The derivative of y = (x³ + 2)²(x⁴ + 4)⁴ using logarithmic differentiation is;

y' =  {[6x²In(x³ + 2)]/(x³ + 2)} + {[16x³In(x⁴ + 4)⁴]/(x⁴ + 4)} × [(x³ + 2)²(x⁴ + 4)⁴]

We are given the function;

y = (x³ + 2)²(x⁴ + 4)⁴

We want to find the derivative using logarithmic differentiation;

Step 1; Take the natural log of both sides;

In y = In[(x³ + 2)²(x⁴ + 4)⁴]

Step 2;

Using log of a product property on this, we have;

In y = In(x³ + 2)² + In(x⁴ + 4)⁴

Step 3; We will now differentiate both sides with chain rule to get;.

y'/y = [6x²In(x³ + 2)]/(x³ + 2) + [16x³In(x⁴ + 4)⁴]/(x⁴ + 4)

Step 4; Using multiplication property of equality, multiply both sides by y to get;

y' =  {[6x²In(x³ + 2)]/(x³ + 2) + [16x³In(x⁴ + 4)⁴]/(x⁴ + 4)} × y

Step 5; Plug in the value of y = (x³ + 2)²(x⁴ + 4)⁴ to get;

y' =  {[6x²In(x³ + 2)]/(x³ + 2)} + {[16x³In(x⁴ + 4)⁴]/(x⁴ + 4)} × [(x³ + 2)²(x⁴ + 4)⁴]

At 9:00 p.m, the temperature would be equal to -0.4°C

We have got an equation that can relate these three units of measurement of temperature, as given below:

[tex]\dfrac{C}{5} = \dfrac{F - 32}{9} = \dfrac{K - 273}{5}[/tex]

where C represents the measurement of a fixed temperature in celsius, F represents the measurement of that same intensity temperature in fahrenheit, and K represents the measurement of equally intense temperature in kelvin.

We are given that

On a winter day in Alaska, the temperature at noon = -0.6°C.

Then From noon to 3:00, the temperature increased by 1.2°C. From 3:00 to 6:00, it dropped 0.4°C, and from 6:00 to 9:00, it decreased by 0.6°C.

-0.4

Therefore, the expression could be;

-0.6+1.2-0.4-0.6

=-0.4

The expression that shows the temperature in °C at 9:00 p.m is -0.6+1.2-0.4-0.6

To convert gallons to cups, multiple conversion factors can be used. Assuming a typo in '4 4/1 gallons' and correcting it to '4 gallons,' the conversion shows that there are 16 cups in a gallon. Thus, 4 gallons of water is equivalent to 64 cups.

To convert gallons to cups, you can use conversion factors that relate these two units of volume. First, we need to correct the expression given for the volume of water in the pail. It seems there is a typo because '4 4/1 gallons' isn't a proper number. Assuming it's intended to be '4 gallons,' we can proceed with the conversion.

Since 1 gallon is equivalent to 4 quarts and 1 quart is equivalent to 2 pints, and 1 pint is equivalent to 2 cups, we can create a chain of multiplications to convert from gallons to cups.

Multiplying these together gives us:

1 gallon = 4 x 2 x 2 = 16 cups

Therefore, to find out how many cups are in 4 gallons:

4 gal x 16 cups/gal = 64 cups

So, 4 gallons of water is equivalent to 64 cups.

Final answer:

To convert 4 gallons to cups using the provided conversion factors, multiply the gallons by 4 to get quarts, then multiply by 2 to get pints, and again multiply by 2 to get cups, resulting in a total of 64 cups.

Explanation:

The student's question involves converting a quantity of gallons into cups, which is a Mathematics problem specifically dealing with units of volume conversion. The amount given, 4 4/1 gallons, seems to be a typo, but assuming the intention was to convert 4 gallons into cups, we can use the given conversion factors:

To find out how many cups are in 4 gallons, we follow these steps:

Therefore, 4 gallons is equivalent to 64 cups.

Final answer:

Dots sold 192 T-shirts and 64 shorts in April. We found this by setting up a system of equations with the given information and solving for the number of T-shirts (T) and shorts (S) sold.

Explanation:

To solve the problem of how many T-shirts and shorts Dots sold, we use a system of equations. Let's denote the number of T-shirts as T and the number of shorts as S. Given that T-shirts cost $2 each and shorts cost $3 each, and the total sales were $576, we can write our equations as follows:

2T + 3S = $576

We are also told that the store sold 3 times as many T-shirts as shorts, which gives us the second equation:

T = 3S

Substituting the second equation into the first, we get:

2(3S) + 3S = $576

6S + 3S = $576

9S = $576

Now, dividing both sides by 9 to isolate S, we get:

S = $576 / 9

S = 64

Since T is three times S:

T = 3 × 64

T = 192

Therefore, Dots sold 192 T-shirts and 64 shorts in April.

Answer:

7.6 inches

Step-by-step explanation:

The ratio of the height to the width of a packaging label is 5 to 19, that is,

h/w = 5/19 [1]

If the height of the label is 2 inches, and its width is unknown (x), that is,

h/w = 2 in/x [2]

We can set up a proportion with [1] and [2],

5/19 = 2 in/x

We use the cross product property of proportions.

5 × x = 19 × 2 in

x = 19 × 2 in/ 5 = 7.6 in

The width is 7.6 inches.

Answer: 3*2^-3a^2b^3c^5x^-4y^-3z^-1 (graded correct)

Step-by-step explanation:

meaganblatcher (original poster)

you take away 8 and multiply  and get 3a^2b^3c^5 * x^4y^3z or something

This becomes 3a^2b^3c^5x^-4y^-3z^1/8

Then you move the 8 up using multiplication and get -24a^2b^3c^5x^4y^3z^1

This can be simplifed as 3*2^-3a^2b^3c^5x^-4y^-3z^-1

regardless that's the real answer.

The 95% confidence interval for the mean number of hours Americans spend relaxing or engaging in enjoyable activities post-work is between 1.38 and 1.92 hours per day, which signifies the statistical range where the true mean likely falls. This statistic is crucial for understanding leisure's role in health and well-being.

The 95% confidence interval given in the General Social Survey of (1.38, 1.92) hours for the mean number of hours spent relaxing or pursuing activities after an average workday suggests that we can be 95% confident that the actual mean number of hours all Americans have for such activities falls within this range. This is an important statistic considering that leisure and recovery are essential for well-being, mental health, and stress prevention, as pointed out by researchers like Sonnentag & Zijlstra and Juliet Schor. Juliet Schor also highlighted that Americans have significantly declined in leisure time. The comparison of leisure time across different countries, such as Americans working more hours compared to Europeans, adds context to the importance of this interval in reflecting Americans' potential lack of leisure that could impact health.

Answer:

The answer is [tex]4x^3-29x^2+10x-21[/tex]

Step-by-step explanation:

In order to determine the answer, we have to know what it means (t*s)(x).

When we need to multiply two functions, where y(x) and z(x) are the functions, we can describe the process with the notation (y*z) (x). This notation means that the function y(x) is being multiplying by the function z(x).

So, in this case, we have two functions:

[tex]s(x)=x-7\\t(x)=4x^2-x+3[/tex]

Multiplying both functions (t*s) (x):

[tex](t*s)(x)=t(x)*s(x)\\(4x^2-x+3)(x-7)\\4x^3-28x^2-x^2+7x+3x-21\\4x^3-29x^2+10x-21[/tex]

Finally, the expression is:

[tex]4x^3-29x^2+10x-21[/tex]
