find value of x!!! this is geometry

Answer:

\(=2/4=1/2\)

Step-by-step explanation:

Answer:

1.1.1: A dozen means 12, so approximately a dozen of mangoes will cost:

12 x R7.80 = R93.60

1.1.2: If the cost of one mango is increased by 2%, the new cost of one mango will be:

R7.80 x 1.02 = R7.96

1.2.1: If the farmer reduces the cost of each mango by 5.5%, the new cost of one mango will be:

R7.80 x 0.945 = R7.37 (rounded to two decimal places)

To show the calculation:

5.5% of R7.80 = 0.055 x R7.80 = R0.429

The reduced price of each mango = R7.80 - R0.429 = R7.371

Rounded to two decimal places, the reduced price of each mango is approximately equal to R7.37.

The cost of a dozen of mangoes is $93.60.

The new cost of one mango is 7.956.

The reduced price of each mango is approximately $7.37.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

A dozen of mangoes means 12 mangoes.

So, the cost of a dozen of mangoes can be calculated by multiplying the cost of one mango by 12:

Cost of a dozen of mangoes.

= 12 x 7.80

= $93.60

So, it will cost approximately $93.60 for a dozen of mangoes.

If the cost of one mango is increased by 2%, then the new cost of one mango can be calculated as follows:

The new cost of one mango.

= 7.80 + (2/100) x 7.80

= 7.956

So, the cost of one mango after the increase is approximately $7.96.

If the farmer has decided to reduce the cost of each mango by 5.5%, then the new cost of one mango can be calculated as follows:

The new cost of one mango.

= 7.80 - (5.5/100) x 7.80

= 7.3716

Rounding this answer to two decimal places gives:

The new cost of one mango = $7.37

So, the reduced price of each mango is approximately $7.37.

Thus,

The cost of a dozen of mangoes is $93.60.

The new cost of one mango is 7.956.

The reduced price of each mango is approximately $7.37.

A function of the type A cos(Lx) is not an appropriate solution for the particle in a one-dimensional box since it does not satisfy the required boundary conditions for the system.

In one-dimensional box case, the particle is confined within a definite region, represented by the interval [0, L]. This boundary conditions requires that the wave function of a particle must be zero, i.e., ψ(0) = ψ(L) = 0. This allows that the probability density of finding the particle outside the box is also zero.

The function of the type A cos (Lx) does not satisfy these boundary conditions. If x is 0, the function evaluates to A cos(0) = A, which is not zero. Similarly, when x is L, the function evaluates to A cos(L), which is usually not zero unless L is an integer multiple of π.

It has physical interpretations related to the quantization of energy levels in the finite system, which is a fundamental aspect of quantum mechanics.

By applying the concept of the inverse of a function and algebraic handling, we conclude that the inverse of f(x) = (- 2 · x + 2)/(x + 7) is g(x) = (- 7 · x + 2)/(x + 2).

In this question we have a rational function f(x) and finding its inverse consists in clearing x in terms of f(x). Prior any algebraic handling, we need to apply the following substitutions:

\(x \to y\)

\(f(x) \to x\)

\(x = \frac{-2\cdot y + 2}{y+7}\)

x · (y + 7) = - 2 · y + 2

x · y + 7 · x = - 2 · y + 2

2 · y + x · y = - 7 · x + 2

y · (2 + x) = - 7 · x + 2

\(g(x) = \frac{- 7\cdot x + 2}{x + 2}\)

By applying the concept of the inverse of a function and algebraic handling, we conclude that the inverse of f(x) = (- 2 · x + 2)/(x + 7) is g(x) = (- 7 · x + 2)/(x + 2).

Answer:

\((\ln(5), 19-5\ln(5))\)

Step-by-step explanation:

The line can be represented as y=5x-8, so the slope of the line is 5.

The derivative of the curve is:

\(\frac{d}{dx} [9+2e^x-5x]\\=\frac{d}{dx} [9]+\frac{d}{dx} [2e^x]-\frac{d}{dx} [5x]\\=2e^x-5\\\)

We need to set that equal to 5 to find the x coordinate of our desired point

\(2e^x-5=5\\2e^x=10\\e^x=5\\x=\ln(5)\)

Now, just plug in x in the curve to solve for y:

\(9+2e^{\ln(5) } -5\ln(5) = y\\9+10-5\ln(5)=y\\19-5\ln(5)=y\)

Line 5x y = 8 has a slope of 5. This means that the tangent line that runs parallel to this line must also have a slope of 5.

To solve this equation

dy/dx = 2ex 5 is the derivative of the function y = 9 + 2ex 5x. Consequently, 2ex 5 is equal to the slope of the tangent line at any location.

When we set the slope of the tangent line to 5, we obtain:

2ex − 5 = 5

2ex = 10

e^x = 5

Taking the natural logarithm of both sides, we get:

ln(e^x) = ln(5)

x = ln(5)

Therefore, ln(5) is the x-coordinate of the crossing point.

We can enter this value of x into the original function to determine the y-coordinate:

y = 9 + 2e^(ln(5)) − 5(ln(5))

y = 9 + 10 − 5ln(5)

y = 15 − 5ln(5)

As a result, the intersection is at (ln(5), 15 5ln(5)).

To sum up, (ln(5), 15 5ln(5)) is the point on the curve y = 9 + 2ex 5x where the tangent line is parallel to the line 5x y = 8.

Step-by-step explanation:

The angle measures are given as follows:

a) m < 4 = 117º.

b) m < 8 = 117º.

Angle 4 forms a linear pair with the angle of 63º, as they are opposite by the transversal line, hence they are supplementary angles, meaning that the sum of their measures is of 180º.

Hence the measure of angle 4 is obtained as follows:

m < 4 + 63º = 180º.

m < 4 = 117º.

Angle 8 is a corresponding angle to angle 4, meaning that they are on the same position relative to the transversal line, and relative to different parallel lines.

Corresponding angles are congruent, hence:

m < 8 = m < 4 = 117º.

The modified function will be  f(p²) = \(p^{4}\) - 3p² +1.

What is a function?
A function is a special kind of relation where each input has exactly one output. In other words, for each input value, the function returns exactly one value. A relation instead of a function is depicted in the above graph as one is mapped to intermediate values. However, if someone were instead mapped to the a single value, the relationship described above would change into a function. Furthermore, output values could match input values exactly. The function machine receives the x-values as input. After finishing its operations, the function machine outputs the y-values. Any function may be the one within.

The given function f(x) = x²-3x+1

So we can replace x ---→ p²

b) By strong induction, any amount of postage worth 24 cents or more can be made from 7-cent or 5-cent stamps.

c) By strong induction, any amount of postage worth 12 cents or more can be made from 3-cent or 7-cent stamps.

a. Prove that any amount of postage worth 8 cents or more can be made from 3-cent or 5-cent stamps.

Base case: For postage worth 8 cents, we can use two 4-cent stamps, which can be made using a combination of one 3-cent stamp and one 5-cent stamp.

Induction hypothesis: Assume that any amount of postage worth k cents or less, where k is greater than or equal to 8, can be made from 3-cent or 5-cent stamps.

Induction step: Consider any amount of postage worth (k+1) cents. Since k is greater than or equal to 8, we can use the induction hypothesis to make k cents using 3-cent or 5-cent stamps. Then, we can add one more stamp to make (k+1) cents. If the last stamp we added was a 3-cent stamp, we can replace it with a 5-cent stamp to get the same value. If the last stamp we added was a 5-cent stamp, we can replace it with two 3-cent stamps to get the same value. Therefore, any amount of postage worth (k+1) cents can be made from 3-cent or 5-cent stamps.

b. Prove that any amount of postage worth 24 cents or more can be made from 7-cent or 5-cent stamps.

Base case: For postage worth 24 cents, we can use three 8-cent stamps, which can be made using a combination of one 7-cent stamp and one 5-cent stamp.

Induction hypothesis: Assume that any amount of postage worth k cents or less, where k is greater than or equal to 24, can be made from 7-cent or 5-cent stamps.

Induction step: Consider any amount of postage worth (k+1) cents. Since k is greater than or equal to 24, we can use the induction hypothesis to make k cents using 7-cent or 5-cent stamps. Then, we can add one more stamp to make (k+1) cents. If the last stamp we added was a 5-cent stamp, we can replace it with two 7-cent stamps to get the same value. If the last stamp we added was a 7-cent stamp, we can replace it with three 5-cent stamps to get the same value. Therefore, any amount of postage worth (k+1) cents can be made from 7-cent or 5-cent stamps.

c. Prove that any amount of postage worth 12 cents or more can be made from 3-cent or 7-cent stamps.

Base case: For postage worth 12 cents, we can use one 3-cent stamp and three 3-cent stamps, which can be made using a combination of two 7-cent stamps.

Induction hypothesis: Assume that any amount of postage worth k cents or less, where k is greater than or equal to 12, can be made from 3-cent or 7-cent stamps.

Induction step: Consider any amount of postage worth (k+1) cents. Since k is greater than or equal to 12, we can use the induction hypothesis to make k cents using 3-cent or 7-cent stamps. Then, we can add one more stamp to make (k+1) cents. If the last stamp we added was a 3-cent stamp, we can replace it with two 7-cent stamps to get the same value.

Predatory pricing. Predatory pricing occurs when a dominant firm intentionally sets its prices below the cost of production or below its competitors' prices in order to eliminate competition and deter new entrants into the market.

In this scenario, Firm A, the monopolist, engages in predatory pricing by reducing its prices in response to the entry of Firm B into the market. The aim is to make it financially difficult for Firm B to survive and eventually force it out of the market. By lowering its prices, Firm A hopes to attract customers away from Firm B and regain its monopoly power.

Predatory pricing is considered an anti-competitive practice and is often illegal in many jurisdictions. It can harm competition, limit consumer choice, and lead to higher prices in the long run. Regulatory bodies and competition authorities closely monitor such practices and may take legal action against firms found engaging in predatory pricing.

Overall, predatory pricing is a strategy employed by dominant firms to protect or strengthen their market position by driving out competitors. However, it is important for regulators to enforce antitrust laws to ensure fair competition and protect the interests of consumers and smaller market players.

Answer: \(x < -\frac{24}{5}\)

Step-by-step explanation:

You have:

\(-\frac{5}{6} x-3 > 1\)

Add 3 to both sides to get:

\(-\frac{5}{6} x > 4\)

Multiply both sides by 6 to get:

\(-{5} x > 24\)

Divide both sides by -5. When you divide an inequality by a negative number, you must switch the signs. Therefore:

\(x < -\frac{24}{5}\)

Answer:

The equation is saying multiply or add negative 5/6 to x, then subtract by positive 3 which makes the number go upwards, but not making it positive, and lastly, the equation is saying the result will be greater than 1.

One of the values for x is 5, because...

\(-\frac{5}{6} * 5 = -4\frac{1}{6} - 3 = 7\frac{1}{6} > 1\)

With that information, the statement is now complete and true. If you make 5 or anything more than 5 the value for x, the statement will still be true.

Note that I just used 5 as one of the solutions. There are many more than that.

The unreasonable effectiveness of mathematics in the natural sciences is a well-known phenomenon that has been discussed by many scientists and philosophers. The idea is that mathematical concepts and models seem to be remarkably successful in describing and predicting the behavior of the natural world. This effectiveness is often seen as evidence of the power and universality of mathematics.

However, whether this effect gives any support to the hypothesis that our universe was designed is a matter of debate. Some argue that the precise mathematical relationships that govern the universe are evidence of a designer, while others suggest that the success of mathematics in describing the natural world is simply a result of the human mind's ability to perceive patterns and make predictions based on those patterns.

Ultimately, the question of whether the unreasonable effectiveness of mathematics supports the hypothesis of a designed universe is a philosophical and theological one, and there is no definitive answer. Some people may find the argument convincing, while others may not. It is up to each individual to weigh the evidence and come to their own conclusions.
