What’s the area of 5feet 12feet and 13feet, using 4(bxh)

Answers

Answer 1

The area of 5feet 12feet and 13feet, 30 square feet

Area calculation.

the formula 4(bxh) is used to calculate the area of a rectangle, not a triangle. However, the dimensions 5 feet, 12 feet, and 13 feet are actually the sides of a right triangle (known as a Pythagorean triple), so we can use the formula for the area of a right triangle:

Area = 1/2 x base x height

where the base and height are the two legs of the right triangle.

Using the Pythagorean theorem, we can determine that the legs of the triangle are 5 feet and 12 feet, and the hypotenuse is 13 feet. Therefore, the area of the triangle is:

Area = 1/2 x 5 feet x 12 feet

Area = 30 square feet

when a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam 10 feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)

Answers

The intensity of the beam 10 feet below the surface can be calculated using Beer-Lambert's law, which states that the rate of decrease in intensity of light through a transparent medium is proportional to the thickness of the medium. This means that the intensity i of the beam at a depth t below the surface is given by the equation i = i0 * e^(-kt), where i0 is the initial intensity of the incident beam, k is a constant, and e is Euler's number.
For the given scenario, we know that the intensity at a depth of 3 feet is 25% of the initial intensity i0. Substituting the known values into the equation, we can calculate the value of k:
i = i0 * e^(-3k)
0.25i0 = i0 * e^(-3k)
0.25 = e^(-3k)
ln(0.25) = -3k
k = ln(0.25) / -3
k = 0.0451
Therefore, the intensity of the beam 10 feet below the surface can be calculated as follows:
i = i0 * e^(-0.0451 * 10)
i = i0 * e^(-0.451)
i = 0.6139i0

Rounding any constants or coefficients to five decimal places, the intensity of the beam 10 feet below the surface is 0.6139i0.

If the car wash has a demand of 14 cars per hour, what is the utilization of the machine that

Answers

The utilization of the machines is the processing time for the machines divided by the cycle time: 14 / 20 = 0.7 or 70%.

The bottleneck resource in this process is the hand-dry step, as it is the only step that is performed manually and thus has limited capacity. The processing time for the hand-dry step is 6 minutes per car, which is longer than any of the other steps.

To calculate the flow rate of the process, we need to determine the cycle time, which is the time it takes to process one car through all the steps. The cycle time is the sum of the processing times for all the steps, which is 2 + 7 + 1 + 4 + 6 = 20 minutes per car.

To convert this to customers per hour, we divide the number of minutes per hour (60) by the cycle time: 60 / 20 = 3 customers per hour.

Therefore, the flow rate of the process is 14 cars per hour x 3 customers per hour = 42 customers per hour.

To calculate the utilization of the machines, we need to calculate the total time that the machines are processing cars. Since all the steps except for the hand-dry step are performed by dedicated machines, the total processing time for the machines is 2 + 7 + 1 + 4 = 14 minutes per car.

Therefore, the utilization of the machines is the processing time for the machines divided by the cycle time: 14 / 20 = 0.7 or 70%.

Can 3 feet, 3 feet and 7 feet create a triangle explain why or why not

Answers

The given lengths of 3 feet, 3 feet, and 7 feet cannot form a triangle because they do not satisfy the Triangle Inequality Theorem, which is the sum of the lengths of any two sides is greater than the length of the third side.

To form a triangle, the sum of the lengths of any two sides of the triangle must be greater than the length of the third side. This is known as the Triangle Inequality Theorem.

Let's apply this theorem to the given lengths of 3 feet, 3 feet, and 7 feet:

The sum of the first two sides is 3 + 3 = 6 feet, which is less than the length of the third side of 7 feet. So, the first two sides cannot form a triangle.

The sum of the first and third sides is 3 + 7 = 10 feet, which is greater than the length of the second side of 3 feet. However, the sum of the second and third sides is 3 + 7 = 10 feet, which is also greater than the length of the first side of 3 feet.

Therefore, neither of the two combinations of sides satisfy the Triangle Inequality Theorem, and so it is impossible to form a triangle with sides of 3 feet, 3 feet, and 7 feet.

The company uses the function r defined by r(x)=x⋅(1,000−2x) to model the expected revenue, in dollars, from selling cell phones at x dollars each. At what price should the company sell their phones to get the maximum revenue? x i tercept

Answers

The company should sell their phones for $250 each to get the maximum revenue.

What do you mean by maximum revenue?

Maximum revenue refers to the highest possible amount of income that can be generated from a particular product or service. In the context of the given problem, it means finding the price at which the company can sell its cell phones to earn the highest amount of revenue.

Finding the price at which the company should sell their phones to get the maximum revenue:

We need to find the vertex of the parabolic function [tex]r(x)=x(1,000-2x)[/tex], which represents the revenue as a function of the selling price.

To find the vertex of the function r(x), we need to first rewrite it in standard form by expanding the product:

[tex]r(x) = 1000x - 2x^2[/tex]

Now we can see that the function is a quadratic polynomial in standard form, with [tex]a=-2, b=1000[/tex], and [tex]c=0[/tex]. To find the x-coordinate of the vertex, we can use the formula:

[tex]x = -b / (2a)[/tex]

Substituting the values of a and b, we get:

[tex]x = -1000 / (2\times(-2)) = 250[/tex]

Therefore, the company should sell their phones for $250 each to get the maximum revenue. To find the maximum revenue, we can substitute this value of x into the function r(x):

[tex]r(250) = 250\times(1000-2\times250) = $125,000[/tex]

So the maximum revenue the company can expect to earn is $125,000 if they sell their phones for $250 each.

B Players on the baseball team are generally taller than players on the basketball team.

D There is less variation in heights on the baseball team than on the basketball team.

C Players on the baseball team are generally the same height as players on the basketball team.

Answers

Answer: The answer is A) Players on the basketball team are generally taller than players on the baseball team. This is the most likely conclusion we can draw based on the information given.

Step-by-step explanation:

We know that the interquartile range (IQR) is the range of the middle 50% of the data. So for the basketball team, the heights of 50% of the players lie within the range of 73 ± 2.5 (since the IQR is 5). Similarly, for the baseball team, the heights of 50% of the players lie within the range of 72 ± 3 (since the IQR is 6).

Comparing the medians, we see that the basketball team has a median height of 73, while the baseball team has a median height of 72.

Based on this information, we can conclude that:

A) Players on the basketball team are generally taller than players on the baseball team - this is the most likely answer, as the median height of the basketball team is higher.

B) Players on the baseball team are generally taller than players on the basketball team - this is not supported by the given information.

D) There is less variation in heights on the baseball team than on the basketball team - we cannot determine this based on the given information.

C) Players on the baseball team are generally the same height as players on the basketball team - this is not supported by the given information.

Answer:

  (a, b) alternate interior angles at M and N, and at A and B are congruent

  (c) the triangles are congruent by SAS and by ASA (and MX = NX)

  (d) angles are no longer congruent, so the triangles are not congruent. The radii are given as congruent, but the chords cannot be shown congruent.

Step-by-step explanation:

Given same-size circles A and B, externally tangent to each other at X, each with chords MX and NX, you want to know what can be concluded if AM║BN, and what is unprovable if those segments are not parallel.

Same-size circles

The circles being the same size means all the radii are congruent. This is shown by the single hash marks in the attached diagram.

(a) Angles

Alternate interior angles where a transversal crosses parallel lines are congruent. If AM║BN, this means the angles marked with a single arc are congruent, and the angles marked with a double arc are congruent. These are the alternate interior angles at transversal MN and at transversal AB.

(b) Corresponding parts

If AM║BN, in addition to the given congruences, we also know ...

all radii are congruent — given in the problem statementangles M and N are congruent (see above)angles A and B are congruent (see above)the vertical angles at X are congruent to each other and to angles M and N (isosceles triangles) (AMBN is a parallelogram.)

(c) Congruent triangles

∆AMX ≅ ∆BNX by SAS or ASA (take your pick).

(d) Not parallel

If AM and BN are not parallel, MN is not a straight line through X, the angles at A and B are not congruent, and the angles at M and N are not congruent. (We assume segment AB still goes through X.)

__

Additional comment

Triangles MAX and NBX are isosceles, so their base angles are congruent. If X lies on MN, then AM and BN must be parallel, since the vertical angles at X will be congruent along with the other base angles at M and N. If AM and BN are not parallel, point X cannot lie on segment AB.

What equation relates the distance from Car A to the plane with x, y and z? Using implicit differentiation, solve for the appropriate derivative that answers the "how fast" question.

Answers

The distance between car A and the airplane is changing at a rate of 148.38 km/hr.

To better understand this answer, we can draw a sketch of the scenario and label the variables accordingly.

Let x represent the horizontal distance from P to the airplane, y the vertical distance from P to car A, and z the altitude of the airplane. The equation that relates the distance from car A to the plane can be written as:

[tex]d^2 = (x^2 + y^2 + z^2)[/tex]

We can use implicit differentiation to solve for the derivative of this equation with respect to time, which answers the “how fast” question. The derivative of the equation is:

x = 185t (horizontal distance from P to airplane)

y = 15 - 55t (vertical distance from P to car)

z = 2 (altitude of airplane)

Now we can substitute these expressions into our equation for the distance between the car and the airplane, and take the derivative with respect to time:

distance between car and airplane = sqrt((185t)^2 + (15 - 55t)^2 + 2^2)

d/dt(distance between car and airplane) = d/dt(sqrt((185t)^2 + (15 - 55t)^2 + 2^2))

= 1/2 * (185^2 * 2t + (15 - 55t)(-55)) / sqrt((185t)^2 + (15 - 55t)^2 + 2^2)

Evaluating this expression at t = 0 (the time when the car is at its closest point to the airplane), we get:

d/dt(distance between car and airplane) = 1/2 * (185^2 * 2(0) + (15 - 55(0))(-55)) / sqrt((185(0))^2 + (15 - 55(0))^2 + 2^2)

= 1/2 * (-825) / sqrt(15^2 + 2^2)

= -412.5 / sqrt (229)

The negative sign indicates that the distance between the car and the airplane is decreasing, as expected. Finally, we can take the absolute value of this expression to get the speed at which the distance is changing:

d/dt (distance between car and airplane)| = 412.5 / sqrt (229) ≈ 148.38 km/hr.

When the current in the loop is changed rapidly, the magnetic field it creates can change at a rate of 3.00 104 T/s. This rapidly changing magnetic field induces an electric current in a restricted region of the brain that can cause a finger to twitch, a bright spot to appear in the visual field, or a feeling of complete happiness to overwhelm a person. If the magnetic field changes at the previously mentioned rate over an area of 1.75 10-2 m2, what is the induced emf?

Answers

The induced emf in a region of the brain when a conducting loop is held near a person's head and the current in the loop is changed rapidly, is equal to -525 V.


The induced emf can be calculated using Faraday's law of electromagnetic induction, which states that the emf induced in a loop of wire is equal to the rate of change of magnetic flux through the loop.

The magnetic flux (Φ) is equal to the product of the magnetic field (B) and the area (A) through which it passes. Therefore, the induced emf (ε) is given by:

ε = -dΦ/dt ⇒ -B dA/dt.

Where the negative sign indicates that the emf is induced in a direction that opposes the change in magnetic flux.

In this problem, the magnetic field changes at a rate of 3.00 × 10^4 T/s over an area of 1.75 × 10^-2 m^2. Therefore, the induced emf is:
Plugging in our values, we get:
E = (-3.00 10^4 T/s)(1.75 10^(-2) m^2)/(1 s)
E = -525 V


Therefore, the induced emf, in this case, is -525 V. Here, the negative sign shows that the emf is induced in a direction that opposes the change in magnetic flux

My neighborhood is full of one-way streets. To drive from my house to the grocery store, I have to go 1 block south, then 1 block east, then 5 blocks north, then 2 blocks east. Each block is $\frac{1}{16}$ of a mile. How much shorter would my trip be if I could fly like a bird?

Express your answer in miles.

Answers

The trip would be shorter by $\frac{1}{4}-\frac{15}{16} = \frac{1}{16}$ of a mile  as per pythagorean theorem.

What is Pythagorean Theorem?

The Pythagorean theorem is a fundamental concept in geometry that describes the relationship between the sides of a right triangle. A right triangle is a triangle that has one angle that measures exactly 90 degrees, which is also known as a right angle.

In the given question, to find out how much shorter your trip would be if you could fly like a bird, we first need to find out the total distance of your current trip.

You go 1 block south, which is $\frac{1}{16}$ of a mile.

You then go 1 block east, which is also $\frac{1}{16}$ of a mile.

You then go 5 blocks north, which is $5\cdot\frac{1}{16} = \frac{5}{16}$ of a mile.

Finally, you go 2 blocks east, which is $2\cdot\frac{1}{16} = \frac{1}{8}$ of a mile.

So the total distance of your trip is $\frac{1}{16}+\frac{1}{16}+\frac{5}{16}+\frac{1}{8}=\frac{1}{4}$ of a mile.

If you could fly like a bird, you could go directly from your house to the grocery store, which we can assume is a straight line. Let's call the distance between your house and the grocery store "x".

Using the Pythagorean theorem, we can see that $x² = (\frac{1}{16})²+ (\frac{1}{8}+5\cdot\frac{1}{16})²$, which simplifies to $x² \frac{225}{256}$.

So the distance you would have to travel if you could fly like a bird is $\sqrt{\frac{225}{256}} = \frac{15}{16}$ of a mile.

Therefore, your trip would be shorter by

$\frac{1}{4}-\frac{15}{16} = \frac{1}{16}$ of a mile if you could fly like a bird.

7) A long piece of wire of length 90 cm is bent to form an equilateral triangle. What will be the length of each side of the triangle?​

Answers

Answer:

30cm

Step-by-step explanation:

Perimeter of an equilateral triangle = 3L

Mathematically we have;

P = 3L

Where P = perimeter of the triangle

L = Length

Therefore;

90 = 3L

Divide both side by 3

L = 30cm

Therefore, the length of each side of the triangle is 30cm.

A number is increased by 70% and the result is 42.5. What is the number?
A. 29.75
B. 27.5
C. 25
D. 17
E. 12.75

Answers

A. 29.75 because to find out 70% of 42.5 you do
42.5 x 0.7
which equals 29.75
x + 0.7x = 42.5
Simplifying the equation:
1.7x = 42.5
Dividing both sides by 1.7, we get:
x = 25

the answer is (C) 25.

The reaction of FeCl3 with 3 moles of NH4OH produces 4.2712 moles of Fe(OH)3 and 3 moles of NH4Cl. This can be determined by using the balanced chemical equation for the reaction:

FeCl3 + 3 NH4OH → Fe(OH)3 + 3 NH4Cl

Since the reaction produces 4.2712 moles of Fe(OH)3, then the amount of NH4Cl produced can be calculated using the mole ratio. The mole ratio of NH4Cl to Fe(OH)3 is 3:4.2712, which can be simplified to 3:4. Therefore, for every 4 moles of Fe(OH)3 produced, 3 moles of NH4Cl are also produced. Since 4.2712 moles of Fe(OH)3 are produced, then 3 x 4.2712 = 12.8136 moles of NH4Cl will also be produced.

Determine the domain D of the mapping f:x→x²+1, if R-(2, 5, 10) is the range and f defined on D. Hence Find the f-¹(5). If f(x)=0, find the values of x​

Answers

There are no values of x that satisfy the equation f(x) = 0.

what is a function?

A function is a mathematical concept that relates a set of inputs (known as the domain) to a set of outputs (known as the range), such that every input corresponds to exactly one output.

In other words, a function is a rule that assigns each element of the domain to a unique element of the range.

We are given that the mapping f(x) = x² + 1, and that the range of f is R - {2, 5, 10}.

To determine the domain of f, we need to consider what values of x will result in a valid output for f(x). Since f(x) is defined as x² + 1, we know that f(x) will always be greater than or equal to 1. Therefore, the domain of f is all real numbers, or D = R.

To find f⁻¹(5), we need to solve for x when f(x) = 5. That is, we need to solve the equation x² + 1 = 5. Rearranging, we get x² = 4, so x = ±2. Therefore, f⁻¹(5) = {-2, 2}.

Finally, to find the values of x when f(x) = 0, we need to solve the equation x² + 1 = 0. However, this equation has no real solutions, since the square of a real number is always non-negative.

Therefore, there are no values of x that satisfy the equation f(x) = 0.
