At what points does the helix r(t) = sin(t), cos(t), t intersect the sphere x2 + y2 + z2 = 26? (round your answers to three decimal places. If an answer does not exist, enter dne. ).

Answer:

 44 ft

Step-by-step explanation:

You want to know the height of a tree whose top is at angles of elevation of 42° and 50° from points 12 feet apart.

The tangent of an angle is related to the side lengths of a right triangle by ...

  Tan = Opposite/Adjacent

This tells us the length of the side adjacent to the angle of elevation is ...

  Adjacent = Opposite/Tan

Here, the height of the tree is the side of the triangle opposite the angle of elevation, and the difference of adjacent sides is 12 ft:

  12 = h/tan(42°) -h/tan(50°)

  h = 12/(1/tan(42°) -1/tan(50°)) ≈ 12/(1.11061 -0.83910) ≈ 44.197

The approximate height of the tree is 44 feet.

Answer: [tex](0.2,2)[/tex]

Step-by-step explanation:

[tex]-5x-y=-3[/tex]

add y on both side of the equation

[tex]-5x=y-3[/tex]

add 3 on both side of the equation

[tex]y=-5x+3[/tex]

Then insert [tex]-5x+3[/tex] as y in the equation [tex]y =5x+1[/tex]

[tex]5x+1=-5x+3[/tex]

add 5x on both side of the equation

[tex]10x+1=3[/tex]

minus 1 on both side of the equation

[tex]10x=2[/tex]

divide by 10 on both side of the equation

[tex]x=0.2[/tex]

That is how you get x

To get y, you would sub 0.2 for x in the equation [tex]y=5x+1[/tex] or[tex]-5x-y=-3[/tex], I prefer the first equation

[tex]y=5x+1[/tex]

sub 0.2 for x

[tex]y=5(0.2)+1[/tex]

multiply 5 by 0.2

[tex]y=1+1[/tex]

add them up

[tex]y=2[/tex]

and there you go for y

What is least common multiple ?

The least common multiple (LCM) of two or more numbers is the smallest number that is a multiple of all the given numbers. In other words, it is the smallest number that is divisible by all the given numbers without leaving a remainder.

To find the LCM of two or more numbers, you can list their multiples and look for the smallest number that appears in all the lists. However, this can become time-consuming for large numbers. There are various methods and algorithms to find the LCM efficiently, such as using prime factorization or the Euclidean algorithm.

According to the question:
Allergy Sufferer #1 takes 1 capsule every 6 hours, so in 45 capsules, they will need to take 45 * 6 = 270 hours.

Allergy Sufferer #2 takes 1 capsule every 12 hours, so in 45 capsules, they will need to take 45 * 12 = 540 hours.

To find the total time it will take them together to consume 45 capsules, we need to find the least common multiple (LCM) of 6 and 12.

The prime factors of 6 are 2 and 3.

The prime factors of 12 are 2, 2, and 3.

To find the LCM, we take the highest power of each prime factor that appears in either factorization. In this case, that's 2^2 * 3 = 12.

So, the LCM of 6 and 12 is 12.

This means that every 12 hours, Allergy Sufferer #1 will have taken 2 capsules (since 12/6=2), and Allergy Sufferer #2 will have taken 1 capsule.

Therefore, in 12 hours, they will have taken a total of 2+1=3 capsules.

So, to consume 45 capsules, it will take them 45/3 = 15 lots of 12 hours, which is 180 hours in total.

Residual sum of squares (RSS) is a measure of the total amount of variance in a given data set that is not explained by a model.

It is equal to the sum of squared differences between the observed data values and the predicted values from the model. This measure is commonly used in regression analysis to evaluate the performance of a model. The formula for RSS is  RSS = Σ(y_i - ȳ)², where y_i is the observed value and ȳ is the predicted value.For example, let's say we have a data set of 10 observations (y_1, y_2, ...,y_10). We fit a linear regression model to the data set which predicts a value ȳ_i for each observation. The RSS for this model is calculated by summing the squared differences between the observed values (y_i) and the predicted values (ȳ_i) for each of the 10 observations. This yields the RSS, which is a measure of how much of the variance of the data set is not explained by the model.

The solution is Option A.

The transformed equation is y = -x - 8

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units: y=f(x+c) (same output, but c units earlier)

Right shift by c units: y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the parent function be represented as A

Now , the value of A is

f ( x ) = x or y = x

Now , when the function is reflected over the y-axis , the x coordinate of the function is changed to its additive inverse

So , reflected function is g ( x ) = -x

Now , when the function is translated down 8 units ,

The pool water will be 0.006% chlorine after approximately 236.5 minutes, and the percentage of chlorine in the pool after 1 hour (60 minutes) is approximately 0.674%.

Let C(t) be the amount of chlorine in the pool at time t in minutes, measured in gallons of chlorine. Since the volume of the pool is 10,000 gal and the initial concentration of chlorine is 0.01%, we have:

C(0) = 10,000 gal x 0.01% = 1 gal

As city water containing 0.003% chlorine is pumped into the pool at a rate of 6 gal/min and the pool water flows out at the same rate, the differential equation for C(t) is:

dC/dt = (0.003 - C(t)/10,000) x 6 - C(t)/10,000 x 6

Simplifying the right-hand side and solving the differential equation using separation of variables, we get:

C(t) = 30,000(1 - e^(-t/166.7)) - 180,000e^(-t/166.7)

After 1 hour (60 minutes), we have:

C(60) = 30,000(1 - e^(-60/166.7)) - 180,000e^(-60/166.7) ≈ 0.0674 gal

The percentage of chlorine in the pool after 1 hour is:

0.0674 gal / 10,000 gal x 100% ≈ 0.674%

To find when the pool water is 0.006% chlorine, we set C(t) = 10,000 gal x 0.006% = 0.6 gal and solve for t:

30,000(1 - e^(-t/166.7)) - 180,000e^(-t/166.7) = 0.6

Using numerical methods, we find that t ≈ 236.5 minutes.

After roughly 236.5 minutes, the chlorine content of the pool will be 0.006%, and after an hour (60 minutes), it will be approximately 0.674%.

The mean is 11.25 and median is 8, and from the employees' perspective, the median would be a better measure of central tendency to use for determining the raise cut-off point.

{1, 4, 5, 6, 7, 9, 9, 11, 15, 18, 27, 32}

The mean is the average value of the dataset. We can find the mean by summing up all the values and dividing by the total number of values:

mean = (1 + 4 + 5 + 6 + 7 + 9 + 9 + 11 + 15 + 18 + 27 + 32) / 12

= 135 / 12

= 11.25

Therefore, the mean of the dataset is 11.25.

The median is the middle value in the dataset. If the dataset has an odd number of values, the median is the middle value. If the dataset has an even number of values, the median is the average of the two middle values.

In this case, the dataset has 12 values, so we need to find the average of the 6th and 7th values:

median = (7 + 9) / 2

= 8

Therefore, the median of the dataset is 8.

From the employees' perspective, the median would be a better measure of central tendency to use for determining the raise cutoff point. This is because the median is not affected by outliers as much as the mean.

In this dataset, the value of 32 is much larger than the other values and could skew the mean upward, which would result in a higher cutoff point for the raise. On the other hand, the median is not affected by the outlier and provides a better representation of the central value of the dataset.
