability that an adult has a great deal of confidence in both scientists and religious leaders is equal to A x B = (43/100)(17/100) = 0.0721, or p = 7.21%.

No, because (-1, -5) is above the line.
How to find if the ordered pair is a solutionThe inequality y < -3/4x - 1 represents a line on a coordinate plane.
The inequality symbol "<" means that the values of y that satisfy the inequality are those that are strictly less than the value of the right-hand side of the equation.
So, for any given x-value, all y-values that are less than the corresponding y-value on the line satisfy the inequality.
In this case, when x = -1, the corresponding y-value on the line is -3/4 * -1 - 1 = 1/4.

a.Calculate the cross price elasticity of demand for
the commodity and interpret your results.
b. If the price of the commodity rather decreased

elasticity of demand and interpret your results.
1. The price elasticity of demand for pen is 0.5
2. The cross price elasticity of demand for the commodity is 0.667
3. The cross price elasticity of demand is 0.8
What is Elasticity of Demand?The degree to which demand reacts to a change in an economic component is known as elasticity of demand. The most prevalent economic component considered when calculating elasticity is price. Income level and the accessibility of substitutes are further considerations. Elasticity gauges how demand changes in response to shifting economic conditions.
Given:
1. The demand for pen decreased from 100 to 70.
So, the percentage change in quantity
= (100 -70) / 100 = 0.3 = 30%
percentage change in the price
= (5 - 2) / 5
= 3/5
= 60 %
So, Cross price elasticity = 30% / 60% = 0.5
2. The quantity demanded of a commodity decreased from 50kg to 30kg.
So, the percentage change in quantity
= (50- 30)/50
= 40%
and, percentage change in price
= (8- 5)/5
= 60%
Then, cross price elasticity
= 40% / 60%
= 0.6667
Now, If the price of the commodity rather decreased from Gh¢5.00 to Gh¢2.50
So, the percentage change in price
= (5 - 2.5)/5
= 50%
Then, cross price elasticity
= 40% / 50%

Then the number of degrees in the larger angle = 3x
Given that the two angles are in the ratio of 2 to 3
2x = 3x
x = 60
Therefore, the number of degrees in the smaller angle is 60 degrees.
The two supplementary angles are supplementary angles because the sum of their angles is 180 degrees. This means that if we denote the number of degrees in the smaller angle as x, then the number of degrees in the larger angle must be 180-x. We know that their ratio is 2 to 3, which can be written as 2x = 3(180-x). Solving this equation gives us x = 60, so the number of degrees in the smaller angle is 60.
