How am I supposed to do this?

Answer:

A. Increasing by 4%.

Step-by-step explanation:

Answer:

A) The price of product A is increasing by 3% per year.

(B) The product A recorded a greater percentage change in price over the previous year.

Step-by-step explanation:

(A)

The function representing the price, in dollars, of product A after x years is:

FA(x)=0.69*(1.03)x

The function  FA(x)can be written as:

FA(x)=0.69*1+(0.03)x

The function FA(x) is similar to the exponential growth function, y=a(1+r)x .

Here r is the growth rate.

Thus, it can be said that the price of product A is increasing by 3% per year.

(B)

Consider the data of product B for the year 3 and 4.

The price of product B for year 3 and 4 are 10,303.01 and 10,406.04.

Compute the percent price change from year 3 to 4 as follows:

10406.04-10303.01/10303.01*100

which is 0.999%

~1%

The price of product B is increasing by 1% per year.

Thus, the product A recorded a greater percentage change in price over the previous year.

a) If there are at least 10 bagels of each type, we can calculate the number of different selections of 10 bagels by using the concept of combinations. Since there are 5 types of bagels and we need to select 10 bagels, the calculation can be done as follows:

[tex]\(\binom{10+5-1}{10} = \binom{14}{10}\)[/tex]

b) If there are 3 chocolate chip and 2 cinnamon raisin bagels, and at least 10 of the other three types, we can calculate the number of different selections of 10 bagels using the same concept of combinations. In this case, we have 3 types of bagels (excluding chocolate chip and cinnamon raisin) with at least 10 bagels each. So the calculation becomes:

[tex]\(\binom{10+3-1}{10} = \binom{12}{10}\)[/tex]

Step-by-step explanation:

a. the Laplace transform of a(t) is (28/s^2) + (3/s) + (4/s). b. the Laplace transform of b(t) is 5/s - 10/(s + 2) - 10/(s^3 + 2s^2).

a. To find the Laplace transform of a(t) = 28t + 3 + 4u(t), where u(t) is the unit step function, we can apply the linearity property and the transform of elementary functions.

Applying the linearity property, we can split the transform into three parts:

L{28t} + L{3} + L{4u(t)}

Using the transform of t (L{t} = 1/s^2), we get:

28/s^2 + 3/s + 4/s

Simplifying, we can combine the terms:

(28/s^2) + (3/s) + (4/s)

Therefore, the Laplace transform of a(t) is:

(28/s^2) + (3/s) + (4/s).

b. To find the Laplace transform of b(t) = 5 - 5e^(-2t)(1 + 2t), we can again apply the linearity property and the transform of elementary functions.

Applying the linearity property, we can split the transform into two parts:

L{5} - L{5e^(-2t)(1 + 2t)}

The transform of 5 is simply 5/s.

For the second part, we need to use the transform of e^(-at) and t.

The transform of e^(-at) is 1/(s + a), and the transform of t is 1/s^2.

Using these formulas, we get:

-5/(s + 2)(1 + 2/s^2)

Simplifying and combining terms, we have:

5/s - 10/(s + 2) - 10/(s^3 + 2s^2)

Therefore, the Laplace transform of b(t) is:

5/s - 10/(s + 2) - 10/(s^3 + 2s^2).

Answer:

6(x - 3 ) = 6x - 18

2(3x - 3) = 6x - 6

Step-by-step explanation:

6πa² is the flux of F across the upper hemisphere.

The problem requires us to compute the flux of the given vector field F across the upper hemisphere x² + y² + z² = a², z ≥ 0. We are to orient the hemisphere with an upward-pointing normal. The four vector fields are:

F = yj

F = yi - xj

F = -yi + xj - kz

F = x²i + xyj + xzk

To begin with, we'll make use of the Divergence Theorem, which states that the flux of a vector field F across a closed surface S is equivalent to the volume integral of the divergence of the vector field over the region enclosed by the surface, V, that is:

F · n dS = ∭V (div F) dV

where n is the outward pointing normal unit vector at each point of the surface S, and div F is the divergence of F.

We'll need to write the vector fields in terms of i, j, and k before we can compute their divergence. Let's start with the first vector field:

F = yj

We can rewrite this as:

F = 0i + yj + 0k

Then, we compute the divergence of F:

div F = d/dx (0) + d/dy (y) + d/dz (0)

= 0 + 0 + 0 = 0

So, the flux of F across the upper hemisphere is 0. Now, let's move onto the second vector field:

F = yi - xj

We can rewrite this as:

F = xi + (-xj) + 0k

Then, we compute the divergence of F:

div F = d/dx (x) + d/dy (-x) + d/dz (0)

= 1 - 1 + 0 = 0

So, the flux of F across the upper hemisphere is 0. Let's move onto the third vector field:

F = -yi + xj - kz

We can rewrite this as:

F = xi + y(-1j) + (-1)k

Then, we compute the divergence of F:

div F = d/dx (x) + d/dy (y(-1)) + d/dz (-1)

= 1 - 1 + 0 = 0

So, the flux of F across the upper hemisphere is 0. Lastly, let's consider the fourth vector field:

F = x²i + xyj + xzk

We can compute the divergence of F directly:

div F = d/dx (x²) + d/dy (xy) + d/dz (xz)

= 2x + x + 0 = 3x

Then, we express the surface as a function of spherical coordinates:

r = a, 0 ≤ θ ≤ 2π, 0 ≤ φ ≤ π/2

Note that the upper hemisphere corresponds to 0 ≤ φ ≤ π/2.

We can compute the flux of F over the hemisphere by computing the volume integral of the divergence of F over the region V that is enclosed by the surface:

r² sin φ dr dφ dθ

= ∫[0,2π] ∫[0,π/2] ∫[0,a] 3r cos φ dr dφ dθ

= ∫[0,2π] ∫[0,π/2] (3a²/2) sin φ dφ dθ

= (3a²/2) ∫[0,2π] ∫[0,π/2] sin φ dφ dθ

= (3a²/2) [2π] [2] = 6πa²

Therefore, the flux of F across the upper hemisphere is 6πa².

Answer:

the first one

Step-by-step explanation:

The exact value of A in the general solution is 87/2 and B is 0

From the question, we have the following parameters that can be used in our computation:

y = Ax² + Bx + C

The differential equation is given as

y' = 87x

When y = Ax² + Bx + C is differentiated, we have

y' = 2Ax + B

So, we have

87x = 2Ax + B

By comparing both sides of the equation, we have

2Ax = 87x

B = 0

So, we have

2A = 87

B = 0

Divide both sides of 2A = 87 by 2

A = 87/2

B = 0

Hence, the value of A in the general solution is 87/2 and B is 0

Answer:

The solution is the point (3, -1)

Step-by-step explanation:

We have the system of equations:

x = 3

y + 1 = 0

To solve this graphically, we need to graph these two lines and see in which point the lines intersect.

To graph the line x = 3, we need to draw a vertical line that passes through x = 3.

To graph y + 1 = 0

First we should isolate y.

y = -1

This is graphed as a horizontal line that passes through y = -1

The graph of these two lines can be seen in the image below.

Where the green line is x = 3, and the blue line is y = -1

Now, looking at the graph we can see that the lines do intersect in the point (3, -1)

Then the solution of the system is the point (3, -1)

Answer: C. K= 2.5

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

[tex]\Huge\boxed{k=2.5}[/tex]

Step-by-step explanation:

Given -2.1k + 13 + 6.5k = 24 we need to isolate the variable using inverse operations

step 1 combine any like terms

sometimes there are not like terms but in this case there are. When there are like terms (must be on the same side of the = ) you add them together

-2.1k + 6.5k = 4.4k

now we have

4.4k + 13 = 24

Now we want to get rid of the 13

To do so we subtract 13 from each side

13 - 13 cancels out

24 - 13 = 11

now we have 4.4k=11

now we want to get rid of the 4.4

To do so we divide each side by 4.4

4.4k/4=k

11/4.4=2.5

we're left with k - 2.5

There is only 1 permutation in S9 with a cycle structure of [tex]3^3[/tex].

To find the number of permutations of S9 with a cycle structure of [tex]3^3[/tex], we can use the concept of cycle index.

In a permutation with a cycle structure of[tex]3^3[/tex], we have three cycles of length 3. The cycle index of S9 with respect to cycles of length 3 can be determined using the Polya enumeration theorem.

The cycle index of S9 with respect to cycles of length 3 is given by:

[tex]Z(S9, t1, t2, t3) = (t1^3 + t3^3)^3[/tex]

Expanding this expression, we get:

[tex]Z(S9, t1, t2, t3) = (t1^3 + t3^3)^3\\\= (t1^9 + 3t1^6t3^3 + 3t1^3t3^6 + t3^9)[/tex]

To count the number of permutations with the desired cycle structure, we need to find the coefficient of the term [tex]t1^9t3^9[/tex].

From the expanded form, we see that the coefficient  [tex]t1^9t3^9[/tex] is 1.

Therefore, there is only one permutation in S9 with a cycle structure of [tex]3^3[/tex]

In summary, there is 1 permutation of S9 that has a cycle structure of [tex]3^3[/tex].

Answer : i) The probability of finding the first case in 4 trials is 0.1024                        ii) The probability that the team must select more than 6 people before finding one who has a corona virus is 0.4095.

Explanation : Given information:Let p is the probability that he succeeds in finding such a person, is 0.2 and X denote the number of people asked until the first success.

(i) What is the probability that the team must select 4 people until he finds one who has a corona virus?  

The number of trials required until the first success follows geometric distribution.          

The probability of finding the first case in 4 trials is: P(X = 4) = q^3p, where q = 1 - p.                                                                                                                                     We have p = 0.2 and q = 0.8. So, P(X = 4) = 0.8^3 × 0.2 = 0.1024

(ii) What is the probability that the team must select more than 6 people before finding one who who has a corona virus?                                                                                                                                                                        P(X > 6) = 1 - P(X ≤ 6)                                                                                          The probability of finding the first case in the first 6 trials is:P(X ≤ 6) = 1 - q^6p= 1 - 0.8^6 × 0.2= 0.59049P(X > 6) = 1 - P(X ≤ 6)= 1 - 0.59049= 0.4095                                                                                                                Therefore, the probability that the team must select more than 6 people before finding one who has a corona virus is 0.4095.
