Final answer:

The largest volume among the rectangular prisms is 75 cm³, corresponding to the prism with dimensions l = 5 cm, w = 3 cm, and h = 5 cm.

Explanation:

To determine which rectangular prism has the largest volume, we must calculate the volume of each given prism. The volume (V) of a rectangular prism is calculated by multiplying its length (l), width (w), and height (h): V = l × w × h.

For the first prism, V = 4 cm × 5 cm × 3 cm = 60 cm³

For the second prism, V = 6 cm × 3 cm × 3 cm = 54 cm³

For the third prism, V = 2 cm × 6 cm × 6 cm = 72 cm³

For the fourth prism, V = 5 cm × 3 cm × 5 cm = 75 cm³

By comparing the volumes calculated, the prism with dimensions w = 3 cm, l = 5 cm, and h = 5 cm has the largest volume, which is 75 cm³.

Answer:

[tex]t \approx 750550.12\,yr[/tex]

Step-by-step explanation:

The time constant of the isotope is:

[tex]\tau = \frac{1.3\times 10^{9}\,yr}{\ln 2}[/tex]

[tex]\tau \approx 1.876 \times 10^{9}\,yr[/tex]

The decay of the isotope is described by the following model:

[tex]\frac{m}{m_{o}} = e^{-\frac{t}{\tau} }[/tex]

Now, the time is cleared in the equation:

[tex]t = -\tau \cdot \ln \frac{m}{m_{o}}[/tex]

[tex]t = - (1.876\times 10^{9}\,yr)\cdot \ln 0.9996[/tex]

[tex]t \approx 750550.12\,yr[/tex]

The rock from Maui with 99.96% of its parent K-40 remaining is significantly younger than 1.3 billion years, the half-life of K-40. The precise age calculation would yield a time much less than the half-life, indicating the rock's relative youth.

The age of a rock that has 99.96% of its parent K-40 remaining can be calculated using the half-life of K-40, which is 1.3 billion years. Since such a small percentage (0.04%) of K-40 has decayed to form Ar-40, the rock sample from Maui is very young relative to the half-life of K-40. We can estimate the age of the rock by using the concept of half-lives in radioactive decay.

The formula for radioactive decay is: N(t) = N0 (1/2)^(t/T), where N(t) is the amount of the parent isotope remaining, N0 is the initial amount of the parent isotope, t is the time that has elapsed, and T is the half-life of the isotope.

In the case of Maui's rock, with N(t)/N0 being approximately 0.9996 (or 99.96/100), we can set up the equation as follows: 0.9996 = (1/2)^(t/1.3 billion years). Solving for t gives an age that is much less than 1.3 billion years, indicating that the rock is relatively young and has experienced only a fraction of a half-life period.

However, because the amount of decay is so small, it would fall within the uncertainties of practical measurement and thus would only give us an approximation that the age of the rock is significantly less than one half-life, or markedly younger than 1.3 billion years.

Answer:

h  = 9 units of length

Step-by-step explanation:

Volume of a circular right cone is:

V(c)  = (1/3)*Area of the circular base * h

Where h is the height of the cone, then

V(c)  =  (1/3) * π * r² * h

And  we have that  V(c) = 108*π

Then:

108 * π  =  (1/3) * π * r² * h                  (1)

We know diameter of the circular base is 12 units, according to that

r =  d/2     ⇒  r = 12/2     r = 6 units

Then:

108 * π  [ cubic units ]  =  (1/3) * π * (6)² * h  [square units] [ units of length]

When simplifying we have to take into account that in order to keep last equation h needs to have units of length  

Therefore:

108  =  (1/3) * 36 * h

h = ( 108* 3 )/ 36

h  = 9 units of length

Answer:

5.5lb of strawberries cost $10.78

Step-by-step explanation:

We can use ratios to solve this problem.

 lb : $$$

0.5 : 0.98

  5 : 9.8

5.5 : 10.78

5.5lb of strawberries cost $10.78

You can also divide 5.5 by 0.5 (pounds) and multiply the quotient by how much a 0.5 pound of strawberries cost.

To find the total cost of 5.5 pounds of strawberries, determine the cost of one pound by doubling the cost for a half-pound. Then multiply the cost of one pound by the quantity of pounds purchased to get the total cost, which is $10.78.

The question asks us to calculate the total cost of 5.5 pounds of strawberries when given the price for a half-pound. The first step is to determine the cost of one pound of strawberries by doubling the cost of the half-pound.

If a 1/2 pound of strawberries costs $0.98, then one pound would cost $1.96 (since 0.98 x 2 = 1.96).

Next, to find out how much 5.5 pounds would cost, multiply the cost of one pound by 5.5:

5.5 pounds of strawberries x $1.96 per pound = $10.78.

Therefore, if you bought 5.5 pounds of strawberries, you would have spent $10.78.

Answer:

A

Step-by-step explanation:

Because think about it if there’s no one working in a business then there’s no work and no one gets paid in their business that’s how technology affects places where people work.

The answer is option C - More people are working from a remote location rather than an office building.

Technology has enabled a significant shift in the way people work, allowing many to perform their tasks remotely from locations outside of traditional office settings. With advancements in communication technology, internet connectivity, and collaboration tools, individuals can now work from virtually anywhere with an Internet connection. This trend towards remote work has been accelerated by factors such as the COVID-19 pandemic, which necessitated remote work arrangements for many organizations.

As a result, more people are opting to work from home, co-working spaces, or other remote locations rather than commuting to and working in traditional office buildings. This shift has several implications, including increased flexibility for workers, reduced commuting time and expenses, and the ability for companies to tap into talent from diverse geographical areas without the need for physical relocation.

While some individuals still prefer or require the structure and social interaction of a traditional office environment, the rise of remote work options has fundamentally changed the landscape of where and how people work.

Answer:

A

Step-by-step explanation:

Looking at the function, we have;

V(t) = 1,000(1.06)^t

Mathematically, the amount earned on an investment that offers a particular constant percentage return to a particular number of years can be written as;

V = I(1 + r)^t

where V is the value of the investment after some certain number of years

I is the initial amount invested

r is the constant percentage increase

and t is the number of years.

Let’s now re-write what we can deduce in the question.

This is;

V(t) = 1000(1 + 0.06)^t

Thus what this 0.06 represents is r which is the constant interest rate

Step-by-step explanation:

if the term to term rule is to divide by two and the third term in the sequence is 3, you work backwards by multiplying by 2

So 3x2=6

6x2= 12

Thus the first number is 12.

working forward again, you can check your answer. Divide 12 by 2, then divide 6 by 2 and you get 3, the third term if the sequence

The first term of the sequence will be 12.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The term to term rule is divide by 2 the third term of the sequence is 3.

Now,

Since, The term to term rule is divide by 2 the third term of the sequence is 3.

So, We get the second number by multiply the 2 in the third number 3.

Second number = 2 x 3

                         = 6

And, We get the first number by multiply the 2 in the second number 3.

So, First number = 6 x 2

                          = 12

Thus, The first term of the sequence will be 12.

Answer:

direct distance = 65,644.07 feet

horizontal distance = 65,154.77 feet

Step-by-step explanation:

The angle of depression is the angle that the airplane does with the horizontal plane.

So, if this angle is 7° and the airplane is at an altitude if 8000 feet, we can find the direct distance and the horizontal distance using the tangent and the sine relations of the angle.

In the tangent of the angle, the opposite side will be the height of the airplane, and the adjacent side will be the horizontal distance (hd), so:

tangent(7) = 8000 / hd

hd = 8000 / tangent(7) = 65,154.77 feet

In the sine of the angle, the opposite side will be the height of the airplane, and the hypotenusa will be the direct distance (d), so:

sine(7) = 8000 / d

d = 8000 / sine(7) = 65,644.07 feet

y = -6 * x^3

Step-by-step explanation:

We can model the new function as:

f(x) = ax^3

the function y = x^3 have positive values of y for positive values of x, and negative values of y for negative values of x.

As the negative values of x have positive values of y and vice-versa, the first change is to put a negative sign in front of x^3, so we know that 'a' is negative.

Then, for x=1 we have y = -6, so:

-6 = a*1^3

a = -6

So the equation of the transformed function is:

y = -6 * x^3

Answer:

y=−2/3x+3

Step-by-step explanation:

I graphed the point and the equation given below. I used the same slope in the new equation as the original equation. The y-intercept is 3 because the line goes through (0,3).

Thus option C :  [tex]y = -\dfrac{2}{3}x + 3[/tex]  is correct.

Given that:

Equation of considered straight line:

[tex]y = -\dfrac{2}{3}x + 53[/tex]

Let the equation of the straight line that has to be found is given by:

[tex]y = mx + c[/tex]

It is given that the line is parallel to previous straight lines.

Which means  that slope of both the lines are same

or

[tex]m = -\dfrac{2}{3}[/tex]

Now since the second line passes through (-3,5), thus we have:

[tex]5 = -\dfrac{2}{3}\times -3 + c\\or\\c = 3[/tex]

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\frac{1500-0}{400-0}[/tex]

[tex]m=\frac{1500}{400}[/tex]

[tex]m=\frac{15}{4}[/tex]

We can see that line starts at origin (0,0), so y-intercept will be 0.

Now we will slope-intercept form of equation [tex]y=mx+b[/tex], where m represents slope and b represents the y-intercept.

[tex]y=\frac{15}{4}x+0[/tex]

[tex]y=\frac{15}{4}x[/tex]

Answer:

(143/74, -65/148)

Step-by-step explanation:

We have the equations:

4x - 12y = 13

14x + 32y = 13

Let's use elimination, so multiply the first equation by 8 and the second equation by 3:

8 * (4x - 12y = 13)  ⇒  32x - 96y = 104

3 * (14x + 32y = 13)  ⇒  42x + 96y = 39

Add those two equations:

    32x - 96y = 104

+   42x + 96y = 39

________________

    74x  +  0y  =  143

Divide both sides by 74:

x = 143/74

Plug this into an equation to find y:

4x - 12y = 13

4 * (143/74) - 12y = 13

12y = 572/74 - 13 = -390/74

y = -65/148

The answer is (143/74, -65/148).

Answer:

x = 143/74

y = -65/148

Step-by-step explanation:

4x-12y= 13

4x = 13 + 12y

x = 13/4 + 3y

32y+14x=13

32y + 14(13/4 + 3y) = 13

32y + 91/2 + 42y = 13

74y = 13 - 91/2

74y = -65/2

y = -65/148

x = 13/4 + 3(-65/148)

x = 143/74

x = 143/74

y = -65/148
