Answer:

Daniel has to wait around 5.24 years to withdraw the money.

Step-by-step explanation:

We are given that Daniel wants to open an account to purchase a new computer. He was able to put $750 into an account that pays him 8.5% interest. The cost of the computer he wants is $1,150.00.

Let the Principal sum of money be represented by 'P'.

The rate of interest be represented by 'R'.

The time period be represented by 'T'.

The final amount of money be represented by 'A'.

Assuming the interest given is compound interest.

So, the formula for calculating the amount of money is given by;

                          [tex]\text{A} = \text{P} \times (1-\text{R})^{\text{T}}[/tex]

Here, A = $1,150, P = $750, R = 8.5% and let the time he have to wait to withdraw the money be 'n'.

So, putting these values in the above formula we get;

[tex]\text{A} = \text{P} \times (1+\text{R})^{\text{T}}[/tex]

[tex]\text{\$1,150} = \text{750} \times (1+\text{0.085})^{\text{n}}[/tex]

[tex](1+\text{0.085})^{\text{n}} = \frac{\$1,150}{\$750}[/tex]

[tex](1+\text{0.085})^{\text{n}} = 1.533[/tex]

Taking log on both sides;

[tex]\text{n} \times ln(1+\text{0.085}) = ln(1.533)[/tex]

[tex]n = \frac{ ln(1.533)}{ ln(1.085)}[/tex]

n = 5.24 years

Hence, he has to wait around 5.24 years to withdraw the money.

Answer:

The temperature at 10 pm was -1 degrees and the arrows helped you understand when the temperature increased and decreased.

Step-by-step explanation:

At 8 am, we know that the temperature is -3 degrees, or 3 degrees below zero. By 1 pm, the temperature has risen by 14 degrees and is now 11 degrees. We know this because -3+14=11. Now by 10 pm, the temperature has dropped 12 degrees which means that it's -1 degrees. (11-12=-1) The plot points would be all of the temperatures, or -3, 11, and -1. The arrows you need to draw are from -3 to 11 (an increase) and from 11 to -1 (a decrease). Drawing the arrows this way represents the temperature at different times and how it changed over time.

Answer:

419.25

Step-by-step explanation:

The calculation of the cost of materials for the cheapest such container is shown below:-

We assume

Width = x

Length = 2x

Height = h

where, length = [tex]2 \times width[/tex]

Base area = lb

= [tex]2x^2[/tex]

Side area = 2lh + 2bh

= 2(2x)h + 2(x)h

= 4xh + 2xh

Volume = 24 which is lbh = 24

[tex]h = \frac{24}{2x^2} \\\\ h = \frac{12}{x^2}[/tex]

Now, cost is

[tex]= 13(2x^2) + 9(4xh + 2xh)\\\\ = 13(2x^2) + 9(4x + 2x)\times \frac{12}{x^2} \\\\ = 26x^2 + \frac{648}{x}[/tex]

now we have to minimize C(x)

So, we need to compute the C'(x)

[tex]= 52x - \frac{648}{x^2}[/tex]

C"(x)  [tex]= 52x - \frac{1,296}{x^3}[/tex]

now for the critical points, we will solve the equation C'(x) = 0

[tex]= 52x - \frac{648}{x^2} = 0\\\\ x = \frac{648}{52}^{\frac{1}{3}}[/tex]

[tex]C" = ((\frac{648}{52} ^{\frac{1}{3} } = 52 + \frac{1296}{(\frac{648}{52})^\frac{1}{3} )^3}\\\\ = 52 + \frac{1296}{\frac{648}{52} } >0[/tex]

So, x is a point of minima that is

= [tex](\frac{648}{52} )^\frac{1}{3}[/tex]

Now, Base material cost is

[tex]= 13(2x^2)\\\\ = 26(\frac{648}{52} )^\frac{2}{3}[/tex]

= 139.75

Side material cost is

[tex]= \frac{648}{x} \\\\ = \frac{648}{(\frac{648}{52})^\frac{1}{3} }[/tex]

= 279.50

and finally

Total cost is

= 139.75 + 279.50

= 419.25

The cost of the side material is $279.50, the cost of the base material is $139.75 and the total cost is $419.25 and this can be determined by using the arithmetic operations.

Given :

Let the width of the rectangular storage container be 'x' then according to the given data the length is '2x' and let the height of the container be 'h'.

The base area of the rectangular storage container is given by:

Base Area = [tex]2x^2[/tex]   ----- (1)

The side area of the rectangular storage container is given by:

Side Area = 2(2x)h + 2xh

                 = 6xh    ---- (2)

Now, the volume of the rectangular storage container is given by:

Volume = lbh

Put the values of known terms in the above equation.

24 = [tex]2x^2h[/tex]

[tex]h = \dfrac{12}{x^2}[/tex]

Now, the cost is given by:

[tex]\rm C(x)=13(2x^2)+9(6xh)[/tex]

[tex]\rm C(x)= 26x^2 + \dfrac{648}{x}[/tex]

Now, to minimize C(x) differentiate the C(x) with respect to x.

[tex]\rm C'(x)=52x -\dfrac{648}{x^2}[/tex]   ---- (3)

Now, equate the above equation to zero.

[tex]0 = 52x =\dfrac{648}{x^2}[/tex]

[tex]x = \sqrt[3]{\dfrac{648}{52}}[/tex]

Now, differentiate equation (3) with respect to x.

[tex]\rm C"(x) = 52+\dfrac{1296}{x^3}[/tex]

Now, put the value of x in the above equation.

[tex]\rm C"(x) = 52+\dfrac{1296}{\dfrac{648}{52}}[/tex]

[tex]\rm C"(x) = 52+104[/tex]

[tex]\rm C"(x) = 156 > 0[/tex]

Therefore, 'x' is the point of minima.

Now, the cost of the base material is:

[tex]= 13\times 2 \times (\dfrac{648}{52})^\frac{2}{3}[/tex]

= $139.75

Now, the cost of the side material is:

[tex]=\dfrac{648}{\sqrt[3]{\dfrac{648}{52}} }[/tex]

= $279.50

Therefore, the total cost is given by:

= 139.75 + 279.50

= $419.25

Given that :-

To Find :-

Solution :-

The fist expression x + y < 5 states that sum of x and y could be any rational number less than 5 .

And the second expression 3 < x < 5 states that value of x could be any rational number between 3 and 5.

Let's check which option suits best.

Is it possible to have value of 8/3 by y ?

→ x + 8/3 < 5

→ x < 5 - 8/3

→ x = 7/3

7/3 is a rational number . So y as 8/3 is possible value.

→ 7/3 = 2.33

But value of x should be greater than 3 .

So option A is wrong.

Is it possible to have value 2 by y ?

→ x +2 < 5

→ x < 5-2

→ x < 3 .

But value of X should be greater than 3.

So option B is also incorrect.

Is it possible to have value 0 by y?

→ x +0 <5

→ x < 5

It also fullfill 2nd expression that X should have value less than 5 and greater than 3.

So option C is valid .

The right triangles are similar, allowing us to form the proportion below

BD/AD = AD/DC

5/AD = AD/9 .... substitution

5*9 = (AD)*(AD) .... cross multiply

45 = (AD)^2

(AD)^2 = 45

AD = sqrt(45) ... apply square root

We could simplify but your teacher has decided not to. If you want to simplify, then

AD = sqrt(45)

AD = sqrt(9*5)

AD = sqrt(9)*sqrt(5)

AD = 3*sqrt(5)

--------

Segment AD is the geometric mean of BD and DC.

AD = sqrt(BD*DC)

which is the result of solving BD/AD = AD/DC for AD

So,

AD = sqrt(BD*DC)

AD = sqrt(5*9)

AD = sqrt(45)

Answer:

Set the area equal to x2, solve for x, and then multiply the value of x by 4.

Step-by-step explanation:

The area of the picture is given by

A = s^2 where s is the side length

Let the side length be x

A = x^2

Take the square root of each side

sqrt(A) = sqrt(x^2)

x = sqrt(A)

We want to find the perimeter since we are framing the border

P = 4s since the picture is a square

P = 4 * x

Answer:

B.

Step-by-step explanation:

Let's let x represent the side length of the square.

Since the picture is a square, all the lengths are the same. Moreover, the area of the square is x times x or x squared. Thus:

[tex]A=x^2[/tex]

The amount of framing Sachiko needs is represented by the perimeter of the square. The perimeter of a square is determined by the formula:

[tex]P=4x[/tex]

Now, if Sachiko knows the area and she wants to find the perimeter, she can do the following:

First, the area is equal to x^2. So, she should first just find the length itself. So her first step should be to set the area equal to x^2 and then solve for x.

Then, when she has found her length, she just need to multiply it by 4 to get the perimeter or the amount of framing she needs.

Thus, the answer is choice B.

Step-by-step explanation:

Nesta questão, estamos interessados ​​em calcular a distância percorrida se um jogador correr a uma velocidade de 43,2 km / h por 3 segundos.

Matematicamente; a distância percorrida = velocidade * tempo

O problema que temos aqui é que nossas unidades não são consistentes.

A melhor maneira de fazer isso é ter unidades consistentes em metros por segundos e segundos, pois nossa resposta está em metros.

Portanto, a conversão que precisamos fazer aqui é converter 43,2 km / h em metros por segundo Matematicamente, sabemos que existem 1000 m em um quilômetro.

Da mesma forma, uma vez que 60 segundos fazem um minuto e 60 minutos fazem uma hora, o número de segundos em uma hora é 60 * 60 = 3.600 segundos

Assim, convertendo 43,2 km / h em m / s, temos; (43,2 * 1000) / 3600 = 12 m / s

Portanto, a distância percorrida em metros seria agora; velocidade em m / s * tempo em segundos = 12 m / s * 3 segundos = 36 m
