Exponential kind of function best models the set of data points (-3, 18), (-2, 6), (-1, 2), (0, 11), and (1,27).

To figure out which sort of capability best models the given arrangement of pieces of information, we can plot them on a chart and outwardly review the state of the bend that interfaces them.

After plotting the given pieces of information, we can see that the bend that best fits them is certainly not a straight line (direct) or a parabola (quadratic), as it seems to bend all the more steeply. The bend that best fits these focuses is likewise not a steady capability (nothing unless there are other options), as the upsides of y change concerning x.

Consequently, the capability that best models the given arrangement of information focuses is a dramatic capability, which has a bend that increments or diminishes at a speeding up rate. An overall condition for a dramatic capability is:

y =[tex]ab^x[/tex]

where an and b are constants. We can utilize the given focuses to track down the upsides of an and b, and in this manner get the particular condition that models the data of interest.

Answer:

z = -95

Step-by-step explanation:

You simplify both sides of the equation, then isolate the variable.

Applying the definition of a linear pair, the value of n is calculated as: n =  41.33.

A linear pair consist of two angles that are on a straight line and also have a sum of 180 degrees.

The missing diagram is in the attachment provided below which shows the angles in question.

Angle 1 and (3n - 6) are two angles on a straight line, therefore, they are a linear pair. This also implies that they will have a sum of 180 degrees.

Therefore, we have:

The equation of the line, in point-slope form, that passes through (1, -7) and has a slope of -2/3 is y + 7 = -2/3 (x − 1).

Option A is the correct answer.

We have,

The point-slope form of a linear equation is:

y - y1 = m(x - x1)

where (x1, y1) is a point on the line and m is the slope of the line.

Now,

Given that the line passes through the point (1, -7) and has a slope of -2/3, we can substitute these values into the point-slope form:

y - (-7) = (-2/3)(x - 1)

Simplifying the equation:

y + 7 = (-2/3)x + (2/3)

Subtracting 7 from both sides:

y = (-2/3)x - (19/3)

So,

y + 7 = -2/3 (x - 1)

Answer:

Step-by-step explanation:

(NM)v_i = N(Mv_i) = Nv_i = v_i.

Thus, MN = NM = I, as required.

Yes, such a matrix N exists.

Since M^2 = M, we can write M(M - I) = 0. Therefore, the only possible eigenvalues of M are 0 and 1.

If M has any eigenvalue equal to 0, then the determinant of M is 0, which is not possible according to the problem statement. Hence, all eigenvalues of M are 1.

Since M is a 10 x 10 matrix, it must have a basis of 10 linearly independent eigenvectors corresponding to the eigenvalue 1. Let v1, v2, ..., v10 be such eigenvectors.

Now, we can define N as follows:

For any i and j, if i = j, then Nv_i = v_i.

For any i and j, if i ≠ j, then Nv_i = v_j.

It is easy to verify that this N satisfies MN = NM = I, the identity matrix.

To see this, note that for any i,

(MN)v_i = M(Nv_i) = Mv_i = v_i

and

(NM)v_i = N(Mv_i) = Nv_i = v_i.

The large drain can empty the tank on its own in 10 hours, while the small drain can empty the tank on its own in 16 hours.

Let's assume that the large drain can empty the tank in x hours. Then, according to the problem statement, the small drain can empty the same tank in x + 6 hours.

When both the large and small drains are opened together, they can empty the tank in 4 hours. This means that their combined rate of emptying the tank is 1/4 tank per hour.

We can set up two equations based on the rates of the individual drains and their combined rate:

1/x + 1/(x+6) = 1/4

Solving for x, we get x = 10 hours, which is the time it takes for the large drain to empty the tank on its own.

To find the time it takes for the small drain to empty the tank on its own, we substitute x = 10 in x+6, which gives us 16 hours.

Therefore, the large drain can empty the tank on its own in 10 hours, while the small drain can empty the tank on its own in 16 hours.

The equilibrium quantity of a follower firm in a market with a leading firm that produces the monopoly quantity is determined by the follower's reaction function. Specifically, the follower will choose a quantity that maximizes its profit given the quantity chosen by the leader.

Assuming that the follower's cost function is linear, the equilibrium quantity can be expressed as a function of the leader's quantity. Let Qf denote the quantity chosen by the follower and Ql denotes the quantity chosen by the leader. The follower's profit function can be written as:

πf = (P(Qf) - c)Qf

where P(Q) is the market price as a function of the total quantity produced (Q = Qf + Ql) and c is the follower's unit cost. The first-order condition for profit maximization is:

∂πf / ∂Qf = P(Qf) + Qf ∂P / ∂Q - c = 0

Solving for Qf, we get:

Qf = (1 / 2) (Qm - Ql)

where Qm is the monopoly quantity produced by the leader. This expression shows that the follower's equilibrium quantity is half of the deviation between the monopoly quantity and the quantity chosen by the leader. In other words, the follower's quantity is determined by the leader's deviation from the monopoly quantity.

Overall, the expression for the equilibrium quantity of a follower firm in a market with a leader that produces the monopoly quantity is Qf = (1 / 2) (Qm - Ql), where Qm is the monopoly quantity and Ql is the quantity chosen by the leader. This result highlights the strategic interdependence between the leader and the follower and the importance of anticipating each other's actions in a competitive market.

x^2J"n(x) = (n^2 - n)J_n(x) - xJ_(n+1)(x) + (n+2)x^2J_n(x) + 2nxJ_(n+2)(x) + (d/dx)^(n-2) [xJ_n(x) +

To prove the given identity, we will start with the following expression:

x^2J_(n+1)(x) = xJ_n(x) + xJ_(n+2)(x) (Recurrence relation for Bessel functions)

Now, let's differentiate both sides of the above equation n times with respect to x:

(d/dx)^n [x^2J_(n+1)(x)] = (d/dx)^n [xJ_n(x)] + (d/dx)^n [xJ_(n+2)(x)]

Using the Leibniz rule for differentiating products, we can expand each term on the right-hand side:

(d/dx)^n [x^2J_(n+1)(x)] = x(d/dx)^n [J_n(x)] + n(d/dx)^(n-1) [J_n(x)] + (d/dx)^(n-2) [J_n(x)] + x(d/dx)^n [J_(n+2)(x)] + 2n(d/dx)^(n-1) [J_(n+2)(x)] + (d/dx)^(n-2) [J_(n+2)(x)]

Now, we can use the recurrence relation for Bessel functions on the terms involving J_n(x) and J_(n+2)(x):

(d/dx)^n [x^2J_(n+1)(x)] = xJ_(n-1)(x) + nJ_(n-1)(x) + (d/dx)^(n-2) [J_n(x)] + xJ_(n+3)(x) + 2nJ_(n+3)(x) + (d/dx)^(n-2) [J_(n+2)(x)]

We can simplify the above expression using the following identity:

(d/dx)^n [xJ_n(x)] = xJ_(n-n)(x) + nJ_(n-1)(x)

Substituting this identity into the above equation, we get:

(d/dx)^n [x^2J_(n+1)(x)] = xJ_n(x) + nJ_n(x) - nJ_(n-1)(x) + xJ_(n+2)(x) + 2nJ_(n+2)(x) + (d/dx)^(n-2) [J_n(x) + J_(n+2)(x)]

Next, we can multiply both sides of this equation by x^2 and simplify using the identity:

(n+1)J_n(x) = xJ_(n+1)(x) + xJ_(n-1)(x)

Multiplying both sides by x and substituting the resulting expression into the previous equation, we obtain:

x^2J"n(x) = (n^2 - n)J_n(x) - xJ_(n+1)(x) + x^2J_(n+2)(x) + 2nxJ_(n+2)(x) + (d/dx)^(n-2) [xJ_n(x) + xJ_(n+2)(x)]

Now, we can use the recurrence relation for Bessel functions on the terms involving J_(n+2)(x):

Step-by-step explanation:

Probability is a measure of the likelihood of an event occurring. In this case, the event is selecting a chocolate chip cookie from the batch of chocolate chip, oatmeal raisin, and sugar cookies made by the baker.

The probability of selecting a chocolate chip cookie is given as P(chocolate chip) = 0.75.

This means that out of all the cookies in the batch, 75% are chocolate chip cookies.

Since this probability is greater than 0.5 (which represents an event that is equally likely and unlikely), we can interpret it as indicating that it is likely to randomly select a chocolate chip cookie from the batch. In other words, if we were to randomly select a cookie from the batch, it is more likely that we would get a chocolate chip cookie than any other type of cookie.

Therefore, the correct answer is B) Likely.
