Justin Bieber is thrown horizontally at 10.0m/s from the top of a cliff 122.5 m high.
How long does it take to reach the ground?
What is the horizontal displacement?
What is Justin's final velocity?

Answers

Answer:

Step-by-step explanation:

How long it takes to reach the ground is a y-dimension thing, and horizontal displacement is an x-dimension thing.  So let's set up a table with the info we have in each dimension:

                           x                             y

V₀                     10.0 m/s               10.0 m/s

Δx                        ?                       -122.5 m

a                       0 m/s/s                -9.8 m/s/s

v                       10.0 m/s                    ?

t                           ?                             ?

That seems like an awful lot of question marks, doesn't it?

The first question asks us for the time, t, it takes for the pathetic and greatly disliked Justin Bieber to hit the ground.  We will use the equation:

Δx = V₀t + 1/2at²

Filling in our values using the y-dimension stuff only:

[tex]-122.5 = 10.0t+\frac{1}{2}(-9.8)t^2[/tex] which simplifies to

[tex]-122.5=10.0t-4.9t^2[/tex]

Hmmm...this is beginning to resemble a parabolic equation you probably already studied in Algebra 2!

We can solve for t by getting everything on one side and setting the equation equal to 0.  We set it equal to 0 since the height on the ground is 0:

[tex]-4.9t^2+10.0t+122.5=0[/tex]

When you factor that for the 2 values of t, you get

t = -4.1 and 6.1

Of course, since time can't EVER be negative, we use a t value of 6.1.  That's how long it takes to hit the ground.  That t value can now be filled into the t values in our table above.  We need that t value for the next part that asks us the horizontal displacement, Δx.  This is x-dimension stuff now.  Using the same equation:

Δx =[tex]10.0(6.1)+\frac{1}{2}(0)(6.1)^2[/tex]

Of course since the acceleration in the x-dimension is always 0, the whole portion of the equation after the equals sign is eliminated, leaving us with

Δx = 10.0(6.1)

Δx = 61 m

Poor Justin, upon his demise, hits the ground.  Therefore, his final velocity is 0, since his body met the ground and stopped dead.

The rectangle below has an area of 81- x^2 square meters and a width of 9 - x meters

Answers

The length of a rectangle with an area of 81 - x² square meters and a width of 9 - x meters is (81 - x²) / (9 - x) .

To find the expression that represents the length of the rectangle, we need to use the formula for the area of a rectangle, which is:

Area = Length × Width

Given that the area of the rectangle is 81 - x² square meters and the width is 9 - x meters, we can set up the equation as:

81 - x² = Length × (9 - x)

To isolate the Length, we divide both sides of the equation by the Width (9 - x):

Length = (81 - x²) / (9 - x)

Therefore, the expression that represents the length of the rectangle is:

Length = (81 - x²) / (9 - x)

What is the area of a triangle (picture provided)

Answers

Answer:

C

Step-by-step explanation:

Use the Heron's formula for the area of the triangle:

[tex]A=\sqrt{p(p-a)(p-b)(p-c)},[/tex]

where a, b, c are lengths of triangle's sides and [tex]p=\dfrac{a+b+c}{2}.[/tex]

Since [tex]a=2,\ b=7,\ c=8,[/tex] then

[tex]p=\dfrac{2+7+8}{2}=8.5.[/tex]

Hence,

[tex]A=\sqrt{8.5(8.5-2)(8.5-7)(8.5-8)}=\sqrt{8.5\cdot 6.5\cdot 1.5\cdot 0.5}=\\ \\=\sqrt{41.4375}\approx 6.4\ un^2.[/tex]

Answer:

Area Δ = 6.4 units² ⇒ the answer is (c)

Step-by-step explanation:

* Use the formula of the area:

∵ Area of the triangle = 1/2 (a)(b) sin(C)

∵ We have the length of the 3 sides

∴ Use cos Rule to find the angle C

∵ cos(C) = (a² + b² - c²)/2ab

∵ a = 2 , b = 7 , c = 8

∴ cos(C) = (2² + 7² - 8²)/2(2)(7) = 4 + 49 - 64/28 = -11/28

∴ m∠C = 113.1°

∴ Area Δ = (1/2)(2)(7)sin(113.1) = 6.4 units²

Let's take first number as in the red cube and the second number is in blue cube.

We get x = -2 for the following outcomes

(1, 3), (2, 4), (3, 5), and (4, 6).  which is 4 favorable outcomes.

We get x = -1,  for the following outcomes:

(1, 2), (2, 3), (3, 4), (4, 5), and (5, 6).  which is 5 favorable outcomes

We get x = 0, when (1, 1) (2, 2)(3, 3)(4, 4) (5, 5),(6, 6) which is 6

We get x = 1, when (2, 1), (3, 2) (4, 3) (5, 4) (6, 5), which is 5.

The number of favorable outcomes=  4 + 5 + 6 + 5 = 20

The number of possible outcomes = 36 (when we toss the two dices, the possible number of outcomes is 36)

The required probability  P(−2≤X≤1) = The total number of favorable outcomes / the total number of possible outcomes

= 20/36

P(−2≤X≤1) = 5/9.

Answers

Answer:

$131,450

$9,500

$9.44

$12.44

$4,590

$107,600

$-1,620

Step-by-step explanation:

Let's take it one at a time. To find the fixed costs per unit, we use the formula.

[tex]FixedCostPerUnit=\dfrac{FixedCosts}{ForecastUnitSales}[/tex]

So our variables are.

Fixed Costs = $85,000

Forecast = 11,000 units

Now we compute.

[tex]FixedCostPerUnit=\dfrac{85,000}{11,000}[/tex]

[tex]FixedCostPerUnit=$7.73[/tex]

Now for the Gross Sales, we simply take the selling price per unit and multiply it to the forecast unit sales.

GrossSales = Selling Price x Forecast Unit Sales

GrossSales = $11.95 x 11,000

GrossSales = $131,450

To compute for the possible net profit, we use the formula:

[tex]NetProfit=(SellingPrice-TotalCostPerUnit)*ForecastUnitSales[/tex]

SellingPrice = $12.45

TotalCostPerUnit = $11.50

ForecastUnitSales = 10,000

NetProfit = (12.45 - 11.50) x 10,000

NetProfit = 0.95 x 10,000

NetProfit = $9,500

[tex]FixedCostPerUnit=\dfrac{FixedCosts}{ForecastUnitSales}[/tex]

FixedCosts = $85,000

ForecastUnitSales = 9,000

[tex]FixedCostPerUnit=\dfrac{85,000}{9,000}[/tex]

FixedCostPerUnit = $9.44

Now that we have our Fixed Cost Per Unit we simply add our Variable Cost to get the Total Cost Per Unit.

TotalCostPerUnit = FixedCostPerUnit + VariableCost

TotalCostPerUnit = $9.44 + $3.00

TotalCostPerUnit = $12.44

Now for the Net Profit.

[tex]NetProfit=(SellingPrice-TotalCostPerUnit)*ForecastUnitSales[/tex]

SellingPrice = $12.95

TotalCostPerUnit = $12.44

ForecastUnitSales = 9,000

NetProfit = (12.95 - 12.44) x 9,000

NetProfit = 0.51 x 9,000

NetProfit = $4,590

Now we're looking for Gross Sales again, so we use:

GrossSales = Selling Price x Forecast Unit Sales

GrossSales = $13.45 x 8,000

GrossSales = $107,600

[tex]NetProfit=(SellingPrice-TotalCostPerUnit)*ForecastUnitSales[/tex]

SellingPrice = $13.45

TotalCostPerUnit = $13.63

ForecastUnitSales = 8,000

NetProfit = (13.45 - 13.63) x 8,000

NetProfit = -0.18 x 9,000

NetProfit = $-1,620

So we can see that we have a profit loss at 8,000 units and a selling price of $13.45

Eleni bought 3 packs of crayons. She then found 3 crayons in her desk Eleni now has 24 crayons. How many crayons were in each pack? Explain how you solved the problem.

Answers

Answer:

7 crayons in each pack

Step-by-step explanation:

1. subtract the 3 found crayons from the total (24)

    24-3 = 21

2. divide 21 by 3 packs

   21/3 = 7

Final answer:

Eleni ended up with 24 crayons after buying 3 packs and finding 3 more in her desk. To find the number of crayons per pack, we subtract the 3 found crayons from the total, giving us 21 crayons that came from the packs. Dividing 21 by the 3 packs she bought, we get 7 crayons per pack.

Explanation:

The subject of this question is mathematics, specifically an arithmetic problem that involves addition and division. Eleni bought 3 packs of crayons and found 3 more crayons in her desk, which resulted in her having a total of 24 crayons. To solve for the number of crayons in each pack, we start by subtracting the 3 crayons she found from the total, leaving us with 21 crayons that came from the packs. We then divide this number by the number of packs to find out how many crayons were in each pack.

Here's a step-by-step solution:

Start with the total number of crayons Eleni has after finding the extra ones in her desk: 24 crayons.

Subtract the 3 crayons found in her desk: 24 crayons - 3 crayons = 21 crayons.

Divide the resulting number of crayons by the number of packs she bought: 21 crayons \/ 3 packs = 7 crayons per pack.

Therefore, there were 7 crayons in each pack.

In your own words, without providing the formulas, describe the difference between simple interest and compound interest. Which type of interest earns money more quickly?


Answers

Simple interest is when interest is paid once on money.  Compound interest is paid periodically.  Compound interest earns money more quickly because you are actually earning interest on interest.  For example, if interest is compounded monthly you will received interest on your principal in January, and then in February you will receive interest on the principal and on the interest that was earned in January.

Sample Response: Simple interest is applied only to principal investment amounts each year. Compound interest applies to principal investment amounts, but also applies to any previously earned interest. Compound interest earns money more quickly.

Jamal will slice a right circular cylinder into two congruent pieces. Which two dimensional plane sections could result from the slice Jamal makes?

Answers

Answer:

An ellipse and a rectangle.

Step-by-step explanation:

If Jamal cuts the right circular cylinder anywhere but its extremities, the resulting shapes on both pieces will be an ellipse.  

If he cuts precisely in a perpendicular way in relation to the ends, he will then form two new right circular cylinders, then the ellipses obtained would be circles.

If Jamal cuts the right circular cylinder lengthwise, going from one end to the other, even if it's not perpendicular to the base, he will obtain a rectangular shape.

A two-dimensional plane section that could result from slicing a right circular cylinder into two congruent pieces is a circle.

When a right circular cylinder is sliced at the center of the vertical height, the surface of either section is a circle.

However, when a right circular cylinder is sliced at the center of the circular surface, the surface of either section is a rectangle.

Hence, the resulting shapes are circles and rectangles

If you invest $1200 at an interest rate of 1.3% compounded continuously,

a) How much will you have in 5 years?

b) How long will it take for your investment to double?

Answers

Answer:

$1280.59

53 years

Step-by-step explanation:

To find how much we will get in 5 years, we use the formula:

[tex]A=Pe^{rt}[/tex]

P = $1200

r = 1.3% or 0.013

t = 5

Now that we have our values, let's plug them into the formula.

[tex]A=1200e^{0.013(5)}[/tex]

[tex]A=1200e^{0.065}[/tex]

[tex]A=1280.59[/tex]

We will have $1280.59 after 5 years.

Now to find how long it will take for our investment to double.

t = ln(A/P)/r

A = 2400

P = 1200

r = 1.3 or 0.013

Let's plug it in.

t = ln(2400/1200)/0.013

t = ln(2)/0.013

t = 53.32 or 53 years

A piece of wire 24 m long is cut into two pieces. One piece is bent into a square and the other is bent into a circle.

Incorrect: Your answer is incorrect. m (b) How much wire should be used for the square in order to minimize the total area?

Answers

Final answer:

The solution to this problem involves using calculus to model the total area as a function of the lengths of the wire used for the square and the circle. However, without further context or information, a concrete answer cannot be provided.

Explanation:

In this given case, you have a wire of length 24m that needs to be bent into two shapes - a square and a circle - and we need to know how much wire should be used for the square to maximize or minimize total area. The problem involves concept of both geometry and calculus.

To find the solution we must determine the lengths for the square and the circle that will maximize or minimize the total area. But the concept of area maximization and minimization comes from calculus, especially derivative application. Specifically, to find the maximum or minimum area, we would model the total area as a function of lengths and use first derivative to find where the area is maximized and minimized. Unfortunately, without more context or information, we cannot provide an accurate answer to this question.

Learn more about Calculus and Geometry here:

https://brainly.com/question/13788254

#SPJ12

Final answer:

To maximize the total area, use 192 / (2π + 8) units of wire for the square and 24 - 192 / (2π + 8) units of wire for the circle. To minimize the total area, follow the same wire lengths.

Explanation:

To maximize the total area, we need to find the lengths of the wire that will create squares and circles with the largest possible areas. Let's start with part (a).

Part (a)

Let the length of the wire used for the square be x. Then the length of the wire used for the circle would be 24 - x. The perimeter of the square is 4x, so the side length of the square is x/4. The circumference of the circle is 2πr, where r is the radius. Since the wire used for the circle is 24 - x, we have 2πr = 24 - x. Solving for r, we get r = (24 - x) / (2π).

The area of the square is (x/4)^2 = x^2/16. The area of the circle is πr^2 = π((24 - x) / (2π))^2 = (24 - x)^2 / (4π). The total area is the sum of the areas of the square and the circle, so we need to maximize (x^2/16) + (24 - x)^2 / (4π).

Let's find the derivative of this expression with respect to x, set it equal to 0, and solve for x:

(1/8)x - (24 - x) / (2π) = 0

Simplifying, we get (1/8)x = (24 - x) / (2π)

Multiplying both sides by 8 and 2π, we have 2πx = 8(24 - x)

Expanding, we get 2πx = 192 - 8x

Bringing like terms to one side, we have 2πx + 8x = 192

Combining like terms, we get (2π + 8)x = 192

Dividing both sides by (2π + 8), we have x = 192 / (2π + 8)

Now that we have the value of x, we can calculate the lengths of the wire used for the square and the circle. The length of the wire used for the square is x, which is equal to 192 / (2π + 8). The length of the wire used for the circle is 24 - x, which is equal to 24 - 192 / (2π + 8).

So, the solution for part (a) is to use 192 / (2π + 8) units of wire for the square and 24 - 192 / (2π + 8) units of wire for the circle in order to maximize the total area.

Part (b)

To minimize the total area, we follow a similar approach. The area of the square is x^2/16 and the area of the circle is (24 - x)^2 / (4π). We want to minimize (x^2/16) + (24 - x)^2 / (4π).

Again, let's find the derivative of this expression with respect to x, set it equal to 0, and solve for x:

(1/8)x - (24 - x) / (2π) = 0

Expanding and rearranging, we get (2π + 8)x = 192

Dividing both sides by (2π + 8), we have x = 192 / (2π + 8)

As in part (a), the length of the wire used for the square is x, which is equal to 192 / (2π + 8), and the length of the wire used for the circle is 24 - x, which is equal to 24 - 192 / (2π + 8).

Therefore, the solution for part (b) is to use 192 / (2π + 8) units of wire for the square and 24 - 192 / (2π + 8) units of wire for the circle in order to minimize the total area.
