The spring .2m far when it is compressed on being supported by a mass of 10kg.

Given: Mass of 30 kg which compresses spring by 0.6m

To find: The compression of the spring when it is supported by a mass of 10 kg

Concept: Compression springs are coiled springs that hold mechanical energy in a compressed state. When these springs are subjected to compressive loads, they compress and shorten, capturing and storing significant potential force.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

By using unitary method,

10 is 3 times less than 30.

so, 30/3=10

Also applying the same proportion over the lengths compressed,

we get, 0.6/3=.2

Answer:

10√2

Step-by-step explanation:

The square root of 200 in its simplest radical form is 10√2.

If we know the prime factorization of a number, we can write the radical form of the square root of that number. As a result, the prime factorization of 200 is 2 × 2 × 2 × 5 × 5.

As a result, the square root of 200 in the simplest radical form should be 10√2.

Answer:

12(x+y)=42

60(y-x)=42

Step-by-step explanation:

60(y-x)=42 (1 minute = 60 seconds, x-y speed each second, 42 metres)

It takes 3 hours for the cats to catch 27 fish in the pond.

Zarko can catch 5 fish per hour.

Manchu can catch 2 fish every 0.5 of an hour, so in an hour, the cat would catch 2 times that, which is 4 fish.

When working together, the cats can catch 4 + 5 = 9 fish per hour

If the cats work for x hours, then they catch 9*x fish.

To get the time that takes them to catch 27 fish we just need to solve the linear equation:

9x = 27

Solving for x:

x = 27/9 = 3

It takes 3 hours for the cats to catch 27 fish in the pond.

The half life of the radioactive Rutherford-265 is;

13.1 hours.

It follows from the task content that the given function represents the decay function of the radioactive material. Since half-life corresponds to the point at which only half of the starting material remains, hence we have;

(1/2) = e ^(-0.053t)

By taking the natural log of both sides, we have;

-0.6931 = -0.053t

Hence, t = -0.6931/ -0.053 = 13.1 hours.

We have an exponential growth. The domain is the set of all real numbers and the range is R: (0, ∞).

Here we have the exponential function:

[tex]h(x) = 125^x[/tex]

Notice that the base, 125, is larger than 1, which means that we have an exponential growth.

Now, the domain of any exponential equation is the set of all real numbers.

For the range, as x tends to negative infinity, the function will tend to zero.

And as x tends to infinity, h(x) also tends to infinity.

So the range is R: (0, ∞).

The Inventory Turnover for 2021 is 5.9 times and for 2022 is 10 times.

2021

Inventory Turnover = Cost of Goods sold / Average Inventory

Cost of Goods sold = $1,165,250/[($170,000+$225,000)/2]

Cost of Goods sold = $1,165,250/($395,000/2)

Cost of Goods sold = $1,165,250/197,500

Cost of Goods sold = 5.9 times

2022

Inventory Turnover = Cost of Goods sold / Average Inventory

Cost of Goods sold = $1,525,000/[($225,000+$80,000)/2]

Cost of Goods sold =  $1,525,000/($305,000/2)

Cost of Goods sold =  $1,525,000/152,500

Answer:

  15.4 years

Step-by-step explanation:

An investment is doubled when it is twice its initial value. The equation can be solved for the value of t that makes this true.

In the exponential equation for investment value, the factor y₀ is the initial value of the investment. We want to find t when y = 2y₀.

  2y₀ = y₀·e^(0.045t)

Dividing by y₀ gives ...

  2 = e^(0.045t)

Taking natural logarithms, we have ...

  ln(2) = 0.045t

Dividing by the coefficient of t gives its value:

  t = ln(2)/0.045 ≈ 15.4

The investment will be doubled after 15.4 years.

__

Additional comment

The continuously compounded interest rate for this investment is 4.5%. The doubling time is 0.693 divided by this: 0.693/0.045 ≈ 15.4. This relationship holds for any sort of continuous compounding.

The required Comparison of the inequalities are

The range of values encompassing the region's junction is (-13, 15).

When comparing two numbers, an inequality indicates whether one is less than, larger than, or not equal to the other.

We take into account the various variables of the inequality

|x – 1| + 1 > 15

Therefore

|-x-1|+1-1<15-1

|-x-1|-1 <14

13<x<15

The required region lies between the inequality -13 <x< 15.

Simplify the inequality Ix-11+1 > 15 we get,

Step-by-step explanation:

OK, The pet snail only moves a foot per day because at night it falls again, SO ima going with 16 days.

[<Answer>] (2):
Hello! I'm Avery. And I'm here to help! :)

----------------------------------------------------------------------------------------------------------

[<The Explanation>}:

Sally has  pet snail that fell into a well.

(Depth of the well = 16 feet)

Snail climbs up 5 feet but each night it slides back down 4 feet.

So the snail climbs up per day = 5 feet - 4 feet = 1 feet.

Number of days snail took to reach at 11 feet = 11 × 1 = 11 feet

Remaining distance to cover by the snail = 16 - 11 = 5 feet

Number of days to cover remaining 5 feet to reach the top of the well = 1 day

Therefore, snail will take 12 days to reach the top of the well.

5.7099 is the margin of error.

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean.

Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.

According to the question,

The standard sampling error of the sample mean is σₓ ,

The sampling distribution is: N (u,σₓ/n)

Therefore,

By using the standard deviation formula:

σₓ = √∑(xi -μ)/N

Where,

∑= population standard deviation

N= the size of the population

xi= each value from the population

μ =the population mean

So ,

σₓ = [tex]\frac{20.6}{\sqrt{50} }[/tex] = 2.913

Since, a = 1- 95% = 0.05

therefore [tex]Z\frac{a}{2}[/tex] = (1-0.005 x 2) = 1.959964

Here, the margin of error for a 95% confidence interval for this sample is given by:

[tex]Z\frac{a}{2}[/tex] * σₓ = 1.959964 x 2.913    

           = 5.7099
