What is Discount coupon?A discount coupon is defined as a certificate that entitles the customer to avail of a reduction in the invoice price if the terms mentioned on it are met. It is a technique applied by the sellers to expand sales.
Given that, Clarks Inc., a shoe retailer, sells boots in different styles. In early November, the company starts selling “SunBoots” to customers for $70 per pair. When a customer purchases a pair of SunBoots, Clarks also gives the customer a 30% discount coupon for any additional future purchases made in the next 30 days. Customers can’t obtain the discount coupon otherwise. Clarks anticipates that approximately 20% of customers will utilize the coupon, and that on average those customers will purchase additional goods that normally sell for $100.
a) Two performance obligations are associated with contract. The first one is related to the sun boots, and the other one is associated with discount coupon provided. The discount coupon would be considered a separate obligation because it gives a certain right to the customers that they would not have received if the sale was not made to them.

The indefinite integral is - 1 / [5(6 + [tex]x^{5}[/tex])] + C.
An integral is considered to be indefinite if it has no upper or lower bounds. In mathematics, the most generic antiderivative of f(x) is known as an indefinite integral and expressed by the expression f(x) dx = F(x) + C. Without upper and lower bounds on the integrand, indefinite integrals are stated using the notation f(x), which represents the function as an antiderivative of F. Consequently, "f(x) dx=F" (x). As we observed in the same example with antiderivatives, the integral, x3 dx=14x4+C, is one example.
The area under the f(x) curve from x=a to x=b is represented by the definite integral of f(x), which is a NUMBER. Integral indefinite. An indefinite integral of a function f(x), also known as an antiderivative, is denoted by and its derivative is denoted by f. (x). The indefinite integral is not the only solution because the derivative of a constant is zero. Integration is the action of locating an indefinite integral.

Please can someone explain this question to me step-by step, i have a exam this Wednesday so pleasee help me!! Help is greatly greatly appreciated ^^
Thankyou!!
Answer:
AB = 45.688 metres
Step-by-step explanation:
* i used a scientific calculator for my working. i am not sure if calculators are permitted for your exam on Wednesday *
⭐AB = AD + DB
⭐AB = 16.5 + DB
Thus, we need to find DB in order to solve for AB.
First, I utilized the triangle sum theorem to find ∠BDC:
[tex]< BDC + < DCB + < B = 180\\ < BDC + 59 + 90 = 180\\ < BDC + 149 = 180\\ < BDC = 31[/tex]
Then, I utilized the linear pair sum to find ∠ADC:
[tex]< ADC + < BDC = 180\\ < ADC + 31 = 180\\ < ADC = 149[/tex]
Next, I utilized the triangle sum theorem to find ∠DAC:
[tex]< DAC + < ADC + < ACD = 180[/tex]
[tex]< DAC + 149 + 10 = 180[/tex]
[tex]< DAC + 159 = 180[/tex]
[tex]< DAC = 21[/tex]
After, I utilized the law of sines to find DC:
[tex]\frac{sin10}{16.5} = \frac{sin21}{DC}[/tex]
[tex]DCsin10 = 16.5sin21[/tex]
[tex]DC = \frac{16.5sin21}{sin10}[/tex]
[tex]DC = 34.052[/tex]
Then, I utilized the sine function to find DB for ΔBDC:
[tex]sin(59) = \frac{DB}{34.052}[/tex]
[tex]34.052sin(59) = DB[/tex]
[tex]29.188 = DB[/tex]
Finally, I substituted DB into our original equation for AB:
[tex]AB = AD + DB[/tex]
[tex]AB = 16.5 + 29.188[/tex]
[tex]AB = 45.688 metres[/tex]
Good luck on your exam on Wednesday! :-)
The height of the pole will be equal to 45 meters.
Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions. There are numerous distinctive trigonometric identities that relate to a triangle's side length and angle.
Given that the angle BCD is 59 and the angle BCA is 69. The height will be calculated as,
tan(59) = BD / BC
BC = BD / tan(59)
BC = 0.6BD
tan(69) = AB / BC
tan(69) = ( 16.5 + BD ) / BC
BC = 0.38( 16.5 + BD )
Equate the values of BC,
0.6BD = 0.38 ( 16.5 + BD )
0.6BD = 6.27 + 0.38BD
0.22BD =6.27
BD = 28.5 meters
The height of the pole is,
AB = AD + DB
AB = 16.5 + 28.5
AB = 45 meters

The number of bacteria in a sample is increasing according to an exponential model. After four hours, the sample contained 400 bacteria. After twelve hours, the sample contained 1,600 bacteria. Write an exponential growth model for the number of bacteria in the sample after x hours.
The solution is Option A.
The exponential growth model for the number of bacteria in the sample after x hours is [tex]P ( x ) = 200 e ^{(\frac{ln 4}{8})x }[/tex]
What is exponential growth factor?
The exponential growth or decay formula is given by
x ( t ) = x₀ × ( 1 + r )ⁿ
x ( t ) is the value at time t
x₀ is the initial value at time t = 0.
r is the growth rate when r>0 or decay rate when r<0, in percent
t is the time in discrete intervals and selected time units
Given data ,
Let the equation for the number of bacteria in the sample after x hours = P

A store charges a rate per minute plus a flat fee to rent cleaning supplies. A 30 minute rental $110.50. A 40 minute rental costs $145. How much for a 25 minute rental
The cost of a 25-minute rental will be $92.00.
To find the amount a 25-minute rental would cost, we need to first determine the rate per minute and the flat fee. We can do this by setting up the following system of equations:
30 minutes x rate + flat fee = $110.50
40 minutes x rate + flat fee = $145
To solve this system of equations, we can multiply the first equation by 2 and subtract the second equation from it to eliminate the rate:
(30 minutes x 2) x rate + flat fee x 2 = 2 x $110.50
80 minutes x rate + flat fee x 2 = 2 x $110.50
Subtracting the second equation from the first equation, we get:
flat fee x 2 - flat fee x 2 = 2 x $110.50 - 2 x $145
flat fee x 2 - flat fee x 2 = -$34.50
Since the left side of the equation is equal to zero, we can divide both sides by 2 to solve for the flat fee:
flat fee - flat fee = -$34.50 / 2
flat fee - flat fee = -$17.25
Since the left side of the equation is also equal to zero, the flat fee must be zero.
We can now use either of the original equations to solve for the rate per minute. Using the first equation, we get:
30 minutes x rate + flat fee = $110.50
30 minutes x rate = $110.50
rate = $3.68
We can now use this rate to find the cost of a 25-minute rental:
25 minutes x $3.68 + flat fee = $92.00 (Since the flat fee is zero)
Thus, a rental of 25 minutes costs $92.00.

The critical value is -2.70
What is a null hypothesis?
Two alternatives being the same is the null hypothesis. The underlying assumption is that the observed difference is just the result of chance. It is feasible to estimate the probability that the null hypothesis is correct using statistical testing.
Here, we have
The objective of this experiment is to compare two compounds, designed to reduce braking distance, used in tire manufacturing to prove if the braking distance of SUVs equipped with tires made with compound 1 is shorter than the braking distance of SUVs equipped with tires made with compound 2.
So you have 2 independent populations, SUV's equipped with tires made using compound 1 and SUVs equipped with tires made using compound 2.
Two samples of 66 braking tests are made and the braking distance was measured each time, the study variables are determined as:
X₁: Braking distance of an SUV equipped with tires made with compound one.
Its sample mean is X[bar]₁= 41 feet
And the Standard deviation S₁= 12.1 feet
X₂: Braking distance of an SUV equipped with tires made with compound two.
Its sample mean is X[bar]₂= 46 feet
And the Standard deviation S₂= 9.0 feet
We don't have any information on the distribution of the study variables, nor the sample data to test it, but since both sample sizes are large enough n₁ and n₂ ≥ 30 we can apply the central limit theorem and approximate the distribution of both variables sample means to normal.
The researcher's hypothesis, as mentioned before, is that the braking distance using compound one is less than the distance obtained using compound 2, symbolically: μ₁ < μ₂
The statistical hypotheses are:
H₀: μ₁ ≥ μ₂
H₁: μ₁ < μ₂
α: 0.05
The statistic to use to compare these two populations is a pooled Z test
Z= {(X[bar]₁-X[bar]₂) - (μ₁ - μ₂)}/√S₁²/n₁+S₂²/n₂ ≈ N(0;1)
Z = {(41-46)-0}/√146.41/66+81/66
Z = -5/1.85
Z = -2.70
The rejection region of this hypothesis test is one-tailed to the right, so you'll reject the null hypothesis to small values of the statistic. The critical value for this test is:
Z(α) = Z(0.05) = -1.645
Decision rule:
If Z(H₀) ≥ -1.645, then you do not reject the null hypothesis.
If Z(H₀) < -1.645, then you reject the null hypothesis.
Since the statistic value is greater than the critical value, the decision is to not reject the null hypothesis.
At a 5% significance level, you can conclude that the average braking distance of SUVs equipped with tires manufactured used compound 1 is greater than the average braking distance of SUVs equipped with tires manufactured used compound 2.
Hence, the critical value is -2.70.

What is factorization?Factoring an algebraic expression specifically means writing a given expression as the product of its factors. These factors may be numbers, variables, or algebraic expressions.
1, 2, 6, and 12 are all divisors of 12 because they divide 12 equally. This is an important algebraic operation, which is used to simplify expressions, simplify fractions, and solve equations. This is also called algebraic factorization.
Factorization of x² + 2x - 3
x² + 3x - x - 3
(x² + 3x) - (x + 3)
x(x + 3) - 1(x + 3)
(x + 3)(x - 1)
Factorization of x² + 3x - 4
x² + 4x - x - 4
(x² + 4x) - (x + 4)
x(x + 4) - 1(x + 4)
(x + 4)(x - 1)
Factorization of x² - 2x - 3
x² - 3x + x - 3
(x² - 3x) + (x - 3)
x(x - 3) + 1(x - 3)
(x - 3)(x + 1)
Using identity, a² - b² = (a + b)(a - b)
x² - 9 = x² - 3²
x² - 3² = (x + 3)(x - 3)
Now, for the division:
(x² + 2x - 3)/(x² - 9) ÷ (x² + 3x - 4)/(x² - 2x - 3)
[(x + 3)(x - 1)/(x + 3)(x - 3)] ÷ [(x + 4)(x - 1)/(x - 3)(x + 1)]
By reciprocal of (x + 4)(x - 1)/(x - 3)(x + 1)
[(x + 3)(x - 1)/(x + 3)(x - 3)] × [(x - 3)(x + 1)/(x + 4)(x - 1)]
= (x + 1)/(x + 4)

Some values of f(x, y) are given below. Write out the terms of a Riemann Sum (using four squares) that gives an upper estimate of r 4 0 r 4 0 f dx dy.
To find a Riemann sum that gives an upper estimate of the double integral, we need to divide the region of integration into small subregions (in this case, squares) and take the maximum value of f(x, y) over each subregion.
The Riemann sum will then be the sum of the areas of the subregions times the maximum value of f(x, y) over each subregion.
For example, if we divide the region of integration into four squares, the Riemann sum would be given by:
Riemann sum = (area of first square) * (maximum value of f(x, y) in first
square) + (area of second square) * (maximum value of
f(x, y) in second square) + (area of third square) *
(maximum value of f(x, y) in third square) + (area of fourth
square) * (maximum value of f(x, y) in fourth square)
We can then fill in the specific values of the areas and maximum values of f(x, y) for each square based on the given values of f(x, y).

Martha has a $200 deductible and 20% co-payment on her health
insurance. Last year she had $6,500 in medical bills. What was
Martha's out-of-pocket expense?
Answer:
Step-by-step explanation:
To solve this problem, we need to calculate Martha's out-of-pocket expenses, and the total amount of money she had to pay for her medical bills.
First, we need to calculate the amount of money Martha had to pay toward her deductible. Since her deductible is $200, this is the amount she had to pay out of pocket.
Next, we need to calculate the amount of money Martha had to pay toward her co-payment. Since her co-payment is 20%, we can calculate this by multiplying her medical bills by the co-payment rate: $6,500 x 0.2 = $1,300.
To find Martha's total out-of-pocket expense, we can add the amount she paid towards her deductible ($200) and the amount she paid towards her co-payment ($1,300):
$200 + $1,300 = $1,500
Therefore, Martha's out-of-pocket expense was $1,500.
Martha's insurance required her to pay a $200 deductible and a 20% co-payment on the remaining balance of her medical bills. After paying the deductible, she pays 20% of the remaining $6,300 which is $1,260. So, Martha's total out-of-pocket expense was $1,460.
Explanation:Martha's health insurance plan includes a $200 deductible and a 20% co-payment. The deductible is the amount Martha has to pay before the insurance company starts to pay. In this case, Martha first pays a $200 deductible from her $6,500 medical bills, which leaves her with $6,300 to be covered by insurance and her co-payment. The 20% co-payment means Martha is responsible for paying 20% of the remaining $6,300. To calculate this, we multiply $6,300 by 0.20 (20%), which equals $1,260. Therefore, Martha's total out-of-pocket expense for her medical bills last year was the $200 deductible plus the $1,260 co-payment, equalling $1,460.

A total of $28000 is invested in 2 municipal bonds that pay 5.75% and 7.25% simple interest. The investor wants an annual interest income of $1790 from the investments. What amount should be invested in the 5.75% bond?
Answer:
$16,000
Step-by-step explanation:
Simple Interest Formula
I = Prt
where:
I = Interest accruedP = Principal amountr = Interest rate (in decimal form)t = Time (in years)Let investment 1 be the bond that pays 5.75% simple interest.
Let investment 2 be the bond that pays 7.25% simple interest.
Given:
P₁ + P₂ = $28,000r₁ = 5.75% = 0.0575r₂ = 7.25% = 0.0725t = 1 yearCreate two equations for the interest from both investments.
Interest from Investment 1
[tex]\implies \sf I_1=P_1 \cdot 0.0575 \cdot 1[/tex]
[tex]\implies \sf I_1=0.0575\:P_1[/tex]
Interest from Investment 2
[tex]\implies \sf I_2=P_2 \cdot 0.0725 \cdot 1[/tex]
[tex]\implies \sf I_2=(28000-P_1)0.0725[/tex]
[tex]\implies \sf I_2=2030-0.0725\:P_1[/tex]
Given that the sum of the interest from both investments is $1,790:
[tex]\implies \sf I_1+I_2=1790[/tex]
[tex]\implies \sf 0.0575\:P_1+2030-0.0725\:P_1=1790[/tex]
[tex]\implies \sf -0.015\:P_1=-240[/tex]
[tex]\implies \sf P_1=16000[/tex]
Therefore, $16,000 should be invested in the 5.75% bond.
Check:
[tex]\implies \sf I_1=16000 \cdot 0.0575 \cdot 1 = 920[/tex]
[tex]\implies \sf I_2=12000 \cdot 0.0725 \cdot 1 = 870[/tex]
[tex]\implies \sf I_1+I_2=920+870=1790[/tex]
