A student designs a container to prevent an egg from breaking when dropped from a height of 30 feet. Write a function that gives the height h (in feet) of the container after t seconds.

Answers

Answer 1

Answer:

As i understand, you put an egg inside a container, and then you drop it from 30ft above the ground.

Now, when the container is in the air, the only force acting on it will be the gravitational force (we can discard things like the air resistance, as we do not know the shape or volume of the container).

The gravitational acceleration is g = 32.2ft/s^2

Then the acceleration of the container will be:

A(t) = -32.2ft/s^2

For the velocity, we need to integrate over time to get:

V(t) = (-32.2ft/s^2)*t + v0

where v0 is the initial velocity, as the container is "dropped", the initial velocity is zero, then:

V(t) = (-32.2ft/s^2)*t

For the position, or height in this case, we integrate again over time, and get:

P(t) = (1/2)*(-32.2ft/s^2)*t^2 + p0

Where p0 is the initial height, 30 ft in this case.

Then the equation for the height, as a function of time, is:

P(t) = (-16.1ft/s^2)*t^2 + 30ft.

Where the fact that the container is made in such a way that an egg inside of it does not break (For example, made of a really dense and elastic material that can absorb all the energy of the impact), does not change anything in this equation, as the kinematics do not depend on that kind of properties.

Find the greatest common factor of 14 and 55

Answers

Answer: The factors of 14 are 14, 7, 2, 1.

             The factors of 55 are 55, 11, 5, 1.

The common factors of 14 and 55 are 1, intersecting the two sets above.

In the intersection factors of 14 factors of 55 the greatest element is 1.

Therefore, the greatest common factor of 14 and 55 is 1.

Step-by-step explanation:

The greatest common factor of 14 and 55 is 1.

To find the greatest common factor of 14 and 55.

First write the factor of 14.

14 × 1 = 14, 7 × 2 = 14, 2 × 7 = 14, 1 × 14 = 14.

Which are 14, 7, 2 and 1.

Now, write the factor of 55.

55 × 1 = 55, 11 × 5 = 55, 5 × 11 = 55, 1 × 55 = 55

Which are 55, 11, 5 and 1

Therefore, the common factor of 14 and 55 is 1.

Sarah would like to hire a clown for her daughter's birthday party. Clown A
is offering his services for an initial fee of $105 in addition to $9 per hour.
Clown B is offering her services for an initial $155 fee in addition to $6 per
hour. When will the two clowns charge the same amount of money? Use a
table to estimate the solution.

Answers

The two clowns charge the same amount of money at 16.66 hours.

What is Wages?

Payment for work based on hours worked (or sometimes per day or per amount of work done).

Here, let the duration of birthday party be x hours.

For Clown A,

Initial fee = $ 105

Additional charge = $ 9 per hour

Total amount of clown A = $ (9x + 105)   ...........(i)

For Clown B,

Initial fee = $ 155

Additional charge = $ 6 per hour

Total amount of clown B = $ (6x + 155)   ...........(i)

Now, according to question

9x + 105 = 6x + 155

9x - 6x = 155 - 105

3x = 50

x = 50/3

x = 16.66 hours

Thus, the two clowns charge the same amount of money at 16.66 hours.

Step 2: Solve for x

Distribute 2:                    2x - 8 < 12Isolate x term:                 2x < 20Isolate x:                          x < 10

A family eats out at a restaurant and the total for their meals is $73.89. They also pay sales tax of 5.8% and leave a tip for their server. If the family leaves a total of $93, which of the following might be a description of the service they received? a. They left a 10% tip, so the service was probably below average. b. They left a 15% tip, so the service was probably average. c. They left a 20% tip, so the service was probably above average. d. They left a 25% tip, so the service was probably outstanding.

Answers

Answer:

C.

Step-by-step explanation:

The sales tax is ≈ 12.74

The total of $93 - (12.74 + 73.89)  = 6.37

$6.37 is approximatley 20%

The description of the service they received is

They left a 20% tip, so the service was probably above average.

What is percentage?

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

let the amount of tax be x.

So, 100% of x = 73.89 x 5.8%

x = 428.562/100

x= 4.285

Now, the tip amount would be

= 93 - 73.89 4.28

= $14.83

Now, the amount of tip in percent is

73.89 / 100 = 14.83 / x

x = 14.83 /0.7389

x= 20.07

x= 20%

Rosa is closer to fossil exhibit than shelter house.

What is Distance Formula?

The two points in the cartesian plane P(a, b) and Q(c, d) then the distance between P and Q is

PQ = √c-a )² + (d-b)²

The distance from Rosa to shelter house

d= √(-2-1)² + (-4 +1)²

d =√9 + 9

d = √18

d = 4.24

Given: AE= 7 5/8cm, AB=BC, CD= 1/2cm, and DE is 3/8 more than AB. What is the length of DE?

Answers

Answer:

Length of DE = 2.90 (Approx)

Step-by-step explanation:

Given:

AE = 7[tex]\frac{5}{8}[/tex]cm = 61 / 8 cm = 7.625 cm

AB = BC

CD = 1/2 cm = 0.5 cm

DE is 3/8 more than AB

Find:

Length of DE

Computation:

Assume;

AB = BC = x

So,

DE = x + 3/8(x) = [11 / 8]x = [1.375]x cm

AE = AB + BC + CD + DE

7.625 = x + x + 0.5 + [1.375]x

7.125 = 3.375 x

x = 2.1111 (Approx)

Length of DE = [1.375][2.111]

Length of DE = 2.90 (Approx)
