A total of 2.25 ft-lb work is needed to stretch it 18 in. beyond its natural length.

One foot is equal to 12 inches, so 3 ft is equal to 36 inches. To stretch the spring 18 inches beyond its natural length, we need to perform work on it to stretch it an additional 18/36 = 1/2 of the 3 ft distance. If the work required to stretch it 3 ft is 6 ft-lb, then to stretch it 1/2 of that distance, we would need 1/2 of the work, or 6/2 = 3 ft-lb. The work needed to stretch the spring 18 inches beyond its natural length is 3 ft-lb * 18 inches/12 inches/ft = 2.25 ft-lb.

the circumference of the circle is 19.4568 cm or, rounded to two decimal places, 94.68 cm.

94.68 cm

The formula for circumference of a circle is C = 2πr, where r is the radius of the circle. Therefore, to find the circumference of the circle, we need to first calculate the radius.

The area of the circle is given as A = πr2.

Therefore, we can rearrange this equation to solve for the radius, which is

r = √(A/π)

Plugging in the given area, A = 3.14, we get

r = √(3.14/π) = √(3.14/3.14) = 1

Now, we can use the circumference formula to calculate the circumference, which is

C = 2πr = 2π(1) = 2π × 3.14 = 6.28 × 3.14 = 19.4568

Therefore, the circumference of the circle is 19.4568 cm or, rounded to two decimal places, 94.68 cm.

We can tell that Mike thought the difference would be 72, but it is actually 72.74 by rounding off.

A number is simplified when it is rounded off, preserving its value while moving it closer to the next number.

It is done for whole numbers as well as decimals at various places of hundreds, tens, tenths, etc.

When numbers are rounded off, the important numbers are kept.

To determine how to round a number, look at the next digit in the appropriate position; if it is less than 5, round down, and if it is greater than 5, round up.

So, Mike determined 79 to be 79.44 and 7 to be 6.7, so he determined the difference as follows:

79 - 7 = 72

Actual numbers that vary are:

79.44 - 6.7 = 72.74

Therefore, we can tell that Mike thought the difference would be 72, but it is actually 72.74 by rounding off.

The sample mean is significantly different from the population mean. The confidence level used was 95%.

To build a confidence interval to decide whether this example mean is fundamentally not the same as the populace mean, there are a few stages that should be taken.

To begin with, work out the standard error of the mean (SEM) for the example, which is the standard deviation separated by the square base of the example size (SEM = σ/√n). For this situation, the SEM is 3/5 = 0.6 mcg/dL.

Then, compute the critical value for the confidence interval picked by increasing the SEM by the t-esteem from the t-dissemination for the given confidence interval. For instance, in the event that a 95% confidence interval is picked, the t-esteem is 1.96. This provides us with a basic worth of 0.6 x 1.96 = 1.176 mcg/dL.

At last, build the certainty span utilizing the example mean and the basic worth. The certainty span is (15 - 1.176, 15 + 1.176), or (13.824, 16.176). This implies that we are 95% sure that the genuine populace mean exists in this reach.

What is the equation straight line?

The formula for a straight line is generally expressed as Y = mx + c, where m stands for the slope and c for the y-intercept. In geometry, it is the straight-line version of the equation that is most usually utilised. A straight-line's equation can be expressed in a variety of forms, including point-slope form, slope-intercept form, general form, standard form, etc. An infinitely long straight line has two dimensions and is a geometrical object with two ends. The equations for a straight line that are used the most frequently are y = mx + c and axe + by = c. Point-slope, slope-intercept, standard, general, and other forms are more variations.

The given line is y = x/5 +3

the slope is m = 1/5

So the slope of the perpendicular line will be -5

So the equation of line will be y-3 = m1(x-1)+3

y-3 = -5x+5+3

y = -5x +11

Hence the equation for the line will be y = -5x +11.

this is how I got the answer

Answer:

Step-by-step explanation:

To graph the equation 3y = -6x - 12, we can start by finding the x and y intercepts.

The x-intercept is the point where y = 0, so we can substitute 0 for y in the equation:

3y = -6x - 12

3 * 0 = -6x - 12

0 = -6x - 12

12 = -6x

x = -2

So the x-intercept is (-2, 0).

The y-intercept is the point where x = 0, so we can substitute 0 for x in the equation:

3y = -6x - 12

3y = -6 * 0 - 12

3y = -12

y = -4

So the y-intercept is (0, -4).

Now that we have the x and y intercepts, we can plot the points on the graph and draw a line that passes through both points. This line will be the graph of the equation.

In this case, the graph of the equation 3y = -6x - 12 is a downward sloping line that passes through the points (-2, 0) and (0, -4).

1 4/5 bags of dog food will last the LPS for approximately 8 and 3/10 days, or 8.3 days.

The Logan pet store uses 9/10 of a bag of dog food every day, which means they need 9/10 * 1 bag = 9/10 bags of dog food per day. To determine how many days 1 4/5 bags of dog food will last,

we need to divide the total amount of dog food by the amount used per day: 1 4/5 bags / (9/10 bags/day) = (9/10)*(18/5) / (9/10) = 18/5 days. Therefore, 1 4/5 bags of dog food will last for 18/5 days.

One 4/5 bags of dog food will last the Logan Pet Store (LPS) for approximately 8 and 3/10 days. This is because if the LPS uses 9/10 of a bag of dog food every day, then they are using 9/10 * 5/5 = 9/10 bags of dog food per day. If we divide 1 4/5 bags of dog food by 9/10 of a bag per day, we get (1 4/5) / (9/10) = (18/5) / (9/10) = 18/5 * 10/9 = 20/9 days. Therefore, 1 4/5 bags of dog food will last the LPS for approximately 8 and 3/10 days, or 8.3 days.

A bone fragment that has 10% of the parent Pb-210 remaining with half-life of Pb-210 is 22 years, the bone fragment is approximately 51 years old.

To determine the age of the bone fragment, you need to calculate the number of half-lives that have elapsed since the bone was formed. The age of the bone can be calculated using the formula:

age = number of half-lives * half-life

To calculate the number of half-lives, you need to determine how much of the original Pb-210 has decayed. If a bone fragment has 10% of the parent Pb-210 remaining, then 90% has decayed.

You can calculate the number of half-lives by taking the natural logarithm of the ratio of the remaining amount of Pb-210 to the original amount:

number of half-lives = ln(0.10) / ln(0.5)

Using the half-life of Pb-210, which is 22 years, you can now calculate the age of the bone fragment:

age = number of half-lives * 22 years

Substituting the values and calculating the number of half-lives and the age of the bone fragment, you get:

number of half-lives = ln(0.10) / ln(0.5) = 2.302

age = number of half-lives * 22 years = 51.064 years

So, the bone fragment is approximately 51 years old.
