Answer:
The triangles are congruent as per AAS congruence.
Step-by-step explanation:
AAS congruence states that when two triangles are congruent when their two angles are equal and the side not contained between those angles is also equal.
Let us have a look at the given triangles \(\triangle TSU\) and \(\triangle KLM.\)
It is given that they are right angled triangles and following dimensions are also equal:
1. \(\angle T = \angle K = 90^\circ\)
2. \(\angle M = \angle U\)
3. The side not between the angles i.e. the hypotenuse SU = LM
So, the two triangles \(\triangle TSU\) and \(\triangle KLM.\) are congruent as per AAS congruence.
i.e. \(\triangle TSU\) \(\cong\) \(\triangle KLM.\) as per AAS congruence.

Verify the basic identity. What is the domain of validity?cot theta = cos theta csc thetasee image
Solution
Given the function below
\(cot\theta=\cos\theta csc\theta\)Where
\(csc\theta=\frac{1}{\sin\theta}\)\(\begin{gathered} cot\theta=\cos\theta csc\theta \\ cot\theta=\cos\theta\times\frac{1}{\sin} \\ cot\theta=\frac{\cos\theta}{\sin\theta} \end{gathered}\)Also recall that the contangent formula is
\(cot\theta=\frac{\cos\theta}{\sin\theta}\)Thus;
\(\begin{gathered} cot\theta=\cos\theta csc\theta \\ \frac{\cos\theta}{\sin\theta}=\frac{\cos\theta}{\sin\theta} \end{gathered}\)From the above deduction,
sinθ is the denominator,
Hence, the domain of validity is defined for the set of real numbers except for sinθ = 0
a nurse is preparing to administer furosemide 4 mg/kg/day po divided into 2 equal doses daily to a toddler who weighs 22 lb. how many mg should the nurse administer per dose? (fill in the blank with the numeric value only, round the answer to the nearest whole number, and use a leading zero if applicable. do not use a trailing zero.)
The nurse should administer 19.958 mg of furosemide per dose to the toddler.
To use the unitary method, we need to convert the toddler's weight from pounds to kilograms, as the dose is given in mg/kg/day.
1 lb = 0.45359237 kg (conversion factor)
Therefore, the toddler's weight in kilograms is
22 lb x 0.45359237 kg/lb = 9.979 kg (rounded to three decimal places)
Now we can calculate the total daily dose of furosemide for the toddler
4 mg/kg/day x 9.979 kg = 39.916 mg/day (rounded to three decimal places)
Since the dose is divided into 2 equal doses daily, each dose would be half of the total daily dose
39.916 mg/day ÷ 2 = 19.958 mg/dose (rounded to three decimal places)

A password consists of 3 digits (0 - 9) followed by two letters (a-z or A-Z; note: 26 letters in the alphabet). i) How many different passwords are possible if repetition of digits and letters is allowed and passwords are not case sensitive (so 123AB is the same as 123aB)? ii) How many different passwords are possible if repetition of digits and letters is not allowed and the passwords are case-sensitive? (s0 123AB is different from 123aB)? b) A 4-student committee is to be randomly selected from a pool of 5 Biology Majors, 10 Math Majors and 5 Music Majors. 1) What is the probability that all 4 randomly selected students were Math Majors? (State your answer as a reduced fraction OR a decimal rounded to 3 places) ii) Suppose now that the 4 student committee needs to have exactly two math majors. How many different pairs of math majors could be chosen.
a. i. There are 27,040,000 different passwords are possible if repetition of digits and letters is allowed and passwords are not case sensitive (so 123AB is the same as 123aB)
ii. There will be 99,532,800 different passwords are possible if repetition of digits and letters is not allowed and the passwords are case-sensitive
b. i. The probability that all 4 randomly selected students were math majors is 0.520
ii. There are 4,725 different pairs of math majors that could be chosen for the committee.
a. i) There are 10 choices for each of the first 3 digits, and 26 choices for each of the last 2 letters. Since the password is not case sensitive, we can choose either uppercase or lowercase letters, so there are 26 + 26 = 52 choices in total for each letter. Therefore, the total number of different passwords is:
10 x 10 x 10 x 52 x 52 = 27,040,000
ii) There are 10 choices for the first digit, 9 choices for the second digit (since we can't repeat the first digit), 8 choices for the third digit (since we can't repeat the first two digits), and 52 choices for the first letter. For the second letter, there are 51 choices left (since we can't repeat the first letter), but we need to distinguish between uppercase and lowercase letters, so there are 52 x 51 = 2,652 choices for the two letters in total. Therefore, the total number of different passwords is:
10 x 9 x 8 x 52 x 2,652 = 99,532,800
b) i) The total number of ways to select a 4-student committee from 20 students is:
20 choose 4 = 4,845
The number of ways to select a committee consisting of 4 math majors is:
10 choose 4 = 2,520
Therefore, the probability that all 4 randomly selected students were math majors is:
2,520 / 4,845 = 0.520
ii) The number of ways to select a 4-student committee with exactly two math majors is:
(10 choose 2) x (10 choose 2) x (15 choose 0) = 4,725
(We choose 2 math majors from 10, and 2 non-math majors from 15, since there are 5 biology majors and 5 music majors to choose from.)
Therefore, there are 4,725 different pairs of math majors that could be chosen for the committee.

What type of move takes Figure A to Figure B?*
Answer: Rotation
Step-by-step explanation:
From the figure , we can observe that both figure A and b are absolutely congruent.
To translate a figure to make congruent images , we use rigid motions (Translation, Reflection, Rotation)
It is Rotation because of we move Figure A 180 degrees clockwise about the fixed point O, we will get Figure B .
It cannot be reflection because both figures are not mirror images.
It cannot be translation because all points on Figure A is not moving , as point O remained at same position throughout this which is not possible in translation.
what is the volume in cubic inches of a pyramid with a square base if the primeter of the base is 60 inches and the height is 20 inches
V = (1/3)(225)(20) = 1500 cubic inches. The volume of a pyramid with a square base can be calculated using the formula V = (1/3)Bh, where B is the area of the base and h is the height of the pyramid.
To find the area of the base, we need to first find the length of one side of the square base by dividing the perimeter (60 inches) by 4, which gives us 15 inches. Then, we can find the area of the base by squaring this length, which gives us 225 square inches. Plugging in the values of B = 225 and h = 20 into the formula, we get V = (1/3)(225)(20) = 1500 cubic inches.
we used the formula for the volume of a pyramid with a square base, which is V = (1/3)Bh. We then found the area of the base by finding the length of one side of the square base (perimeter divided by 4) and squaring it. Finally, we plugged in the values of the base area and height into the formula to get the volume in cubic inches.

Two events are not independent if d) one event affects the likelihood of another event. This means that the occurrence of one event changes the probability of the other event happening.
For example, if flipping a coin, the probability of getting heads is 0.5, but if we know that the coin is weighted towards tails, the probability of getting heads will decrease, this means that the coin flip and the weight of the coin are not independent events because the weight of the coin affects the likelihood of getting heads.

You decide to invest in a period annuity that offers 4.5% APR compounded
monthly for 20 years. How much money will you need to invest if your desired
yearly income is $42,000?
OA. $553,229.03
B. $450,000.00
C. $420,000.00
D. $568,793.79
Answer: To calculate the amount of money you would need to invest in a period annuity that offers 4.5% APR compounded monthly for 20 years to receive an annual income of $42,000, you can use the following formula:
PV = A * [(1 - (1+r)^(-n)) / r]
where:
PV = present value (amount of money you need to invest)
A = annual income ($42,000 in this case)
r = interest rate per period (4.5% APR compounded monthly, or 0.045/12 = 0.00375 per month)
n = total number of periods (20 years x 12 months per year = 240 months)
Plugging in the numbers, we get:
PV = $42,000 * [(1 - (1+0.00375)^(-240)) / 0.00375]
PV = $553,229.03
Therefore, the answer is (A) $553,229.03.

y = 2x^2 + 12x + 14
Step-by-step explanation:
Write this equation in standard form. Start by performing the exponentiation:
y = 2(x^2 + 6x + 9) - 4
Perform the indicated multiplication:
y = 2x^2 + 12x + 18 - 4, or
y = 2x^2 + 12x + 14: This is the quadratic function in standard form.
The value of the quadratic function in standard form is,
⇒ f (x) = 2x² + 12x + 14
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
The function is,
⇒ f (x) = 2 (x + 3)² - 4
Now, We get;
The value of the quadratic function in standard form is,
⇒ f (x) = 2 (x + 3)² - 4
⇒ f (x) = 2 (x² + 9 + 6x) - 4
⇒ f (x) = 2x² + 18 + 12x - 4
⇒ f (x) = 2x² + 12x + 14
Thus, The value of the quadratic function in standard form is,
⇒ f (x) = 2x² + 12x + 14

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)
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.

Answer:
Step-by-step explanation:
Based on the calculations, the sequence defined by the given function are 0.75, 1.1, 1.45, 1.80 and 2.15.
How to create the terms of the sequence?
In this exercise, you're required to create the first five (5) terms of the sequence defined by the given function as follows:
For the first term, we have:
f(1) = 0.75
For the second term, we have:
f(2) = f(2-1) + 0.35
f(2) = 0.75 + 0.35
f(2) = 1.1.
For the third term, we have:
f(3) = f(3-1) + 0.35
f(3) = 1.1 + 0.35
f(3) = 1.45.
For the fourth term, we have:
f(4) = f(3-1) + 0.35
f(4) = 1.45 + 0.35
f(4) = 1.80.
For the fifth term, we have:
f(5) = f(3-1) + 0.35
f(5) = 1.80 + 0.35
f(5) = 2.15.
Therefore, the sequence defined by the given function are 0.75, 1.1, 1.45, 1.80 and 2.15.
Given the demand function P = -QD2–2QD+ 64, and the supply function P = QS2–2QS+ 14.
a/Assuming pure competition, find the consumer’s surplus and the producer’s surplus;
b/ Explain the meaning of the values of the surpluses as found in a question/
The positive value of producer surplus indicates that the producers are willing to sell the good at the given price of $26, and they are making $16 from the sale of the good.
a) The given demand function and supply function are:
P = -QD2 – 2QD + 64 and P = QS2 – 2QS + 14 respectively. When assuming pure competition, the equilibrium price can be found by equating the demand function and supply function to each other. Equating,
-QD2 – 2QD + 64 = QS2 – 2QS + 14.
QD2 + 2QD + QS2 – 2QS = 50.
QD2 + 2QD + QS2 – 2QS – 50 = 0.
Now we can solve for equilibrium quantity:
QS2 + QD2 = 50 – 2(QD – QS)
2.QS2 + QD2 = 50.
Now solving further, QS = 4 and QD = 6.
Now, substituting these equilibrium values into the demand function and supply function, we can calculate the equilibrium price:
P = -QD2 – 2QD + 64 = -6(6) – 2(6) + 64 = 26.P = QS2 – 2QS + 14 = 4(4) – 2(4) + 14 = 18.
As a result, consumer surplus is:
CS = 1/2 (6-26) (6) = $-60
Producer surplus is:
PS = 1/2 (26-18) (4) = $16
b) Consumer surplus is defined as the benefit received by the consumers from purchasing a good at a price lower than what they are willing to pay. It measures the difference between the actual price paid by the consumers and the maximum price they are willing to pay for a good. In this case, the negative value of consumer surplus indicates that the consumers are not willing to pay the given price of $26. They are losing $60 to purchase the good.Producer surplus is the difference between the price at which a producer sells a good and the minimum price that the producer is willing to accept for the good. In this case, the positive value of producer surplus indicates that the producers are willing to sell the good at the given price of $26, and they are making $16 from the sale of the good.

It will take approximately 11 minutes and 14 seconds (to the nearest minute) for the Baxter boys to prepare 131 papers. Given that the Baxter boys can prepare 35 papers in 3 minutes, we can set up a proportion to solve for the time it will take to prepare 131 papers.
First, let's set up the proportion using the information given about the rate of working:
35 papers / 3 minutes = 131 papers / x minutes
To solve for x, we can cross-multiply and then divide:
35 * x = 3 * 131
35x = 393
x = 393 / 35
x ≈ 11.229
