Answers
The given expressions, when A=1, B=0, and C=1, X evaluates to 1.001; when A=B=C=1, X evaluates to 1.111; and when A=B=C=0, X evaluates to 0.000. These evaluations are based on the given values of A, B, and C, and the notation ¯¯¯¯¯¯BC represents the complement of BC.
To evaluate the expression X = A.¯¯¯¯¯¯BC, we substitute the given values of A, B, and C into the expression.
(a) For A = 1, B = 0, and C = 1:
X = 1.¯¯¯¯¯¯01
To find the complement of BC, we replace B = 0 and C = 1 with their complements:
X = 1.¯¯¯¯¯¯01 = 1.¯¯¯¯¯¯00 = 1.001
(b) For A = B = C = 1:
X = 1.¯¯¯¯¯¯11
Similarly, we find the complement of BC by replacing B = 1 and C = 1 with their complements:
X = 1.¯¯¯¯¯¯11 = 1.¯¯¯¯¯¯00 = 1.111
(c) For A = B = C = 0:
X = 0.¯¯¯¯¯¯00
Again, we find the complement of BC by replacing B = 0 and C = 0 with their complements:
X = 0.¯¯¯¯¯¯00 = 0.¯¯¯¯¯¯11 = 0.000
In conclusion, when A = 1, B = 0, and C = 1, X evaluates to 1.001. When A = B = C = 1, X evaluates to 1.111. And when A = B = C = 0, X evaluates to 0.000. The evaluation of X is based on substituting the given values into the expression A.¯¯¯¯¯¯BC and finding the complement of BC in each case.

Tekan-Tekan Sdn. Bhd. has order for 200 Model AS-120 calculator for delivery on day 200. The calculator consists of three parts. Components 2 and 3 form subassembly 1 . Sub-assembly 1 and component 4 form the final assembly. Following are the work centers and times of each operation. Table Q3(a) shows routine file of the operation. Assuming: - Only one machine is assigned to each operation - The factory works on 8-hour shift, 5 days a week - All parts move in one lot of 200. (a) Illustrate the backward schedule based on the information given above. (12 marks) (b) Identify when component 3 must be started to meet the delivery date. (2 marks)
Answers
Component 3 must be started on day 197 to meet the delivery date of day 200.
To illustrate the backward schedule, we need to start from the delivery date (day 200) and work our way backward, taking into account the lead times and dependencies of each operation.
(a) Backward schedule:
Operation | Work Center | Time (hours) | Start Day
--------------------------------------------------------
Final Assembly | Work Center 1 | 1 | 200
Sub-assembly 1 | Work Center 2 | 2 | 199
Component 4 | Work Center 3 | 3 | 197
Component 2 | Work Center 4 | 4 | 196
Component 3 | Work Center 5 | 3 | ????
(b) To identify when component 3 must be started to meet the delivery date, we need to consider its dependencies and lead times.
From the backward schedule, we see that component 3 is required for sub-assembly 1, which is scheduled to start on day 199. The time required for sub-assembly 1 is 2 hours, which means it should be completed by the end of day 199.
Since component 3 is needed for sub-assembly 1, we can conclude that component 3 must be started at least 2 hours before the start of sub-assembly 1. Therefore, component 3 should be started on day 199 - 2 = 197 to ensure it is completed and ready for sub-assembly 1.
Hence, component 3 must be started on day 197 to meet the delivery date of day 200.

Use the Inverse Function Theorem to find (-1)(-8) given that f(x)=--&x-8. Note that r(0) = -8. (Do not include (¹)(-8)= in your answer.)
Answers
The inverse function theorem The Inverse Function Theorem is used to describe the derivative of the inverse function. The theorem also deals with continuity and differentiability of the inverse function.
Let's solve the given problem using the Inverse Function Theorem. To find (-1)(-8) given that f(x) = −√x − 8, we must first determine the inverse of f(x).Finding the inverse of the function First, let's switch x and y:
y = −√x − 8x
= −√y − 8Let's now solve for y
(-8 + x)² = y
Simplifying gives us:
y = x² − 16x + 64
To summarize, the inverse function is:f⁻¹(x) = x² − 16x + 64Finding the derivative of the inverse function
Now we need to find the derivative of the inverse function.
f⁻¹(x) = x² − 16x + 64f(x) = −√x − 8
Therefore:
f'(x) = −1/2(1/√x − 8)⁻² ∙

She was surprised to discover that she spent $150 on clothing and accessories. If Lakshmi decided to cut her monthly clothing and accessories expenditure in half, how much could she save in a year?
Answers
Using proportions, it is found that she would save $900 in a year.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
She spends $150 a month on clothing and accessories, hence, if she saves half of that, the amount saved in a month is:
0.5 x 150 = $75.
In a year, this amount will add up to:
75 x 12 = $900.

All of the statements are false except statement d. Counter-examples are given for each false statement each and explained below.
How to Write a Counter-example?a) The statement is incorrect because there may exist elements in set B that are not included in the union of sets A and B.
Counter-example: if we take A as {1} and B as {2}, we can see that B is not part of the union of A and B, denoted as A ∪ B.
(b) The statement is incorrect because the union of sets A and B can include elements that are not in set A.
Counterexample: Let A = {1} and B = {2}. Then (A ∪ B) = {1, 2}, and {1, 2} is not a subset of A since it contains an element (2) that is not in A.
(c) The statement is false because removing set B from the union of sets A and B may result in elements that are not present in set A.
Counterexample: Let A = {1} and B = {2}. Then (A ∪ B) - B = {1} - {2} = {1}, which is not equal to A.
(d) The statement is true because removing the set A from the set B minus A will result in set A itself.
(e) The statement is false because there can be cases where sets A, B, and C have overlapping elements, indicating that A is not disjoint from C.
Counterexample: Let A = {1}, B = {2}, and C = {1, 2}. Then A + B = {1, 2} and B + C = {1, 2}, but A ∩ C = {1} is not an empty set, so A and C are not disjoint.

Step-by-step explanation:
our equation is: (16x^2 - 9y^2)
With this equation, we must plug it into the formula: (a + b)(a - b) = a^2 - b^2
so,
a^2 = 16x^2
b^2 = 9y^2
then,
a = sqrt(16x^2) = 4x
b = sqrt(9y^2) = 3y
(these are the correct variables because 3*3 = 9, and 4*4 = 16)
now, we plug this information back into the formula again;
(a + b)(a - b) = (4x + 3y)(4x - 3y)
therefore, (4x + 3y)(4x - 3y) is the answer!

Answer:
After thirty days with the mentioned use the cost of the device is R$ 507,00.
Step-by-step explanation:
We first need to calculate its total power consumption over the 30 days. Since its turned on four times a day for 2 h and 36 min each, we need to multiply this time by 4 to have the time it's turned on in a day and multiply that by 30 to calculate its total power consumption. Although, we need to convert the time from hours and minutes to only hours, to do that we divide the minutes part by 60 and sum it on the hour part. All of this is done below:
\(t = 2 + \frac{36}{60} = 2.6 \text{ h}\)
\(\text{dayly time} = 4*t = 4*2.6 = 10.4 \text{ h}\)
\(\text{monthly time} = 30*\text{dayly time} = 30*10.4 = 312\text{ h}\)
\(\text{total power consumption} = \text{monthly time}*6500 = 312*6500\\\text{total power consumption} = 2028000 \text{ W} = 2028 \text{ kW}\)
\(\text{total cost} = \text{total power consumption}*0.25\\\text{total cost} = 2028*0.25\\\text{total cost} = 507\)
After thirty days with the mentioned use the cost of the device is R$ 507,00.

(b) what is the probability that the smallest drawn number is equal to k for k = 1,...,10?
Answers
To decide the opportunity that the smallest drawn wide variety is identical to k for k = 1,...,10, we need to consider the whole wide variety of viable consequences and the favorable effects for each case.
Assuming that you are referring to drawing numbers without alternative from a hard and fast of numbers, along with drawing numbers from a deck of playing cards or deciding on balls from an urn, the opportunity relies upon the unique scenario and the entire variety of factors inside the set.
For instance, if we're drawing three numbers from a hard and fast of 10 awesome numbers without replacement, we are able to examine every case:
The probability that the smallest drawn variety is 1:
In this example, the smallest quantity needs to be 1, and we should pick out 2 additional numbers from the ultimate nine numbers. The possibility is calculated as:
P(smallest = 1) = (1/10) * (9/9) * (8/8) = 1/10.
The probability that the smallest drawn quantity is 2:
In this example, the smallest range needs to be 2, and we need to select 1 wide variety of more than 2 from the last 8 numbers. The opportunity is calculated as:
P(smallest = 2) = (1/10) * (8/9) * (1/8) = 1/90.
The probability that the smallest drawn range is 3:
Following a comparable approach, the probability is calculated as:
P(smallest = three) = (1/10) * (7/9) * (1/eight) = 1/180.
Continuing this technique, we are able to calculate the chances for the final cases (k = 4,...,10) using the same common sense.
The probabilities for every case will vary relying on the precise situation and the entire range of elements in the set.
It's important to note that this calculation assumes that every wide variety is equally likely to be drawn and that the drawing procedure is without substitute. If the situation or situations differ, the possibilities may additionally range.

Every 4 pages printed in black will cost y cents.
(i) Find an expression for the cost of printing one copy of the newsletter.
(ii) Each newsletter costs 14 cents to print.
Give an example of the cost of printing 4 pages in colour and the cost of printing 4 pages in black.
An educational institution in Shanghai wants to subscribe to this newsletter.
In Singapore, each newsletter costs S$2.20.
The conversion rate is ¥1 = S$0.198 45.
(iii) Without using a calculator, estimate the price of one newsletter in Y.
Each sheet of paper has a mass of 4.5 g.
(iv) How heavy is one copy of the newsletter?
Answers
The correct answer is one copy of the newsletter weighs 216 g.
(i) To find the expression for the cost of printing one copy of the newsletter, we need to consider the cost of printing color pages and black pages separately.
The cost of printing color pages:
For every 4 pages printed in color, it costs x cents.
Since there are 4 color pages in the newsletter, the cost of printing color pages is (x/4) cents.
The cost of printing black pages:
For every 4 pages printed in black, it costs y cents.
Since there are 20 black pages in the newsletter, the cost of printing black pages is (5y) cents.
Therefore, the expression for the cost of printing one copy of the newsletter is:
Cost = (x/4) + (5y)
(ii) Given that each newsletter costs 14 cents to print, we can equate the expression for the cost of printing one copy of the newsletter to 14 cents:
(x/4) + (5y) = 14
(iii) To estimate the price of one newsletter in Y, we need to convert S$2.20 to Y using the conversion rate.
S$2.20 * (¥1/S$0.198 45) = ¥11.083 5
Therefore, the estimated price of one newsletter in Y is approximately ¥11.08.
(iv) To determine the weight of one copy of the newsletter, we need to consider the weight of the paper.
Each sheet of paper has a mass of 4.5 g, and since there are color pages and black pages printed on both sides, we multiply the number of pages by 2.
The weight of one copy of the newsletter is:
Weight = (4 + 20) pages * 2 * 4.5 g
Simplifying:
Weight = 48 * 4.5 g
Therefore, one copy of the newsletter weighs 216 g.

This means that the acrobatic plane has centripetal acceleration, which is directed towards the center of the circular path. The acceleration depends on the speed of the plane, the mass of the plane, and the radius of the circular path. The acceleration can be calculated using the formula a = v2/r where v is the velocity and r is the radius of the circular path.
The given centripetal acceleration, a = 14.7 m/s2, is equal to v2/r. The velocity of the plane is not given, but we can use the fact that the pilot takes 45 seconds to complete the loop to find the velocity. During the loop, the plane travels a distance equal to the circumference of the circular path.
Therefore, the velocity of the plane is given by the formula v = 2πr/t where t is the time taken to complete one loop, which is 45 seconds.
Substituting this value of v into the formula for centripetal acceleration, we have:14.7 = (2πr/45)2Solving for r, we get:r = 77 meters (rounded to the nearest whole number) Therefore, the radius of the loop is 77 meters.
