Given: measure of angle A = 15 degrees, b = 16, and
c = 18. What is the length of a to the nearest tenth?
Answers
Answer:
a ≈ 4.9
Step-by-step explanation:
using the Cosine Rule in Δ ABC
a² = b² + c² - (2bc cosA )
= 16² + 18² - (2 × 16 × 18 × cos15° )
= 256 + 324 - (576cos15° )
= 580 - 576cos15
= 23.6267 ( take square root of both sides )
a = \(\sqrt{23.6267}\)
≈ 4.9 ( to the nearest tenth )

Option A).
Reflection
If we reflect the rug across x or y axis image will be in other quadrants.
Therefore, Reflection is not the answer.
Option B).
Rotation
Rotation of the rug will move it to other quadrants or the size of the image will not cover the scratch mark.
Therefore, Rotation is not the answer.
Option C).
Translation
By shifting the rug to the required place we can cover the scratch mark.
Therefore, Translation will be the answer.
Option D).
Dilation
Dilation of the rug will differ the size.

What is profit?
In accounting, a profit is an income that is given to the owner throughout a successful market producing process. Profitability, which is the owner's primary interest in the income-formation process of market production, is measured by profit. There are several profit metrics that are frequently used.
Let cost price = C
And selling price before reducing = S
Profit for 1 day = S-C
Now, After reducing selling price to = S-0.32
Profit= S - 0.32 - C for 1 day
Profit fall by = (S-C)-(S - 0.32 - C)

Please help!!! Angles!
Answers
Answer:
m∠JKM = 63°
m∠MKL = 27°
Step-by-step explanation:
Since ∠JKL is a right angle. This means that by summing up both m∠JKM and m∠MKL will result in the same as ∠JKL figure. Thus, m∠JKM + m∠MKL = m∠JKL which is 90° by a right angle definition.
\(\displaystyle{\left(12x+3\right)+\left(6x-3\right) = 90}\)
Solve the equation for x:
\(\displaystyle{12x+3+6x-3 = 90}\\\\\displaystyle{18x=90}\\\\\displaystyle{x=5}\)
We know that x = 5. Next, we are going to substitute x = 5 in m∠JKM and m∠MKL. Thus,
m∠JKM = 12(5) + 3 = 60 - 3 = 63°
m∠MKL = 6(5) - 3 = 30 - 3 = 27°

Answers
a) Core size classifications using iso-pore throat radius: No classification for 10 μm, coarse-grained for 2 μm, and fine-grained for 1 μm.
b) Number of flow units: 2. Flow zone indicators (FZI) range from -0.258 to 0.240.
a) Core size classifications using iso-pore throat radius:
To determine the core size classifications, we calculated the iso-pore throat radius (Rt) for each data point using the given porosity (φ) and the formula Rt = 0.14 / φ.
For an iso-pore throat radius of 10 μm, none of the data points had a pore throat radius larger than 10 μm, so no specific classification can be assigned.
For an iso-pore throat radius of 2 μm, data points 1, 2, 3, 4, and 5 had pore throat radii larger than 2 μm. Hence, these data points fall under the coarse-grained classification.
For an iso-pore throat radius of 1 μm, all the data points had pore throat radii larger than 1 μm. Thus, all the data points can be classified as fine-grained.
b) Number of flow units and flow zone indicator:
The hydraulic flow unit approach categorizes reservoir rocks based on their petrophysical properties. We calculated the flow zone indicator (FZI) for each data point using the formula FZI = (log10(k) / φ) - log10(md).
The data points were divided into two flow units based on their FZI values. The FZI values ranged from -0.258 to 0.240.
Therefore, we have two flow units with corresponding FZI values. These flow units help identify different regions within the reservoir with distinct flow characteristics based on the petrophysical properties of the rocks.

The Smith Family is buying a house for $350,000 with a down payment of $70,000 for a 15-year loan, $66 per month insurance, property tax is $230 per month and HOA is $600 per year. Calculate their total monthly payment
Answers
Using monthly payment formula, the Smith Family's total monthly payment is approximately $2,360.99.
What is the Monthly Payment?To calculate the total monthly payment for the Smith Family, we need to consider the mortgage payment, insurance, property tax, and HOA fees.
1. Mortgage Payment:
The loan amount is the house price minus the down payment:
$350,000 - $70,000 = $280,000.
To calculate the monthly mortgage payment, we need to determine the interest rate and loan term. Since you mentioned it's a 15-year loan, we'll assume an interest rate of 4% (which can vary depending on market conditions and the borrower's credit).
We can use a mortgage calculator formula to calculate the monthly payment:
M = P [i(1 + i)ⁿ] / [(1 + i)ⁿ⁻¹]
Where:
M = Monthly mortgage payment
P = Loan amount
i = Monthly interest rate
n = Number of months
The monthly interest rate is the annual interest rate divided by 12, and the loan term is 15 years, which is 180 months.
i = 4% / 12 = 0.00333 (monthly interest rate)
n = 180 (loan term in months)
Plugging in the values into the formula:
M = $280,000 [0.00333(1 + 0.00333)¹⁸⁰] / [(1 + 0.00333)¹⁸⁰⁻¹]
Using a calculator, the monthly mortgage payment comes out to be approximately $2,014.99.
2. Insurance:
The monthly insurance payment is given as $66.
3. Property Tax:
The monthly property tax payment is given as $230.
4. HOA Fees:
The HOA fees are stated as $600 per year. To convert this to a monthly payment, we divide by 12 (months in a year): $600 / 12 = $50 per month.
Now, let's add up all these expenses:
Mortgage payment: $2,014.99
Insurance: $66
Property tax: $230
HOA fees: $50
Total monthly payment = Mortgage payment + Insurance + Property tax + HOA fees
Total monthly payment = $2,014.99 + $66 + $230 + $50
Total monthly payment = $2,360.99

(2 points) Evaluate the definite integrals a) ſ dx dx = X b) c) dx = d) x" dx
Answers
(A) this expression at the limits a and b gives ∫ dx = b + C - a - C = b - a.
(B) ∫[0,π/2] sin(x) dx = -ln|cos(π/2)| + ln|cos(0)| = ln(1) = 0
(C) this expression at the limits 0 and 1 gives:
∫[0,1] x² dx = [(1^3)/3 - (0³)/3] = 1/3
(D) ∫[0,1] xⁿdx = [(1^(n+1))/(n+1) - (0{(n+1))/(n+1)] = 1/(n+1)
a) The definite integral ∫ dx from a to b is equal to the difference between b and a, i.e., ∫ dx = b - a. This result follows from the fundamental theorem of calculus, which states that the definite integral of a function f(x) over an interval [a,b] is equal to the difference between the antiderivative of f evaluated at b and at a. Since the antiderivative of dx is x + C, where C is a constant of integration, we have that ∫ dx = x + C. Evaluating this expression at the limits a and b gives ∫ dx = b + C - a - C = b - a.
b) The definite integral ∫ sin(x) dx from 0 to π/2 can be evaluated using integration by substitution. Let u = cos(x), then du/dx = -sin(x) and dx = du/-sin(x). Substituting into the integral gives:
∫ sin(x) dx = ∫ (-du/u) = -ln|u| + C
Using the substitution u = cos(x), we have u(0) = 1 and u(π/2) = 0, so the definite integral becomes:
∫[0,π/2] sin(x) dx = [-ln|cos(x)|]_[0,π/2] = -ln|cos(π/2)| + ln|cos(0)| = ln(1) = 0
c) The definite integral ∫ x^2 dx from 0 to 1 can be evaluated using the power rule of integration, which states that ∫ x^n dx = (x^(n+1))/(n+1) + C, where C is a constant of integration. Applying this rule to the integral gives:
∫ x^2 dx = (x^3)/3 + C
Evaluating this expression at the limits 0 and 1 gives:
∫[0,1] x^2 dx = [(1^3)/3 - (0^3)/3] = 1/3
d) The definite integral ∫ x^n dx from 0 to 1 can be evaluated using the power rule of integration, which states that ∫ x^n dx = (x^(n+1))/(n+1) + C, where C is a constant of integration. Applying this rule to the integral gives:
∫ x^n dx = (x^(n+1))/(n+1) + C
Evaluating this expression at the limits 0 and 1 gives:
∫[0,1] x^n dx = [(1^(n+1))/(n+1) - (0^(n+1))/(n+1)] = 1/(n+1)
In summary, we evaluated the definite integrals ∫ dx, ∫ sin(x) dx, ∫ x^2 dx, and ∫ x^n dx from a to b using the fundamental theorem of calculus and the power rule of integration. The integrals evaluated to b-a, 0, 1/3, and 1/(n+1), respectively. These results can be used to calculate areas under curves, volumes of solid shapes, and other quantities in calculus and related fields.
In each case, we used a different integration technique to evaluate the definite integral. For ∫ dx, we used the fundamental theorem of calculus, which relates the definite integral of a function to the difference between its antiderivative evaluated at the limits of integration. For ∫ sin(x) dx, we used integration by substitution, which involves replacing a function with a simpler one in order to simplify the integral. For ∫ x^2 dx

A sandwich shop offers five types of sandwiches in three different sizes in four different kinds of bread. You can add six different fillings (tomatoes, pickles, lettuce, onions, jalapenos, mushrooms) for $0.50 each. In how many ways can you personalize your sandwich
Answers
Assuming that you can choose only one type of sandwich, one size, one type of bread, and any combination of fillings, you can personalize your sandwich in the following way : 5 (types of sandwich) x 3 (sizes) x 4 (types of bread) x 2^6 (choices of fillings) = 5 x 3 x 4 x 64 = 3840
So, you can personalize your sandwich in 3840 different ways by choosing one type of sandwich, one size, one type of bread, and any combination of six different fillings.
Hi! I'd be happy to help you determine the number of ways you can personalize your sandwich at this shop.
1. Sandwich type: There are 5 types of sandwiches to choose from.
2. Sandwich size: There are 3 different sizes available.
3. Bread type: You can select from 4 different kinds of bread.
Now, let's consider the fillings. Since there are 6 fillings, each one can either be included or not included. This results in 2 options (yes or no) for each filling.
To calculate the total number of personalized sandwiches, we can multiply the options for each aspect of the sandwich:
5 (types) * 3 (sizes) * 4 (breads) * 2^6 (fillings) = 5 * 3 * 4 * 64 = 3840
Therefore, you can personalize your sandwich in 3840 different ways.

What is the solution to the system of equations y equals 1.5 x 4?
Answers
The solution to the system of equations y = 1.5x - 4 and y = -x is (1.6,-1.6). The correct answer is D.
The solution to the system of equations can be calculate as follows
From the question we can conclude that the equations are :
y = 1.5x - 4
y = -x
to find the value of x and y we can substitute y = -x in the first equation so it became
-x = 1.5x - 4
-1.5x - x = -4
-2.5x = -4
x = 1.6
after we found the value of x we can find the value of y by Substitute
x = 1.6 in y = -x
y = -1.6

jeff paid $4773 for 6 identical printers and 3 identical cameras. ron bought 4 such printers and 6 such cameras and paid $5002 in all. what is the cost of each printer?
Answers
The cost of each printer is $568.
Find cost per unitTo find the cost of each printer, we need to use a system of equations.
Let's call the cost of each printer "p" and the cost of each camera "c".
The first equation we can create is: 6p + 3c = 4773
The second equation we can create is: 4p + 6c = 5002
Now we can use the elimination method to solve for one of the variables.
Let's eliminate the "c" variable by multiplying the first equation by -2: -12p - 6c = -9546
And then add the two equations together: -8p = -4544
Now we can solve for "p" by dividing both sides by -8: p = 568
So the cost of each printer is $568.
To find the cost of each camera, we can plug the value of "p" back into one of the original equations and solve for "c":
6(568) + 3c = 4773
3408 + 3c = 4773
3c = 1365
c = 455
So the cost of each camera is $455.
Therefore, the cost of each printer is $568 and the cost of each camera is $455.

Survey 200 students. 90 take CS, 110 take Mathematics, 60 take Physics, 20 take both CS and Math, 20 take both CS and Physics, 30 take both Math and Physics. How many students take course in all three areas
Answers
There are 10 students taking courses in all three areas.
To solve this problem, we can use the principle of inclusion-exclusion.
First, we add up the number of students taking each course:
90 + 110 + 60 = 260
However, this includes students who are taking more than one-course multiple times.
So, we need to subtract the students who are taking two courses:
260 - (20 + 20 + 30) = 190
This gives us the total number of students taking at least one of the three courses.
To find the number of students taking all three courses, we need to subtract the students who are only taking one or two courses:
190 - (90 + 110 + 60 - 20 - 20 - 30) = 10
Therefore, there are 10 students taking courses in all three areas.
In conclusion, out of the 200 students surveyed, 10 of them take courses in all three areas - computer science, mathematics, and physics. This calculation is important in understanding the interests of students in various fields and can help inform decisions regarding the allocation of resources and the development of new programs.

Answers
Two rays with a common endpoint form an angle. An angle is defined as a geometric figure formed by two rays that share a common endpoint. In other words, an angle is formed when two rays emanating from a common point, and this common point is known as the vertex.
The rays are the sides of the angle, and the angle is measured in degrees. Angles have different measures, ranging from 0 degrees to 360 degrees. The two rays that make up an angle are also called the sides or arms of the angle. The angle is measured in degrees, and the size of the angle depends on the distance between the two sides of the angle that meet at the vertex.
In geometry, an angle can be named in different ways, depending on the context in which it is being used. Angles are essential in mathematics, physics, and other scientific fields, where they are used to measure the rotation of an object, determine the direction of an object, and in other applications involving rays and lines.
