This will generate the desired sequence [1] 10 9 8 7 6 9 8 7 6 5 8 7 6 5 4 7 6 5 4 3 6 5 4 3 2. In this sequence, the numbers decrease from 10 to 1, then increase from 9 to 1, and so on.

The given sequence [1] 10 9 8 7 6 9 8 7 6 5 8 7 6 5 4 7 6 5 4 3 6 5 4 3 2 cannot be generated using only the seq() and rep() functions because it involves a more complex pattern than the sequences generated using seq() and rep() alone. In this sequence, the numbers decrease from 10 to 1, then increase from 9 to 1, and so on.

To generate this sequence, you can use the c() function in addition to seq() and rep(). The c() function is used to combine different elements or vectors into a single vector. Here is how you can generate this sequence:

1. Start by creating the decreasing sequence from 10 to 1 using seq() function:
  seq(10, 1)

2. Next, create the increasing sequence from 9 to 1 using seq() function:
  seq(9, 1)

3. Combine the above two sequences using the c() function:
  c(seq(10, 1), seq(9, 1))

4. Repeat the combined sequence 6 times using rep() function:
  rep(c(seq(10, 1), seq(9, 1)), times = 6)

Answer:

p = 3 and q = - 4

Step-by-step explanation:

Substitute the coordinates of the solution (2, - 3 ) into the equations and solve for p and q

px + y = 3 , then

2p - 3 = 3 ( add 3 to both sides )

2p = 6 ( divide both sides by 2 )

p = 3

and

x + 2y = q , then

2 + 2(- 3) = q

2 - 6 = q , so

q = - 4

Where is the question?

Answer: There are 375 star stickers and 125 heart stickers.

There are 500 stickers with 20 stickers per sheet; 500/20 = 25 sheets of stickers.

25% of each sheet is hearts; 25/100(20) = 5 heart stickers per sheet.  5(25) = 125 total heart stickers.

20 stickers per sheet - 5 heart stickers per sheet = 15 star stickers per sheet.  15(25) = 375 total star stickers.

The values of x for which the function f(x) = x³ + 3x² - 9x + 7 is increasing are (-∞, -3) and (1, +∞).

To find the values of x for which the function f(x) = x³ + 3x² - 9x + 7 is increasing, we need to take the derivative of the function and determine where the derivative is positive.

f(x) = x³ + 3x² - 9x + 7

f'(x) = 3x² + 6x - 9

To find where f(x) is increasing, we need to find the values of x where f'(x) > 0.

3x² + 6x - 9 > 0

Simplifying this inequality, we get

x² + 2x - 3 > 0

Factoring the left side of the inequality, we get

(x + 3)(x - 1) > 0

The critical points of f(x) occur when f'(x) = 0 or when the denominator of f'(x) is undefined. The denominator of f'(x) is always defined, so we only need to find where f'(x) = 0

3x² + 6x - 9 = 0

Dividing both sides by 3, we get

x² + 2x - 3 = 0

Factoring the left side of the equation, we get

(x + 3)(x - 1) = 0

So the critical points of f(x) are x = -3 and x = 1.

Now we can use a sign chart to determine the intervals where f'(x) > 0.

The probability that fewer than 60 adults will work from home will be 2%.    

we have to use the Normal probability distribution to find the probability

In a normal distribution with mean μ, SD σ, z-score Z of a measure X  is given by

Z = (X-μ)/ σ

here,

15% adults work from home , So  p= 0.15

                                                       n = 500

∴  μ = np = 500(0.15) = 75

σ  = \(\sqrt{np(1-p)}\)

σ = 7.98

Now we have  selected adults(60) less than n (500)

So using the continuity correction , the probability is P(X< 60 - 0.5)

                                                                            = P( X< 59.5)

which is the p-value of Z when X = 59.5

∴ Z = (X-μ)/ σ

Z  =  (59.5 - 75)/7.98

Z =   - 1.98

so the p-value is 0.02

0.02 = 2% probability that fewer than 60 adults will work from home.

Answer:

To determine the number of batches of blueberry muffins that Nina can make, we need to set up an inequality. Let x be the number of batches of blueberry muffins that Nina can make.

We know that 1.5 cups of blueberries are needed for each batch of blueberry muffins. Therefore, the total number of cups of blueberries used for x batches of blueberry muffins is 1.5x.

Nina wants to keep at least 4 cups of blueberries to make a blueberry pie. So, we have:

18 - 1.5x >= 4

Simplifying the inequality:

1.5x <= 14

x <= 9.33

Since Nina can only make a whole number of batches of blueberry muffins, she can make at most 9 batches of muffins (option B).

The height of the ball as a function of the time is given by the following formula:

A. Maximum height of the ball

To find the value of the maximum height, we maximum the function h(t) computing its first derivative and equalling the result to zero:

Solving the last equation for t, we get time t when the height is maximum:

So the maximum height is given by the value of h(t) when t = 2.5:

The maximum height is 196ft.

B. Time until the ball hits the ground

The ball will hit the ground when h(t) = 0. So we must find the value of t such that:

Solving this equation is equivalent to finding the roots of a second-order polynomial:

Where:

• a = -16,

• b = 80,

• c = 96.

Calculate the power consumption of the device-The power consumption of the device can be calculated using the formula: Power = Voltage x Current. P = V x I, Substituting the given values:

P = 110V x 0.12A

= 13.2 W

Calculate the cost per second-The cost per second can be calculated using the formula:

Cost per second = Power x Cost per Joule

C = P x CC

= 13.2 W x 1.8 x \(10^-7\) $/J

The function\(f(x, y) = (x^2 + y^2)e^((y^2) - x^2)\) has three critical points. Their coordinates are (0, 0), (-1, 0), and (1, 0). The critical point (0, 0) is a saddle point, while the critical points (-1, 0) and (1, 0) are local minima.

To find the critical points, we need to determine the values of x and y for which the partial derivatives of f(x, y) with respect to x and y are both zero. Taking the partial derivatives, we hav

∂f/∂x = \(2xe^((y^2) - x^2) - 2xe^((y^2) - x^2) - 2xy^2e^((y^2) - x^2) = 0\)

∂f/∂y = \(2ye^((y^2) - x^2) - 2ye^((y^2) - x^2) + 2xye^((y^2) - x^2)(2y) = 0\)

Simplifying the equations, we get:

\(2xe^((y^2) - x^2) - 2xy^2e^((y^2) - x^2) = 0 (1)\)

\(2ye^((y^2) - x^2) + 4xy^2e^((y^2) - x^2) = 0 (2)\)

From equation (1), we can see that either x = 0 or e^((y^2) - x^2) - y^2e^((y^2) - x^2) = 0.

For x = 0, substituting in equation (2) gives \(2ye^((y^2)\) - 0) = 0, which implies y = 0. Therefore, the critical point (0, 0) is found.

For\(e^((y^2) - x^2) - y^2e^((y^2) - x^2)\)= 0, we can factor out e^((y^2) - x^2) and obtain:

\(e^((y^2) - x^2)(1 - y^2) = 0\)

This equation holds true when either \(e^((y^2) - x^2) = 0 or 1 - y^2 = 0.\)

Since \(e^((y^2) - x^2)\) cannot be zero, we have 1 - y^2 = 0, which implies y = ±1.

Substituting y = ±1 into equation (1) gives x = ±1.

Therefore, the critical points are (0, 0), (-1, 0), and (1, 0).

\(f^{-1} (x) = \sqrt[3]{\frac{1 - 9x^{2} }{x^{2} } }\)

Step-by-step explanation:

Let f(x) = y

Interchange x and y so

\(x = \frac{1}{\sqrt{y^{3} + 9 } }\)

\(x\sqrt{y^{3} + 9} = 1\)

\(\sqrt{y^{3} + 9 } = \frac{1}{x}\)

\(y^{3} + 9 = \frac{1}{x^{2} }\)

\(y^{3} = \frac{1}{x^{2} } - 9\) = \(\frac{1 - 9x^{2} }{x^{2} }\)

\(y = \sqrt[3]{\frac{1 - 9x^{2} }{x^{2} } }\)

\(f^{-1} (x) = \sqrt[3]{\frac{1 - 9x^{2} }{x^{2} } }\)
