The  work is required to stretch the spring 80 cm beyond its natural length is 256J.

What is work?

Work in physics is the energy that is transferred to or from an item when a force is applied along a displacement. In its simplest form, it equals the product of the force's magnitude and the distance travelled for a constant force directed in the same direction as the motion.

Let, 100J of work is required to stretch a spring 50cm beyond its natural length.

So,

W = 100 J,

x = 50 cm = 0.5 m

By using the work formula,

\(W = kx^2\\100 = k (0.5)^2\\k = 400\)

To to find the value of W at k = 400 and x = 80 cm = 0.8m

\(W = 400(0.8)^2\\W = 256J\)

Hence, the work is required to stretch the spring 80 cm beyond its natural length is 256J.

Step-by-step explanation:

Garage B is more cost-effective for any parking duration exceeding 2 hours.

When comparing Garage A and Garage B based on their pricing structure, it's important to consider both the flat fee and the hourly rate to determine which option is more cost-effective.

Garage A charges a flat fee of $5, regardless of the duration of parking, and an additional $2 for every hour parked. This pricing structure benefits those who need to park for shorter durations, as the flat fee is relatively low.

However, for longer parking durations, the hourly charge can accumulate significantly, making it less favorable for extended stays.

On the other hand, Garage B follows a different approach by charging a rate of $4.50 per hour with no flat fee. This pricing structure is more suitable for those who require shorter parking times, as they only pay for the exact duration of their stay. In such cases, Garage B would likely be more cost-effective compared to Garage A.

However, for longer stays, Garage A might offer better value. For example, if someone needs to park for 6 hours, Garage A would charge $17 ($5 flat fee + 6 hours * $2/hour) while Garage B would charge $27 ($4.50/hour * 6 hours). In this scenario, Garage A would be the more affordable option.

Ultimately, the choice between Garage A and Garage B depends on the individual's specific parking needs. If the stay is anticipated to be short, Garage B's hourly rate is preferable.

However, for longer durations, Garage A's combination of a flat fee and hourly rate may result in lower overall costs. It's essential to consider the anticipated length of stay to make an informed decision.

Step-by-step explanation:

The distribution shaped for which the mean and median must be about the same will be:

D. Symmetric

E. uniform

In a symmetric distribution, the median is equal to the mean. The bell-shaped distribution is same as the standard normal distribution.

In a right-skewed distribution, the median is much less than the mean and a bimodal distribution is one with two modes.

Therefore, the correct options are D and E.

Step-by-step explanation:

Answer:

\(n=\frac{0.5(1-0.5)}{(\frac{0.025}{1.28})^2}=655.36\)  

And rounded up we have that n=656

Step-by-step explanation:

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 80% of confidence, our significance level would be given by \(\alpha=1-0.80=0.20\) and \(\alpha/2 =0.10\). And the critical value would be given by:

\(z_{\alpha/2}=\pm 1.28 \)

Solution to the problem

The margin of error for the proportion interval is given by this formula:  

\( ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}\)    (a)  

Since we don't have prior info for the proportion of interest we can use \(\hat p=0.5\) as estimator. And on this case we have that \(ME =\pm 0.025\) and we are interested in order to find the value of n, if we solve n from equation (a) we got:  

\(n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}\)   (b)  

And replacing into equation (b) the values from part a we got:

\(n=\frac{0.5(1-0.5)}{(\frac{0.025}{1.28})^2}=655.36\)  

And rounded up we have that n=656

Step-by-step explanation:

\(1meter = 39.37inches \\ 8.104meters = (39.37 \times 8.104)inches \\ = 319.05448inches\)

There are \(3.1496\cdot 10^6\) inches in \(8\cdot 10^4\) meter.

Important information:

Using the given information,

1 meter = 39.37 inches

Using this conversion, we get

\(8\cdot 10^4\) meter = \(39.37\times (8\cdot 10^4)\) inches

\(8\cdot 10^4\) meter = \(39.37\times 80000\) inches

\(8\cdot 10^4\) meter = \(3149600\) inches

\(8\cdot 10^4\) meter = \(3.1496\cdot 10^6\) inches

Therefore, there are \(3.1496\cdot 10^6\) inches in \(8\cdot 10^4\) meter.

Hope this helps :)

Step-by-step explanation:

Since the exponent of the scientific notation is positive, move the decimal point 3 places to the right.

The standard notation of the expression is 2 x 10³ is 2000.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

2 x 10³

Standard notation means writing an expression without any base and exponents.

Now,

10³ can be written as 1000.

Answer:

\((a) \dfrac{dP}{dt} =k P(t)\\(b)P(t)=Ce^{kt}\)

(c)\(P(10)\approx 272\)

(ii)\(P(1000)\approx 26.88 \times 10^{44}\\\)

Step-by-step explanation:

(a)The rate of growth of the population is proportional to the population, this is written as:

\(\dfrac{dP}{dt} \propto P(t)\\$Introducing our proportionality constant, k\\ \dfrac{dP}{dt} =k P(t)\)

(b)

\(\dfrac{dP(t)}{P(t)} =k dt\\$Take the integral of both sides\\\int \dfrac{dP(t)}{P(t)} =\int k dt\\\ln P(t)=kt+C, $C a constant of integration\\Take the exponential of both sides\\e^{\ln P(t)}=e^{kt+C}\\P(t)=e^{kt}\cdot e^C $, (Since e^C$ is a constant, we then have:)\\P(t)=Ce^{kt}\)

(c)

Suppose the net birthrate of the population is .1, and the initial population is 100.

k=0.1

P(0)=100

Substitution into P(t) gives:

\(100=Ce^{kX0}\)

C=100

Therefore:

\(P(t)=100e^{0.1t}\)

(i)When t=10

\(P(10)=100e^{0.1 \times 10}\\=271.8\\\approx 272\)

(ii)When t=1000

\(P(1000)=100e^{0.1 \times 1000}\\=26.88 \times 10^{44}\\\)

An equation is an algebraic equality in which letters appear with unknown value.

In an equation appears:

The solution of a equation means determining the value that satisfies it. In this way, by changing the unknown to the solution, the equality must be true. To solve an equation, keep in mind:

Being "y" a number, and knowing that sum of a number and -3 is -8, the equation in this case is:
