The minimum and the maximum values are 0 and 1/27, respectively.

The extreme values of a function are the minimum and the maximum values of the function.

The function is given as:

f(x, y, z) = x²y²z²

x² + y² + z² = 1

Subtract 1 from both sides of x² + y² + z² – 1

x² + y² + z²-1=0

Using Lagrange multiplies, we have:

L(xy.z. λ) f(x. y.z) + λ(0)

Substitute f(x.y. z) = x³y²z² and x² + y² + z² − 1 = 0

L(x, y, λ) = x²y²z² + λ(x² + y² + 2² – 1)

Differentiate

Lx = 2xy²z² + 2λx

Ly = 2x²yz² + 2λy

Lz = 2x²y³z + 2λz

Lλ = x² + y² + z²

Equate to 0

2xy²z² + 2λx = 0

2x²yz² + 2λy = 0

2x²y²z+ 2λz = 0

x² + y² + z²-1=0

Factorize the above expressions

2xy²z²+2λx = 0

2x(y²z² + λ) = 0

2x = 0 or y²z²+λ=0

x=0 or y²z² = -λ

2x²yz² + 2λy = 0

2y(x²z² + λ) = 0

2y=0 or x²z²+λ=0

y = 0 or x²z² = -λ

2x²y²z+λz = 0

2z(x²y² + λ) = 0

2z = 0 or x²y² +λ=0

z = 0 or x²y² = -λ

So, we have:

x = 0 or y²z² = -λ

y=0 or x²z² = -λ

z = 0 or x²y² = -λ

Because

-λ= -λ

The above expressions become:

x=y=z=0

x²z² = y²z²

x² = y²

x = ±y

Also, we have:

x²y² = x²z²

y² = z²

y = tz

Also:

y²z² = x²y²

z² = x²

z = ±x

So, we have:

x = ±y

y = ±z

z = ±x

This means that:

x=y=z

Recall that: x² + y² + z² = 1

So, we have:

x² + x² + x² = 1

3x² = 1

Divide through by 3

x² = 1/3

Take square roots of both sides

x=±[tex]\frac{1} \sqrt{3}[/tex]

So, we have:

x=y=z=±[tex]\frac{1} \sqrt{3}[/tex]

So, the critical points are:

x=y=z=0

x=y=z=±[tex]\frac{1} \sqrt{3}[/tex]

Substitute the above values in f(x, y, z)=x²y²z²

f(0,0,0) = 0² × 0² × 0² = 0

f(±[tex]\frac{1} \sqrt{3}[/tex],±[tex]\frac{1} \sqrt{3}[/tex],±[tex]\frac{1} \sqrt{3}[/tex]) = (±±[tex]\frac{1} \sqrt{3}[/tex])² × (±±[tex]\frac{1} \sqrt{3}[/tex])² × (±±[tex]\frac{1} \sqrt{3}[/tex])² =[tex]\frac{1}{27}[/tex]

Considering the above values, we have:

a) The standard error of the mean is equal to the standard deviation divided by the square root of the sample size. In this case, the standard error of the mean would be equal to 23.65/sqrt(8) = 6.61.

b) Using the central limit theorem, we can say that the probability that the mean of the eight plots would be within 1 standard error of the mean is approximately equal to 68%. This is because, under the central limit theorem, the distribution of the sample means approaches a normal distribution with a mean equal to the population mean and a standard deviation equal to the population standard deviation divided by the square root of the sample size. Therefore, in this case, we would expect that 68% of the sample means would be within 1 standard deviation of the population mean.

c) The probability that we calculated in (b) might not be very accurate because the central limit theorem assumes that the underlying population is normally distributed. However, it is not clear from the histogram whether the number of live maples per plot is normally distributed. If the distribution of the number of live maples per plot is not normal, then the central limit theorem would not be applicable and the probability we calculated might not be accurate.

Let sn be the number of successes in n independent bernoulli trials, the probability of success for each trial is 1/2.

(a) 1 , (b) 0 ,(c) 0

(a) As n approaches infinity, the probability of having 2n - 3n successes in n trials is equal to the probability of having 2n + 3n successes in n trials. Since the probability of success for each trial is 1/2, the probability of having 2n - 3n successes is the same as the probability of having 2n + 3n successes. Therefore, the limit is 1.

(b) As n approaches infinity, the probability of having 2n - 4n successes in n trials is equal to 0, since the probability of success for each trial is 1/2. Similarly, the probability of having 2n + 4n successes in n trials is also equal to 0. Therefore, the limit is 0.

(c) As n approaches infinity, the probability of having 2n - 20 successes in n trials is equal to 0, since the probability of success for each trial is 1/2. Similarly, the probability of having 2n + 20 successes in n trials is also equal to 0. Therefore, the limit is 0.

The return from opening the office building under the assumption that it is leased would be the difference between the net income generated by the increase in sales and the expenses associated with opening the new office, including the cost of leasing the office space.

To calculate the net income generated by the increase in sales, we first need to calculate the total cost of goods sold. Since the cost of goods sold is estimated to be 40 percent of sales, the cost of goods sold for the new office would be 40 percent x $2.6 million = $<<40*.01*2.6=1.04>>1.04 million.

Subtracting the cost of goods sold from the increase in sales, we find that the net income generated by the increase in sales would be $2.6 million - $1.04 million = $<<2.6-1.04=1.56>>1.56 million.

Next, we need to calculate the expenses associated with opening the new office, including the cost of leasing the office space. Since the corporate overhead would increase by $306,500, the total up-front costs associated with opening the new office would be $306,500 + $2.6 million = $<<306.5+2.6=2.906>>2.906 million.

To calculate the cost of leasing the office space, we need to multiply the annual lease payment by the number of years in the lease term. Since the annual lease payment is $645,000 and the lease term is 15 years, the total cost of leasing the office space would be $645,000 x 15 years = $<<645000*15=9675000>>9.675 million.

Subtracting the total up-front costs and the cost of leasing the office space from the net income generated by the increase in sales, we find that the return from opening the office building under the assumption that it is leased would be $1.56 million - $2.906 million - $9.675 million = $<<1.56-2.906-9.675=-9.020>>-9.020 million. This means that the corporation would incur a loss of $9.020 million by opening the new office and leasing the office space.

To calculate the return on the incremental cash flow from owning versus leasing, we need to subtract the cash flow from leasing the office space from the cash flow from owning the office space.

First, let's calculate the cash flow from leasing the office space. We already know that the total cost of leasing the office space would be $9.675 million. To calculate the cash flow from leasing the office space, we need to subtract the real estate operating expenses from the total cost of leasing the office space. Since the real estate operating expenses are estimated to be 50 percent of the lease payments, the real estate operating expenses would be 50 percent x $645,000 = $<<50*.01645=322500>>322,500 per year. Since the lease term is 15 years, the total real estate operating expenses would be $322,500 x 15 years = $<<322.515=4837.5>>4,837,500. Subtracting the real estate operating expenses from the total cost of leasing the office space, we find that the cash flow from leasing the office space would be $9.675 million - $4.837.5 million = $<<9.675-4.837.5=4.837.5>>4,837,500.

Next, let's calculate the cash flow from owning the office space. We already know that the total up-front costs associated with opening the new office would be $2.906 million. To calculate the cash flow from owning the office space, we need to subtract the total annual operating expenses from the net income generated by the increase in sales. Since the net income generated by the increase in sales is $1.56 million and the total annual operating expenses are $217,774.36, the cash flow from owning the office space would be $1.56 million - $217,774.36 = $<<1.56-217774.36=1.34222564>>1,342,225.64.

Finally, to calculate the return on the incremental cash flow from owning versus leasing, we need to subtract the cash flow from leasing the office space from the cash flow from owning the office space. Therefore, the return on the incremental cash flow from owning versus leasing would be $1,342,225.64 - $4,837,500 = $<<1.34222564-4.837.5=-3.495.5>>-3,495,500. This means that the corporation would incur a loss of $3.495.5 million by choosing to own the office space instead of leasing it.

Step-by-step explanation:

The equation for the volume of water in the bowl after a certain amount of time can be represented by the formula: y = k * x, where k is the constant of proportionality. This constant represents the rate at which water is dripping into the bowl, in milliliters per second.

To find the constant of proportionality, you need to know the rate at which the water is dripping into the bowl. If you know the rate, you can plug it into the formula above to find the equation that represents the volume of water in the bowl over time. For example, if the water is dripping into the bowl at a rate of 1 milliliter per second, the equation would be: y = 1 * x. This means that after 1 second, the bowl would contain 1 milliliter of water, after 2 seconds it would contain 2 milliliters of water, and so on.

It's important to note that the constant of proportionality will change if the rate at which the water is dripping into the bowl changes. For example, if the water is dripping into the bowl at a rate of 2 milliliters per second, the equation would be: y = 2 * x. This means that after 1 second, the bowl would contain 2 milliliters of water, after 2 seconds it would contain 4 milliliters of water, and so on.

In summary, the equation for the volume of water in the bowl after a certain amount of time can be represented by the formula: y = k * x, where k is the constant of proportionality, which represents the rate at which water is dripping into the bowl. To find the equation, you need to know the rate at which the water is dripping into the bowl, and plug that value into the formula as the value of k.

At a time t hours after taking a tablet, the rate at which a drug is being eliminated is r(t) = 50(e^-0.1 t - e^-0.20 t) mg/hr. Assuming that all the drug is eventually eliminated, calculate the original dose. Enter the exact answer. The original dose was 0 mg.

A limit is a value that a function or sequence approaches as the input or index approaches a certain value. Limits are a fundamental concept in calculus, and they are used to define important ideas such as derivatives and integrals. They are also used in other areas of mathematics, such as real analysis and mathematical analysis.

The rate at which the drug is being eliminated is the derivative of the amount of drug present at time t. We can write this as:

r(t) = dA(t)/dt = 50(e^-0.1 t - e^-0.20 t) mg/hr

If we integrate both sides of this equation with respect to t, we get:

A(t) = ∫r(t) dt = ∫50(e^-0.1 t - e^-0.20 t) dt

This integral can be evaluated using integration by parts. Let u = e^-0.1 t and dv = e^-0.20 t. Then du = -0.1 e^-0.1 t and v = -1/(0.2) * e^-0.20 t = -5e^-0.20 t. We can then write:

A(t) = -5 ∫e^-0.1 t * e^-0.20 t dt + (1/0.2) ∫e^-0.1 t dt

The first integral on the right-hand side can be evaluated using the substitution y = -0.3t, which gives:

A(t) = -5 ∫e^y dy + (1/0.2) ∫e^-0.1 t dt

The first integral is simply -5e^y, and the second integral is -5e^-0.1 t. Substituting these results back into the expression for A(t) gives:

A(t) = -5(-5e^-0.3 t) + (1/0.2)(-5e^-0.1 t)

Combining constants and simplifying gives:

A(t) = 25e^-0.1 t - 25e^-0.3 t

We are told that all the drug is eventually eliminated, so A(t) approaches 0 as t approaches infinity. This means that the original dose A(0) must be equal to the limit of A(t) as t approaches 0.

Taking the limit as t approaches 0 gives:

A(0) = lim t → 0 [25e^-0.1 t - 25e^-0.3 t]

This limit is equal to 25 - 25 = 0, so the original dose was 0 mg.

1,000  at $  900

Total    $ 11,850,000

cost of good sold:

28,000 x $900 = $25,200,000

sales revenue

28,000 x 900 x 200% = $50,400,000

we check how many layer deep we go:

28,000 - 15,500 at 900= 12,500

12,500  -  6,200  at 800=  6,300

6,300 - 4,100 at 700      =  2,200  at 600

Ending Inventory

The equation of line that passes through the given point and is (a) parallel  to given line is 4x + y - 16 =0

(b) perpendicular to given line is 4x - y -8 =0

According to the question,

The required line is passing through given points and is

(a) parallel (b) perpendicular to given line

Let the equation of required line be (y - y') = m'(x - x')

(a) Parallel

If two lines are parallel to each other then their slopes are equal

Slope of given line : m = y2 - y1 / x2-x1

This line passes through (2,2) and (1,6)

=> m = 6 - 2 / 1 - 2

=> m = -4

Therefore , the slope of required line will be -4 also,

Required line passes through (4,3)

Equation of required line = (y - 4) = -4(x - 3)

=> y - 4 = -4x + 12

=> 4x + y - 16 =0

(b) Perpendicular

If two lines are perpendicular to each other then the product of their slope is -1

So, m × m' = -1

=> -4 × m' = -1

Dividing by -4

=> m' = 4

Therefore , equation of required line =>  (y - 4) = 4(x - 3)

=> y - 4 = 4x - 12

=> 4x - y -8 =0

After solving the logical operations it can be determined that the correct answer is C) FALSE.

Logical operations are phrases that connect expressions to test if they are true or not.

The complement (') sign means that the opposite value of the variable is needed. For example if y is false, y' means true.

Let False = 0 and True = 1

= ((0 OR 0') AND (1' AND 0')) OR ((0 OR 0') AND (1 OR 0)')

= ((0 OR 1) AND (0 AND 1)) OR ((0 OR 1) AND (1)')

= (1 AND 0) OR (1 AND 0)

= 0 OR 0

= 0

Hence, the answer is C) FALSE

we want that time to be less than equation or equal to 5 minutes start text, m, i, n, u, t, e, s, end text. therefore: 1[tex]5minutes[/tex]

Rate for ZZZ Zambonis × Time ≤ 5 minutes

Time ≤ 5 minutes/Rate for ZZZ Zambonis

To solve for the time needed to resurface one rink, we first need to set up an equation. We know that the number of rinks resurfaced by ZZZ Zambonis is equal to the rate for ZZZ Zambonis multiplied by the time. We want the time for 1 rink to be less than or equal to 5 minutes, so we need to solve for time in the equation. We can do this by dividing both sides of the equation by the rate for ZZZ Zambonis, resulting in the equation Time ≤ 5 minutes/Rate for ZZZ Zambonis. This equation gives us the maximum time needed to resurface one rink.

The instantaneous rate of change of daily receipts 13 weeks after the opening day is 1.

To find the instantaneous rate of change of daily receipts 13 weeks after the opening day, you can use the definition of the derivative. The derivative of a function at a point is defined as the limit of the average rate of change of the function over a small interval around that point, as the interval becomes smaller and smaller.

In this case, the function we are interested in is the function that represents the daily receipts of the movie "Avatar" as a function of the number of weeks after the opening day. Let's call this function f(x), where x represents the number of weeks after the opening day.

To find the derivative of f(x) at the point x = 13, we can use the following formula:

f'(x) = lim(h->0) [f(x+h) - f(x)]/h

Plugging in the values, we get:

f'(13) = lim(h->0) [f(13+h) - f(13)]/h

Since we are given the values of the function at various points, we can plug in the values to find the derivative. In this case, we have:

f'(13) = lim(h->0) [(4.027 + h) - 4.027]/h

Simplifying this expression, we get:

f'(13) = lim(h->0) h/h

Since the limit of h/h as h approaches 0 is 1, we can say that:

f'(13) = 1

It's important to note that this result tells us the rate of change of the function at a single point in time, rather than over a longer interval. If we were interested in the average rate of change over a longer interval, we would need to use a different approach.

The number of exams that Gretchen has to take is 4 exams.

From the information illustrated, Gretchen spends 5.1 hours on Monday, 3/3/5 hours on Tuesday, and 5/3/10 hours on Wednesday studying for her final exams. The total hours that she used will be:

= 5.1 + 3 3/5 + 5 3/10

= 5.1 + 3.6 + 5.3

= 14 hours.

Since she spends 3/1/2 hours studying for each exam, the number of exams that she has to take will be:

= Number of hours / Hours used for each exam

= 14 / 3 1/2

= 4 exams

The number of exams are 4.
