Answer:
$4
Step-by-step explanation:
Let's denote the price of an apple by "a" and the price of a mango by "m". Then we can set up two equations based on the information given in the problem:
"The total price of 3 mangoes and 6 apples is $42"
mangoes are three times apples in this case.
3m + 6a = 42
"The price of a mango is $2 less than 2 times that of an apple"
m = 2a - 2
Now we can substitute equation 2 into equation 1 and solve for "a":
3(2a - 2) + 6a = 42
6a - 6 + 6a = 42
12a = 48
a = 4
Therefore, the price of an apple is $4.

. ΔABC is a right triangle, with ∠C being the right angle. m∠A = 51°, b = 8, find a.
In the given right triangle the length of side a is approximately 9.92 units.
Define the right triangle.A right triangle is a variety of triangles with a 90-degree angle (a right angle). The junction of the triangle's two legs, or the sides that meet at a right angle, creates this angle. The hypotenuse, which is always located opposite the right angle, is the third side of a right triangle.
A key characteristic of right triangles is the Pythagorean theorem, which asserts that the square of the hypotenuse is equal to the sum of the squares of the two legs of a right triangle.
We can use the trigonometric ratios of sine, cosine, and tangent to solve for the missing side of a right triangle. Since we are given the measure of one acute angle and the length of the side opposite that angle, we can use the tangent ratio:
tan A = opposite/adjacent
tan 51° = a/8
Multiplying both sides by 8:
a = 8 tan 51°
Using a calculator, we find that:
a ≈ 9.92
Therefore, the length of side a is approximately 9.92 units.

Answer:
Step-by-step explanation:
We can start by combining the two fractions by finding a common denominator:
sin(a)/(1+cos(a)) + (1+cos(a))/sin(a)
= sin^2(a)/(sin(a)(1+cos(a))) + (1+cos(a))^2/((1+cos(a))sin(a))
= sin^2(a) + (1+cos(a))^2 / (sin(a)(1+cos(a)))^2
= (sin^2(a) + 1 + 2cos(a) + cos^2(a)) / (sin^2(a) + 2sin(a)cos(a) + cos^2(a))
= (2 + 2cos(a)) / (sin(a) + cos(a))^2
= 2(1+cos(a)) / (sin(a) + cos(a))^2
= 2(cos^2(a/2)/sin^2(a/2)) / (sin(a/2) + cos(a/2))^2 (using the half-angle identities)
= 2tan^2(a/2) / (sin(a/2) + cos(a/2))^2
This expression cannot be simplified further without additional information or context.

The cost of packing a box of chocolates is given by 1/4 x2, where x is the number of chocolates (a box can never have fewer than 3 chocolates). If the weight of a box of chocolates is given by x + 2, what is the cost of packaging per weight unit?
Using the unitary method, we found that the cost of packing the unit weight of the chocolate box is [tex]\frac{x^2}{4(x+2)}[/tex] , for x ≥ 3.
What is meant by the unitary method?
The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, and then multiplying that value to determine the required value. Recognizing the units and values is crucial when using the unitary technique to a problem.
Always write the items that need to be computed on the right side and the things that are known on the left side to simplify things.
The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
Given,
The cost of packing a box of chocolates = 1/4 * x²
where x = Number of chocolates and x ≥ 3 for one box.
Weight of a box of chocolates = x + 2
We are asked to find the cost of packing 1 unit weight of chocolates.
This can be found using the unitary method.
Cost of unit weight = Cost of packing a whole box / Total weight of the box.
= (1/4 * x²) / (x + 2)
= [tex]\frac{x^2}{4(x+2)}[/tex] , for x ≥ 3
Now in the figure below, we are given four options.
On solving the first option we get the above equation as follows.
[tex]\frac{1}{4} x - \frac{1}{2} + \frac{1}{x+2}[/tex]
Taking LCM and making the same denominator for all.
[tex]\frac{x(x+2) - 2(x+2) +4 }{4(x+2)} = \frac{x^2+2x-2x-4+4}{4(x+2)} = \frac{x^2}{4(x+2)}[/tex]
Therefore using the unitary method, we found that the cost of packing the unit weight of the chocolate box is [tex]\frac{x^2}{4(x+2)}[/tex] , for x ≥ 3.

pounds of zucchini. Because David has a _______ opportunity cost of producing watermelon than Morgan, _______ has a comparative advantage in the production of watermelon, and ______ has a comparative advantage in the production of zucchini.
David's opportunity cost of producing 1 pound of watermelon is 4 pounds of zucchini, whereas Morgan's opportunity cost of producing 1 pound of watermelon is 3 pounds of zucchini. Because David has a higher opportunity cost of producing watermelon than Morgan, Morgan has a comparative advantage in the production of watermelon, and David has a comparative advantage in the production of zucchini.
What is opportunity cost?
Opportunity costs are the possible advantages that a person, investor, or company forgoes while deciding between two options. Opportunity costs are by definition invisible, making it simple to ignore them.
The best input combinations to achieve the highest level of output are displayed on the production potential frontier.
The individual who has a lower opportunity cost in output than another individual enjoys a comparative production advantage.
David's watermelon production -
54 units watermelon = 216 units zucchini
1 unit watermelon = 216/54 units zucchini
1 unit watermelon = 4 units zucchini
Morgan's watermelon production -
108 units watermelon = 324 units zucchini
1 unit watermelon = 324/108 units zucchini
1 unit watermelon = 3 units zucchini
Morgan has absolute advantage in production of Zucchini and Morgan has also absolute advantage in production of watermelon.
Therefore, David's opportunity cost of 1 pound of watermelon is 4 pound of Zucchini and Morgan's opportunity cost of 1 pound of watermelon is 3 pound of Zucchini.

Let f be the function given by f(x)=x/x+2. What are the values of c that satisfy the mean value theorem
The Mean Value Theorem states that if a function f is continuous on the interval [a,b] and differentiable on (a,b), then there exists at least one c in the interval (a,b) such that
f'(c) = (f(b) - f(a)) / (b - a)
For the function f(x) = x/x+2, we can set
f(a) = a/a+2 and f(b) = b/b+2
Therefore, the equation we need to solve is:
(b/b+2 - a/a+2) / (b - a) = c/(c+2)
After rearranging, we get:
(b-a)c + 2(a-b) = 0
Solving this, we find that c = 2(b-a) / (a-b)
Therefore, the values of c that satisfy the Mean Value Theorem for the given function f(x) = x/x+2 are c = 2(b-a) / (a-b).

You can locate the area by lining up all the numbers.
Here,
The range of a function is the set of all possible output values. Let's consider each function separately:
f(x) = |x-3|
The absolute value of any number is always non-negative, so the range of f(x) is [0, ∞).
g(x) = -(x-4)²-3
The square of any real number is always non-negative, so the range of the function -(x-4)² is (-∞, 0]. Subtracting 3 from this range gives the range of g(x) as (-∞, -3].
h(x) = -7
The output of h(x) is always -7, so the range of h(x) is {-7} (a singleton set containing only the number -7).
Putting it all together, the range of the composite function f(g(h(x))) is [0, ∞).

interpolating polynomial. f(x) = ln x
Data points at x = 1, x2 = 4, x3 = 6 and x, = 5 were used to estimate in 2 with a third-order Newton's
Using third-order Newton's interpolating a polynomial the value of f(2) is (25ln(2))/9.
What is the value of f(2)To estimate the value of f(2) using a third-order Newton's interpolating polynomial with the given data points, we first need to calculate the divided differences. The divided differences are defined as:
f[xi] = f(xi) for i = 1, 2, 3
f[x1,x2] = (f[x2] - f[x1]) / (x2 - x1) = (ln(4) - ln(1)) / (4 - 1) = ln(4) / 3
f[x2,x3] = (f[x3] - f[x2]) / (x3 - x2) = (ln(6) - ln(4)) / (6 - 4) = ln(3) / 2
f[x1,x2,x3] = (f[x2,x3] - f[x1,x2]) / (x3 - x1) = ((ln(3) / 2) - (ln(4) / 3)) / (6 - 1) = -0.018
Using these divided differences, we can write the third-order Newton's interpolating polynomial as:
f(x) = f[x1] + f[x1,x2](x - x1) + f[x1,x2,x3](x - x1)(x - x2) + f[x1,x2,x3,x4](x - x1)(x - x2)(x - x3)
Substituting the values of the data points and the divided differences we calculated, we get:
f(x) = ln(1) + ln(4)/3 (x - 1) - 0.018 (x - 1)(x - 4)
Simplifying this expression, we get:
f(x) = ln(1) + (ln(4)/3)x - (11ln(2)/9) + (ln(2)/9)x^2
To estimate f(2), we plug in x = 2:
f(2) = ln(1) + (ln(4)/3)(2) - (11ln(2)/9) + (ln(2)/9)(2)^2
f(2) = 2ln(2) - (11ln(2)/9) + (ln(2)/9)(4)

The total annual income from both investment is
(14x -65000)/100
What is interest?Interest is the price you pay to borrow money or the cost you charge to lend money. Interest is most often reflected as an annual percentage of the amount of a loan. This percentage is known as the interest rate on the loan.
I = x× 9/100

What is Statistic?The statistic is the study of mathematics that deals with relations between comprehensive data.
Here,
To calculate the mean, variance, and standard deviation of the ages of the 12 students, we first need to find the sum of the ages:
Sum = 16 + 17 + 18 + (16/0.5) + 17 + 18 + 19 + 17 + 17 + 13 + (17/2/2) + 16
= 16 + 17 + 18 + 32 + 17 + 18 + 19 + 17 + 17 + 13 + 4.25 + 16
= 204.25
Mean = Sum / Number of students = 204.25 / 12 ≈ 17.02 years
To calculate the variance, we need to subtract the mean from each age, square the differences, add up the squares, and divide by the number of students minus one:
Variance = [ (16 - 17.02)² + (17 - 17.02)² + ... + (16 - 17.02)² ] / (12 - 1)
= [ 0.16 + 1.96 + ... + 0.16 ] / 11
= 37.41
Finally, we can calculate the standard deviation by taking the square root of the variance:
Standard deviation = √(Variance) ≈ 6.117
Therefore, the mean age of the 12 students is approximately 17.02 years, the variance is 37.41, and the standard deviation is approximately 6.117 years.

The value of the composition of functions are
a) f o g ( 5 ) = 1315
b) g o f ( 5 ) = 59
What is Composition of functions?Evaluation of a function at the value of another function is known as Composition of function. A function composition is a process in which two functions, f and g, form a new function, h, in such a way that h(x) = g(f(x)). This signifies that function g is being applied to the function x. So, in essence, a function is applied to the output of another function.
Given data ,
Let the value of the the function be f ( x ) = x² + 6x
Let the value of the function g ( x ) = x + 4
Now , the composition of functions is given by
f o g ( 5 ) is given by
g ( 5 ) = 5 + 4 = 9
So , the value of f ( 9 ) = ( 9 )² + 6 ( 9 ) = 81 + 54 = 135
Therefore , the value of f o g ( 5 ) = 135
Now , the composition of functions is given by
g o f ( 5 ) is given by
f ( 5 ) = ( 5 )² + 6 ( 5 ) = 25 + 30 = 55
Now , the value of g ( 55 ) = 55 + 4 = 59
Therefore , the value of g o f ( 5 ) = 59
Hence , the composition of functions are solved

How to solve the system of equationsFrom the question, we have the following parameters that can be used in our computation:
12x + 9y = 6
7x + 6y = −1
Multiply (2) by 1.5
So, we have the following representation
12x + 9y = 6
10.5x + 9y = −1.5
Subtract the equations to eliminate y
1.5x = 7.5
So, we have
x = 5
Recall that
12x + 9y = 6
So, we have
60 + 9y = 6
This gives
9y = -54
Divide
y = -6
SO, the value of y is -6
