An imperfectly elastic ball is projected with the velocity [tex]\sqrt{gh}[/tex]  at an angle α with the horizontal, so that it strikes a vertical wall distant c from the point of projection, and returns to the point of projection.

Then, The Time of flight (T) =   [tex]\frac{2c}{ \sqrt{gh cosa } }[/tex]                

When a ball is projected with the velocity [tex]\sqrt{gh}[/tex]  at an angle α with the horizontal, it follows a parabolic path.

The ball will have a horizontal component of velocity (Vx) =  [tex]\sqrt{gh cosa}[/tex] , and a vertical component of velocity (Vy) = [tex]\sqrt{ghsina}[/tex] .

The ball will travel a horizontal distance equal to c before reaching the wall. The total time of flight (T) for the ball is equal to the time it takes the ball to reach the wall plus the time it takes for the ball to return to the point of projection.

The time it takes for the ball to reach the wall is equal  [tex]\frac{c}{vx}[/tex] , and the time it takes for the ball to return to the point of projection is also equal  [tex]\frac{c}{vx}[/tex].

Since the horizontal component of velocity (Vx) is equal to  [tex]\sqrt{gh cosa}[/tex] ,

the total time of flight (T) is equal to  [tex]\frac{2c}{ \sqrt{gh cosa } }[/tex] .

The correct question is:

An imperfectly elastic ball is projected with velocity √gh at an angle α with the horizontal, so that it strikes a vertical wall distant c from the point of projection, and returns to the point of projection. Then the time of flight is equal to?

Answer:

The answer is the last one

Step-by-step explanation:

Based on proportion, the amount of investment to have an annual interest of $150 at a 5% annual rate is $3,000.

The annual interest is the amount that is paid or received for accepting or giving credit.

The annual interest can be computed as the product of the annual percentage rate and the principal.

Where information for the interest rate and amount is available, the principal is the reciprocal of the interest and rate.

The annual interest rate = 5%

The annual interest (in dollars) = $150

Proportionately, $150 = 5%; therefore, 100%  of $150 = $3,000 ($150/5%)

The quadratic function graphed is defined as follows:

y = -x² + 6x - 8.

A quadratic function of roots x' and x'' is defined as follows:

y = a(x - x')(x - x'').

From the graph, the roots of the function are the x-intercepts, which are the values of x for which the graph crosses the x-axis, hence they are given as follows:

x = 2 and x = 4.

Hence:

y = a(x - 2)(x - 4)

y = a(x² - 6x + 8).

In which a is the leading coefficient.

The vertex is at (3,1), meaning that when x = 3, y = 1, hence the leading coefficient a is obtained as follows:

1 = a(3² - 6(3) + 8)

-a = 1

a = -1.

Hence the function is defined as follows:

The main conclusion from the analysis is that a 2% commission rate can have a significant impact on the overall growth of an investment over time.

Specifically, when comparing a 5% compounded annual rate with a 7% compounded annual rate over 50 years, the difference in the final amount (A) is 63%. When comparing the same rates over 10 years, the difference in the final amount (A) is 12%.

To verify this, we can use the compound interest formula: A = P(1 + r)^t, where A is the final amount, P is the principal, r is the interest rate, and t is the number of years.

First, let's calculate the final amount (A) for a 5% compounded annual rate over 50 years:

A = $10,000(1 + 0.05)^50 = $10,000(1.05)^50 = $10,000(2.65892) = $26,589.20

Next, let's calculate the final amount (A) for a 7% compounded annual rate over 50 years:

A = $10,000(1 + 0.07)^50 = $10,000(1.07)^50 = $10,000(3.98107) = $39,810.70

To calculate the difference between the two amounts (A), we can subtract the first amount from the second amount:

$39,810.70 - $26,589.20 = $13,221.50

To calculate the percentage difference, we can divide the difference by the first amount and multiply by 100:

($13,221.50 / $26,589.20) * 100 = 49.86%

Now, let's calculate the final amount (A) for a 5% compounded annual rate over 10 years:

A = $10,000(1 + 0.05)^10 = $10,000(1.05)^10 = $10,000(1.63) = $16,300

Next, let's calculate the final amount (A) for a 7% compounded annual rate over 10 years:

A = $10,000(1 + 0.07)^10 = $10,000(1.07)^10 = $10,000(1.9079) = $19,079

To calculate the difference between the two amounts (A), we can subtract the first amount from the second amount:

$19,079 - $16,300 = $2,779

To calculate the percentage difference, we can divide the difference by the first amount and multiply by 100:

($2,779 / $16,300) * 100 = 17%

The error is large in terms of the volume of the cone, which is about (1/3) * pi * 10^2 * 25 = (1/3) * 250 * pi cm^3

The volume of something determines how much space it takes up. Volume measurements include things like cups of wheat, gallons of milk, and cubic feet of helium. An object's weight serves as a proxy for its weightiness. Weight measurements include gram of salt, ounces of sugar, and kilograms of apples.

Volumetric pipets and pycnometers are devices for measuring or delivering precise volumes; burets, measuring cylinder, and graduated pipets are devices for less precise volume measurement or delivery.

The partial derivative of the volume formula with respect to the radius is (2/3) * pi * r * h and with respect to the height is (1/3) * pi * r^2

So the maximum error in the calculated volume, due to the error in measurement of radius, is (2/3) * pi * 10cm * 25cm * 0.1cm = (2/3)* 25 * pi cm^3

and the error in height is (1/3) * pi * 10cm^2 * 0.1cm = (1/3) * pi cm^3

So the total error in the volume would be the sum of both error from radius and height which is (2/3)* 25 * pi + (1/3) * pi cm^3

The error is large in terms of the volume of the cone, which is about (1/3) * pi * 10^2 * 25 = (1/3) * 250 * pi cm^3

The investment amount at each is $2000 at 7% interest and the $4000 remainder at 8%.

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

A total of $6000 was invested,

part of it at 7% interest and the remainder at 8%.

The total yearly interest amounted to $460.

That means,

we have the system of equations,

x + y = 6000    {equation 1}

0.07x + 0.08y = 460    {equation  2}

Substituting the value of y to the equation 2,

0.07x + 0.08(6000-x) = 460

480 - 0.01x = 460

-0.01x = 460 -480

0.01x = 20

x = 2000

And y = 4000

Therefore, 2000 in 1st account and 4000 in 2nd account.

Step-by-step explanation:

Given equation:

[tex]20\left(\dfrac{1}{2}\right)^{\frac{x}{3}} = 5[/tex]

Divide both sides by 20:

[tex]\implies\left(\dfrac{1}{2}\right)^{\frac{x}{3}} = \dfrac{20}{5}[/tex]

[tex]\implies\left(\dfrac{1}{2}\right)^{\frac{x}{3}} =\dfrac{1}{4}[/tex]

Subtract 4 from both sides:

[tex]\implies 2e^{2n-5} = 32[/tex]

Divide both sides by 2:

[tex]\implies e^{2n-5} = 16[/tex]

Take natural logs of both sides:

[tex]\implies \ln e^{2n-5} = \ln 16[/tex]

[tex]\textsf{Apply the power law}: \quad \ln x^n=n \ln x[/tex]

[tex]\implies (2n-5)\ln e = \ln 16[/tex]

Apply the law ln(e) = 1:

Rewrite 16 as 2⁴:

[tex]\implies 2n-5 = \ln 2^4[/tex]

[tex]\implies 2n-5 = 4\ln 2[/tex]

Add 5 to both sides:

[tex]\implies 2n = 4\ln 2+5[/tex]

Divide both sides by 2:

Given equation:

The value of the angles that are in the triangle will be 97°, 51° and 32°.

The first thing to note before solving the question is that the sum of the total angles that are in a triangle is 180°.

In this case, it should be noted that the angles that are given are represented by variables. Therefore, we'll add them together and equate them to 180°. This will be:

18x + 7 + 8x + 11 + 6x + 2 = 180

32x + 20 = 180

Collect the like terms

32x = 180 - 20

32x = 160

Divide

x = 160 / 32

x = 5

First angle = 18x + 7

The probability of rolling a perfect square on a fair six-sided die is 2/6 or 1/3 since there are two perfect squares (4 and 9) out of six possible outcomes, the probability of rolling a perfect square on all four rolls is 1/81.

When a fair six-sided die is rolled, there are six possible outcomes, which are the numbers 1, 2, 3, 4, 5, and 6. Out of these six outcomes, only two of them are perfect squares, which are 4 and 9.

Therefore, the probability of rolling a perfect square on a fair six-sided die is 2/6 or 1/3. Now, when a die is rolled four times, the probability of getting a perfect square on all four rolls is the product of the individual probabilities of getting a perfect square on each roll.

Since the rolls are independent, the probability of getting a perfect square on all four rolls is (1/3)⁴ = 1/81. Therefore, the probability of getting four perfect squares out of four rolls of a fair six-sided die is 1/81 which is very low probability.
