Answer:

The height from ground, at which Jeb needs to hit the ball is 7.8 meters

Step-by-step explanation:

The given parameters are;

The distance away the tennis ball is hit = 20 meters;

The height of the tennis net = 0.3 m

The distance from the net the ball lands = 4 meters

The time the ball takes to land from the 0.3 m net height is given as follows;

t = √(h/(1/2×g)) = √(0.3/(1/2 × 9.8)) ≈ 0.2474

t ≈ 0.2474 seconds

The speed of the ball = Distance/Time = 4/0.2474 ≈ 16.166

The speed of the ball ≈ 16.166 m/s

The time it takes the ball to reach the net = 20/16.166 ≈ 1.24

The time it takes the ball to reach the net, tₓ ≈ 1.24 seconds

The height, hₓ the ball falls in 1.24 seconds is given as follows;

hₓ = 1/2·g·tₓ² = 1/2 × 9.8 × 1.24² = 7.5

The height, hₓ the ball falls in 1.24 seconds = 7.5 m

The height the ball falls in the time taken to reach the net from 20 meters = The height, hₓ the ball falls in 1.24 seconds

Therefore, the height at which Jeb needs to hit the ball = The height the ball falls in the time taken to reach the net from 20 meters + The height of the net = 7.5 m + 0.3 m = 7.8 m

The height at which Jeb needs to hit the ball = 7.8 m

If buying 3 beanies babies of same cost costs $d (all money that Jane had), then buying only one such beany baby would save Jane $2d/3

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get.

Thus, if 10 mangoes are there, and 2 people, then 10 ÷ 2 is the number of mangoes each person would get, which is 5.

Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.

Thus,  \(a \div b\)= a divided in b equal parts.

Also, we can write: \(a \div b = a \times \dfrac{1}{b}\)

(it is since a = a times 1 so \(a/b = 1 \times (a/b) = (1/b) \times a\) )

Given that:

To find:

The amount she'd save if she buy only one such beanie baby.

Amount that she'd save = Total amount she could've spent - Total price of one beanie baby

As we know, total amount she could've spent  = $d

Also, because of 3 beanie babies cosing equal, and total cost being $d,

the cost of each beanie baby is:

$d divided in 3 equal parts =  d/3 dollars

Thus, we get:

Amount that she'd save = Total amount she could've spent - Total price of one beanie baby

Amount that she'd save = \(d - \dfrac{d}{3} \: \rm dollars\)

We can write d = 3d/3 since dividing and multiplying a number by same non-zero number doesn't affect that number.

We do so, so that that both terms could get in fraction form with same denominator so that numerators could work directly.

\(d - \dfrac{d}{3} = \dfrac{3d}{3} - \dfrac{d}{3} = \dfrac{3d - d}{3} = \dfrac{2d}{3}\)

Thus, if buying 3 beanies babies of same cost costs $d (all money that Jane had), then buying only one such beany baby would save Jane $2d/3

5/365 years, or 0.014 years

Step-by-step explanation:

Just like any conversion of units, we just set up the starting amount and multiply it by the correct ratio:

    5 days (1 year/ 365 days) = 5/365 years = 0.014 years

You just need to make sure you choose the right ratio. In this case, I know that 1 year is 365 days, and I'm trying to cancel the days unit, therefore I put the year in the numerator and the days in the denominator.

I hope this helps :D

The confidence interval in "The 95% confidence interval for the mean, based on the given information, is (9.85, 11.32)" indicates that we are 95% confident that the true population mean falls within this range.

Interpreting the confidence interval, it means that if we were to take multiple samples from the same population and calculate the confidence intervals, approximately 95% of those intervals would contain the true population mean.

In this specific case, it suggests that we are 95% confident that the true mean lies between 9.85 and 11.32.

The confidence interval refers to the precision of our estimate, not the likelihood of the true mean falling within the specific interval calculated from a single sample.

the requried length and width of the pool can be given by the expression l = 38.5 - w.

Let's use algebra to solve this problem. Let's call the length of the pool "l" and the width of the pool "w". We know that the perimeter of a rectangle is given by:

Perimeter = 2l + 2w

2l + 2w = 77

l + w = 38.5

l = 38.5 - w

Thus, the requried length and width of the pool can be given by the expression l = 38.5 - w.

Answer:

In a regular 24-gon, each angle's measurement is 165 degrees.

Step-by-step explanation:

To determine the change in angular momentum (ΔL) of a cylinder from t = 0 to t = t0, a student can use the equation:

ΔL = I * Δω

where ΔL is the change in angular momentum, I is the moment of inertia of the cylinder, and Δω is the change in angular velocity.

To calculate Δω, the student needs to know the initial and final angular velocities, ω0 and ωt0, respectively. The change in angular velocity can be calculated as:

Δω = ωt0 - ω0

Once Δω is determined, the student can use the moment of inertia (I) of the cylinder to calculate ΔL using the equation mentioned earlier.

The moment of inertia (I) depends on the mass distribution and shape of the cylinder. For a solid cylinder rotating about its central axis, the moment of inertia is given by:

I = (1/2) * m * r^2

where m is the mass of the cylinder and r is the radius of the cylinder.

By substituting the known values for Δω and I into the equation ΔL = I * Δω, the student can calculate the change in angular momentum (ΔL) of the cylinder from t = 0 to t = t0.

It's important to note that this method assumes that no external torques act on the cylinder during the time interval. If there are external torques involved, the equation for ΔL would need to include those torques as well.

Answer:

Step-by-step explanation:

opposite sides are congruent

so  a + 19 = 33

a + 19 - 19 = 33 - 19

a = 14

consecutive angles are supplementary - they equal 180°

4r + 2r = 180

6r = 180

6r/6 = 180/6

r = 30

opposite angles are congruent

so 2r = z

if r = 30

2(30) = z

60 = z

However, we need to substitute a with s since that is the value we have calculated. Therefore, we get \(A(s) = (1/4)(5 + sqrt(5))s^2.\) This is the function notation that represents the area of a regular pentagon whose perimeter is 140 cm.

Let's consider that s be the length of a side of the regular pentagon.

The perimeter of the regular pentagon will be 5s. Therefore, we have the equation:5s = 140s = 28 cm

Also,

we have the formula for the area of a regular pentagon as:

\($A=\frac{1}{4}(5 +\sqrt{5})a^{2}$,\)

where a is the length of a side of the pentagon.

In order to represent the area of a regular pentagon whose perimeter is 140 cm, we need to substitute a with s, which we have already calculated.

Therefore, we have:\(A(s) = $\frac{1}{{4}(5 +\sqrt{5})s^{2}}$\)

Now, we have successfully used function notation (with the appropriate functions above) to represent the area of a regular pentagon whose perimeter is 140 cm.

The area of a regular pentagon can be represented using function notation (with the appropriate functions above). The first step is to calculate the length of a side of the regular pentagon by dividing the perimeter by 5, since there are 5 sides in a pentagon.

In this case, we are given that the perimeter is 140 cm, so we get 5s = 140, which simplifies to s = 28 cm. We can now use the formula for the area of a regular pentagon, which is\(A = (1/4)(5 + sqrt(5))a^2\), where a is the length of a side of the pentagon.

However, we need to substitute a with s since that is the value we have calculated. Therefore, we get\(A(s) = (1/4)(5 + sqrt(5))s^2.\) This is the function notation that represents the area of a regular pentagon whose perimeter is 140 cm.

The value of function f(1) = 1/16.

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input. A function is typically represented as y = f(x).

To find f(1), we substitute x = 1 into the given expression for f(x):

f(1) = 4(1/4)⁽¹⁺²⁾ = 4(1/4)³ = 4(1/64) = 1/16

Answer:

3b/2 + 3

Step-by-step explanation:

The formula to calculate perimeter of rectangle is 2l + 2w

The length is half the width so length is 1/2 (b/2 +1), which when simplified is b/4 + 1/2

Using the formula to calculate perimeter you can substitute and calculate

p= 2l + 2w

p= 2(b/4 + 1/2) + 2(b/2 + 1)

p= 2b/4 +2/2 + 2b/2 +2

p= 1/2b + 1 + b + 2

p= 3/2b + 3

Simplified it's 3b/2 +3

By solving differential equation for \(du/dt = e^5u + 3t.\) The u =\((-1/5) ln[25t + e^{-5u} - 26].\)

We have to separate variables first:

\(du/e^5u = dt + 3t/e^{5} u du\)

Now, we will integrate sides to their variables:

∫ du/\(e^{5u}\)= ∫ (dt + 3t/\(e^{5u}\)) du

Using substitution:

let w = 5u, then du = dw/5:

1/5 ∫ dw = \(e^{-w}\)∫ (dt + 3t/\(e^w\) (du/5)

Integrating both sides:

-1/5 \(e^{-w}\)= t + (1/25) \(e^{-w}\) + C

Substituting back w = 5u:

-1/5 \(e^{-5u}\)= t + (1/25) \(e^{-5u}\) + C

Using initial condition, u(0) = 5:

-1/5 \(e^{-25}\) = 0 + (1/25) \(e^{-25}\) + C

C = -26/25

The solution to differential equation with initial condition is:

-1/5 \(e^{-5u}\) = t + (1/25) \(e^{-5u}\)- 26/25

When we solve for u, we have:

u = (-1/5) ln[25t + \(e^{-5u}\)- 26].
