The average time it takes to fill one bag of leaves is 0.17 hours or 10 minutes.

The average time it takes to fill one bag of leaves is 0.17 hours or 10 minutes.

To find the average time it takes to fill one bag of leaves, we need to divide the total time spent raking leaves by the number of bags filled. In this case, the total time spent raking leaves is 12 hours and the number of bags filled is 48.

Therefore, the average time it takes to fill one bag of leaves is:

Average time = Total time / Number of bags filled

Average time = 12 hours / 48 bags = 0.25 hours/bag = 15 minutes/bag.

The derivative of [tex]\( f(x) = \frac{7x}{3 + x^2} \)[/tex]  is [tex]\( f'(x) = \frac{-7x^2 + 21}{(3 + x^2)^2} \)[/tex].

To find the derivative of the function [tex]\( f(x) = \frac{7x}{3 + x^2} \)[/tex] , we can use the quotient rule. The quotient rule states that if you have a function [tex]\( g(x) = \frac{u(x)}{v(x)} \)[/tex] , then the derivative [tex]\( g'(x) \)[/tex] is given by:

[tex]\[ g'(x) = \frac{u'(x)v(x) - u(x)v'(x)}{[v(x)]^2} \][/tex]

In this case, let u(x) = 7x  and v(x) = 3 +[tex]x^2[/tex] . Now, find the derivatives u'(x)  and  v'(x):

u'(x) = 7

v'(x) = 2x

Now, apply the quotient rule:

[tex]\[ f'(x) = \frac{(7)(3 + x^2) - (7x)(2x)}{(3 + x^2)^2} \][/tex]

Simplify the expression:

[tex]\[ f'(x) = \frac{21 + 7x^2 - 14x^2}{(3 + x^2)^2} \][/tex]

Combine like terms:

[tex]\[ f'(x) = \frac{-7x^2 + 21}{(3 + x^2)^2} \][/tex]

So, the derivative of [tex]\( f(x) = \frac{7x}{3 + x^2} \)[/tex]  is [tex]\( f'(x) = \frac{-7x^2 + 21}{(3 + x^2)^2} \)[/tex].

Answer:

cosθ =  [tex]\frac{3}{5}[/tex] .

Step-by-step explanation:

Given : If sinθ =4/5 .

To find :  cosθ = _____.

Solution : We have given that sinθ =4/5 .

By the trigonometric identity

cos²θ + sin²θ = 1.

Plugging the value of sinθ =4/5 .

cos²θ + [tex](\frac{4}{5}) ^{2}[/tex] = 1.

cos²θ + [tex]\frac{16}{25}[/tex] = 1.

On subtracting  [tex]\frac{16}{25}[/tex]  from both sides

cos²θ = 1 -  [tex]\frac{16}{25}[/tex] .

cos²θ =  [tex]\frac{25 -16}{25}[/tex] .

Taking square root both sides.

[tex]\sqrt{cos^{2}theta}  = \sqrt{\frac{9}{25}}[/tex] .

cosθ =  [tex]\frac{3}{5}[/tex] .

Therefore, cosθ =  [tex]\frac{3}{5}[/tex] .

The athlete will eat 2.45 kilograms of protein during 7 weeks of training.

To find out how much protein the athlete will eat during 7 weeks of training, we can simply multiply the amount of protein eaten per week by the number of weeks of training.

Given:

Protein eaten per week = 0.35 kg

Number of weeks of training = 7 weeks

Protein eaten during 7 weeks of training = 0.35 kg/week * 7 weeks

Now, calculate the result:

Protein eaten during 7 weeks of training = 2.45 kg

So, the athlete will eat 2.45 kilograms of protein during 7 weeks of training.

Final answer:

After three days, starting with 9-2x widgets, producing 2x+1 widgets daily, and destroying 3-x widgets daily, the student is left with 3 + 7x widgets, in terms of x.

Explanation:

Let's find out how many widgets are left after three days, starting with 9-2x widgets, producing 2x+1 widgets daily, and destroying 3-x widgets daily.

To calculate the total number of widgets after one day, we add the produced widgets (2x+1) and subtract the destroyed widgets (3-x) from the initial amount (9-2x):

At end of day 1: (9-2x) + (2x+1) - (3-x) = 9 - 2x + 2x + 1 - 3 + x = 7 + x

Repeat this process for two more days:

At end of day 2: (7+x) + (2x+1) - (3-x) = 7 + x + 2x + 1 - 3 + x = 5 + 4x

At end of day 3: (5+4x) + (2x+1) - (3-x) = 5 + 4x + 2x + 1 - 3 + x = 3 + 7x

Therefore, after three days, you are left with 3 + 7x widgets, in terms of x.

The student initially has 9-2x widgets, and each day there's a net change of 3x-2 widgets. After three days, the student is left with 7x+3 widgets.

The student starts with 9-2x widgets. Each day, they produce 2x+1 widgets and destroy 3-x widgets. To find out how many widgets the student is left with after three days, we need to account for the daily production and the daily destruction of widgets and sum them up over the three days.

Let's calculate the daily net change in widgets. The number of widgets produced each day is 2x+1, and the number destroyed is 3-x, so the net change in widgets each day is:

(2x+1) - (3-x) = 2x + 1 - 3 + x = 3x - 2

Now, let's multiply this daily net change by three days:

3 days × (3x - 2) = 9x - 6

Finally, let's add this to the initial number of widgets to find the total:

(9-2x) + (9x - 6) = 9 - 2x + 9x - 6 = 7x + 3

Therefore, after three days, the student is left with 7x + 3 widgets in terms of x.

Final answer:

The mean and standard deviation of the new random variable y, derived from a distribution x with a given mean and standard deviation, are calculated by applying transformations, resulting in a mean of 47 and a standard deviation of 12.

Explanation:

The question asks us to find the mean and standard deviation of a new random variable y = 4x - 5, given a distribution, x, with a mean of 13 and a standard deviation of 3. To calculate the mean of y, we use the transformation y = 4x - 5. The mean of y can be found by substituting the mean of x into this equation, giving us 4(13) - 5 = 52 - 5 = 47. To find the standard deviation of y, we multiply the standard deviation of x by the coefficient of x in the equation, resulting in 3 * 4 = 12. Therefore, the mean of y is 47, and the standard deviation is 12.

Next numbers: 3430, 24010

Step-by-step explanation:

AS you can see you just need to discover the pattern by dividing the subsequent numbers by the direct number before that:

490/70=7

70/10=7

So both numbers indicate the patter on multiply by 7.

So to calculate the next number we first have to multiply 490*7= 3430

Now we just have to multiply the 3430 by 7 and that would be 24010.

So the next numbers would be 3430 and 24010,
